Full Text Available We report a case of mixed capillary venous hemangioma of the retroperitoneum in a 61-year-old man. Abdominal ultrasonography showed a mass to be hypoechoic with increased flow in color Doppler imaging. Dynamic contrast-enhanced computed tomography revealed a centripetal filling-in of the mass, located anterior to the left psoas muscle at the level of sacroiliac joint. On the basis of imaging features, preoperative diagnosis of hemangioma was considered and the mass was excised by laparoscopic method. Immunohistochemical studies were strongly positive for CD31 and CD34, and negative for calretinin, EMA, WT1, HMB45, Ki67, synaptophysin, and lymphatic endothelial cell marker D2–40. Histologically, the neoplasm was diagnosed as mixed capillary venous hemangioma.

This paper defines the MR characteristics of head and neck hemangiomas and to evaluate the role of MR in their diagnosis and management. Eighteen pediatric and young adult patients with head and neck hemangiomas (six neck, six face, three eyelid, two scalp, and one parotid) underwent high-field-strength 1.5-T MR imaging. Conventional spin-echo sequences with T1 and T2 weighting were performed. In addition, one-third of patients underwent MR angiography and gadolinium enhancement. The hemangiomas were isointense to muscle on T1-weighted images and hyperintense on proton-density and T2-weighted images

Radium and roentgen therapies for hemangiomas of the skin (mainly strawberry hemangiomas) were used between 1909 and 1959 at Radiumhemmet, Stockholm. The total number of admitted patients with hemangioma of the skin during this period was 20012. About 90% were treated with irradiation and radium therapy was the most commonly used modality. Needles, tubes and flat applicators containing radium were used. Roentgen therapy was given by using standard machines available at the time. A small number of patients were treated with 32 P plaques. Most hemangiomas were located in the head-neck region (47%) and 30% were located on the thorax and upper part of the abdomen. The median age at the first treatment was 6 months and 90% of all patients were younger than 2 years of age at the time of treatment. The purpose of the investigation was to define a cohort, useful for studies on possible late effects following exposure to ionizing radiation in childhood. (orig.)

The authors present an extremely rare case of an aggressive and progressive vertebral capillary hemangioma of the lumbar spine secondary to a trauma. A 40-year-old man who complained of back and leg pain due to a hemangioma of L1 that had begun a year after the fracture of the same vertebra was subsequently operated on. Due to the profuse bleeding, only a subtotal removal was possible. Histopathological diagnosis of the lesion revealed a capillary hemangioma. Postoperative control MRI taken at eight months showed that the lesion and destruction of the L1 vertebra were progressive. A second embolization procedure was performed and this time the hemangioma was totally removed via an anterior approach and corpectomy. Fusion was achieved by Th12-L2 graft and plaque. In the fourteenth year of follow-up, he was symptom-free and radiologically clear of this lesion. We propose that progressive hemangioma is extremely rare and that its cure is possible by total surgical removal of the lesion. This case is the second extradural capillary hemangioma secondary to spinal trauma ever to have been documented in English literature. The emergence of a hemangioma in a fractured vertebra suggests that its pathogenesis can be related to the deviation of the angiogenetic pathways from the normal healing process. PMID:28713608

To investigate the association between the size of the hepatic hemangioma and the shape and thickness of the echogenic rim of hepatic hemangioma on abdominal ultrasound. We examined 47 cases (M:F=24:23, mean age 47.1) of hepatic hemangiomas with echogenic rim on abdominal ultrasound during the past 2 years. Radiologic findings were retrospectively reviewed in terms of completeness and thickness of echogenic rim. If echogenic rim showed even thickness, it was measured. But if not, the maximum and minimum thickness of the rim was measured. The association between the size of hemangioma and the completeness and thickness of the echogenic rim were analyzed statistically. Of the 47 cases, complete echogenic rim and incomplete echogenic rim were obtained in 29 (62%) and 18 (38%) cases, respectively. Twenty-two cases of hemangioma were less than 2 cm in diameter, and their distribution according to echogenic rim were as follows: complete echogenic rim (17/20, 91% mean thickness 2.2 cm) and uneven thickness with complete echogenic rim (3/20, 15%, range:2.0-6.1 mm). Twenty-five hemangiomas were larger than 2 cm in diameter and their distribution according to echogenic rim were as follows: complete echogenic rim (n=9, 34%), incomplete echogenic rim (n=16, 64%0,even thickness with complete echogenic rim (3/9, 33%, mean thickness 2.2 mm) and uneven thickness with complete echogenic rim (6/9,67%, range: 2.0-7.6 mm). In statistical analysis, hemangiomas more than 2 cm in diameter were more likely to have incomplete echogenic rim (p<0.05) than those of less than 2 cm; hemangiomas more than with more than 2 cm in diameter and complete echogenic rim showed uneven thickness of echogenic rim (p<0.05), more often than those of less than 2 cm diameter. Hemangiomas with more than 2 cm in diameter showed more frequent incomplete echogenic rim than those of less than 2 cm in diameter, which had more frequent complete echogenic rim. Hemangiomas with complete echogenic rim and even rim

Typical cavernous hemangioma presents no diagnostic difficulty at sonography. However, in cases of atypical hemangioma, further evaluation is needed to differentiate it from malignancy. On the other hand, thcechogenicity of the lesion may be iso echo or hypoecho when it occurs in association with fatty liver. We analyzed the sonographic features of hemangioma in fatty liver. We reviewed the sonograms of 22 lesions from 19 patients. We divided the lesions into two groups; the lesion measuring less than 3cm in diameter (group I) and the lesions measuring same or greater than 3cm (group II). The lesions of each group were analyzed in terms of location, shape, distinction of margin, internal echogenicity, posterior enhancement, lateral shadowing, and peritumoral hypoechoic halo. The lesions were located in subcapsular or perivascular areain 86%. They strowed round or lobulated shape with well defined margin in 82%. Internal echo of the lesions was hypoechoic in 82% and homogeneous in 64%. Posterior enhancement was seen in 77%. The posterior wall of the lesion was distinct in 68%. There was no statistical difference in incidence of each finding described above between the two groups except the internal echogenicity(p<0.05). All of the four hyperechoic lesions measured greater than 3cmin diameter, and three of them showed uneven thickness of echogenic rind. Definitive diagnosis of hemangioma could be obtained in 82%. In remaining 18% of hemangioma, the lesions showed peripheral hypoechoic halo and lateral shadowing that made the diagnosis of hemangioma difficult. However, the possibility of hemangioma could be suggested because they showed haemangiomas internal eye-catching and posterior enhancement. Hepatic cavernous hemangioma presents with variable eye-catching as compared to the surrounding tissue when it is associated with fatty liver disease, Thus, in differentiating hemangiomas from other localized hepatic mass, other characteristics such as homogeneity of the

Full Text Available Some infantile hemangiomas called in literature “minimal or arrested growth hemangiomas” or “abortive hemangiomas” are present at birth and have a proliferative component equaling less than 25% of its total surface area. Often, they are mistaken for vascular malformation. We present five patients (three girls and two boys with abortive hemangiomas diagnosed between January 2010 and December 2015 localized in acral part of the extremities. They were congenital lesions resembling precursor of hemangiomas but did not show proliferation phase. Immunohistochemical Glut-1 was performed in all of them as a way to confirm the abortive hemangioma diagnosis. The most common appearance was a reticulated erythematous patch with multiple fine telangiectasias on the surface. We remark that one of them presented a segmental patch with two different morphologies and evolutions. The proximal part showed pebbled patches of bright-red hemangioma and presented proliferation and the distal part with a reticulated network-like telangiectasia morphology remained unchanged. We detected lower half of the body preference and dorsal region involvement preference without ventral involvement. The ulceration occurred in three patients with two different degrees of severity.

2000-01-01

Cavernous hemangioma is the most common benign hepatic tumor. Typically, the most common features revealed by ultrasound (US) include its small size (4 cm or less in diameter), uniform hyperechogenicity, well defined margins, position in the subcapsular region of the right lobe of the liver, and some posterior echo enhancement. In addition, follow-up scanning may reveal changes in size, though this is rare. The US findings of hepatic hemangiomas may vary, however, especially when lesions are large and/or multiple. For that reason, differential diagnosis between this condition and hepatocellular carcinomas, metastatic lesions, lymphomas and other tumors is difficult. An understanding of the various sonographic findings of hepatic hemangioma can facilitate the early detection of the condition. (author)

Full Text Available Intra-muscular hemangiomas (IMH are relatively uncommon benign vascular tumors, which account for less than 1% of all hemangiomas. IMH may be presented as a perceived sporting injury. Diagnosis of this lesion is important not only because of its rarity, but also due to dangers posed by misdiagnosis and mismanagement. They must be considered in the differential diagnosis of unexplained pain and swelling in muscles. IMH occurring in the oral cavity is reviewed below.

Full Text Available Purpose: To discuss our treatment results of choroidal hemangiomas. Material and Method: The records of 39 cases of choroidal hemangioma followed up at our clinic between July 1999–October 2012 were reviewed retrospectively. Asymptomatic cases were followed up. Symptomatic cases with subretinal fluid and impaired vision received treatment. Results: Mean age of the 39 patients was 44 (12-80 years. Thirty-five of 39 cases had circumscribed choroidal hemangioma, and 4 cases had diffuse choroidal hemangioma. Sturge-Weber syndrome was present in 3 cases with diffuse choroidal hemangioma. Cases with circumscribed choroidal hemangioma and minimal subretinal fluid were treated with TTT in 11 cases, PDT in 12 cases, and PDT+TTT in 1 case. Cases with circumscribed choroidal hemangioma and excessive subretinal fluid were treated with Ru-106 plaque radiotherapy in 1 case, Ru-106 plaque radiotherapy+TTT in 1 case, EBRT in 3 cases, and TTT+EBRT in 1 case. One painful blind eye with neovascular glaucoma and complicated cataract was enucleated. Cases with diffuse choroidal hemangioma and excessive subretinal fluid were treated with Ru-106 plaque radiotherapy+TTT in 1 case and EBRT in 1 case. Ahmed glaucoma valve implantation and FAKO emulsification were applied to a case with neovascular glaucoma and complicated cataract. Complete resorption of subretinal fluid was achieved in 23 (72% of treated 32 cases. When mean initial tumor thickness was 2.6 mm (0.5-6, mean final tumor thickness was 1.4 mm (0-6. When mean initial visual acuity (LogMAR was 1.5 (0-3, mean final visual acuity was 1.1 (0-3. No recurrence was observed. Discussion: The amount of the subretinal fluid determines the method of treatment in circumscribed choroidal hemangioma. While TTT and PDT are effective treatment modalities for minimal subretinal fluid, plaque radiotherapy and EBRT are applied in cases with excessive subretinal fluid. Combination therapies may be necessary according to the

Eleven patients with hemangioma in the oral cavity were studied by MR imaging using spin-echo T 1 - and fast SE T 2 -weighted sequences. The hemangioma was iso-intense to muscles on T 1 -weighted images, and markedly hyperintense on T 2 -weighted images. The lesions were lobulated in margin. Four lesions showed internal spotty and/or curvilinear structures of low signal intensity. After administration of Gd-DTPA, three of seven lesions showed uniform contrast enhancement, three lesions showed partial or marginal enhancement, and remaining one lesion did not show enhancement effect. We conclude that MR imaging of oral hemangiomas is useful in delineating extent of the lesion. (author)

The synovial hemangioma is an uncommon benign vascular tumor that is difficult to diagnose on the basis of clinical signs Moreover, it has no characteristic radiographic features. The objective of the present report was to describe the MR findings associated with synovial hemangioma of the knee. We review the clinical and MR findings in six patients, with histologically confirmed synovial hemangioma of the Knee, studied with different MR systems and techniques. Synovial hemangiomas were isointense with respect to muscle in T1-weighted images, strongly hyperintense in T2-weighted sequences and presented wavy hypointense linear images. Gadolinium administration resulted in a marked enhancement, although it was heterogeneous in two of three cases analyzed. Although the findings are not pathognomonic, the presence of an intraarticular tumor of the knee that is isointense with respect to muscle in T1 and hyperintense in T2, and shows wavy hypointense images and a marked contrast uptake, may suggest the presence of synovial hemangioma.

Hemangioma is the most common soft tissue tumor in the body. Though it may occur anywhere in the body, hemangioma of the uterus is a very rare tumor. Hemangioma is almost asymptomatic, but it is sometimes clinically important because it can cause massive hemorrhage and this is a life-threatening condition. We report here on the magnetic resonance imaging and pathologic findings of cavernous hemangioma of the uterus in a 32-year-woman with menorrhagia.

They occur more frequently in female infants. The cause of hemangioma is currently unknown; however, current studies suggested the importance of estrogen (E2 signaling in hemangioma proliferation. Methods: Hemangioma-derived stem cells (HemSCs were cultured with estrogen for 48–72 h; the cell viability and proliferation were evaluated with the messenger RNA (mRNA and protein expression levels of fibroblast growth factor 2 (FGF2, vascular endothelial growth factor-A (VEGF-A and estrogen receptor-α (ER-α, by application of several in vitro assays, such as methyl thiazolyl tetrazolium (MTT, reverse transcriptase–polymerase chain reaction (RT-PCR, real-time PCR, enzyme-linked immunosorbent assay (ELISA and Western blotting. Also, the cell population’s response to external estrogen was investigated by in vivo experiments. HemSCs and human umbilical vein endothelial cells (HUVECs were mixed and injected subcutaneously into 20 flank of BALB/c-nu mice, which were randomly divided into 5 groups based on different E2 treatment doses (0, 0.01, 0.1 and 1 mg, respectively, 0.1 mg dimethyl sulfoxide (DMSO as control. Each group of mice were treated intramuscularly every week, then 2 and 4 weeks later, the subcutaneous implants were harvested and evaluated the tumor tissues with microvessel density (MVD assay and immunohistochemistry.

Congenital hemangiomas (CH) are benign vascular neoplasms that proliferate in utero and have completed development by birth. Two subtypes of CH are recognized: rapidly involuting congenital hemangiomas (RICH) and non-involuting congenital hemangiomas (NICH). Involution of the RICH subtype often begins in the first weeks of life. NICH does not involute, allowing the distinction between RICH and NICH. We report a case of an infant with RICH occurring on the scalp, examined at birth and followed...

Intraosseous hemangioma is an extremely rare tumor that accounts for 1% or fewer of all osseous tumors. The most common sites of its occurrence are the vertebral column and calvaria. Occurrence in a facial bone is very rare. The authors aim to report a case of the surgical treatment of intraosseous hemangioma occurring in the periorbital region, which is a very rare site of occurrence and to introduce our own experiences with the diagnosis and treatment of this condition along with a literature review. A 73-year-old male patient visited our hospital with the chief complaint of a mass touching the left orbital rim. A biopsy was performed by applying a direct incision after local anesthesia. Eventually, intraosseous hemangioma was diagnosed histologically. To fully resect the mass, the orbital floor and zygoma were exposed through a subciliary incision under general anesthesia, and then the tumor was completely eliminated. Bony defect was reconstructed by performing a seventh rib bone graft. Follow-up observation has so far been conducted for 10 months after surgery without recurrence or symptoms.

Infantile hemangiomas are the most common vascular tumors of infancy. A multidisciplinary approach including dermatologists, otolaryngologists, plastic surgeons, hematologists/oncologists and interventional/diagnostic radiologists is crucial for appropriate management of children with complicated infantile hemangiomas. Since its unforeseen discovery in 2008, propranolol has become the first-line treatment for infantile hemangiomas, eclipsing systemic corticosteroids and radiologic intervention. There are still, however, uncommon indications for more aggressive interventional management. We review the 2014-updated International Society for the Study of Vascular Anomalies (ISSVA) classification for vascular anomalies. Additionally, we suggest management algorithms for complicated lesions, including recommendations for radiologic and surgical intervention. (orig.)

Conclusion: Pyogenic granuloma is considered a reactive hyperproliferative vascular response to trauma or other stimuli. The name “pyogenic granuloma” is a misnomer since the condition is not associated with pus and does not represent a granuloma histologically. There are a few cases of lobular capillary hemangioma of the glans penis but it is rare on the female genitalia. We present this case to help physicians become aware that lobular capillary hemangiomas may occur at this site.

After an initial ultrasonographic examination, 5l hepatic hemangiomas in 4l patients were confirmed by one or combined examinations of 99mTc RBC SPECT, computed tomography, magnetic resonance imaging. angiography or ultrasonographic follow up. Definition of margin, internal echogenicity,peripheral rim and posterior enhancement were evaluated by two radiologists. Forty seven cases(92%) of 51 hemangiomas appeared to be well defined. Of 29 hemangiomas with less than 3cm in diameter. 25 cases (86%)showed homogeneous internal echogenicity. Of 22 hemangiomas with above 3 cm in diameter, 16 cases (73%) showed inhomogeneous echogenicity. Of 12 hemangiomas (24%) with peripheral rim, nine cases revealed hyperechoic rim and two hypoechoic rim. The remaining one case showed hyperechoic rim and hypoechoic rim alternately. Hemangiomas with greater than 3cm in diameter had higher incidence of inhomogeneous echogenicity, peripheral rim and posterior enhancement than those less than 3 cm(P<0.05). The majority of small hepatic hemangiomas are well defined homogeneous hyperechoic masses. On the other hand, large hemangiomas tended to have higher incidence of inhomogeneous internal echogenicity, posterior enhancement and a peripheral hyperechoic rim. A hyperechoic mass with a hypoechoic rim should also be considered as a candidate for hepatic hemangioma

Physical examination showed an ovoid, solid, 1 x 2 mm in size on the dorsum of penis (Panel A and two elevated irregular lesions on the ventral side (Panel B. The lesions were compressive, nonpulsatile and bluish-red in color with strawberry like appearance. Biopsy and histopathological examination of the lesion revealed a gaping and communicating vessels proliferated in the superficial and medium dermis which is pathognomonic for cavernous hemangioma (Panel C and D. Given the small size, the large number of the lesions, the young age, and the ulceration risk during intercourse if skin graft after excision, Neodymium: YAG laser coagulation was recommended to get a good cosmetic results and sexual function satisfaction.

Capillary hemangioma is the most common benign tumor of eyelids and orbit in children. Recently, a topical beta blocker has been reported as an effective treatment for superficial capillary hemangiomas. We present a case report of two children having large capillary hemangiomas who responded well to topical treatment by 0.5% timolol maleate solution. After 12 months of treatment, the lesion has significantly reduced in size, thickness, and color in both cases. Thus, we conclude that long-term use of topical 0.5% timolol maleate solution is safe and effective in treating superficial capillary hemangiomas.

Common infantile hemangiomas (COMMON) occur in approximately 10% of infants by the age of 1 year, with a female predominance. Some hemangiomas can be fully developed at birth and are thus called congenital hemangiomas (CH). Within this population, two courses have been identified: rapidly involuting CH (RICH) and non-involuting CH (NICH). Little has been reported on the clinical prognosis and imaging features of these entities. To describe the imaging characteristics of two subtypes of CH, i.e. RICH and NICH, and to compare them with COMMON. We retrospectively gathered data on 26 children presenting with CH, i.e. lesions fully developed at birth. These lesions were divided into two groups according to the clinical course: suspected RICH (n=8) and suspected NICH (n=18). We used US, CT or MRI and angiography to identify the gross anatomy and structure and the vascularization. Imaging findings were compared with the clinical course and pathology results, when available. The imaging findings in these patients were compared retrospectively with those in 26 patients with COMMON randomly chosen from the database of our multidisciplinary clinic. When compared with COMMON imaging characteristics, NICH and RICH had distinctive features on US such as being heterogeneous (72% of NICH and 62.5% of RICH vs 42.3% of COMMON), visible vessels (72% of NICH and 62.5% of RICH vs 15.4% of COMMON), calcifications (17% of NICH and 37.5% of RICH vs no case of COMMON). On CT and/or MRI, we compared imaging features such as well-defined limits (67% of NICH and 60% of RICH vs 100% of COMMON), and fat stranding (29.4% of NICH and RICH vs 7.7% of COMMON). Distinctive imaging characteristics are observed in cases of CH with US findings of visible vessels and calcifications statistically significant. (orig.)

Optical coherence tomography angiography (OCTA) allows visualization of iris racemose hemangioma course and its relation to the normal iris microvasculature. To describe OCTA features of iris racemose hemangioma. Descriptive, noncomparative case series at a tertiary referral center (Ocular Oncology Service of Wills Eye Hospital). Patients diagnosed with unilateral iris racemose hemangioma were included in the study. Features of iris racemose hemangioma on OCTA. Four eyes of 4 patients with unilateral iris racemose hemangioma were included in the study. Mean patient age was 50 years, all patients were white, and Snellen visual acuity was 20/20 in each case. All eyes had sectoral iris racemose hemangioma without associated iris or ciliary body solid tumor on clinical examination and ultrasound biomicroscopy. By anterior segment OCT, the racemose hemangioma was partially visualized in all cases. By OCTA, the hemangioma was clearly visualized as a uniform large-caliber vascular tortuous loop with intense flow characteristics superimposed over small-caliber radial iris vessels against a background of low-signal iris stroma. The vascular course on OCTA resembled a light bulb filament (filament sign), arising from the peripheral iris (base of light bulb) and forming a tortuous loop on reaching its peak (midfilament) near the pupil (n = 3) or midzonal iris (n = 1), before returning to the peripheral iris (base of light bulb). Intravenous fluorescein angiography performed in 1 eye depicted the iris hemangioma; however, small-caliber radial iris vessels were more distinct on OCTA than intravenous fluorescein angiography. Optical coherence tomography angiography is a noninvasive vascular imaging modality that clearly depicts the looping course of iris racemose hemangioma. Optical coherence tomography angiography depicted fine details of radial iris vessels, not distinct on intravenous fluorescein angiography.

We report the case of a 39-year-old woman with adolescent idiopathic scoliosis presenting with myelopathy secondary to a spinal epidural hemangioma. MRI showed an epidural soft tissue mass within the spinal canal between T5 and T9 with severe spinal cord compression. Symptoms had a temporal relationship to her pregnancy. Surgical removal of the epidural hemangioma rapidly relieved her symptoms and neurologic deficits. Follow-up examination 2 years later demonstrated normal motor and sensory function, without any neurologic sequelae or progression of deformity. (orig.)

Hemangiomas of the head or face are a frequent vascular pathology, consisting in an embryonic dysplasia that involves the cranial-facial vascular network. Hemangiomas show clinical, morphological, developmental, and structural changes during their course. Morphological, structural, ultrastructural, and clinical characteristics of head-facial hemangiomas were studied in 28 patients admitted in our hospital. Nineteen of these patients underwent surgery for the removal of the hemangiomas, whereas 9 patients were not operated on. All the removed tissues were transferred in our laboratories for the morphological staining. Light microscopy, transmission electron microscopy, and scanning electron microscopy techniques were used for the observation of all microanatomical details. All patients were studied for a clinical diagnosis, and many were subjected to surgical therapy. The morphological results revealed numerous microanatomical characteristics of the hemangiomatous vessels. The observation by light microscopy shows the afferent and the efferent vessels for every microhemangioma. All the layers of the arterial wall are uneven. The lumen of the arteriole is entirely used by a blood clot. The observation by transmission electron microscopy shows that it was impossible to see the limits of the different layers (endothelium, medial layer, and adventitia) in the whole wall of the vessels. Moreover, both the muscular and elastic components are disarranged and replaced with connective tissue. The observation by scanning electron microscopy shows that the corrosion cast of the hemangioma offers 3 periods of filling: initially with partial filling of the arteriolar and of the whole cast, intermediate with the entire filling of the whole cast (including arteriole and venule), and a last period with a partial emptying of the arteriolar and whole cast while the venule remains totally injected with resin. Our morphological results can be useful to clinicians for a precise

Full Text Available O controle da entrada de água de chuva no interior do aterro de resíduos sólidos urbanos durante sua construção e após seu fechamento é crucial para manter o controle da geração de lixiviado. Este fator pode contribuir para a elevação de gastos com tratamento e monitoramento e para a instabilidade mecânica do aterro. Por esta razão, o sistema de cobertura final de um aterro de resíduos sólidos urbanos é decisivo ao controle da entrada de água no mesmo. Na maioria dos casos, o sistema de cobertura final é composto por solo compactado. Frequentemente, um solo adequado para a cobertura não é encontrado nos arredores do aterro; portanto, recursos têm que ser despendidos para o transporte do mesmo até o devido local. Uma alternativa seria a utilização de uma barreira capilar construída com resíduos pré-tratados mecânica e biologicamente. No entanto, o uso deste material para esta construção ainda não foi bem estudado, e as diversas variáveis envolvidas no funcionamento de uma barreira capilar construída com resíduos sólidos pré-tratados mecânica e biologicamente são desconhecidas. O objetivo deste trabalho foi analisar os parâmetros envolvidos no funcionamento de uma barreira capilar construída exclusivamente de resíduos sólidos urbanos pré-tratados mecânica e biologicamente. Observou-se que este utilizado como material de uma barreira capilar pode funcionar de maneira equivalente àquela construída com solo, sendo boa a sua capacidade de retenção da água de chuva.

Full Text Available Context: Vascular anomalies present diagnostic challenges to histopathologists. Mulliken and Glowacki′s classification categorizes vascular lesions into hemangiomas and vascular malformations. Aim: This study explored diagnostic clues in the histomorphology of hemangiomas and vascular malformations. Materials and Methods: A total of 120 cases of benign vascular lesions were retrieved from 12 years period. A total of 94 cases, where complete clinical details and representative paraffin sections were available, were included in this study. Hematoxylin and eosin (H and E stain and Verhoeff′s stain for elastic tissue were done on all cases and lesions were classified into hemangiomas or arterio-venous malformations (AVM. Mast cell density in all lesions was calculated from toluidine blue stained sections. Results: Ten cases of hemangiomas were reclassified as AVM on the basis of presence and absence of arteriovenous structures. Intra-lesional nerves were seen in significantly higher number of AVMs compared to hemangiomas. Medium and thick sized nerve bundles were seen in 56% of AVMs, while they were not seen in any of the hemangiomas. Mean mast cell density was significantly higher in proliferating hemangiomas (53.12 ± 27.83 cells/mm 2 compared to involuting hemangiomas (11.43 ± 7.9 cells/mm 2 . Conclusions: Use of elastic tissue stains are useful ancillary tools to distinguish between AVMs and hemangiomas. The presence of arteries and arterioles are an integral part of AVMs. The presence of the intra-lesional nerves can be useful to distinguish between AVMs and hemangiomas even on H and E stained sections. The significantly higher mast cell density seen in proliferating hemangiomas compared with involuting ones, seem to suggest that mast cells play an important role in the natural history of these lesions.

To evaluate the differences in sonographic appearance and hemodynamics between hypoechoic and hyperechoic hemangioma Material and Method : We retrospectively reviewed the sonographic appearance and MRI findings of 23 hypoechoic hepatic hemangiomas in 16 consecutive patients. Nine were men and seven were women, witha mean age of 50 years(range, 40-72). We analyzed the sonographic appearance such as size, shape, border,echogenecity, posterior acoustic enhancement and the presence of fatty liver, and MRI findings such as signal intensity, enhancement pattern. For comparison, we also reviewed the sonographic appearance and MRI findings of 23 hyperechoic hemangiomas in 16 randomly selected patients. Results : There were no differences in size, shape,incidence of posterior acoustic enhancement, MR signal intensity or enhancement pattern between hypoechoic and hyperechoic hemangiomas(p>0.05, Chi-square). However, fatty infiltration of the liver and echogenic rim of the masses were more commonly seen in hypoechoic hemangiomas(9:1, 5:0, respectively, p<0.05). Conclusions : There we reno differences in MR enhomcement pattern or incidence of posterior acoustic enhancement between hypoechoic hyperechoic hemangioma. The vascularity of a mass therefore seems to contribute little to its echogenecity

To determine the incidence of hepatic hemangiomas associated with wedge-shaped parenchymal enhancements adjacent to the tumors as seen on two-phase spiral CT images obtained during the hepatic arterial phase and to characterize the two-phase spiral CT findings of those hemangiomas. One hundred and eight consecutive hepatic hemangiomas in 63 patients who underwent two-phase spiral CT scanning during an 11-month period were included in this study. Two-phase spiral CT scans were obtained during the hepatic arterial phase (30-second delay) and portal venous phase (65-second delay) after injection of 120 mL of contrast material at a rate of 3 mL/sec. We evaluated the frequency with which wedge-shaped parenchymal enhancement was adjacent to the hemangiomas during the hepatic arterial phase and divided hemangiomas into two groups according to whether or not wedge-shaped parenchymal enhancement was noted (Group A and Group B). The presence of such enhancement in hemangiomas was correlated with tumor size and the grade of intratumoral enhancement. In 24 of 108 hemangiomas, wedge-shaped parenchymal enhancement adjacent to hepatic tumors was seen on two-phase CT images obtained during the hepatic arterial phase. Mean hemangioma size was 22mm in group A and 24mm in group B. There was no statistically significant relationship between lesion size and the presence of wedge-shaped parenchymal enhancement adjacent to a hemangioma. In 91.7% and 100% of tumors in Group A, and in 9.6% and 17.8% in Group B, hemangiomas showed more than 50% intratumoral enhancement during the arterial and portal venous phase, respectively. Wedge-shaped parenchymal enhancements peripheral to hepatic hemangiomas was more frequently found in tumors showing more than 50% intratumoral enhancement during these two phases (p less than 0.01). Wedge-shaped parenchymal enhancements is not uncommonly seen adjacent to hepatic hemangiomas on two-phase spiral CT images obtained during the hepatic arterial phase. A

An incidental ovarian mass: A case of ovarian hemangioma with prominent stromal luteinization

Directory of Open Access Journals (Sweden)

Babak Shirazi

2015-01-01

Full Text Available Ovarian hemangioma is a rare benign tumor of female genital tract. Stromal luteinization in ovarian hemangioma is an uncommon process and the pathogenesis is controversial. In this regard, two hypotheses have been suggested whether luteinization is a reactive process or it is the stimulator for development of ovarian hemangioma. Here, we report a case of a 55-year-old woman who referred to our center due to incidental finding of left ovarian mass in pelvic sonography. Microscopically, the mass showed a mixed cavernous and capillary hemangioma and the peripheral stroma contained several small and large clusters of stromal cells, which were luteinized. It should be noted that an ovarian hemangioma could be associated with stromal luteinization although its pathogenesis is not clearly known. Yet, we believe the stromal luteinization around ovarian hemangioma could be a reactive phenomenon.

Infantile hemangiomas demonstrate a pattern of proliferative growth in infancy followed by a slow phase of involution. In contrast a rare type of vascular tumor, intramuscular capillary-type hemangioma, usually presents beyond the period of infancy with nonspecific symptoms and no evidence of involution. The purpose of this study was to characterize the clinical, imaging, histopathological characteristics and management of intramuscular capillary-type hemangioma. We performed a retrospective review of a 20-year period to identify children diagnosed with intramuscular capillary-type hemangioma. Patient demographics, imaging and histopathological findings were recorded. We included 18 children (10 boys, 8 girls) with histologically proven intramuscular capillary-type hemangioma - and adequate imaging. The mean age at presentation was 8.1 years (range 1 day to 19 years). Twelve lesions involved muscles of the extremities, 4 were located in the trunk and 2 were in the head and neck. MRI had been performed in all children and demonstrated a soft-tissue mass with flow voids, consistent with fast flow. The lesion was well-circumscribed in 16 children and intralesional fat was seen in 14. Doppler US demonstrated a heterogeneous lesion, predominantly isoechoic to surrounding muscle, with enlarged arterial feeders. Enlarged feeding arteries, inhomogeneous blush and lack of arteriovenous shunting were noted on angiography (n = 5). The most common histopathological findings were lobules of capillaries with plump endothelium and at least some adipose tissue. The lesions were excised in six children. Two children were lost to follow-up. In the remaining 10, follow-up MRI studies ranging from 3 months to 10 years showed that the lesion enlarged in proportion to the child (n = 7), demonstrated slow growth (n = 2) or remained stable (n = 1). There was no change in imaging characteristics on follow-up. Intramuscular capillary-type hemangioma is a rare benign vascular tumor of

Evaluation and management of Periocular Capillary Hemangioma: A review

To review the salient features of periocular capillary hemangioma, provide the ophthalmologist with clinical, diagnostic and histological features characteristic of the tumor and discuss various methods of management. Methods were literature review of periocular capillary hemangioma, diagnostic evaluation with emphasis on treatment through the presentation of illustrative clinical cases. Capillary hemangioma is the most common benign vascular tumor found on the head and neck area including eyelids and orbit. The lesion typically manifests within the first few weeks of life, grows rapidly in the first year during the proliferative phase, then invariably and slowly regresses over the next 4 to 5 years during the involutional phase. The lesion may resolve without leaving any significant cosmetic sequelae in vast majority of patients, however, the functional defects in the form of amblyopia, squint, facial disfigurement and rarely optic atrophy may persist long after complete resolution of the tumor. The diagnosis of the capillary hemangioma requires a combination of clinical and imaging studies such as ultrasonography, computerized tomography, magnetic resonance imaging and angiography in selected cases. With the advent of less invasive diagnostic techniques, the need for biopsy in capillary hemangioma has decreased. Nevertheless, it should be differentiated from other periocular tumors such as rhabdomyosarcoma, lymphangioma, chloroma, neuroblastoma, orbital cyst, and orbital cellulites. Treatment is indicated to prevent amblyopia or cosmetic disfigurement. If indicated, intra-lesional corticosteroids may be used to enhance resolution of the tumor. Other forms of treatment tried with variable success include systematic and topical corticosteroids, radiation, surgical excision and intravenous embolization of the tumor. Indecent years, laser ablation of the tumor has been found effective in some cases. Interferon-u has been utilized effectively in cases of capillary

The synovial hemangioma is an uncommon benign vascular tumor that is difficult to diagnose on the basis of clinical signs Moreover, it has no characteristic radiographic features. The objective of the present report was to describe the MR findings associated with synovial hemangioma of the knee. We review the clinical and MR findings in six patients, with histologically confirmed synovial hemangioma of the Knee, studied with different MR systems and techniques. Synovial hemangiomas were isointense with respect to muscle in T1-weighted images, strongly hyperintense in T2-weighted sequences and presented wavy hypointense linear images. Gadolinium administration resulted in a marked enhancement, although it was heterogeneous in two of three cases analyzed. Although the findings are not pathognomonic, the presence of an intraarticular tumor of the knee that is isointense with respect to muscle in T1 and hyperintense in T2, and shows wavy hypointense images and a marked contrast uptake, may suggest the presence of synovial hemangioma.

Intracerebral capillary hemangiomas are very rare benign vascular tumors that mostly occur during infancy. We described a 69-year-old man with generalized tonic-clonic seizures who was diagnosed with an intracranial mass. Multidetector computed tomography, magnetic resonance imaging and digital subtraction angiography studies were performed for evaluation of brain, and there was a well-enhancing mass found in the right temporal lobe without a definite feeding vessel. The patient underwent surgery and the pathologic examination demonstrated marked proliferation of small vessels with a lobular pattern in the brain parenchyma, which was confirmed to be capillary hemangioma.

2009-11-01

Pulmonary sclerosing hemangioma (PSH) is an uncommon benign tumor that presents as a solitary asymptomatic and slow-growing nodule. It occurs in both young and old persons; peak incidence is in the fifth decade. Both sexes are affected by this tumor, but women more frequently than men. On histological examination, PSH shows prominent sclerotization and vascularization of the tissue. Recent studies conclude that PSH derives from type II pneumocytes, but the potential for progression and histogenesis remains controversial. We report a case of pulmonary sclerosing hemangioma in a 61-year-old woman with a neoplastic node 1 cm in diameter. The karyotype was 46,XX,t(8;18),der(14;15),+14 in all the cells analyzed. PTEN (10q23) and IgH (14q32) probes were analyzed in interphase nuclei and paraffin-embedded tissues of tumor cells. These chromosome abnormalities could provide information about the relationship of genetic changes to the biological properties of sclerosing hemangioma tumors.

Full Text Available Objective: Hemangiomas of infancy are the most common benign tumours of childhood. Cryotherapy is a widely accepted modality for the treatment of hemangiomas of the newborn. However, no studies clearly supporting its effectivity are available. In contrast to an earlier "wait and see" approach to treating hemangiomas in young children, we sought to determine whether these vascular lesions would respond to contact cryosurgery.Methods: Nineteen patients with 25 infantil hemangiomas were included in the study between 2003-2008 years. Patients were treated with contact cryotherapy. All lesions were treated with the same method (double freeze-thaw cycle of 15 seconds.Results: In 15 lesion; 11 (%73.3 lesions healed with full regression, two (%13.3 lesions healed with partially regression, one lession showed no change and one lesion showed progression. Conclusion: Contact cryotherapy has been evaluated as an effective and safe method in infantil hemangiomas.

Retinal cavernous hemangioma is a rare, benign, retinal tumor characterized by angiomatous proliferation of vessels within the inner retina or the optic disc.1 Here we report a case of retinal cavernous hemangioma on the margin of the optic disc in the right eye of a 61-year-old asymptomatic female. The lesion was studied with multimodal imaging which included structural optical coherence tomography, fluorescein angiography, blue fundus auto-fluorescence, optical coherence tomography angiography (OCTA) (DRI OCT Triton; Topcon, Tokyo, Japan) and visual field examination. Blood circulation inside retinal cavernous hemangioma lesion is typically low-stagnant.2 However, OCTA demonstrated blood flow inside the lesion, illustrating its vascular circulation.3 Visual field was within the normal limits, except from a slight enlargement of the blind spot.

To compare computed tomography (CT) and magnetic resonance imaging (MRI) findings between two histological types of nasal hemangiomas (cavernous hemangioma and capillary or lobular capillary hemangioma). CT (n = 20; six pre-contrast; 20 post-enhancement) and MRI (n = 7) images from 23 patients (16 men and seven women; mean age, 43 years; range, 13-73 years) with a pathologically diagnosed nasal cavity hemangioma (17 capillary and lobular capillary hemangiomas and six cavernous hemangiomas) were reviewed, focusing on lesion location, size, origin, contour, enhancement pattern, attenuation or signal intensity (SI), and bony changes. The 17 capillary and lobular hemangiomas averaged 13 mm (range, 4-37 mm) in size, and most (n = 13) were round. Fourteen capillary hemangiomas had marked or moderate early phase enhancement on CT, which dissipated during the delayed phase. Four capillary hemangiomas on MRI showed marked enhancement. Bony changes were usually not seen on CT or MRI (seen on five cases, 29.4%). Half of the lesions (2/4) had low SI on T1-weighted MRI images and heterogeneously high SI with signal voids on T2-weighted images. The six cavernous hemangiomas were larger than the capillary type (mean, 20.5 mm; range, 10-39 mm) and most had lobulating contours (n = 4), with characteristic enhancement patterns (three centripetal and three multifocal nodular), bony remodeling (n = 4, 66.7%), and mild to moderate heterogeneous enhancement during the early and delayed phases. CT and MRI findings are different between the two histological types of nasal hemangiomas, particularly in the enhancement pattern and size, which can assist in preoperative diagnosis and planning of surgical tumor excision.

Full Text Available The paper describes a clinical case of testicular capillary hemangioma in a 24-year-old man undergone a partial resection of the testis with the intraoperative morphological examination. Testicular capillary hemangioma is a rare benign tumor of a vascular origin, which can be similar to malignant testicular tumors on the clinical presentation, as well as on the imaging methods, in particular to seminoma. The intraoperative histological study can assist in avoiding organ-removing surgical interventions in diagnostically ambiguous cases if a benign testicular tumor is diagnosed.

Preliminary Report On Combined Surgical- And Laser-Treatment Of Large Hemangiomas And Tattoos

Science.gov (United States)

Ginsbach, G.

1981-05-01

As most hemangiomas and tattoos require many sessions to be cured completely by argon-laser or conventional therapy I developed a new combined surgical and laser-therapy method for large hemangiomas and tattoos. This is a three step method. First: The skin lesion is treated by argon-laser with the point by point method, developed by ourself. Second: Under local or general anaesthesia a) the hemangioma is partially excised and undermined letting only the skin which is already treated by argon-laser-beams. Than the hemangioma is exstirpated in toto, the wound closed by running intradermal sutures and a pressure bandage applied, b) the tattoo is abraded as deep as possible, draped by lyofoam. Then a pressure bandage is applied. Third: The hemangioma as well as the tattoo are treated by argon-laser-beams after the operation. This method is safe and effective, gives good results, minimal scars in the case of hemangiomas and tattoos. In this paper the method is described and some cases are illustrated by pre- and postoperational photographs.

Full Text Available Abstract Hemangiomas of the median nerve are very rare and, so far, only ten cases of intraneural hemangioma of this nerve have been reported in the literature. We present a case of 14-year-old girl who had a soft tissue mass in the region of the left wrist with signs and symptoms of carpal tunnel syndrome. Total removal of the mass was achieved using microsurgical epineural and interfasicular dissection. The symptoms were relieved completely, after this procedure, without any neurologic deficit. On follow-up two years later, no recurrence was observed. Whenever a child or young adult patient presents with CTS the possibility of a hemangioma involving the median nerve should be kept in mind in the differential diagnosis.

Objective: To explore the therapeutic method of treating infant hemangioma by radioisotopes 32 P. Methods: Simple hemangiomata were treated by 32 P dermal application method. The authors prepared 32 P at the activity of 165.98 kBq/cm 2 /h, diluted it with 2 ml water, and then dropped it on filter paper. The authors applied the paper to the impaired site according to the shape and the size of hemangioma. The impaired site received 32 P radiation at the dosage of 9.41 Gy/cm 2 each time. The treatment was repeated once every month. Cavernous hemangiomata were treated by local injections of colloid 32 P at the dosage of 370 kBq/cm 3 once every 2-3 months. Mixed hemangiomata received combined treatment mentioned above. Results: 3383 cases (99.0%) of simple hemangioma were cured by 32 P dermal application method. 1241 case (98.7%) of cavernous hemangioma were cured. 397 cases (83.0%) of mixed hemangioma were cured. 534 cases (98.1%) of naevus flammeus were improved by 32 P application method. The total effective rate was 99.8%. The cure rate was 88.3%. Conclusion: Treating hemangioma with 32 P is satisfactory for its high efficiency and low toxicity. It may be advisable for infant skin disease

5 cases are analysed of perinatal hemangiomas in internal localizations representing relative or immediate emergencies. Three cases were subglottic proliferating hemangiomas with threatening suffocation, the other two were large hemangiomas of the liver causing significant hepatomegaly. In 3 children there were also hemangiomas of the skin and or in the oral cavity seen as important signs in the diagnostic reflections on the nature of the urgent clinical pictures. Moreover one child with subglottic hemangioma suffered from hematological disorders characterizing the Kasabach-Merritt syndrome. In all the children transcutaneous radiotherapy was performed (ranging from 12 Gy in two weeks up to an exceptional dose of 25 Gy over 3 months). This resulted in recession of subjective complaints and, eventually, in complete regression of the irradiated angiomatous lesions, both subglottic and hepatic. The disorders of hemocoagulation also disappeared quickly and completely. At present, i.e., after 3 to 21 years, there are no adverse post-irradiation changes in any of the patients. Nevertheless, in view of possible post-irradiation effects particularly on the thyroid gland, all the patients continue to be regularly followed up at the respective clinical departments.

Hemangiomas are tumors. Hemangiomas near the geniculate ganglion or in the internal acoustic meatus are well known but rare. We present two cases of hemangiomas located at the porus acusticus, an even more rare site. MRI showed a millimeter-sized tumor, located in the porus acusticus, developing perpendicular to the axis of the acoustico-facial nerves, surrounding them. They were hyperintense on T1-weighted images, strongly hyperintense on T2-weighted images with a characteristic progressive and marked enhancement after injection of gadolinium DTPA. Similar signal abnormalities were present in the adjacent temporal bone, and CT scan demonstrated a honeycomb appearance with intra-tumoral bony spicules. These imaging criteria allows differentiation between hemangioma and neurinoma. We hypothesize that this location is related to the presence of a rich vascular plexus of the dura mater in this area.

Objective: To discuss the clinical value of preoperative magnetic resonance imaging examination in guiding the treatment of vertebral hemangiomas with percutaneous vertebroplasty (PVP). Methods: A total of 286 patients with vertebral hemangiomas detected on spine MRI in authors' Department were enrolled in this study. The patient's age, the lesion's size and location, the clinical symptoms, MRI findings, etc. were retrospectively analyzed. Results: A total of 336 vertebral bodies were affected in 286 patients. The lesions were mainly located at the lumbar spine (43.15%) and the thoracic spine (37.80%). The highest incidence of disease was seen in 50-59 years old patients (34.62%). The mean diameter of the lesions was 14.56 mm. Solitary lesion was seen in 85.66% of patients, while two vertebral bodies involved were seen in 10.14% of patients. Twelve cases (4.20%) simply presented as back pain at the related vertebral bodies. Two patients showed signs due to spinal cord compression. All aggressive vertebral hemangiomas were manifested as iso-lower signal on T1-weighted images and higher signal on T2-weighted images. Simple PVP was performed in 4 cases, and subtotal tumor excision together with PVP was carried out in two patients with aggressive vertebral hemangiomas. Conclusion: Evaluation of vertebral hemangiomas with MRI performed prior to percutaneous vertebroplasty is very helpful in guiding the selection of therapeutic scheme. (authors)

Infantile hemangioma: pulsed dye laser versus surgical therapy

Hemangioma is a mesenchymal benign tumor formed by blood vessels. Anomalies affect up to 10% of children and they are more common in females than in males. The aim of our study was to compare the treatment efficacy, namely the curative effect and adverse events, such as loss of pigment and appearance of scarring, between classical surgery techniques and laser techniques. For that reason a group of 223 patients with hemangioma was retrospectively reviewed. For treatment, a pulsed dye laser (PDL) (Rhodamine G, wavelength 595 nm, pulsewidth between 0.45 and 40 ms, spot diameter 7 mm, energy density 9-11 J cm-2) was used and the results were compared with a control group treated with classical surgical therapy under general anesthesia. The curative effects, mainly number of sessions, appearance of scars, loss of pigment, and relapses were evaluated as a marker of successful treatment. From the results it was evident that the therapeutic effects of both systems are similar. The PDL was successful in all cases. The surgery patients had four relapses. Classical surgery is directly connected with the presence of scars, but the system is safe for larger hemangiomas. It was confirmed that the PDL had the optimal curative effect without scars for small lesions (approximately 10 mm). Surgical treatment under general anesthesia is better for large hemangiomas; the disadvantage is the presence of scars.

Given the high prevalence of hepatic hemangioma, diagnostic techniques that differentiate these benign lesions from metastasis, hepatoma, and other malignant diseases are necessary. Twenty-five consecutive patients in whom ultrasonography led to the suspicion of hemangioma were studied by magnetic resonance (MR) and tomographic scintigraphy using 99m Tc-labeled red blood cells. Twenty patients presented 42 hemangiomas. Of the 5 remaining patients, 2 proved to have hepatoma and 3 had metastases. Both MR and SPECT have been shown to be highly sensitive in the diagnosis of hepatic hemangioma (95% and 74%, respectively). The specificity of both techniques was 100%. A diagnostic algorithm is presented, based on the high sensitivity and specificity of the two techniques for the purpose of avoiding unnecessary diagnostic measures. (Author)

Full Text Available Abstract Lower gastrointestinal hemorrhage accounts for approximately 20% of gastrointestinal hemorrhage. The most common causes of lower gastrointestinal hemorrhage in adults are diverticular disease, inflammatory bowel disease, benign anorectal diseases, intestinal neoplasias, coagulopathies and arterio-venous malformations. Hemangiomas of gastrointestinal tract are rare. Mesenteric hemangiomas are also extremely rare. We present a 25-year-old female who was admitted to the emergency room with recurrent lower gastrointestinal bleeding. An intraluminal bleeding mass inside the small intestinal segment was detected during explorative laparotomy as the cause of the recurrent lower gastrointestinal bleeding. After partial resection of small bowel segment, the histopathologic examination revealed a cavernous hemagioma of mesenteric origin. Although rare, gastrointestinal hemangioma should be thought in differential diagnosis as a cause of recurrent lower gastrointestinal bleeding.

We have observed that some children with facial hemangiomas of infancy have feeding difficulties coincident with periods of failure to thrive. We evaluated the early oral sensory and feeding experiences of four children with facial hemangiomas through medical record review and parental surveys to investigate their contribution to the patients' failure to thrive. All children with feeding irregularities experienced some degree of oral sensory impairment and required early oral sensory intervention, but there were varying reports of difficulty or delay in the development of oral feeding. The nature of these difficulties is discussed. Infants with complicated facial hemangiomas with perioral and airway involvement may be at higher risk for feeding and oral sensory problems. We recommend close monitoring for failure to thrive and early evaluation by speech or occupational therapists. © 2011 Wiley Periodicals, Inc.

Skeletal muscle hemangiomas are relatively uncommon tumors in children and young adults. Although the operative management of these lesions may be affected by their vascularity, the correct preoperative diagnosis is often not made. Ossification of these lesions is rare. Two patients are described whose skeletal muscle hemangiomas contained abundant osseous tissue. This was radiologically reflected by the 'swiss cheese' appearance of the tumors. Such an appearance in an ossified soft tissue mass may allow the correct preoperative diagnosis of this condition.

We present a young asymptomatic woman with splenomegaly and a large isolated splenic mass demonstrated by ultrasonography, 99m Tc sulfur colloid, and gallium scintigraphy studies. Computerized tomography (CT) and three-phase 99mTc-labeled red blood cell imaging suggested a malignant lesion. Repeated sonographically guided fine needle aspiration (FNA) obtained only blood, suggesting the possible vascular nature of the tumor. Splenectomy established the diagnosis of splenic hemangioma (SH) with marked sclerotic changes. We conclude from this case that (1) the sclerotic and cystic changes in the SH and the abdominal lymphadenopathy could explain why the three-phase red blood cell and CT scanning, respectively, suggested that the lesion was malignant rather than benign; (2) guided FNA of a splenic mass suspected to be hemangioma may be an additional safe and useful diagnostic procedure. Multiple aspirations yielding blood alone suggest hemangioma and may prevent an unnecessary operation. To the best of our knowledge, this is the first reported case in the literature of FNA of splenic hemangioma

Hepatic hemangiomas as diagnosed by ultrasonography and computed tomography

1987-01-01

A total of 62 cases where the clinical diagnosis of hepatic hemangioma had been established during the period between 1981 and 1983 on the basis of computed tomography and sonography were subjected to retrospective analysis with the aim of evaluating the diagnostic reliability of these two methods. In 29 patients a typical distribution pattern of the contrast medium gave irrefutable evidence of the disease. Hemangiomas were predicted from the results of computed tomography for a further 5 patients with less revealing distribution patterns, although in 4 among these the preliminary diagnosis of hemangioma was disproved by additional diagnostic procedures (scintigraphy, laparoscopy, surgery and biopsy). Out of 16 patients, in which the hemangiomas were diagnosed from the typical patterns created by the contrast medium on the CT scans, 11 showed sonographic findings to confirm the presence of such tumours. This retrospective analysis showed that a correct and positive diagnosis could be established in no more than 7 patients on the basis of sonography alone, while 6 such diagnoses were definitely proven to be false-positive. As regards diagnostic accuracy, sonography clearly compares unfavourably with computed tomography. It may offer some advantages inasmuch as it requires no radiation exposure, is non-invasive and, last not least, less costly. (ECB) [de

Full Text Available Introduction. Adrenal hemangioma is a rare disease, with only some 60 cases reported previously. Due to the difficulty of the preoperative diagnosis of adrenal hemangioma, almost all of the cases were diagnosed by a histopathological analysis of surgical specimens. Case Presentation. A 52-year-old man was referred to our department for further examination of his left retroperitoneal tumor. He had received hemodialysis due to chronic renal failure resulting from membranous nephropathy. Computed tomography revealed a mass around his left hilum. Magnetic resonance imaging (MRI and positron-emission tomography (PET-CT were unable to confirm or deny malignancy, and tumor markers, including CEA and CA19-9, showed slight elevation. His tumor grew from 38 mm to 54 mm in diameter in 7 months of follow-up. We therefore planned retroperitoneal tumor resection with left nephrectomy. Histopathologically, hyperplastic small vessels with hemorrhaging and denaturation were seen. The endothelial cells showed no variants or division of the nucleus. Based on this diagnosis, no further therapy was performed. He has had no recurrence in the eight months since the surgery. Conclusion. We herein report a rare case of adrenal hemangioma.

The release profile of propranolol from PLIM was evaluated, and its biological activity was investigated in vitro using proliferation assays on hemangioma stem cells (HemSCs. Tumor inhibition was studied in nude mice bearing human subcutaneous infantile hemangioma.Results: The microspheres were of desired particle size (~77.8 µm and drug encapsulation efficiency (~23.9% and achieved sustained drug release for 40 days. PLIM exerted efficient inhibition of the proliferation of HemSCs and significantly reduced the expression of two angiogenesis factors (vascular endothelial growth factor-A [VEGF-A] and basic fibroblast growth factor [bFGF] in HemSCs. Notably, the therapeutic effect of PLIM in hemangioma was superior to that of propranolol and PL in vivo, as reflected by significantly reduced hemangioma volume, weight, and microvessel density. The mean hemangioma weight of the PLIM-treated group was significantly lower than that of other groups (saline =0.28 g, propranolol =0.21 g, PL =0.13 g, PLIM =0.03 g; PLIM vs saline: P<0.001, PLIM vs propranolol: P<0.001, PLIM vs PL: P<0.001.

Full Text Available Hemangiomas are the most common benign tumors of childhood. They show rapid growth, followed by a regression phase that culminates in the partial or total disappearance of the lesion. Therapeutic options should be evaluated for extensive cases. Systemic glucocorticoids are the therapy of choice; however, there are reports that propranolol offers better and faster results. We report two cases of large volume infantile hemangioma associated with functional limitation and aesthetic disfigurement, treated successfully with propranolol, a drug that comes as a therapeutic option providing satisfactory and maintained results, with few side effects.Hemangiomas são os tumores benignos mais frequentes da infância, apresentando como história natural crescimento rápido, seguido de uma fase de regressão que culmina com o desaparecimento parcial ou total da lesão. Opções terapêuticas devem ser avaliadas para casos extensos. Os glicocorticoides sistêmicos são a terapia de escolha; contudo, há relatos de que o propranolol oferece resultados melhores e mais rápidos. Este trabalho descreve dois casos de hemangioma infantil de grande volume associados à limitação funcional e desfiguração estética com significativa resposta ao propranolol, droga esta que surge como uma proposta terapêutica oferecendo resultados satisfatórios e mantidos, com poucos efeitos colaterais.

Methods: This is a retrospective chart review of clinically diagnosed capillary hemangioma cases involving the periocular region treated at two local eye institutions. The patients' demographics and clinical presentation – including visual acuity, refractive error, periorbital and orbital examinations, and ultrasound and magnetic resonance imaging findings – were reviewed. The clinical progression, modalities of treatment, and treatment outcomes were studied. Results: Sixteen cases of capillary hemangiomas involving the eyelid and orbit were studied. The mean age at consultation was 9.6 months (range: 1 month–72 months. The majority were females (75%, with 50% presenting as upper-eyelid hemangiomas and the remaining as lower-eyelid (38% and glabellar (12% lesions. Combined superficial and deep involvement was common (64%. Cases whose lesions were located at the upper eyelid or superior orbit led to amblyopia (25%. Fifty-six percent of cases (9/16 were managed conservatively, and 44% (7/16 underwent treatment with either single-agent (n = 4 or combined treatments (n = 3. Conclusion: Close monitoring of visual development and prompt institution of amblyopia therapy for children with periocular capillary hemangiomas generally preserve vision.

The common benign tumor of the liver, cavernous hemangioma, has already been confirmed, both embryologically and pathologically, to be not a neoplasm, but a congenital vascular malformation of the liver which is resulted from the arrested development of hepatic sinusoids at embryologic stage. This paper aims to make a comprehensive description of the cavernous hemangiomas of the liver, including the lesion's blood supply, the hemodynamics, the imaging features, the classification and its interventional therapy. The relevant example illustrations, figures and graphics are accompanied with the text in order to provide the readers with an complete and up-to-date understanding of the hepatic cavernous hemangiomas.

Full Text Available Relato de um caso de astrocitoma grau II com metástase medular ao nível da terceira vértebra dorsal. O nódulo intradural determinou sinais e sintomas de compressão medular. O diagnóstico clínico foi confirmado por mielografia descendente com lipiodol e mielocintilografia com I131 - albumina. A paciente foi submetida a laminectomia para exerese da metástase. A revisão da literatura mostra que o fator mais importante para a ocorrência das metástase dos tumores encefálicos é a invasão do sistema ventricular e/ou espaço subaracnóideo periencefálico pela neoplasia, sem relação com o ato operatório.

Hemangioma of the prostate - an unusual cause of lower urinary tract symptoms: Case report

Full Text Available Abstract Background Hemangioma of the prostate gland is extremely rare and only a few cases have been reported. There have been several cases of hemangioma of posterior urethra, urinary bladder and periprostatic plexus in the literature, all presenting with hematuria or hematospermia. Diagnosis of prostatic hemangioma is difficult due to its rarity and unspecific symptoms such as hematuria, hematospermia or lower urinary tract symptoms. It cannot be detected by conventional examinations such as cystoscopy or standard rectal ultrasonography. Case presentation We present a case of prostatic hemangioma in an 84-year old male presenting with lower urinary tract symptoms. Bleeding has not been a feature in our case and diagnosis was not made until after operation. The patient was treated as a case of bladder neck outflow obstruction with transurethral resection of prostate gland and simultaneous bladder neck incisions. A period of self-catheterization was instituted due to postoperative urinary retention as the result of detrusor insufficiency. Conclusion Hemangioma of prostate gland is extremely rare and symptomatic prostatic hemangioma should be treated either by transurethral resection of prostate or laser evaporation.

To define the clinical spectrum of regional congenital anomalies associated with large cutaneous hemangiomas of the lower half of the body, clarify risk for underlying anomalies on the basis of hemangioma location, and provide imaging guidelines for evaluation. We conducted a multi-institutional, retrospective case analysis of 24 new patients and review of 29 published cases. Hemangiomas in our series tended to be "segmental" and often "minimal growth" in morphology. Such lesions were often extensive, covering the entire leg. Extensive limb hemangiomas also showed potential for extracutaneous anomalies, including underlying arterial anomalies, limb underdevelopment, and ulceration. The cutaneous hemangioma and underlying anomalies demonstrated regional correlation. Myelopathies were the most common category of associated anomalies. We propose the acronym "LUMBAR" to describe the association of Lower body hemangioma and other cutaneous defects, Urogenital anomalies, Ulceration, Myelopathy, Bony deformities, Anorectal malformations, Arterial anomalies, and Renal anomalies. There are many similarities between LUMBAR and PHACE syndrome, which might be considered regional variations of the same. Although guidelines for imaging are suggested, prospective studies will lead to precise imaging recommendations and help determine true incidence, risk and long-term outcomes.

Hemangiomas are rarely found in the heart and pericardial involvement is even more rare. We report a case of primary pericardial hemangioma, in which three-dimensional transesophageal echocardiography (3DTEE) provided incremental benefit over standard two-dimensional images. Our case also highlights the importance of systematic cropping of the 3D datasets in making a diagnosis of pericardial hemangioma with a greater degree of certainty. In addition, we also provide a literature review of the features of cardiac/pericardial hemangiomas in a tabular form. © 2017, Wiley Periodicals, Inc.

Large capillary hemangioma of the temporal bone with a dural tail sign: A case report

KAUST Repository

YANG, GUANG

2014-05-13

The present study reports a rare case of large capillary hemangioma of the temporal bone with a dural tail sign. A 57-year-old female presented with pulsatile tinnitus and episodic vertigo associated with a ten-year history of an intermittent faint headache. Magnetic resonance imaging revealed a mass in the right petrous bone, which was hypointense on T1-weighted images and heterogeneously hyperintense on T2-weighted images, and showed a dural tail sign following gadolinium administration. Pre-operatively, this tumor was believed to be a meningioma. During surgery, the vascular tumor was removed by a modified pterional approach. A histopathological examination indicated that the tumor was a capillary hemangioma. Although intraosseous capillary hemangiomas are rare, they most frequently affect the temporal bone. Hemangiomas of the temporal bone may mimic other more common basal tumors. The diagnosis is most often made during surgical resection. The dural tail sign is not specific for meningioma, as it also occurs in other intracranial or extracranial tumors. The treatment of intratemporal hemangiomas is complete surgical excision, with radiotherapy used for unresectable lesions. To the best of our knowledge, the present study is the fourth case of intraosseous intracranial capillary hemangioma, but the largest intratemporal hemangioma to be reported in the literature to date.

Infantile hemangiomas are well known for their rapid growth during the first 6 to 9 months of life, followed by a spontaneous but slow involution. The standard of care is to treat these lesions at an early age with propranolol to expedite the involution process; however, surgery still remains an active component in the management. Medical treatment with propranolol or natural involution will often result in residual telangiectasias. We evaluated the efficacy of using a diode laser as a treatment for telangiectasias following cervicofacial infantile hemangioma involution. Case series with chart review. Tertiary care hospital and practice specializing in the care of vascular anomalies. Twenty patients, aged 4 months to 11 years (average 2.69 years), underwent treatment with a 532-nm diode laser to treat the residual telangiectasias following hemangioma involution. All procedures were performed in the operating room. To assess the efficacy, we independently evaluated pre- and posttreatment digital photographs and ranked them on a 0- to 4-point scale (0 = no change and 4 = complete response). Adverse reactions were also recorded. The telangiectasias showed considerable improvement following treatment. In more than half of the patients treated, the affected area demonstrated a complete response. No adverse reactions were noted. A 532-nm diode laser effectively treats the remaining telangiectasias following hemangioma involution. Whether used independently or in conjunction with other treatment modalities, the diode laser should be part of the surgical armamentarium when treating infantile hemangiomas. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

To report on the differential diagnosis of lyme arthritis and synovial hemangioma due to similar clinical and radiological signs and symptoms. A 15-year-old boy presented at the age of 9 with recurrent rather painless swelling of the right knee. Altogether four episodes lasting for 1-2 weeks each occurred over a period of 18 months before medical advice was sought. Physical examination revealed only a slightly limited range of motion. Living in an endemic area of borreliosis, he reported a tick bite 6 months prior to onset of his symptoms with erythema migrans and was treated for 10 days with amoxicillin. Serology revealed two positive unspecific bands in IgG immunoblot (p41 and 66) with slight positivity for ELISA. Ultrasound revealed synovial thickening and increased fluid. Despite the weak positive serology a diagnosis of lyme arthritis could not be excluded and intravenous antibiotic treatment with ceftriaxone was started. After two further relapses antiinflammatory therapy including intraarticular steroids were introduced with no long lasting effect. A chronical disease developed with alternate periods of swelling and almost complete remission. Ultrasound as well as MRI demonstrated ongoing signs of synovitis, therefore after further progression, a diagnostic arthroscopy was performed showing an inconspicuous knee joint. A second MRI showed focal suprapatellar enhancement and was followed by open arthrotomy revealing a histopathological proven synovial cavernous juxtaarticular hemangioma. To our knowledge, the differential diagnosis of lyme arthritis and synovial hemangioma has not yet been reported despite obvious clinical similarities. In conclusion, in children and adolescents synovial hemangioma has to be considered in differential diagnosis of recurrent knee swelling. Early diagnosis is important to prevent prolonged suffering from chronic joint swelling with probable joint damages, unnecessary treatment procedures and as well school and sports

To investigate the clinical efficiency of electrocoagulation for the treatment of noninvoluting congenital hemangioma. Sixteen infants with noninvoluting congenital hemangioma who were admitted to our hospital from January 2011 to June 2013 were included in this study. Color Doppler ultrasound was used to determine the hemangioma location, as well as its size and depth. High frequency electrocoagulation was adopted for the treatment. The output power was set at 10-20 W. The probes were inserted around the tumor or at the surface of the tumor. After switching on for 1-2 seconds, the direction and position of the probe was modulated until covering the whole tumor. After the treatment, the absorption of tumor was about 3-6 months. The efficiency was evaluated during the follow-up. Tumor atrophy was obvious after treatment in all patients. The temperature around the tumor mass was decreased, and the aberrant blood signals were decreased under the ultrasonic examination. Complete or partial atrophy were observed. The efficiency was graded as level I, II, III, IV in 0, 2, 9 and 5 patients, respectively. One patient showed local infection due to improper nursing, which was completely relieved after corresponding treatment. No severe adverse events were observed. High-frequency electrocoagulation is effective for treating noninvoluting congenital hemangioma through coagulating the aberrant blood vessels in the tumor, interrupting the vascular endothelial cell, blocking the aberrant blood flow, as well as leading to atrophy and absorption of tumor mass. Besides, no obvious scar is observed after the surgery.

Urea immunoliposome inhibits human vascular endothelial cell proliferation for hemangioma treatment

Science.gov (United States)

2013-01-01

Background Urea injection has been used in hemangioma treatment as sclerotherapy. It shrinks vascular endothelial cells and induces degeneration, necrosis, and fibrosis. However, this treatment still has disadvantages, such as lacking targeting and difficulty in controlling the urea dosage. Thus, we designed a urea immunoliposome to improve the efficiency of treatment. Methods The urea liposome was prepared by reverse phase evaporation. Furthermore, the urea immunoliposome was generated by coupling the urea liposome with a vascular endothelial growth factor receptor (VEGFR) monoclonal antibody using the glutaraldehyde cross-linking method. The influence of the urea immunoliposome on cultured human hemangioma vascular endothelial cells was observed preliminarily. Results Urea immunoliposomes showed typical liposome morphology under a transmission electron microscope, with an encapsulation percentage of 54.4% and a coupling rate of 36.84% for anti-VEGFR. Treatment with the urea immunoliposome significantly inhibited the proliferation of hemangioma vascular endothelial cells (HVECs) in a time- and dose-dependent manner. Conclusions The urea immunoliposome that we developed distinctly and persistently inhibited the proliferation of HVECs and is expected to be used in clinical hemangioma treatment. PMID:24266957

Adult hemangiomas are rare, slowly progressing vascular tumors. Potential complications include laryngeal involvement or massive tumor burden. A case of recurrent, bulky laryngeal hemangioma involving the parapharyngeal space is presented herein. The clinical course and treatment are described, and a series of MRI studies are compared to demonstrate the treatment response. A 35-year-old woman presented with progressive hoarseness, neck fullness, and intermittent dyspnea caused by a bulky laryngeal hemangioma. Steroid therapy had a limited response. Radiation therapy with a total dose of 40 Gray (Gy) in 20 fractions successfully relieved her symptoms. Image studies after therapy revealed moderate tumor regression. The patient showed no serious complications during the next 2 years of follow-up. Radiation therapy may be effective in intractable and function-threatening laryngeal hemangiomas.

Hemangiomas of the bone are benign, uncommon, slow-growing lesions accounting for occipital hemangiomas are rare, and occipital hemangiomas presenting with features of raised intracranial tension are, with only 2 cases reported to date. In this case report, we describe the unique case of a 30-year-old male patient presenting with raised intracranial pressure due to venous obstruction at the torcula. The patient underwent excision of the lesion and became symptom free. Although these are benign lesions, they can have a varied clinical presentation. An understanding of the different clinical presentations and surgical nuances in excising such tumors can lead to early diagnosis and good patient outcome. Copyright © 2017 Elsevier Inc.

Ten patients with soft tissue hemangiomas outside the central nervous system were studied with MR imaging. Eight patients were studied at 1.5 Tesla (T) with T{sub 1}-weighted and triple echo T{sub 2}-weighted sequences. Two additional patients were imaged on a 0.5-T system. The MR images were correlated with images from other modalities. It was found that prolonged T{sub 2}-weighted imaging together with standard spin echo T{sub 1} and T{sub 2} pulse sequences is a good substitute for contrast-enhanced CT and arteriographic evaluation of soft tissue hemangiomas.

The authors report here a case of hemangioma of the left parietal bone which presented headache and papilledema. This patient is a 37-year-old female who had, prior to admission, complained of increasing headache for one year and blurred vision for three months. She had no history of head injury. Local physical examinations revealed a slight bulging in her left parietal region which was insensitive to palpation and not adherent to the overlying scalp. Neurological examinations revealed bilateral papilledema and an incongruous bitemporal upper quadrant defect in the visual field. All the other neurological and laboratory data were normal. A plain skull roentogenogram showed a 9 x 9 cm osteolytic and characteristic honeycomb lesion in the parietal region. Systemic bone survey revealed a similar lesion in the right tibia which was not histologically examined. A marked accumulation of isotopes was detected on the bone scintigrams at both lesions. Selective external carotid angiograms demonstrated a tumor stain fed by the superficial temporal, occipital, and middle meningial arteries. CT scans of the brain and skull clearly showed a local thickening of and structural changes in the skull bone and also a mass effect on the brain and lateral ventricle. The lesioned bone was removed en bloc and replaced by an artificial bone. It was highly vascular, but not adherent to the overlying dura. The post-operative course was uneventful, and the headache and papilledema disappeared. Hemangioma of the skull presenting marked hyperostosis, as reported above, seems to be rare. In addition, in this case, skeletal angioma without any clinical manifestation was detected. Clinical and radiological pictures of the hemangioma of the skull and other bones were briefly discussed.

Between 1975 and 1996, 14 patients (11 females, 3 males) with vertebral hemangioma received treatment with radiotherapy. Thirteen patients had a history of back pain or lumbago and 2 patients had neurological symptoms such as sensory impairment or paraplegia. The standard dose administered was 36 Gy in 18 fractions (five treatments per week). In the 13 patients with pain, this was completely or partially relieved. The condition of a man with hypesthesia of the legs deteriorated and a woman with paraplegia who was treated with decompressive laminectomy followed by radiotherapy recovered completely after irradiation. CT scan before irradiation showed thickened trabeculae as small punctate areas of sclerosis in all patients. At MR imaging before irradiation, T2-weighted MR images showed areas of high intensity in all patients and MR images demonstrated lesion enhancement. However, none of the patients who were treated successfully with radiation demonstrated any changes of the affected vertebra in the conventional radiographic films, CT scan or MR imaging, even 5 years after irradiation. Radiological imaging is indispensable for the diagnosis of vertebral hemangiomas but does not appear to be useful for evaluating the effects of radiotherapy. (orig.)

Objective: To investigate the indication, total dose and efficacy of radiotherapy for vertebral hemangiomas. Methods: Between 1967 and 2000, 59 patients (36 female, 23 male) with vertebral hemangioma were treated with deep X-ray, electron beam, 60 Co or 6-8MV X-ray with a total dose ranging from 28 to 90 Gy and a median of 40 Gy. Results: Of the 54 evaluable cases, the overall response rate was 87.0%. The response rates were 90.2% and 83.3%, respectively, for patients treated with 34-40 Gy and more than 40 Gy (χ 2 =0.41, P=0.608). Among the 9 patients with paraplegic patients, 4 achieved complete response, 4 partial response, and only one showed no response to the treatment. Conclusions: Radiotherapy is effective and safe for symptomatic vertebral hemangioma, on condition of a suitable total dose range of 30 to 40 Gy. Patients with asymptomatic or minor symptomatic lesion should be watched and followed rather than giving immediate treatment. Radiation therapy shows slow and delayed improvement in vertebral hemangioma and the symptoms are gradually relieved or disappear in three months to seven years with a median interval of 1.5 years, even though diagnostic images show no or only minor changes after treatment

Epithelioid hemangioma is a rare vascular tumor that can occur in soft tissues or bone. The tumor is part of a spectrum of vascular tumors that also includes epithelioid hemangioendothelioma and angiosarcoma. When involving the bone, the tumor usually involves the metaphysis or diaphysis of the long tubular bones and most commonly occurs in adults. It has been rarely reported in pediatric patients, and in these reported patients, the tumor primarily involves the epiphysis. To review three cases of epithelioid hemangioma of bone occurring in pediatric patients involving the epiphysis and to explore the imaging features of this tumor. Retrospectively review three cases of epithelioid hemangioma occurring in skeletally immature patients. These tumors primarily involved the epiphyses or epiphyseal equivalent bones. One lesion was centered in the metaphysis but extended to the epiphysis. These are three cases presenting in an unusual location and at an unusual age. Epithelioid hemangioma, though rare, can occur in pediatric patients and appears to involve the epiphyses in these patients. This is in contrast to the usual age and location reported. Epithelioid hemangioma may be considered for an epiphyseal lesion in a skeletally immature patient. (orig.)

Hemangioma is the most common tumor of infancy. Although it has a basically benign nature and usually spontaneously regresses, a small percentage (5%) have complications that need treatment. Many different therapeutic modalities can be used in this tumor. To investigate the effect of a new method of treatment (intralesional bleomycin injection) in complicated hemangiomas. In the Department of Radiation Oncology at Nemazee Hospital in Shiraz, Iran, from April 1992 to October 1998, 32 patients with complicated hemangioma were treated with four to six courses of direct injection of bleomycin into the lesion. After a minimum follow-up of 6 years, there was 70 to 100% regression in 18 patients, 50 to 70% in 7 cases, and less than 50% reduction in 7 patients. Intralesional injection of bleomycin is an easy, safe, and effective therapeutic modality in complicated cutaneous hemangiomas.

To evaluate contrast enhancement patterns of hemangioma according to size, as seen during the arterial and portal venous phase of spiral CT. Overall, the most common enhancement pattern was peripheral high (44/82, 53.7%), during the arterial and portal venous phase. The second and third most common patterns were uniform high (11/82, 13.4%) and peripheral high-uniform high (9/82, 11.0%), also during the arterial and portal venous phase. In tumors smaller than 20 mm, low-low attenuation was seen in eight (9.8%), and iso-low attenuation in two (2.4%), during the arterial and portal venous phase, respectively. On two-phase spiral CT, the most common enhancement pattern of hemangioma was peripheral high, seen during the arterial and portal venous phase. However, a small hemangioma less than 2cm may show atypical patterns, including low and iso attenuation. (author). 23 refs., 1 tab., 4 figs

Full Text Available La lesión medular es una entidad neurológica causante de importantes procesos de discapacidad. Su incidencia en el país puede estar cercana a los mayores estimativos mundiales debido a las condiciones actuales de violencia. El aumento de la expectativa de vida de esta población —gracias a los avances tecnológicos y científicos en prevención, atención y manejo de complicaciones— lleva a la necesidad de proveer servicios de rehabilitación integrales que trasciendan los aspectos funcionales y permitan la inclusión social. Para este propósito es necesario un abordaje integral de la situación, que en el ámbito de la evaluación debe incluir no sólo la estimación de la condición de salud, sino todo lo relacionado con el funcionamiento de las personas en su vida diaria. La clasificación internacional del funcionamiento, la discapacidad y la salud, brinda un marco conceptual para abordar la discapacidad y el funcionamiento humano relacionado con la salud desde un enfoque biopsicosocial que articula las dimensiones corporal, individual y social de las personas y su relación con los factores del ambiente. Este enfoque de abordaje, plasmado en el instrumento de evaluación denominado WHO-DAS II, se considera un referente importante para evaluar la discapacidad asociada a la lesión medular.

Urethral hemangiomas are rare. They vary in size from pinpoint masses to extensive honeycomb-shape deformities leading to significant hematuria. For extensive lesions, therapeutic options have included extensive surgical resection and reconstruction or multistaged neodymium:yttrium-aluminum-garnet (Nd:YAG) laser photocoagulation. We report our experience with the use of potassium titanyl phosphate (KTP/532) laser for treatment of the extensive form. A 7-year-old boy presented with a 2-week history of urethral bleeding. He had extensive hemangiomas of the genital and perineal regions. Cystourethroscopy disclosed diffusely scattered honeycomb-shape hemangiomatous malformation of the anterior urethra. KTP/532 laser energy was delivered transurethrally to the hemangiomatous areas until they blanched. The Foley catheter was removed 24 hours postoperatively, and the patient voided clear urine without difficulty. He has remained trouble-free for more than 2 years. Judicious endoscopic single-stage therapy with KTP/532 laser may obviate open surgical intervention in most cases of extensive and symptomatic urethral hemangiomas. In view of our observation and the literature, KTP/532 laser therapy should be considered the first line of treatment.

Cavernous hemangiomas of penis are rare benign lesions infrequently described in the literature. No completely satisfactory treatment has been found to correct the cosmetic deformities especially the extensive hemangiomas of corpus penis. In light of the promising application of copper wire/needle in vascular malformations, we began a clinical study to investigate the safety, feasibility, and cosmetic effect of copper wire therapy in treating cavernous hemangioma of penis. Seven patients ranging in age from 12 to 32 years with penile cavernous hemangiomas entered our study from 2005 to 2011. All patients received treatments with percutaneous copper wires. Perioperative data including mean operation time, estimated blood loss, length of copper wire retention, and length of hospital stay were analyzed. All possible complications were noted, and cosmetic result was evaluated. Patients were followed up after discharge from the hospital. All operations were successful, and no obvious complications were observed. The patients were satisfied with the aesthetic results. Follow-up time ranged from 1 to 5 years. Recurrence was discovered in a patient with the largest lesion of corpus penis 2 months after the treatment. Secondary procedure was carried out with the same technique, and no lesions were found later. The shortage of studies on this topic prevented us from defining a therapeutic reference standard. The results of our study confirmed that copper wire therapy was a simple, safe, and useful option for penile cavernous hemangioma. © 2013 International Society for Sexual Medicine.

Masson's hemangioma is a rare benign vascular condition with a papillary intravascular endothelial proliferation which may appear either as a primary form as a secondary form in a pre-existing vascular process. CT and angiographic features of 2 cases with Masson's hemangioma were presented. Both of them were located extra-axially in the posterior fossa. CT findings were not specific in both cases; One showed homogeneously enhancing mass, simulating meningioma. And the other demonstrated a multiocular rim enhancing mass. However, the angiographic features were rather characteristic; Both cases showed persistent vascular poolings of contrast media which were supplied form the meningeal vessels. Angiographic differential diagnosis of similar lesions in the posterior fossa is discussed

Full Text Available Hemangiomas are neoplastic proliferations of endothelial cells, characterized by a period of growth after birth, and eventual spontaneous involution. The course can be uneventful with spontaneous resolution; or it may be marked by complications such as infection, bleeding, ulceration, visual defects and feeding difficulties. Apart from these, rare life-threatening complications such as congestive heart failure and consumption coagulopathy may also be seen. Although hemangiomas commonly occur in the head and neck region, intraoral occurrence is relatively rare. A port wine stain is defined as a macular telangiectatic patch which is present at birth and remains throughout life. They may be localized or extensive, affecting a whole limb. This article reports a rare case of co-occurrence of port wine stain with intraoral hemangioma.

To study the utility of logistic regression and the neuronal network in the diagnosis of cranial hemangiomas. Fifteen patients presenting hemangiomas were selected form a total of 167 patients with cranial lesions. All were evaluated by plain radiography and computed tomography (CT). Nineteen variables in their medical records were reviewed. Logistic regression and neuronal network models were constructed and validated by the jackknife (leave-one-out) approach. The yields of the two models were compared by means of ROC curves, using the area under the curve as parameter. Seven men and 8 women presented hemangiomas. The mean age of these patients was 38.4 (15.4 years (mea ± standard deviation). Logistic regression identified as significant variables the shape, soft tissue mass and periosteal reaction. The neuronal network lent more importance to the existence of ossified matrix, ruptured cortical vein and the mixed calcified-blastic (trabeculated) pattern. The neuronal network showed a greater yield than logistic regression (Az, 0.9409) (0.004 versus 0.7211± 0.075; p<0.001). The neuronal network discloses hidden interactions among the variables, providing a higher yield in the characterization of cranial hemangiomas and constituting a medical diagnostic acid.

This study aimed to describe 99mTc-labeled RBC scintigraphy as a diagnostic method for orbital cavernous hemangiomas and to evaluate this diagnostic tool according to surgical outcomes. Fifty-five patients with clinical and radiological (US, CT, and/or MRI) suspicion of unilateral cavernous hemangioma of the orbit underwent 99mTc-RBC SPECT study.Qualitative and semiquantitative evaluations were performed, and results were statistically analyzed. SPECT images showed focal uptake in the orbital mass in 36 of 55 patients. Nineteen patients had a negative scintigraphic pattern, with concordance of early and late absence of uptake of 99mTc-RBC.Our procedure showed 100% sensitivity and 88.9% specificity for the diagnosis of orbital cavernous hemangioma, with a positive predictive value of 90.9% and a negative predictive value of 100%. 99mTc-RBC imaging is safe, easy to perform, and highly accurate in providing adequate clinical and surgical management. As a noninvasive and highly specific method for diagnosing orbital hemangioma, 99mTc-RBC scintigraphy can avoid more invasive imaging or biopsy.

Because US plays a key role in the initial evaluation of hepatic hemangiomas, knowledge of the entire spectrum of US appearances of these tumors is important. Most hemangiomas have a distinctive US appearance, and even with those with atypical appearances on conventional gray-scale US, specific diagnoses can be made using pulse-inversion harmonic US with contrast agents. In this essay, we review the spectrum of US appearances of hepatic hemangiomas on conventional gray-scale, power Doppler, and pulse-inversion harmonic US with contrast agents. (author)

2006-01-01

We wanted to determine the frequency of peritumoral sparing of fatty infiltration (PTSF) around hepatic hemangioma in hepatic steatosis and to evaluate the finding of these tumors on dynamic contrast-enhanced MR imaging and on sonography. This study included 76 hemangiomas in 67 patients suffering with hepatic steatosis. A diagnosis of hemangioma was based on the histologic findings, hemangioma SPECT or a compatible enhancement pattern on the dynamic contrast-enhanced MR study. For chemical shifting, PTSF was defined when there wasn't any decrease in signal intensity of the liver parenchyma on the opposed-phase images as compared with the in-phase images, and this intensity appeared as a hyperintense area around the tumor. We evaluated the frequency of PTSF and we analyzed if the presence of PTSF was related to the tumor size, the rapidity of enhancement or an associated arterioportal shunt. Among those, sonographic images were available in 55 hemangiomas. We also evaluated the sonographic appearances of hemangiomas with PTSF. Of the 76 hemangiomas, PTSF was noted on the MR chemical-shift images in 57 hemangiomas (75%). There was no significant relationship between tumor size and the presence of PTSF (ρ = .578). However, this finding was more frequently found in high-flow hemangiomas than in the slow-flow ones (ρ = .0038) and it was also related to the presence of associated arterioportal shunt (ρ = .0158). Sonographically, hemangiomas with PTSF were commonly surrounded by a peritumoral low-echoic area (28/41, 68%); these tumors more frequently showed a thin high-echoic rim on sonography than did the tumors without this finding (ρ = .0055). PTSF is commonly seen in hemangiomas in hepatic steatosis patients. Hepatic hemangiomas with PTSF tend to show rapid enhancement on dynamic MR imaging and this is accompanied by arterioportal shunt. They tend to be seen as an iso-or low-echoic mass with a thin high-echoic rim on sonography, and the mass is commonly

Full Text Available CONTEXT:The incidence of hepatic hemangiomas ranges from 0.4% to 20% in the general population. Conventional ultrasound is usually the first diagnostic method to identify these hemangiomas, typically as an incidental finding. Ultrasonography with second generation contrast materials is being used in various areas of hepatology, yielding similar results to those obtained with computerized tomography and magnetic resonance imaging in the diagnosis of hepatic hemangiomas. OBJECTIVE: To evaluate the agreement between ultrasound with perflutrene contrast and magnetic resonance imaging in the diagnosis of hepatic hemangiomas. METHODS: A total of 37 patients were prospectively examined between January 2006 and August 2008. A total of 57 hepatic nodules were documented in this group as incidental findings on routine ultrasound exams. The 37 patients were administered perflutrene contrast without adverse reactions, and were all submitted to magnetic resonance exams. RESULTS: Conventional ultrasound identified 15 patients with nodules typical of hemangiomas and 22 patients with other nodules. In 35 patients, the contrast characteristics were consistent with hepatic hemangiomas. CONCLUSION: Agreement between the data obtained from ultrasound with contrast and magnetic resonance was 94.5%. In discordant cases, the magnetic resonance diagnosis prevailed. In the case which presented indeterminate findings on contrast ultrasonography, magnetic resonance was repeated after 3 months, confirming the diagnosis of a hepatic hemangioma. A biopsy was performed on the suspected malignant nodule which also confirmed the presence of a hepatic hemangioma. Ultrasonography with contrast has the advantages of being more accessible to the public at large and lower cost than magnetic resonance. The results of our study highlight the need for a new protocol in hepatic nodules incidentally identified on conventional ultrasonography. In the case of typical hemangiomas

Objective: To evaluate the long-term effect of hepatic arterial embolization with pingyanmycin-lipiodol emulsion (PLE) in patients with cavernous hemangiomas of the liver (CHL) and its influence factors. Methods: One hundred and fifty-six hemangiomas that were diagnosed by imaging examinations or confirmed pathologically by surgery in 105 patients with integral follow-up data were analyzed retrospectively in this paper. All hemangiomas were divided into 4 groups according to their size (the largest size of hemangioma) by the authors as follows: A group (≤3 cm, n=25); B group (>3 cm and 2 test respectively. And the influence factors, included of the variant size of hemangiomas, abundant or sparse of abnormal sinusoids and the number of treatment procedures, were also analyzed respectively. Results: The total effective rate of the 156 hemangiomas in 105 patients was 92.95% (145/156). After single procedure of hepatic arterial embolization with PLE, the total effective rate of A and B groups were 100% (57/57), that of C and D groups were 85.86% (85/99), and the difference reach significant (X 2 =8.8553, P 2 =5.2642, P<0.05) than those of group with single procedure (72.73%, 8/11). Conclusions: A best long-term curative effect (complete cure) is usually obtained in the small hemangiomas with abundant abnormal sinusoids, and a satisfactory long-term curative effect can also be achieved in the larger or multiple hemangiomas, particularly in those hemangiomas with abundant abnormal sinusoids by using the repeat procedures of hepatic arterial embolization with PLE.

To compare the enhancement characteristics of small hemangiomas seen on multiphase spiral CT and dynamic MR imaging. Thirteen patients with 20 hepatic hemangiomas less than 25mm in diameter underwent both multiphase spiral CT and dynamic MR imaging. All lesions were assigned to one of three classified into 3 categories according to the enhancement pattern seen on multiphase spiral CT : typical delayed pooling, atypical early enhancement, or continuous low attenuation. The enhancement patterns seen on spiral CT and on dynamic MRI were correlated. On CT scans, ten lesions (50%) showed delayed pooling. Six (30%) showed early arterial enhancement and four (20%) showed continuous low attenuation. On delayed-phase MRI, all lesions showed delayed high signal intensity compared to adjacent liver parenchyma. Four of six lesions with early enhancement on CT showed peripheral globular enhancement on early arterial-phase MRI. On multiphase spiral CT scans, small hemangiomas can show variable atypical enhancement features. In this situation, contrast-enhanced dynamic MRI is helpful for the diagnosis of hemangiomas

Objective: To analyze the MRI findings of hemangiomas derived from soft tissue. Methods: MRI was performed on 32 cases with mass in the peripheral soft tissue. All cases were confirmed to be hemangioma histo-pathologically. Results: The masses were classified as four patterns on this series, namely: cavernous hemangiomas, 15 cases (46.9%), displayed as a spindle-shaped or irregular mass; Racemose, 9 cases (28%), had an honeycombed or racemose appearance; Capillary, 5 cases (15.6%), with an elongated mass-like configuration; Mixed, 3 case(9.4%), showed as an amouphus mass. The masses usually had equal or higher signal intensity as compared to muscle on T 1 WI and markedly high signal intensity on T 2 WI. Focal inhomogeneities of the lesions in pathological study represent areas of fibrosia, fat, thrombosis, smooth muscle or calcificatin. Conclusion: MRI is an useful tool not only to identifying the locatoion of the mass but also could specify the peripheral soft tisure hemangioma. (authors)

Full Text Available Hemangioma is a benign tumor of blood and lymphatic vessels. It is common in skin, mucosa and soft tissues, and its occurrence in lymph nodes is extremely rare. A 10 year-old she-camel was slaughtered at Nyala slaughterhouse, South Darfur State, Sudan. Grossly, the carcass was emaciated. The left ventral superficial cervical lymph node was enlarged, hard on palpation and protruded outside the body. Its cut surface was dark red in color and measured (18 cm in diameter. Histopathologically, the sections revealed vascular masses were composed of non-encapsulated clusters of small and medium sized with thick and thin-walled, filled with blood, separated by courageous stroma and surrounded by closely packed proliferating capillaries. To the best of our knowledge, this is the first record of the left ventral superficial cervical lymph node hemangioma in a camel in the Sudan.

This study explored the feasibility and clinical efficacy of expanded flap to repair facial scar left by radiotherapy of hemangioma. From March 2000 to April 2011, 13 cases of facial cicatrices left by radiotherapy of hemangioma have been treated with implantation surgery of facial skin dilator under local anesthesia. After water flood expansion for 1-2 months, resection of facial scar was performed, and wound repairing with expansion flap transfer was done. Thirteen patients were followed up from 5 months to 3 years. All patients tolerated flap transfer well; no contracture occurred during the facial expansion flap transfer. The incision scar was not obvious, and its color and texture were identical to surrounding skin. In conclusion, the use of expanded flap transfer to repair the facial scar left by radiotherapy of hemangioma is advantageous due to its simplicity, flexibility, and large area of repairing. This method does not affect the subsequent facial appearance.

The purpose of this study is to investigate whether acoustic radiation force impulse (ARFI) elastography with ARFI quantification and ARFI 2-dimensional (2D) imaging is useful for differentiating hepatic hemangiomas from malignant hepatic tumors. One-hundred-and-one tumors in 74 patients were included in this study: 28 hemangiomas, 26 hepatocellular carcinomas (HCCs), three cholangiocarcinomas (CCCs), 20 colon cancer metastases and 24 other metastases. B-mode ultrasound, ARFI 2D imaging, and ARFI quantification were performed in all tumors. Shear wave velocities (SWVs) of the tumors and the adjacent liver and their SWV differences were compared among the tumor groups. The ARFI 2D images were compared with B-mode images regarding the stiffness, conspicuity and size of the tumors. The mean SWV of the hemangiomas was significantly lower than the malignant hepatic tumor groups: hemangiomas, 1.80 ± 0.57 m/sec; HCCs, 2.66 ± 0.94 m/sec; CCCs, 3.27 ± 0.64 m/sec; colon cancer metastases, 3.70 ± 0.61 m/sec; and other metastases, 2.82 ± 0.96 m/sec (p < 0.05). The area under the receiver operating characteristics curve of SWV for differentiating hemangiomas from malignant tumors was 0.86, with a sensitivity of 96.4% and a specificity of 65.8% at a cut-off value of 2.73 m/sec (p < 0.05). In the ARFI 2D images, the malignant tumors except HCCs were stiffer and more conspicuous as compared with the hemangiomas (p < 0.05). ARFI elastography with ARFI quantification and ARFI 2D imaging may be useful for differentiating hepatic hemangiomas from malignant hepatic tumors.

To investigate the use of diffusion weighted magnetic resonance imaging (DWI) and the apparent diffusion coefficient (ADC) values in the diagnosis of hemangioma. The study population consisted of 72 patients with liver masses larger than 1 cm (72 focal lesions). DWI examination with a b value of 600 s/mm2 was carried out for all patients. After DWI examination, an ADC map was created and ADC values were measured for 72 liver masses and normal liver tissue (control group). The average ADC values of normal liver tissue and focal liver lesions, the "cut-off" ADC values, and the diagnostic sensitivity and specificity of the ADC map in diagnosing hemangioma, benign and malignant lesions were researched. Of the 72 liver masses, 51 were benign and 21 were malignant. Benign lesions comprised 38 hemangiomas and 13 simple cysts. Malignant lesions comprised 9 hepatocellular carcinomas, and 12 metastases. The highest ADC values were measured for cysts (3.782±0.53×10(-3) mm(2)/s) and hemangiomas (2.705±0.63×10(-3) mm(2)/s). The average ADC value of hemangiomas was significantly higher than malignant lesions and the normal control group (p<0.001). The average ADC value of cysts were significantly higher when compared to hemangiomas and normal control group (p<0.001). To distinguish hemangiomas from malignant liver lesions, the "cut-off" ADC value of 1.800×10(-3) mm(2)/s had a sensitivity of 97.4% and a specificity of 90.9%. To distinguish hemangioma from normal liver parenchyma the "cut-off" value of 1.858×10(-3) mm(2)/s had a sensitivity of 97.4% and a specificity of 95.7%. To distinguish benign liver lesions from malignant liver lesions the "cut-off" value of 1.800×10(-3) mm(2)/s had a sensitivity of 96.1% and a specificity of 90.0%. DWI and quantitative measurement of ADC values can be used in differential diagnosis of benign and malignant liver lesions and also in the diagnosis and differentiation of hemangiomas. When dynamic examination cannot distinguish cases with

Highlights: • We evaluated the impact of share wave elastography technique in differentiation hepatic hemangiomas from malignant liver tumors in pediatric population. • Share wave technique can increase the diagnostic capability of conventional ultrasonography in the differential diagnosis of liver tumors in children. • Share wave elastography is a potential adjunctive diagnostic technique for pediatric liver tumors. - Abstract: Objective: In children it is crucial to differentiate malignant liver tumors from the most common benign tumor, hepatic hemangiomas since the treatment strategies are quite different. We aimed to evaluate the efficiency of shear wave elastography (SWE) technique in differentiation of malignant hepatic tumors and hepatic hemangiomas. Methods: Twenty patients with hepatic tumor were included in our study. Two radiologists performed SWE for 13 patients with malignant hepatic tumors including hepatoblastoma (n = 7), hepatocellular carcinoma (n = 3), metastasis (n = 2), embryonal sarcoma (n = 1) and 7 patients with hepatic hemangioma. All of our patients were between the age of 1 and 192 months (mean age: 56.88 months). Receiver operating characteristic analysis was achieved to evaluate the diagnostic accuracy of SWE and to determine the optimal cut-off value in differentiation hepatic hemangioma from malignant hepatic tumors. Results: The mean SWE values (in kPa) for the first observer were 46.94 (13.8–145) and 22.38 (6.6–49.6) and those for the second observer were 57.91 (11–237) and 23.87 (6.4–57.5), respectively for malignant hepatic tumors and hepatic hemangiomas. The SWE values of malignant hepatic tumors were significantly higher than those of hepatic hemangioma (p = 0.02). The inter-observer agreement was almost perfect (0.81). The area under the receiver operating characteristic curve of SWE for differentiating the hepatic hemangioma from malignant hepatic tumors was 0.77 with a sensitivity of 72.7% and a specificity of 66

Infantile hemangioma (IH) is the most common vascular tumor in children. It is controversial whether IHs has effects on the quality of life (QOL) in patients of whom IH poses no threat or potential for complication. Thus, we conducted this study to evaluate the q QOL in patients with IH and find the predictors of poor QOL. The PedsQL 4.0 Genetic Core Scales and the PedsQL family information form were administered to parents of children with IH and healthy children both younger than 2-year-old. The quality-of-life instrument for IH (IH-QOL) and the PedsQL 4.0 family impact module were administered to parents of children with IH. We compared the PedsQL 4.0 Genetic Core Scales (GCIS) scores of the two groups. Multiple step-wise regression analysis was used to determine factors that influenced QOL in children with IH and their parents. Except for physical symptom, we found no significant difference in GCIS between patient group and healthy group (P = 0.409). The internal reliability of IH-QOL was excellent with the Cronbach's alpha coefficient for summary scores being 0.76. Multiple step-wise regression analysis showed that the predictors of poor IH-QOL total scores were hemangioma size, location, and mother's education level. The predictors of poor FIM total scores were hemangioma location and father's education level. The predictors of poor GCIS total scores were children's age, hemangioma location and father's education level. The findings support the feasibility and reliability of the Chinese version of IH-QOL to evaluate the QOL in children with IH and their parents. Hemangioma size, location and education level of mother are important impact factors for QOL in children with IH and their parents.

A current therapeutic challenge of vascular lesions is that they do not always respond effectively to laser treatment. Information on targeted vessels could potentially be used to guide laser treatments. Optical coherence tomography (OCT) is a useful tool for the non-invasive imaging of tissues, including skin hemangiomas and port wine birthmarks. Dynamic OCT is able to rapidly characterize cutaneous blood vessels. The primary goal of this study was to demonstrate the ability of bedside OCT to image (i) overall vessel pattern; (ii) individual vessel morphology, diameter and depth; and (iii) total vessel density as a function of depth in infantile hemangiomas and port wine birthmarks (PWB). This IRB approved, observational clinical trial was performed among healthy volunteers ages 3 months-73 years old. All patients presented for laser treatment of either infantile hemangiomas or PWB with skin types ranging from Fitzpatrick I-V. OCT imaging of 49 hemangioma and PWB scans were performed pre- and post-treatment. The diameter and depth of the blood vessels making up the vascular lesions were measured. In addition, normal skin was scanned for comparison. Five datasets for infantile hemangiomas and five for PWB that were without motion artifacts were analyzed. Scanned lesions exhibited variable and highly heterogeneous blood vessel patterns with vessel diameters ranging from 20 to 160 μm, suggesting that the laser treatment with single pulse durations may not be optimal. The largest blood vessel diameter observed (160 μm) may not be adequately treated by commonly used pulsed dye laser pulse durations. OCT allowed rapid, non-invasive characterization of the diameter and depth of blood vessels in individual vascular lesions. Imaged lesions consisted of a heterogeneous population of vessel sizes, morphologies, and depth. Future studies could utilize this information to assist development of individualized treatment protocols in an effort to improve vascular birthmark

Full Text Available Rania El Essawy,1 Rasha Essameldin Galal21Department of Ophthalmology, 2Department of Pediatrics, Faculty of Medicine, Cairo University, Cairo, EgyptBackground: The purpose of this study was to evaluate the results and complications of early surgical resection of large amblyogenic subdermal eyelid hemangiomas in infants after prior short-term parenteral administration of corticosteroids.Methods: Sixteen infants were given dexamethasone 2 mg/kg/day in two divided doses for three consecutive days prior to scheduled surgical excision of large eyelid hemangiomas. The lesions were accessed via an upper eyelid crease, subeyebrow incision, or a lower eyelid subciliary incision.Results: In all cases, surgical excision of the entire lesion was possible with no significant intraoperative or postoperative complications. The levator muscle/aponeurosis complex was involved in 31.25% of cases and was managed by reinsertion or repositioning without resection. A satisfactory lid position and contour with immediate clearing of the visual axis was achieved in all but one case (93.8%.Conclusion: Parenteral corticosteroids helped in reducing volume and blood flow from the hemangiomas, allowing for very early total excision of large subdermal infantile hemangiomas without significant intraoperative hemorrhage. This resulted in immediate elimination of any reason for occlusion amblyopia. Long-term follow-up of visual development in these patients would help to demonstrate the effectiveness of this strategy compared with more conservative measures.Keywords: large eyelid hemangiomas, early surgical resection, parenteral corticosteroids

We performed this retrospective study to investigate the outcomes of patients with hemangioma of the cavernous sinus after fractionated radiotherapy. We analyzed 10 patients with hemangioma of the cavernous sinus who were treated with conventional radiotherapy between January 2000 and December 2016. The median patient age was 54 years (range, 31–65 years), and 8 patients (80.0%) were female. The mean hemangioma volume was 34.1 cm"3 (range, 6.8–83.2 cm"3), and fractionated radiation was administered to a total dose of 50–54 Gy with a daily dose of 2 Gy. The median follow-up period was 6.8 years (range, 2.2–8.8 years). At last follow-up, the volume of the tumor had decreased in all patients. The average tumor volume reduction rate from the initial volume was 72.9% (range, 18.9–95.3%). All 10 of the cranial neuropathies observed before radiation therapy had improved, with complete symptomatic remission in 9 cases (90%) and partial remission in 1 case (10%). No new acute neurologic impairments were reported after radiotherapy. One probable compressive optic neuropathy was observed at 1 year after radiotherapy. Fractionated radiotherapy achieves both symptomatic and radiologic improvements. It is a well-tolerated treatment modality for hemangiomas of the cavernous sinus

Full Text Available Background: Lobular capillary hemangioma of the nasal cavity is an uncommon benign vascular tumor of unknown etiology. There have been only very few case reports in Taiwan. Aims: This study aimed to analyze the clinical features, radiological findings, treatment modalities, and outcome of lobular capillary hemangioma treated at a teaching hospital in Taiwan during a period of 10 years. Study Design: Descriptive study. Methods: Retrospective chart reviews were performed on patients who were diagnosed with lobular capillary hemangioma of the nasal cavity at Kaohsiung Armed Forces General Hospital, Kaohsiung, Taiwan, from January 2003 to December 2012. Data retrieved included age, gender, clinical symptoms, computed tomography (CT findings, treatment modalities, and outcome for further analysis. Results: Of the 15 patients identified, there were five males and ten females ranging from 17 to 86 years of age, with a mean age of 43.8±20.2. Epistaxis was the most common presenting symptom. All patients presented a unilateral nasal lobular capillary hemangioma. The most commonly affected site was the anterior nasal septum, followed by the inferior turbinate, vestibule, middle turbinate, and posterior nasal septum. All lesions presented as soft tissue density without bony erosions under CT examination. Endoscopic excisional surgery (n=12 or classical local excision (n=3 was performed for complete removal of the hemangioma. No evidence of recurrence was observed with 6 to 75 months of follow-up. Conclusion: Lobular capillary hemangioma of the nasal cavity was usually found to occur in anterior septum with epistaxis. Complete excision with endoscopic surgery or classical local excision was recommended and recurrence can be prevented.

CT-Scans of 29 histologically proven cavernous hemangiomas were evaluated with respect to their location, shape, delineation from surrounding tissue, contrast-enhancement, and secondary changes of the bony orbit. Whenever a round or oval tumor, located in the outer upper muscle cone, sharply delineated from surrounding tissue, unattached to optic nerve and ocular muscles, spares a small triangular space in the orbital apex, it is in all probability a cavernous hemangioma. Evaluation of the tumors shape and its separation from surrounding tissues requires imaging in multiple sections in two planes oriented, if possible, at right angles. Changes in position of the optic nerve and eye muscles in different directions of gaze demonstrated by CT rule out significant tumor-attachments. The portion of the intraconal space least affected by optic nerve shifts and muscle contractions during eye movements, as demonstrated by CT, is the upper outer quadrant, the site preferred by the mobile tumor. Tumors which cannot be differentiated from cavernous hemangiomas by CT-criteria are rare usually benign. Reports of rare examples of well delineated or encapsulated malignant intraconal lesions indicate the possibility - however remote - of mistaking a malignant tumor for a cavernous hemangioma by CT.

2006-01-01

Purpose: To identify and compare magnetic resonance imaging (MRI) characteristics, with and without intravenous contrast medium, of cavernous synovial hemangiomas and cystic synovial hyperplasia. Material and Methods: Four cases of cavernous synovial hemangioma and five of cystic synovial hyperplasia of the knee were studied retrospectively. The patients (5 F and 4 M; 15-25 years of age) all had long-standing knee pain. At clinical examination we observed elastic swelling and pain without significant joint effusion. The patients underwent conventional radiography and MRI without and following intravenous contrast medium before arthroscopic biopsy. Results: The radiographs were interpreted as negative in all patients. MRI examination without contrast medium revealed a similar multicystic appearance for both lesions. Following intravenous contrast agent administration, cavernous synovial hemangiomas demonstrated avid, rather homogenous enhancement, whereas cystic synovial hyperplasia demonstrated less intense, peripheral enhancement only. Arthroscopy with histological examination of the lesions confirmed the MRI diagnosis in every case. Conclusion: In our experience, cavernous synovial hemangioma and cystic synovial hyperplasia have a similar appearance on unenhanced MRI, but can be reliably differentiated on the basis of enhancement characteristics following intravenous contrast administration. Keywords: Cavernous synovial hemangioma; cystic synovial hyperplasia; knee; MRI

2006-01-01

Purpose: The aim of this study was to compare, on a retrospective basis, the results of therapy in patients with uveal hemangioma treated with photon or proton irradiation at a single center. Methods and Materials: From 1993 to 2002 a total of 44 patients were treated. Until 1998 radiotherapy was given with 6 MV photons in standard fractionation of 2.0 Gy 5 times per week. In 1998 proton therapy became available and was used since then. A dose of 20 to 22.5 Cobalt Gray Equivalent (CGE) 68 MeV protons was given on 4 consecutive days. Progressive symptoms or deterioration of vision were the indications for therapy. Results: Of the 44 patients treated, 36 had circumscribed choroidal hemangiomas and 8 had diffuse choroidal hemangiomas (DCH) and Sturge-Weber syndrome. Of the patients, 19 were treated with photons with a total dose in the range of 16 to 30 Gy. A total of 25 patients were irradiated with protons. All patients with DCH but 1 were treated with photons. Stabilization of visual acuity was achieved in 93.2% of all patients. Tumor thickness decreased in 95.4% and retinal detachment resolved in 92.9%. Late effects, although generally mild or moderate, were frequently detected. In all, 40.9% showed radiation-induced optic neuropathy, maximum Grade I. Retinopathy was found in 29.5% of cases, but only 1 patient experienced more than Grade II severity. Retinopathy and radiation-induced optic neuropathy were reversible in some of the patients and in some resolved completely. No differences could be detected between patients with circumscribed choroidal hemangiomas treated with protons and photons. Treatment was less effective in DCH patients (75%). Conclusions: Radiotherapy is effective in treating choroidal hemangiomas with respect to visual acuity and tumor thickness but a benefit of proton therapy could not be detected. Side effects are moderate but careful monitoring for side effects should be part of the follow-up procedures

Full Text Available PHACE association is a rare neurocutaneous condition in which facial hemangiomas associate with a spectrum of posterior fossa malformations, arterial cerebrovascular anomalies, cardiovascular anomalies, and eye anomalies. We reported a case of PHACE association in a premature infant showing facial, intracranial, and oropharyngeal hemangiomas with evidence of the Dandy-Walker variant and complicated cardiovascular anomalies, including a right-sided aortic arch and an atypical patent ductus arteriosus arising from a tortuous left subclavian artery. To our knowledge, intracranial hemangiomas are rare in PHACE association, and a concomitant oropharyngeal hemangioma has not been previously reported in the PHACE association literature. In infants presenting with large, plaque-like facial hemangiomas, it is important to conduct active cardiovascular and neurological evaluations. Special attention should be given to the laryngoscopic examination to search for additional hemangiomas in the airway.

A combination of giant hepatic hemangioma and diffuse hemangiomatosis is extremely rare in adults. Even when they are large, hemangiomas are soft and rarely compress adjacent structures. A 78-year-old man presented with abdominal pain and distension. Ultrasonography, computed tomography, and magnetic resonance imaging demonstrated a large expansile mass replacing the medial segment and caudate lobe with diffusely scattered nodules in the entire liver. The large hilar mass contained a central nonenhancing area and had a mass effect, leading to left portal vein occlusion. The image findings also revealed two unprecedented findings: left lateral segmental atrophy of the liver and recent portomesenteric vein thrombosis. The hepatic lesions were confirmed with hemangiomas by ultrasonography-guided biopsy. We diagnosed intrahepatic portal vein obstruction caused by a mass effect of giant hepatic hemangioma coexistent with diffuse hemangiomatosis, resulting in hepatic segmental atrophy and extrahepatic portal vein thrombosis.

1982-01-01

Generalized enchondromatosis is a newly delineated type of enchondromatosis. Radiographically there are multiple enchondromata in almost all metaphyses of the long and short tubular bones and the lesions are in almost the same stage of development with mild platyspondyly and skull deformity. The pelvic changes are characteristic and, together with the metaphyseal changes of the long and short tubular bones, are probably diagnostic of this disorder. The present case demonstrates advanced radiographic features of this disorder associated with unusual soft tissue calcifications and hemangiomas. The presence of hemangiomas in our case as well as three cases in the literature suggests this feature is more than a coincidence. (orig.)

The purpose of this research is to define the appearance of hepatic hemangiomas on T{sub 2}-weighted and dynamic gadolinium-enhanced FLASH magnetic resonance (MR) images. With 1.5-T MR imaging, T{sub 1} and T{sub 2}-weighted spin echo and dynamic gadolinium-enhanced FLASH, and postcontrast, T{sub 1}-weighted spin echo images were obtained in 74 patients. Signal intensity, internal architecture, margin on T{sub 2}-weighted images and pattern of enhancement on dynamic images were correlated with tumor size. As a result, in all, 96 hemangiomas were depicted. On T{sub 2}-weighted images, 90 tumors were very hyperintense and 6 tumors were slightly hyperintense relative to the surrounding liver. Tumors of very hyperintensity, homogenous architecture or with septation tended to be larger than those without these findings (p<0.0001). 53 tumors showed peripheral enhancement, while 17 tumors showed total enhancement. Tumor size of former enhancement pattern was significantly larger than that of later enhancement pattern. So we concluded that MR appearance of hemangioma has close relationship with tumor size.

There is no single point of view on pathogenesis of hemangiomas. The authors investigated the ABO blood types in 52 patients with hepatic hemangiomas (Group 1) and 1000 control patients (Group 2). The character of changes in the liver was established by means of reontgenoradionuclide investigation methods. The study demonstrated 61.5 % of the A blood type among the patients of Group 1. This was significantly higher than in the Group 2 and representative groups from literature (P < 0.001). Taking into account that the cells of both blood and blood vessels are formed in embryos through the mesenchyma and the heritability of blood group antigens, it is supposed that the results obtained support the genetic determination theory of pathogenesis of hepatic hemangioamas

Epithelioid hemangioma of the colon: a case report

Full Text Available CONTEXT: Epithelioid hemangioma or angiolymphoid hyperplasia with eosinophilia is an uncommon benign vascular neoplasm that is usually located on the face or neck. Exceptionally, it has been described affecting the colon, with only two such cases described in the worldwide literature. The aim here was to present a case of primary epithelioid hemangioma of the sigmoid colon with confirmation by immunohistochemical examination. CASE REPORT: A 37-year-old woman had had a complaint of intermittent abdominal pain for six months. Two months after the condition started, she began to present changes in her intestinal habit, with evacuations containing blood and mucus and a weight loss of 4 kg over this period. At physical examination, a palpable mass was noted in the lower left quadrant of the abdomen. Neoplasia of the colon was clinically suspected and she underwent colonoscopy. This demonstrated the presence of a vegetating sessile lesion of approximately 5 cm in diameter, at a distance of 36 cm from the anal margin. It occupied 80% of the intestinal lumen. A biopsy collected during the examination suggested a diagnosis of neoplasia of vascular origin. After surgical resection, histopathological examination of the resected specimen confirmed the diagnosis of epithelioid hemangioma of the colon, which was backed up by the immunohistochemical panel (factor VIII, Ki-67, CD-34. At present, three years after the surgery, the patient is asymptomatic, she has recovered her normal weight and she has normal findings from control colonoscopy. Despite the rarity of neoplasia of vascular origin, this possibility should be considered in the differential diagnosis for colorectal tumors.

The purpose of this study is to compare single-shot echo-planar MR imaging (EPI) with breath-hold fast T2-weighted imaging (HASTE or Turbo spin-echo T2WI) for evaluation of the role of EPI in distinguishing small hepatocellular carcinoma from cavernous hemangioma. We retrospectively evaluated MR images of 35 patients (21 cases of small HCC and 14 cases of cavernous hemangioma). EPI and breath-hold fast T2WI images were obtained and compared on the basis of lesion detection sensitivity, lesion-to-liver signal intensity ratio (SIR), contrast ratio (CR), and lesion-to-liver contrast to noise ratio (CNR). For the detection of small HCC, the sensitivity of EPI and breath-hold fast T2WI were equal in 14 of 21 cases (71.4%). The detection sensitivity of cavernous hemangioma with EPI and breath-hold fast T2WI was 100 % (14/14). Mean SIR on breath-hold fast T2WI was 2.02 ± 0.45 for small HCC and 3.65 ± 0.97 for cavernous hemangioma; on EPI, the corresponding figures were 2.91 ± 0.57 for cavernous hemangioma; On EPI, the figures obtained were 2.27 ± 0.52 and 6.26 ± 2.19, respectively. Mean CNR on breath-hold fast T2WI was 14.24 ± 4.098 for small HCC and 50.28 ± 10.96 for cavernous hemangioma, while on EPI, the corresponding figures were 13.84 ± 3.02 and 45.44 ± 11.21. In detecting focal hepatic mass, the sensitivity of EPI and breath-hold fast T2WI are comparable for the diagnosis of small HCC and cavernous hemangioma, EPI can provided additional information.

Full Text Available Objective To determine the prevalence of liver cysts and hemangiomas in the general population and in cirrhotic patients. Materials and Methods Retrospective, observational, and cross-sectional study selecting consecutive magnetic resonance imaging studies performed in the period from February to July 2011. A total of 303 patients (187 women and 116 men with mean age of 53.3 years were included in the present study. Patients with previously known liver lesions were excluded. The images were consensually analyzed by two observers in the search for simple liver cysts and typical liver hemangiomas, according to universally accepted imaging criteria. Lesions prevalence, diameters and location were determined in both cirrhotic and non-cirrhotic individuals. Results The authors observed prevalence of 8.6% for hemangiomas and 14.5% for simple cysts. No statistically significant difference was observed in relation to prevalence of hemangiomas and cysts among cirrhotic and non-cirrhotic patients (p = 0.954; p = 0.472. Conclusion In the present study, the prevalence of cysts and hemangiomas was higher than the prevalence reported by autopsy series. No influence of cirrhosis was observed on the prevalence and appearance of such incidental lesions.

Evaluation of hepatic hemangioma by Tc-99 m red blood cell hepatic blood pool scan

International Nuclear Information System (INIS)

Sohn, Myung Hee

2005-01-01

Hemangioma is the most common benign tumor of the liver, with a prevalence estimated as high as 7%. Tc-99m red blood cell (RBC) hepatic blood pool scan with single photon emission computed tomography (SPECT) imaging is extremely useful for the confirmation or exclusion of hepatic hemangiomas. The classic finding of absent or decreased perfusion and increased blood pooling ('perfusion/blood pool mismatch') is the key diagnostic element in the diagnosis of hemangiomas. The combination of early arterial flow and delayed blood pooling ('perfusion/blood pool match') is shown uncommonly. In giant hemangioma, filling with radioactivity appears first in the periphery, with progressive central fill-in on sequential RBC blood pool scan. However, the reverse filling pattern, which begins first in the center with progressive peripheral filling, is also rarely seen. Studies with false-positive blood pooling have been reported infrequently in nonhemangiomas, including hemangiosarcoma, hepatocellular carcinoma, hepatic adenoma, and metastatic carcinomas (adenocarcinma of the colon, small cell carcinoma of the lung, neruroendocrine carcinoma). False-negative results have been also reported rarely except for small hemagniomas that are below the limits of spatial resolution of gamma camera

Purpose: To correlate hepatic hemangioma enhancement types in gadolinium-enhanced magnetic resonance (MR) images with diffusion-weighted MR findings and apparent diffusion coefficients (ADCs). Materials and methods: Respiratory-triggered diffusion-weighted MR images (TR/TE, 2422/46 ms; parallel imaging factor, 2; b factor, 500 s/mm{sup 2}; number of averaging, 6) obtained in 35 patients with 44 hepatic hemangiomas diagnosed by gadolinium-enhanced MR and by follow-up imaging were retrospectively evaluated. Hemangiomas were classified into three enhancement types based on gadolinium-enhanced MR imaging findings: type I, early-enhancement type; type II, peripheral nodular enhancement type; type III, delayed enhancement type. Two blinded readers qualitatively assessed lesion sizes and signal intensities on T2-weighted turbo spin-echo and diffusion-weighted images. The ADCs of hemangiomas were also measured. Results: No significant difference was observed between the three enhancement types in terms of signal intensities on T2-weighted images. Signal intensities on diffusion-weighted images were lower in the order type I to III (P < .01), and mean ADCs were 2.18 x 10{sup -3}, 1.86 x 10{sup -3}, and 1.71 x 10{sup -3} mm{sup 2}/s for types I, II, and III, respectively (P < .01). No correlation was found between lesion sizes and ADCs. Conclusion: Hepatic hemangiomas were found to have enhancement type dependent signal intensities and ADCs on diffusion-weighted MR images. Further studies will have to substantiate that these diffusion patterns might reflect intratumoral blood flow or perfusion.

Hemangioma and vascular malformations in the field of oral and maxillofacial surgery is a pathology more often found in recent years in patients. The aim of this study was to evaluate the efficacy of the laser photocoagulation performed with a diode laser (Ga-Al-As) 980 nm wavelength in the treatment of vascular lesions which are located on the oral and maxillofacial areas, using color Doppler ultrasonography for evaluation of the results. We also made a comparison between laser therapy and sclerotherapy in order to establish treatment protocols and recommendations associated with this pathology. We conducted a controlled study on a group of 92 patients (38 male and 54 female patients, with an average age of 36 years) having low flow hemangioma and vascular malformations. Patients in this trial received one of the methods of treatment for vascular lesions such as hemangioma and vascular malformations: laser therapy or sclerotherapy. After laser therapy we have achieved a reduction in size of hemangioma and vascular malformations treated with such a procedure, and the aesthetic results were favorable. No reperfusion or recanalization of laser treated vascular lesions was observed after an average follow-up of 6 to 12 months. In case of sclerotherapy a reduction in the size of vascular lesions was also obtained. The 980 nm diode laser has been proved to be an effective tool in the treatment of hemangioma and vascular malformations in oral and maxillofacial area. Laser therapy in the treatment of vascular lesions was more effective than the sclerotherapy procedure.

We report two cases of diffuse hemangioma of the colon in adolescent patients. One patient had multiple phleboliths at the lower pelvis identified with plain radiographs of the abdomen. Several aspects were seen on double-contrast enema: luminal narrowing, colonic-wall thickening and submucosal colonic masses that changed in appearance with the degree of colonic distension. Angiography was inconclusive in one case. Use of CT and MR provided relevant information regarding the true extent of the disease, but MR was superior in demonstrating unequivocally the vascular nature of the lesions. (orig.)

Giant liver hemangioma resected by trisectorectomy after efficient volume reduction by transcatheter arterial embolization: a case report

Full Text Available Abstract Introduction Liver hemangiomas are the most common benign liver tumors, usually small in size and requiring no treatment. Giant hemangiomas complicated with consumptive coagulopathy (Kasabach-Merritt syndrome or causing severe incapacitating symptoms, however, are generally considered an absolute indication for surgical resection. Here, we present the case of a giant hemangioma, which was, to the best of our knowledge, one of the largest ever reported. Case presentation A 38-year-old Asian man was referred to our hospital with complaints of severe abdominal distension and pancytopenia. Examinations at the first visit revealed a right liver hemangioma occupying the abdominal cavity, protruding into the right diaphragm up to the right thoracic cavity and extending down to the pelvic cavity, with a maximum diameter of 43 cm, complicated with "asymptomatic" Kasabach-Merritt syndrome. Based on the tumor size and the anatomic relationship between the tumor and hepatic vena cava, primary resection seemed difficult and dangerous, leading us to first perform transcatheter arterial embolization to reduce the tumor volume and to ensure the safety of future resection. The tumor volume was significantly decreased by two successive transcatheter arterial embolizations, and a conventional right trisectorectomy was then performed without difficulty to resect the tumor. Conclusions To date, there have been several reports of aggressive surgical treatments, including extra-corporeal hepatic resection and liver transplantation, for huge hemangiomas like the present case, but because of its benign nature, every effort should be made to avoid life-threatening surgical stress for patients. Our experience demonstrates that a pre-operative arterial embolization may effectively enable the resection of large hemangiomas.

Oral propranolol has been used to treat complicated infantile hemangiomas, although data from randomized, controlled trials to inform its use are limited. We performed a multicenter, randomized, double-blind, adaptive, phase 2-3 trial assessing the efficacy and safety of a pediatric-specific oral propranolol solution in infants 1 to 5 months of age with proliferating infantile hemangioma requiring systemic therapy. Infants were randomly assigned to receive placebo or one of four propranolol regimens (1 or 3 mg of propranolol base per kilogram of body weight per day for 3 or 6 months). A preplanned interim analysis was conducted to identify the regimen to study for the final efficacy analysis. The primary end point was success (complete or nearly complete resolution of the target hemangioma) or failure of trial treatment at week 24, as assessed by independent, centralized, blinded evaluations of standardized photographs. Of 460 infants who underwent randomization, 456 received treatment. On the basis of an interim analysis of the first 188 patients who completed 24 weeks of trial treatment, the regimen of 3 mg of propranolol per kilogram per day for 6 months was selected for the final efficacy analysis. The frequency of successful treatment was higher with this regimen than with placebo (60% vs. 4%, P<0.001). A total of 88% of patients who received the selected propranolol regimen showed improvement by week 5, versus 5% of patients who received placebo. A total of 10% of patients in whom treatment with propranolol was successful required systemic retreatment during follow-up. Known adverse events associated with propranolol (hypoglycemia, hypotension, bradycardia, and bronchospasm) occurred infrequently, with no significant difference in frequency between the placebo group and the groups receiving propranolol. This trial showed that propranolol was effective at a dose of 3 mg per kilogram per day for 6 months in the treatment of infantile hemangioma. (Funded by

Objective: To report the prevalence and to describe the atypical centrifugal (inside-out) appearance of contrast-enhancement of liver hemangiomas on contrast-enhanced sonography. Materials and methods: Baseline and SonoVue-enhanced ultrasonography of 92 patients with 158 liver hemangiomas - considered atypical at grey-scale examination and confirmed by computed tomography, magnetic resonance imaging and ultrasound follow-up - were reviewed in consensus by two experienced radiologists, who evaluated baseline echogenicity and the dynamic enhancement pattern of each lesion looking for the presence of central enhancing foci in the arterial phase followed by a centrifugal (inside-out) enhancement in the portal-venous and late phases. Results: After administration of SonoVue, 12/158 hemangiomas (7.6%) (size range: 1-7 cm; mean: 3.2 cm) in seven patients (5 women, 2 men; age range: 34-71 years, mean: 50.8 years) showed a central enhancing focus in the arterial phase followed by a centrifugal enhancement in the portal-venous and late phases. In all cases centrifugal enhancement was incomplete at contrast-enhanced sonography, whereas computed tomography and/or magnetic resonance imaging were able to depict a complete and homogeneous fill-in. Conclusion: Radiologist should be aware that centrifugal (inside-out) appearance on contrast-enhanced sonography is a rare but possible feature of liver hemangioma

Objective: To report the prevalence and to describe the atypical centrifugal (inside-out) appearance of contrast-enhancement of liver hemangiomas on contrast-enhanced sonography. Materials and methods: Baseline and SonoVue-enhanced ultrasonography of 92 patients with 158 liver hemangiomas - considered atypical at grey-scale examination and confirmed by computed tomography, magnetic resonance imaging and ultrasound follow-up - were reviewed in consensus by two experienced radiologists, who evaluated baseline echogenicity and the dynamic enhancement pattern of each lesion looking for the presence of central enhancing foci in the arterial phase followed by a centrifugal (inside-out) enhancement in the portal-venous and late phases. Results: After administration of SonoVue, 12/158 hemangiomas (7.6%) (size range: 1-7 cm; mean: 3.2 cm) in seven patients (5 women, 2 men; age range: 34-71 years, mean: 50.8 years) showed a central enhancing focus in the arterial phase followed by a centrifugal enhancement in the portal-venous and late phases. In all cases centrifugal enhancement was incomplete at contrast-enhanced sonography, whereas computed tomography and/or magnetic resonance imaging were able to depict a complete and homogeneous fill-in. Conclusion: Radiologist should be aware that centrifugal (inside-out) appearance on contrast-enhanced sonography is a rare but possible feature of liver hemangioma.

A painless, bluish, submucosal swelling on one side of the floor of the mouth usually indicates the presence of a ranula. Rarely, such a swelling may be caused by an inflammatory disease process in a salivary gland, a neoplasm in the sublingual salivary gland, a lymphatic nodular swelling, or embryologic cysts. We report a patient with swelling in the floor of her mouth that was clinically diagnosed as a ranula. Suspicion arose during surgery that it was a vascular tumor and, on histologic testing, the swelling was confirmed to be a hemangioma. To our knowledge, this is the first report in the literature of a hemangioma presenting as a ranula.

Full Text Available Infantile hemangiomas (IHs are the most common benign soft tissue tumor of infancy and childhood. Many patients seek early treatment to halt progression of tumor growth and accelerate regression to achieve quick resolution with good cosmetic outcomes. We reviewed literature through PubMed search on the treatment strategies for IH and share our experience in the field of laser treatment of IH. Treatment strategies for IH include both pharmacological, laser, and surgical interventions depending on the stage and severity of the lesion. Various laser beams have been attempted with varying effects and effectiveness. The 595-nm pulsed dye laser therapy has been most widely utilized owing to its great efficacy but minimal adverse effects. It works by targeting oxyhemoglobin chromophore in blood vessels located within the dermis, causing photothermal damage of these target vessels stimulating quick involution without damaging surrounding healthy skin. It is especially useful in treating ulcerated superficial facial hemangiomas that necessitate rapid healing to avoid unsightly scarring. It has a good safety profile but small risk of epidermal burn, blistering, postinflammatory pigment changes, and scarring remains in those with darker skin types treated with higher fluences and short-pulsed duration. Combination treatment with 1064 nm neodymium-doped yttrium aluminum garnet laser, oral propranolol, and even corticosteroids remains an option, especially in treatment of deep, large, and functionally threatening IH. Careful consideration in consultation with the child's parents given the complexities and potential complications surrounding treatment should always be considered. Laser treatment remains an appropriate treatment for rapidly growing IH in exposed locations at early presentation.

To investigate the clinical effect of 1% lauromacrogol for the treatment of facial refractory hemangioma and vascular malformation. From Sept 2009 to Nov 2011, 55 patients (20 male, 35 female, 1 month to 30 years) with different types of facial hemangiorwa and vascular malformation about 1.0 cm x (0. 5-5.0) cm x 10.0 cm in size, underwent 1% lauromacrogol intratumor injection therapy. Generally, the injection dose, concentration, frequency were determined by the age of the patients, the volume and depth of the lesion. The dose was limited to 10 mg every time. The injection interval is 14 weeks. After followed up for 3-16 months, 41 cases were cured, 9 cases were greatly improved, and 5 were partially improved. Skin necrosis happened in only 2 cases. Lauromacrogol is safe, simple and effective as a sderosing agent for the treatment of facial refractory hemangioma and vascular malformation. It provides a new and alternative way for the treatment of facial refractory hemangioma and vascular malformation.

The objective is to analyze the main epidemiological, pathophysiological, clinical,and imagenological aspects of the vascular hemangiomas and vascular malformations, emphasizing the therapeutic options. The vascular hemangiomas and malformations are the most frequent benign tumors in childhood. Their description and classification remain confusing, which makes it difficult to have an adequate approach to the diagnosis and their treatment. The radiologist has to guide the physician through the selection of the appropriate study for each patient, and characterize in detail all the injuries based on the analysis of the diagnostic modalities performed. The role of the interventionist radiologist is crucial as a part of the interdisciplinary group, which has to be involved in the treatment of these patients. Patients with this pathology, sent from medical assistance centers around the country are consulted at the Instituto Nacional de Cancerologia (Cancer Research National Institute). Based on this experience, it shows clinical and imagenological focus for the diagnosis and handling of these injuries.

Full Text Available Hemangiomas are developmental vascular abnormalities and more than 50% of these lesions occur in the head and neck region, with the lips, tongue, buccal mucosa, and palate most commonly involved. They are considered as hamartomas rather than true neoplasms. Here we report a case of hemangioma of the body of the tongue, discussing the diagnostic aspects and treatment modalities of such lesion and emphasizing the role of the color Doppler ultrasonography, especially in the diagnosis and treatment. Factors such as patient′s age, size and site of lesion and the proximity of lesion to vital structure are paramount in the determination of the therapeutic approach and surgical excision. Even though radiotherapy, cryotherapy, laser therapy, medical treatment, injection of sclerosing substances and the selective embolization of the lingual artery seem to have some efficacy, the author conclude that surgery is the therapy of choice in the isolated vascular lesions of the body of the tongue.

Full Text Available Resumo: Este trabalho pretende proporcionar uma visão geral sobre a problemática da lesão medular, focando essencialmente os aspectos relacionados com a reabilitação.A lesão medular atinge indivíduos jovens numa fase activa da vida, podendo condicionar graves incapacidades. Na maioria dos casos a etiologia é traumática, constituindo os acidentes de viação a sua principal causa. Até meados do século passado a sobrevivência era muito reduzida e a morte ocorria sobretudo por problemas nefro-urológicos. Com a evolução do conhecimento médico e com os meios disponibilizados pela tecnologia tem sido possível um aumento significativo da esperança de vida. Também as causas de morte sofreram alterações ao longo do tempo, sendo actualmente as complicações respiratórias, sobretudo a pneumonia, a primeira causa.No quadro clínico da lesão medular podemos considerar uma fase inicial de choque medular, em que existe uma paralisia flácida e retenção urinária e fecal; progressivamente iniciase a fase de automatismo medular com retorno de algumas actividades reflexas da medula Através do exame neurológico é possível muito precocemente estabelecer o prognóstico motor e funcional e planificar o programa de reabilitação. Podemos considerar três fases no programa de reabilitação: a primeira, corresponde ao período de acamamento para estabilização cirúrgica e médica da lesão esquelética, sendo fundamental prevenir ou tratar as complicações relacionadas com a imobilidade e iniciar a reeducação dos esfíncteres; na segunda, pretende-se atingir a funcionalidade ao nível de cadeira de rodas; a terceira fase consiste no treino em ortostatismo. O programa de reabilitação engloba ainda actividades desportivas e recreativas, bem como o acompanhamento psicológico e social para uma abordagem global da les

Infantile hemangiomas (IH) are common tumors for which there is no validated disease-specific instrument to measure the quality of life in infants and their parents/caregivers during the critical first months of life. This study prospectively developed and validated a quality-of-life instrument for patients with IH and their parents/caregivers and correlated demographic and clinical features to the effects on the quality of life. A total of 220 parents/caregivers completed the 35-item Infantile Hemangioma Quality-of-Life (IH-QoL) instrument and provided demographic information. The dimensionality of the items was evaluated using factor analysis, with results suggesting four factors: child physical symptoms, child social interactions, parent emotional functioning, and parent psychosocial functioning. Each factor fit the Rasch measurement model with acceptable fit index (mean square instrument consists of four scales with a total of 29 items. Content validity was verified by analyzing parents' responses to an open-ended question. Test-retest reliability at a 48-hour interval was supported by a total IH-QoL intraclass correlation coefficient of 0.84. Certain clinical characteristics of hemangioma, including those located on the head and neck, in the proliferative stage, and requiring treatment, are associated with a greater impact on QoL.

Full Text Available A seven-year-old male Scottish terrier was examined at the Veterinary Hospital of the Universidade Estadual de Londrina due to a toracolumbar syndrome classified as V degree and a mass in lumbar region back right of slow growth with evaluation of two months. Myelography showed an interruption of the column of contrast between the 11th and 12th thoracic vertebrae. A hemilaminectomy was performed in this region. Spinal cord compression at this location was not observed, however during the caudal enlargement of hemilaminectomy it was visualized in the region of the fourth lumbar vertebrae, a spinal cord deviation to the left, due to the presence of a reddish mass at the right side that was diagnosed as a tumor infiltration in the vertebrae with cord compression. Surgical removal with appropriate margin was not possible. In histology, the tumor was classified as hemangiosarcoma. This report emphasizes the importance of considering the possibility of cancer as differential diagnosis of paraplegias, even in acute clinical changes.Um cão macho, Scottish Terrier, de sete anos foi atendido no Hospital Veterinário da Universidade Estadual de Londrina por apresentar paraplegia grau V e um nódulo em região dorso lombar direita de crescimento lento, com evolução de dois meses. Foi realizado mielografia, visibilizando-se interrupção na coluna de contraste entre as vértebras torácicas 11ª e 12ª. Assim, procedeu-se à hemilaminectomia nesta região, não sendo constatado compressão medular, procedendo-se a ampliação caudal da abertura da lâmina vertebral T12. Na região da quarta vértebra lombar observou-se um desvio da medula espinhal para o lado esquerdo devido à presença de uma massa de coloração avermelhada proveniente do lado direito, diagnosticando-se infiltração tumoral em vértebras com compressão medular, não sendo possível sua remoção cirúrgica. Na histologia classificou-se o tumor como hemangiossarcoma. Este relato

Full Text Available In pregnancy, advanced vertebral hemangiomas may be seen, and these require treatment. The case reported here is of a 35-year-old female in the 32nd week of pregnancy who was admitted to the orthopaedics clinic with a history of backache and difficulty walking. A burst fracture of L1 associated with a vertebral hemangioma was identified with an L3 compression fracture secondary to osteoporosis. The local kyphosis angle between T12 and L2 was 27°. Kyphotic deformity was corrected and postoperatively, the measured T12–L2 local kyphotic angle was 9°. Twelve hours postoperatively, oral nutrition was allowed, but she developed nausea and vomiting and twenty-four hours postoperatively, an electrolyte imbalance developed. Postoperatively, the patient was diagnosed with superior mesenteric artery syndrome. To the best of our knowledge, this is the first reported case of superior mesenteric artery syndrome, which occurred following the correction of a kyphotic deformity that had developed secondary to an advanced hemangioma in pregnancy.

MÉTODOS: Foram avaliados 170 pacientes com diagnóstico de paraplegia e tetraplegia, em três etapas - levantamento de dados em prontuário, entrevista oral e avaliação do padrão do nado. Os resultados apontaram que grande parte dos pacientes não entrou na piscina ou realizou nado após a lesão medular. A avaliação da adaptação ao meio líquido após a lesão medular demonstrou que grande parte dos pacientes realizou a imersão e flutuação de forma independente, porém, apresentando dificuldade em mudar de decúbito dentro da água. Apenas uma pequena porcentagem retomou a natação após a lesão medular; foi também verificada redução no total dos sujeitos que nadavam regularmente antes. A avaliação apontou que os nados crawl e de costas foram realizados por metade dos avaliados; apenas uma pequena parte realizou nado de peito. CONCLUSÃO: Após a avaliação dos relatos dos pacientes, verificou-se redução na prática da natação, seja como atividade esportiva, física ou de lazer após a lesão medular, apesar de a aptidão para o nado não ter sofrido grandes alterações.Pysical activity, particularly swimming, that brings a lot of benefits to subjects with spinal cord injury, can be started during rehabilitation.

Full Text Available Mucocutaneous lesion appears in up to 40% of patients with primary systemic amyloidosis (AL amyloidosis. The cutaneous signs may be co-expressed with other organ involvement or even solely presented as the first clue. We reported a case of systemic AL amyloidosis who was initially presented as a solitary hemangioma with a purpuric halo. Excisional biopsy revealed a hemangioma with amyloid deposited in thickened vascular walls. Systemic AL amyloidosis was diagnosed after thorough survey. The stage of disease at the time of initial treatment is the greatest prognostic factor. To our knowledge, this is the first case of systemic AL amyloidosis initially presented as a purpuric halo around hemangioma in Taiwan. This target-like lesion should be linked to systemic AL amyloidosis and early diagnosis is extraordinary important.

Nasal glial heterotopia or congenital hemangioma? A case report.

Lartizien, R; Durand, C; Blaise, S; Morand, B

2017-10-01

Nasal glial heterotopia (NGH) is a rare benign tumor of the median line. We describe the case of a child presenting a lateral nasal mass. The characteristics of the prenatal ultrasound and the postnatal clinical examination argued in favor of a congenital hemangioma (CH). The MRI performed at 6 weeks of life suggested glial heterotopia. This diagnosis was confirmed by the pathological analysis. Congenital hemangiomas and nasal glial heterotopies have similar clinical presentations. Prenatal ultrasound diagnosis between NGH and CH is difficult. Fetal MRI is not yet highly specific for these two lesions, but it can eliminate an intracerebral connection in cases of NGH. Postnatal exams are more specific. Flow on the Doppler exam is rapid for CH and slow for NGH. On MRI, these two lesions appear as a hypersignal on T2-weighted sequences, but less intense for NGH than for CH. Distinguishing between NGH and CH can be difficult. This does not have a direct incidence on treatment because it is surgical in both cases. Copyright © 2017 Elsevier Masson SAS.

Full Text Available Intraosseous hemangioma is a rare bone tumor accounting for 0.7%–1.0% of all bone tumors. In the skull, frontal bone is the commonly involved bone. An 8-year-old female presented to our outpatient department with complaints of pain and swelling over forehead for 4 months. X-ray revealed a lytic expansile lesion involving frontal bone with sunburst pattern of bony spicules radiating to periphery of the lesion. Magnetic resonance imaging revealed the presence of a well-circumscribed lesion with both intra as well as extracranial components. Histopathology revealed a vascular tumor consisting of both small (capillary and large (cavernous sized vessels. A diagnosis of mixed type of hemangioma of the frontal bone was given. Recognition of hemangioma on radiology and confirmation by histopathology is essential for proper management as it might be confused clinically with other locally aggressive/malignant lesions.

We report a rare case of congenital tri-cavernous hemangiomas of the right buccal region, right accessory parotid gland, and masseter muscle region in an adult. The patient, a 25-year-old woman, complained of 3 masses in her right midcheek. Ultrasonographic and computed tomographic findings showed an irregular-shaped mass (multiple calcifications) with a well-defined margin in the masseter muscle region, an ellipse-shaped mass (multiple calcifications) with a well-defined margin in the right buccal region, and a comma-shaped mass (no calcifications) with a well-defined margin separate from the parotid gland in the right accessory parotid gland region. These iconographic findings suggested that the masses were all hemangiomas separately originating from the parotid gland, accessory parotid gland, and masseter muscle. The masses were completely removed through a standard parotid incision without postoperative facial palsy, skin deformity, and difficulty in secreting saliva. Findings from histologic examination of the tumor revealed multiple, thin-walled, and dilated blood vessels, confirming the diagnosis of cavernous hemangiomas. Ultrasonographic and computed tomographic findings were extremely useful in diagnosing the mass/masses as hemangioma before surgery, clarifying relationships between the mass and adjacent structures, and determining the surgical approach to the mass/masses.

Full Text Available Abstract Introduction Cavernous hemangiomas of the uterus are rare benign vascular lesions. Nine cases of diffuse cavernous hemangioma of the gravid uterus have been reported, most of which diffusely involved the myometrium. These vascular malformations are clinically significant, and may cause pronounced bleeding resulting in maternal or fetal demise. Thrombosis of cavernous hemangiomas of the uterus has been previously reported. We here report the first case in which a thrombosed cavernous hemangioma of the myometrium resulted in a fatal pulmonary embolism in a post-partum woman. Case presentation A 25-year-old obese African-American woman who had one pregnancy and was delivered of twins by cesarean section was admitted 1 week after the successful delivery. The 12-day clinical course included ventilator-dependent respiratory failure, systemic hypertension, methicillin-resistant Staphylococcus aureus in the sputum, leukocytosis and asystole. A transabdominal ultrasound examination showed heterogeneous thickened and irregular products in the endometrial canal. The laboratory values were relevant for an increased prothrombin time, activated partial thromboplastin time, ferritin and a decrease in hemoglobin. The clinical cause of death was cited as acute respiratory distress syndrome. At autopsy, a 400g spongy, hemorrhagic uterus with multiple cystic spaces measuring approximately 0.5 × 0.4cm filled with thrombi within the myometrium was identified. Immunohistological examination with a CD31 stain for vascular endothelium associated antigen confirmed several endothelium-lined vessels, some of which contained thrombi. These histological features were consistent with cavernous hemangioma of the myometrium. A histological examination of the lungs revealed multiple fresh thromboemboli in small- and medium-sized pulmonary arteries in the right upper and lower lobes without organization, but with adjacent areas of fresh hemorrhagic infarction

Full Text Available A lesão medular é incapacitante, irreversível e de custo econômico e social elevado. Neste estudo, objetivou-se padronizar um modelo de lesão medular, que produza paraplegia, com o uso de cateter e avaliar histologicamente a efetividade da lesão para estudos com terapia celular. Foram realizadas as lesões medulares em ratos Wistar, utilizando-se o cateter Fogarty n.3 e compressão na região toracolombar (T8-T9 durante 5 minutos. Foram estudados três grupos: grupo A, animais controle sem lesão medular; grupo B, animais submetidos à lesão, utilizando-se 50µL de compressão; grupo C, animais submetidos à lesão, utilizando-se 80µL de compressão. Foi realizada avaliação motora pela aplicação da escala BBB, antes da compressão, após recuperação anestésica, 24 e 72 horas depois da compressão e sete dias após a compressão. Após o sétimo dia da lesão, os animais foram submetidos à eutanásia, foi feita a retirada da medula espinhal, fígado e rins e realizada a análise histológica com a coloração hematoxilina-eosina. A mortalidade variou entre os grupos, com 0% no grupo A, 38,5% no B e 48% no C. Nesses dois últimos grupos, a causa da morte foi edema pulmonar neurogênico, confirmado clínica e histologicamente. As medulas espinhais histologicamente apresentaram diferentes graus de edema, congestão vascular e hemorragia, enquanto que os fígados e os rins apresentaram diferentes graus de congestão vascular e necrose. Em relação à recuperação dos movimentos, no grupo A, verificou-se 100% de escore 21; no B, 25% de escore 21; 37,5% de escore 11; e 37,5% de escore 0; enquanto, no grupo C, verificou-se 100% de escore 0. Conclui-se que o procedimento realizado utilizando-se 80µL de solução salina para preencher o balão do cateter foi mais eficiente, apesar de maior mortalidade, pois apresentou maior porcentagem de animais com lesão completa (paraplegia.

Background and purpose: A cohort study was performed to investigate the carcinogenic effect of treating skin hemangioma with ionizing radiation during early childhood. This paper presents the incidence of differentiated thyroid adenomas and carcinomas after radiotherapy in this cohort. Methods and materials: Of a total of 8307 patients treated for a skin hemangioma between 1940 and 1973 at the Institut Gustave-Roussy, 4767 were included in an incidence study, among whom 3795 had received radiotherapy. Seventy-three percent were less than 1-year-old at the time of treatment. External radiotherapy, Radium 226, Strontium 90, Yttrium 90, and Phosphorus 32 were used. The radiation dose received by the thyroid during radiotherapy, estimated in 3497 of the 3795 patients using specific software, was 41 mGy on average. Thyroid tumor cases were obtained by sending out a questionnaire, and were verified in pathological reports. Estimates of thyroid cancer specific incidence rates in the French population were obtained from the French cancer registry network. External and internal analyses were performed. Results: During an average follow-up of 35 years, 11 patients developed a differentiated thyroid carcinoma and 44 a thyroid adenoma. The incidence of thyroid adenoma was found to be higher among taller and heavier individuals. The incidence of both thyroid carcinoma and adenoma was higher among non-smoker patients. A significant dose-response relationship was found between the radiation dose received by thyroid and the risk of thyroid cancer (Excess Relative Risk per GY, ERR/Gy: 14.7, 95%CI: 1.6-62.9) and of adenoma (ERR/Gy: 5.7, 95%CI: 0.7-19.4). Conclusion: This study confirms that radiation treatment performed in the past for hemangioma during infancy increased the risk of thyroid carcinoma and adenoma. Patients treated with external radiotherapy or with Radium 226 applicators for hemangiomas have to be more specifically followed up because this is the subgroup in whom the

Topical application of timolol cream is effective and convenient for treating superficial infantile hemangiomas. Intralesional injection of corticosteroids, such as diprospan, is useful for the treatment of superficia infantile hemangiomas without systemic side effects. We conducted a self-controlled study to investigate whether a combination of intralesional injection of diprospan with topical timolol 0.5% cream would be more efficient than timolol cream alone in thick superficial infantile hemangiomas. Thirty-eight patients with 39 thick superficial infantile hemangiomas were recruited. Each lesion was randomly divided into two equal parts: one part was treated with topical timolol 0.5% cream (timolol cream group), while the other part was treated with injection of diprospan combined with topical timolol 0.5% cream (combined treatment group). Infants were followed every 4 weeks to determine whether injections should be continued, and timolol cream was applied four times daily for 5 months. During 5 months of treatment, three specialist physicians were invited to evaluate the therapeutic effects. The combined treatment group showed better lesion involution than did the timolol cream group regarding lesion thickness and color of lesions. The combination of intralesional injection of diprospan with topical timolol 0.5% cream is a suitable and safe strategy for thick superficial infantile hemangiomas. © 2018 Wiley Periodicals, Inc.

The aim was to compare high-resolution computed tomography (HRCT) and thin-section magnetic resonance imaging (MRI) findings of facial nerve hemangioma. The HRCT and MRI characteristics of 17 facial nerve hemangiomas diagnosed between 2006 and 2013 were retrospectively analyzed. All patients included in the study suffered from a space-occupying lesion of soft tissues at the geniculate ganglion fossa. Affected nerve was compared for size and shape with the contralateral unaffected nerve. HRCT showed irregular expansion and broadening of the facial nerve canal, damage of the bone wall and destruction of adjacent bone, with "point"-like or "needle"-like calcifications in 14 cases. The average CT value was 320.9 ± 141.8 Hu. Fourteen patients had a widened labyrinthine segment; 6/17 had a tympanic segment widening; 2/17 had a greater superficial petrosal nerve canal involvement, and 2/17 had an affected internal auditory canal (IAC) segment. On MRI, all lesions were significantly enhanced due to high blood supply. Using 2D FSE T2WI, the lesion detection rate was 82.4 % (14/17). 3D fast imaging employing steady-state acquisition (3D FIESTA) revealed the lesions in all patients. HRCT showed that the average number of involved segments in the facial nerve canal was 2.41, while MRI revealed an average of 2.70 segments (P facial nerve hemangioma were typical, revealing irregular masses growing along the facial nerve canal, with calcifications and rich blood supply. Thin-section enhanced MRI was more accurate in lesion detection and assessment compared with HRCT.

Full Text Available Abstract Background Cavernous hemangiomas are the most frequent neoplasms of the liver and in routine clinical practice they often need to be differentiated from malignant tumors and other benign focal lesions. The purpose of this study is to evaluate whether diagnostic accuracy of magnetic resonance imaging (MRI of hepatic hemangiomas, showing atypical pattern on US, improves with the use of Gd-BOPTA in comparison with contrast-enhanced multi-phase computed tomography (CT. Methods 178 consecutive patients with ambiguous hepatic masses showing atypical hyperechoic pattern on grey-scale US, underwent unenhanced and contrast-enhanced multi-phase multi-detector CT and MR (1.5T with the use of liver-specific contrast medium gadobenate dimeglumine (Gd-BOPTA. After intravenous contrast administration arterial (HAP, venous-portal (PVP, equilibrium phases (EP both in CT and MR and additionally hepatobiliary phase (HBP in MR were obtained. 398 lesions have been detected including 99 hemangiomas and 299 other lesions. Results In non-enhanced MDCT examination detection of hemangiomas was characterized by sensitivity of 76%, specificity of 90%, PPV of 71%, NPV of 92% and accuracy of 86%. Non-enhanced MR examination showed sensitivity of 98%, specificity of 99%, PPV of 99%, NPV of 99% and accuracy of 99%. After intravenous administration of contrast medium in MR the mentioned above parameters did not increase significantly. Conclusion Gd-BOPTA-enhanced MR in comparison with unenhanced MRI does not improve diagnostic accuracy in discriminating hemangiomas that show non-specific appearance in ultrasound examination. Unenhanced MR as a method of choice should directly follow US in course of diagnostic algorithm in differentiation of hemangiomas from other liver tumors.

Kasabach-Merritt syndrome (KMS) consists of thrombocytopenia, microangiopathic hemolytic anemia, and localized consumption coagulopathy that develops within vascular hemangioma. This syndrome may also be associated with occult hemangiomas located at various sites. Tc-99m RBC scintigraphy and SPECT have proven to be reliable for confirming or excluding hemangioma. Total body blood pool imaging study during the scintigraphy also provides a means of screening for occult lesions. The authors report the case of a 29-year-old man who presented with a giant hepatic hemangioma complicated by KMS, and underwent Tc-99m RBC scintigraphy and SPECT including a total body blood pool imaging study.

Objective: to establish the role of MRI T2-weighted sequences in the differentiation between simple cysts and hepatic hemangiomas. Materials and methods: a double-blinded, prospective, observational, cross sectional study evaluated 52 patients with 91 hepatic lesions (34 simple cysts and 57 hemangiomas) submitted to abdominal magnetic resonance imaging. The combined analysis of all sequences was considered as the golden-standard. TSE sequences with long echo trains and b-FFE sequences were subjectively analyzed by two independent observers for differentiating cysts from hemangiomas. The kappa test (κ) was utilized in the analysis of the methods accuracy and inter- and intra-observer agreement (p * ). Results: cysts and hemangiomas dimensions ranged respectively between 0.5 and 6.5 cm (mean 1.89 cm), and 0.8 and 11 cm (mean = 2.62 cm). The analysis of the sequences with long-TE and the golden-standard demonstrated a non-statistically significant agreement (k: 0.00-0.10). The agreement between the evaluation of the b-FFE sequence and the golden-standard ranged from substantial (κ: 0.62-0.71) to almost perfect (κ: 0.86) for both observers. The inter- and intra-observer agreement for the b-FFE sequence ranged from substantial (κ: 0.62-0.70) to almost perfect (κ: 0.85-0.91). Conclusion: T2-weighted images acquired with the b-FFE technique present a high accuracy and reproducibility in the differentiation between cysts and hepatic hemangiomas. (author)

The aim of this study is to describe vision loss caused by central retinal artery and posterior ciliary artery occlusion as a consequence of sclerotherapy with a polidocanol injection to a glabellar hemangioma. An 18-year-old man underwent direct injection with a 23-gauge needle of 1 mL of a polidocanol-carbon dioxide emulsion into the glabellar subcutaneous hemangioma under ultrasound visualization of the needle tip by radiologists. He developed lid swelling the next day, and 3 days later at referral, the visual acuity in the left eye was no light perception. Funduscopy revealed central retinal artery occlusion and fluorescein angiography disclosed no perfusion at all in the left fundus, indicating concurrent posterior ciliary artery occlusion. The patient also showed mydriasis, blepharoptosis, and total external ophthalmoplegia on the left side. Magnetic resonance imaging demonstrated the swollen medial rectus muscle. In a month, blepharoptosis and ophthalmoplegia resolved but the visual acuity remained no light perception. Sclerosing therapy for facial hemangioma may develop a severe complication such as permanent visual loss.

A case of a patient with hepatic hemangioma was studied by non-invasive methods. Ultrasonography (US) and computed tomography (CT) studies were able to detect some lesions, but not ascertain the diagnosis. Planar scintigraphy both with 99m Tc-sulfur colloid and with in vivo labelled RBC's did not show the lesions, while single-photon emission tomography (blood pool and sulfur colloid) pointed out their presence and allowed to achieve a correct diagnosis for the biggest lesion (2.5 cm in diameter)

Small liver hemangiomas are displayed as echogenic as well as sonolucent patterns on ultrasonic scans. Differentiation from malignomas is difficult and responsible, hepatomas and solitary metastases being possible. By partial liver resection the malignant diseases can be treated successfully. Therefore an accurate diagnosis is to be aimed at. Of all the methods only angiography can ensure a certain amount of clarity. This is possible under the following circumstances: The cavernomas must be of a certain size. They must not withdraw from evidence due to large avascular areas which can result from thrombosis, fibrosis or necrosis. Moreover a superselective filling of the hepatic artery is claimed but not always possible. If the portal vein is opacified it conceals the radiologically typical image of the cavernoma. Under these circumstances only few moments of the late arterial and the hepatovenous phases remain to detect the hemangioma in the seriogram. (orig.) [de

2006-01-01

Objective: To evaluate MRI and the color Doppler ultrasound in the diagnosis of cavernous hemangioma of liver. Methods: In total 58 patients with hemangioma of liver underwent dynamic enhanced MRI and the color Doppler ultrasound examination. The imaging manifestations obtained by both modalities were comparatively studied. Result: Highly echoic lesions were revealed in 36 cases out of 58; low echoic lesions were noted in 8; and in 14 cases the tumors were of mixed echoic. On T 1 WI the lesions were hypo- or slightly hypo-intense; while on T 2 WI they were hyper- or slightly hyper-intense. The nidi were hyper-intense on T 2 WI of CRE array. On enhanced scan the lesions were quickly fully enhanced in 25 cases out of 58. Peripheral nodular enhancement was seen in 19 cases, and centered spreading enhancement was demon- strated in 14 cases. On delayed scan remarkable homogenous enhancement was observed in all cases. Conclusion: The bigger size has the hemangioma, the smaller highly echoic proportion and bigger mixed echoic or poorly echoic proportion will be found within the lesions. More peripheral nodular enhancement will be revealed on enhanced MRI scan when the tumor size is getting larger, in which the proportion of quickly fully enhancement will decrease gradually. Ultrasound is better than MRI in the evaluation of the liver hemangioma smaller than 3 cm in diameter. MRI is superior to color Doppler ultrasound in diagnosing the lesion larger' than 3 cm in diameter. (authors)

2008-01-01

Percutaneous intervention is one treatment option for symptomatic hepatic hemangioma in infants. We report the case of a newborn (birth weight 4060 g) with a large hepatic cavernous hemangioma, which presented early with high cardiac output failure due to arteriovenous shunting and signs of incipient Kasabach-Merritt syndrome. We performed a successful superselective transcatheter coil embolization of three feeding arteries on the seventh day of life. Because of remaining diffuse very small arteries causing a relevant residual shunt, additional occlusion of the three main draining veins was necessary with three Amplatzer vascular plugs. Cardiac failure resolved immediately. Without any additional therapy the large venous cavities disappeared within the following months. The tumor continues to regress in size 8 months after the intervention

Full Text Available Las gliadinas son proteínas del trigo que desempeñan un papel central en la formación del gluten, ya que son las responsables de la viscosidad de la red. Pese a su importancia han sido menos estudiadas que las gluteninas, debido a que sus inusuales propiedades de solubilidad e hidrofobicidad dificultan su caracterización. Los objetivos de este trabajo fueron estudiar el perfil proteico de las gliadinas de cultivares de trigos argentinos mediante electroforesis capilar, y evaluar la capacidad de esta técnica para discriminar entre los diferentes cultivares. Para ello se trabajó con 12 cultivares de trigo de las diferentes categorías de calidad asignadas por el INTA, a los que se caracterizó en cuanto a su composición y calidad tecnológica y se les extrajo las gliadinas para estudiarlas por electroforesis capilar. Los resultados obtenidos confirman el potencial de esta técnica para lograr separaciones de gliadinas, con la ventaja de requerir poca preparación y poca cantidad de la muestra analizada y sencillos protocolos de limpieza y mantenimiento de capilar, permitiendo el análisis de gran cantidad de muestras. Asimismo, se demostró la capacidad de la electroforesis capilar para discriminar diferentes cultivares sobre la base de su perfil de gliadinas, lo que permite la diferenciación de genotipos.Gliadins are a group of wheat proteins that play a major role in gluten development since they account for net viscosity. Despite this fact, gliadins have not been studied as deeply as glutenins because of their unusual solubility properties and their high hydrophobicity. The objectives of this work were to study the gliadin profile of Argentinean wheats comprising a broad quality range by means of capillary electrophoresis and to assess the suitability of this technique for wheat cultivar discrimination. For this purpose, chemical compositions of twelve wheat cultivars belonging to different quality groups were determined. Besides, flour

Full Text Available Chylous ascites is rare in clinical practice. It is characterized by milky-appearing peritoneal fluid with a triglycerides concentration of >1.25 mmol/l (110 mg/dl. Its pathophysiology is related to a disruption in the normal lymphatic flow. It is more common after trauma (including post surgery, neoplasia or atypical infections such as tuberculosis or filariasis. Other rare medical causes have been reported. The treatment is supportive and focused on correction of the underlying pathology. We report here the first case of chylous ascites caused by giant liver hemangioma and discuss the management of this condition.

Two cases of rare adrenal cavernous hemangiomas are reported, one imaged with conventional X-ray techniques, US, CT, and MRI, and the other with US and CT. The CT technique clearly demonstrated calcifications and the internal structure of the lesions in both cases and peripheral rim enhancement on the postcontrast scan in one patient. Although MRI demonstrated accurately the complex nature of the lesion, the inability to visualize the calcified areas do not allow to make a specific histologic diagnosis. (orig.). With 8 figs

Full Text Available A 75-year-old Japanese woman presented with a juxtapapillary retinal capillary hemangioma (RCH in her left eye. Twelve months after the initial examination, the size of the hemangioma had increased and the exudation from the RCH involved the macula. Her best-corrected visual acuity (BCVA had decreased from 0.8 to 0.3. A total of five intravitreal injections of bevacizumab (IVB; 1.25 mg was given but the RCH did not respond. A photodynamic therapy (PDT was done using multiple laser spots to avoid damaging the optic nerve head. After the first PDT, the subfoveal fluid was reduced but not completely gone. One week after the second PDT, a massive subretinal hemorrhage developed. The subretinal hemorrhage was successfully displaced by injecting intraocular sulfur hexafluoride (SF6 gas. At the 3-year follow-up examination, no subretinal hemorrhage or fluid was observed at the macula and the BCVA remained at 0.05. Our case was resistant to the combination of anti-vascular endothelial growth factor (VEGF and PDT and had a rare massive subretinal hemorrhage. A further collection of RCH cases treated with anti-VEGF and PDT that would justify this treatment is necessary.

This is a report of case with the extracerebral cavernous hemangioma in the middle fossa in which total removal was carried out after radiotherapy. Follow-up study with computed tomography during and after irradiation are presented. A 44-year-old house-wife complained of a decreased vision of the both eyes and paresis of the left upper and lower limbs. CT scan revealed a slightly high density area in the right middle cranial fossa which was markedly enhanced with contrast media. Right carotid angio-graphy demonstrated a large avascular mass in the right middle fossa and no feeding artery or draining vein was visualized except a faint irregular stain in the venous phase. An attempt to total removal of the tumor had failed to success because of extensive hemorrhage from the tumor. Histological examination revealed a cavernous hemangioma. Irradiation with a total dose of 5000 rads was delivered. After irradiation. CT scan revealed a marked decrease of size and EMI number of the tumor. At this stage, hypervascular mass lesion with feeding arteries was noted in conventional angiography. Tumor stain in prolonged injection angiography was also visualized. In the second operation, removal of the tumor was performed without any difficulty and hemorrhage was controlled easily by electrocoagulation. Histology revealed a marked narrowing of vessels with an increase in the connective tissues. In the central part of specimen, there noted findings of coagulation necrosis, intraluminal thrombus formations and so on, which were attributed to the influence of radiation. It is concluded that in case of a extracerebral cavernous hemangioma with massive hemorrhage, radiation of up to 3000 - 5000 rads was a method of choice. The treatment results in an increase of probability of total removal of the tumor. (author)

Full Text Available A precise prenatal diagnosis of hemangioma may be uncertain although a variety of the antenatal appearances on 2-dimensional sonography have been reported. A 27-year-old primigravida was referred at 32 weeks of gestation for evaluation of a fetal nuchal mass. Two-dimensional sonography showed an extracranial mixed echogenic mass (65 × 54 × 59 mm occupying the posterior neck. Color Doppler imaging revealed intense hypervascularization. Three-dimensional (3D and 4-dimensional (4D sonography showed that the mass was lobulated, with a lumpy internal structure. Nuchal hemangioma was further confirmed by clinical examination and postnatal magnetic resonance imaging. The tumor began to regress in size when the infant was 7 months old. Prenatal 3D/4D ultrasound techniques could be considered as complementary diagnostic tools for such a tumor. They have the advantages of providing accurate and inexpensive virtual reality images through more realistic interactions with the virtualized in utero condition.

Background. Infantile hemangiomas (IHs) are the most common benign tumours of infancy. Propranolol has recently been reported to be a highly effective treatment for IHs. This study aimed to evaluate the efficacy and side effects of propranolol for treatment of complicated cases of IHs. Patients and Methods. This prospective clinical study included 30 children with huge or complicated IHs; their ages ranged from 2 months to 1 year. They were treated by oral propranolol. Treatment outcomes were clinically evaluated. Results. Superficial cutaneous hemangiomas began to respond to propranolol therapy within one to two weeks after the onset of treatment. The mean treatment period that was needed for the occurrence of complete resolution was 9.4 months. Treatment with propranolol was well tolerated and had few side effects. No rebound growth of the tumors was noted when propranolol dosing stopped except in one case. Conclusion. Propranolol is a promising treatment for IHs without obvious side effects. However, further studies with longer follow-up periods are needed.

Laparoscopic major hepatectomy remains a challenging procedure [1, 2]. In the case of giant tumors in the right liver, conventional approach (complete mobilization of the right liver before parenchymal transection) could be dangerous during mobilization because of large volume and weight [3, 4]. We present the case of a pure laparoscopic right hepatectomy for a giant hemangioma using an anterior approach. We achieved the informed consent with this patient and approved by the Ethics Committee of the Asan Medical Center. Giant hemangioma (13 × 11 × 14 cm) was located in right liver. After glissonean approach [5], Pringle maneuver was performed during the hepatic parenchymal transection. For the transection, the Cavitron Ultrasonic Surgical Aspirator was used. Small hepatic vein branches along the middle hepatic vein and small glissonean pedicles were sealed and divided with a THUNDERBEATTM (Olympus), which is the device with integration of both bipolar and ultrasonic energies delivered simultaneously. iDriveTM Ultra Powered Stapling device (Medtronic) was used for division of right glissonean pedicle and large hepatic veins. Hemangioma was removed through the lower abdominal transverse incision using the endo-bag. This technique has the advantage of avoiding excessive bleeding caused by avulsion of the hepatic vein and caval branches, iatrogenic tumor rupture [3]. By means of the anterior approach, pure laparoscopic right hepatectomy was performed successfully without intraoperative complications and transfusions. The operation time was 202 min, and the estimated blood loss was less than 150 ml. On postoperative day 3, computed tomographic scan showed no pathological findings. The patient was discharged on postoperative day 5 without complications. Laparoscopic approach has good results because of the view with magnification enabling meticulous hemostasis and the small wounds that give patients less pain [6, 7]. The authors recommend that the laparoscopic

2015-01-01

Purpose: To investigate the potential utility of in-line phase-contrast imaging (ILPCI) technique with synchrotron radiation in detecting early hepatocellular carcinoma and cavernous hemangioma of live using in vitro model system. Methods: Without contrast agents, three typical early hepatocellular carcinoma specimens and three typical cavernous hemangioma of live specimens were imaged using ILPCI. To quantitatively discriminate early hepatocellular carcinoma tissues and cavernous hemangioma tissues, the projection images texture feature based on gray level co-occurrence matrix (GLCM) were extracted. The texture parameters of energy, inertia, entropy, correlation, sum average, sum entropy, difference average, difference entropy and inverse difference moment, were obtained respectively. Results: In the ILPCI planar images of early hepatocellular carcinoma specimens, vessel trees were clearly visualized on the micrometer scale. Obvious distortion deformation was presented, and the vessel mostly appeared as a ‘dry stick’. Liver textures appeared not regularly. In the ILPCI planar images of cavernous hemangioma of live specimens, typical vessels had not been found compared with the early hepatocellular carcinoma planar images. The planar images of cavernous hemangioma of live specimens clearly displayed the dilated hepatic sinusoids with the diameter of less than 100 microns, but all of them were overlapped with each other. The texture parameters of energy, inertia, entropy, correlation, sum average, sum entropy, and difference average, showed a statistically significant between the two types specimens image (P<0.01), except the texture parameters of difference entropy and inverse difference moment(P>0.01). Conclusion: The results indicate that there are obvious changes in morphological levels including vessel structures and liver textures. The study proves that this imaging technique has a potential value in evaluating early hepatocellular carcinoma and cavernous

Full Text Available Lobular capillary hemangioma (LCH is a benign proliferation of capillary blood vessels adopting a lobular configuration. A laryngeal origin of LCH is exceedingly rare. Here, we describe a case of an 11-year-old boy presenting with a subglottic lesion, leading to a subglottic stenosis. Histopathologic findings of the lesion implicated an LCH, which was removed successfully by a coblator. This is the first report of a subglottic LCH. Physicians should be aware of this unique lesion and laryngeal LCH should be considered in diagnosing the cause of a subglottic stenosis. Additionally, coblation should be an effective treatment for laryngeal LCH.

The cavernous hemangioma is a rare benign vascular tumor. About 50 cases of this disease were found in the literature over the last century and only 9 cases of cavernous hemangioma on the pregnant uterus were published it comes into cavernous or capillary form. The symptomatology is not unequivocal and when it occurs during pregnancy or postpartum, it causes life-threatening cataclysmic hemorrhage. Antenatal diagnosis is difficult and requires a multidisciplinary approach with pathologists, radiologists and gynecologists to avoid these complications or unnecessary hysterectomies. The diagnosis is histological. Hysterectomy is possible after failure of conservative treatment means. We report a rare case, a novel mixed cavernous hemangioma of the body associated with a capillary hemangioma of the cervix in a patient of 28 years 5th visors with recurrent genital bleeding in the postpartum period leading to a hysterectomy.

Hemangiomas are common vascular tumors occurring in children. Though most of the lesions present in infants and young children with a typical appearance, it is important to understand that they all do not behave in the same way. Rather, they are a group of vascular lesions with different clinico-pathological subtypes, with their clinical behavior varying with the stage of the tumor as well. As such, they can and do have a varied clinical, imaging and pathological appearance according to the location of the tumor and also the stage at which the patient is seen. In this pictorial essay, the classification, pathogenesis, clinical appearance, natural history and imaging characteristics of hemangiomas are reviewed and illustrated. (orig.)

Full Text Available INTRODUÇÃO: O treino locomotor com suporte de peso corporal (TLSP é utilizado há aproximadamente 20 anos no campo da reabilitação em pacientes que sofrem de patologias neurológicas. O TLSP favorece melhoras osteomusculares, cardiovasculares e psicológicas, pois desenvolve ao máximo o potencial residual do organismo, proporcionando a reintegração na convivência familiar, profissional e social. OBJETIVO: Identificar as principais modalidades de TLSP e seus parâmetros de avaliação com a finalidade de contribuir com o estabelecimento de evidências confiáveis para as práticas reabilitativas de pessoas com lesão medular. MATERIAIS E MÉTODOS: Foram analisados artigos originais, publicados entre 2000 e 2011, que envolvessem treino de marcha após a lesão medular, com ou sem suporte parcial de peso corporal, e tecnologias na assistência do treino, como biofeedback e estimulação elétrica funcional, entre outras. RESULTADOS: A maioria dos participantes dos estudos era do sexo masculino; os níveis de lesão variavam de C3 a L3; ASIA teve pontuações de A a D; os tempos de lesão variaram entre 0,3 meses a 33 anos. Também se verificou que não há consenso em relação ao protocolo de TLSP. CONCLUSÃO: O treino locomotor com suporte de peso corporal mostra-se viável na reabilitação de pacientes que sofrem de uma patologia neurológica como a lesão medular. Independentemente do protocolo de treino utilizado, os benefícios referentes ao aumento da força muscular, manutenção ou aumento da densidade óssea, diminuição da frequência cardíaca e aumento do condicionamento físico estão presentes

To evaluate technetium Tc 99m (99mTc) red blood cell scintigraphy as a diagnostic tool for orbital cavernous hemangioma and to differentiate between orbital masses on the basis of their vascularization. We performed 99mTc red blood cell scintigraphy on 23 patients (8 female and 15 male; mean age, 47 years) affected by an orbital mass previously revealed with computed tomography (CT) and magnetic resonance imaging (MRI) and suggesting cavernous hemangioma. In our diagnosis, we considered the orbital increase delayed uptake with the typical scintigraphic pattern known as perfusion blood pool mismatch. The patients underwent biopsy or surgical treatment with transconjunctival cryosurgical extraction when possible. Single-photon emission tomography (SPET) showed intense focal uptake in the orbit corresponding to radiologic findings in 11 patients who underwent surgical treatment and pathologic evaluation (9 cavernous hemangiomas, 1 hemangiopericytoma, and 1 lymphangioma). Clinical or histologic examination of the remaining 22 patients revealed the presence of 5 lymphoid pseudotumors, 2 lymphomas, 2 pleomorphic adenomas of the lacrimal gland, 1 astrocytoma, 1 ophthalmic vein thrombosis, and 1 orbital varix. The confirmation of the preoperative diagnosis by 99mTc red blood cell scintigraphy shows that this technique is a reliable tool for differentiating cavernous hemangiomas from other orbital masses (sensitivity, 100%; specificity, 86%) when ultrasound, CT, and MRI are not diagnostic. Unfortunately, 99mTc red blood cell scintigraphy results were positive in 1 patient with hemangiopericytoma and 1 patient with lymphangioma, which showed increased uptake in the lesion on SPET images because of the vascular nature of these tumors. Therefore, in these cases, the SPET images have to be integrated with data regarding clinical preoperative evaluation and CT scans or MRI studies. On the basis of our study, a complete diagnostic picture, CT scans or MRI studies, and

Management of infantile hemangiomas: Current trends

Full Text Available Infantile hemangiomas (IH are common vascular tumours. IH have a characteristic natural course. They proliferate rapidly during the early infantile period followed by a period of gradual regression over several years. Most of the uncomplicated IH undergo spontaneous involution, with a small proportion of cases requiring intervention. These are children with IH in life-threatening locations, local complications like haemorrhage, ulceration and necrosis and functional or cosmetic disfigurements. Systemic corticosteroids have been the first line of treatment for many years. Recently, non-selective beta-blockers, such as oral propranalol and topical timolol, have emerged as promising and safer therapies. Other treatment options include interferon α and vincristine which are reserved for life-threatening haemangiomas that are unresponsive to conventional therapy. This review mainly focuses on the current trends and evidence-based approach in the management of IH.

1989-01-01

After exsanguination of the lesion and control of arterial inflow and venous outflow, the authors used a transvenous or direct puncture technique for injection of a sclerosing solution (3% sotradecol and ionic contrast material) to treat 18 patients with peripheral arteriovenous malformations or hemangiomas. The results are discussed. Good results were achieved in 12 patients. The other six patients had residual symptoms. Multiple treatment sessions were usually necessary. Short-term management included the use of intravenous heparin, steroids, and antibiotics. No significant long-term complications occurred. Short-term complications, including swelling, local pain, blistering, and localized deep venous thrombosis, occurred in 70% of the patients

We report three cases of extracerebral cavernous hemangiomas in the middle fossa all of which had received radiotherapy. Follow-up study with serial computed tomography during and after irradiation were presented. In Case 1, radiotherapy after partial removal of the tumor reduced the tumor's size and CT number, and facilitated total removal. In Case 2 as well, irradiation was started before the operation. The tumor responded very well to irradiation and showed significant reduction in the size and CT number of the tumor with a dose of about 3,000 rads. Subtotal romoval was possible. In Case 3, the tumor responded very well clinically to irradiation, and vertigo were much improved with a dose of about 3,000 rads, and CT scan at that time showed significant reduction in the size and CT number of the tumor, therefore she only received radiation therapy, no surgical intervention. It is concluded that in cases of extracerebral cavernous hemangioma with massive hemorrhage, radiation of up to 3,000 rads was a method of choice. The treatment results in an increased probability of total removal of the tumor, and moreover the possibility of eliminating surgery. (author)

Full Text Available Primary hepatic marginal zone B-cell malignant lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma is extremely rare. We present a case in which a lesion was diagnosed as 2 contiguous tumors (MALT lymphoma and hemangioma using contrast-enhanced ultrasonography (US with sonazoid. There has been no previous case of contiguous hepatic MALT lymphoma and hemangioma. The present case was a female with no medical history. We detected a snowman-like appearance, which was a tumor of 15 mm in diameter with hypo- and hyper-echogenicities in the lateral and medial parts, respectively, in the Couinaud's segment (S6 of the liver on US. The tumor appeared as a single lesion with a low-density area in the unenhanced phase and prolonged enhancement in the equilibrium phases on dynamic CT. On MRI, the whole lesion showed a low-intensity signal on T1-weighted imaging, but isointensity in the lateral part and high intensity in the medial part were seen on T2-weighted imaging. On contrast-enhanced US, the lateral hypoechoic region was homogenously hyperenhanced in the early vascular phase, and the contrast medium was washed out after about 30 s; in contrast, the medial hyperechoic region was gradually stained from the margin toward the central region. The tumor showed a defect in both hypo- and hyperechoic regions in the postvascular phase. Hemangioma was suspected for the medial part based on the typical image findings, but the lateral part was not given a diagnosis. Thus, surgical resection was performed. The medial part was a hemangioma, and the lateral part was a MALT lymphoma by histopathological findings.

In summary, an 18-year-old young woman presented with an expanding lesion of the nasal bone(s), with a prior history of gradual swelling of the nose. A past history of trauma sustained when she was struck by a tennis ball dated approximately five years before the current presentation. Plain film roentgenograms and a tomographic study showed an expanding lesion of the nasal bone(s) which had the appearance of benignity; the lesion was well demarcated with a narrow zone of transition. The lesional tissue contained small bony opacities in the form of circles and linear and curvilinear strands. The neoplasm was surgically excised and proved to be a benign hemangioma. (orig./SHA)

Full Text Available Thymomas are tumors characterized by a remarkable morphological heterogeneity and variable clinical behavior. This tumor has unique clinical associations, most notably with hematological abnormalities and myasthenia gravis. According with the Müller-Hermelink criteria, there are significant differences between the histological types of thymomas and the association with myasthenia gravis. Among the different histological types, medullary thymoma is the least frequent variant associated with this autoimmune disease. In this report we describe a case of medullary thymoma presenting in a 71-year- old woman with a myasthenic syndrome.Os timomas são tumores caracterizados por grande heterogeneidade morfológica e comportamento clínico variável. Este tumor apresenta associações clínicas singulares, principalmente com doenças hematológicas e com a miastenia gravis.

Diagnosis of sclerosing hemangioma of lung: Don′t rely on fine-needle aspiration cytology diagnosis alone

Directory of Open Access Journals (Sweden)

Kaushik Saha

2013-01-01

Full Text Available Sclerosing hemangioma is a rare variety of benign pulmonary neoplasm. It usually presents as asymptomatic, solitary, peripheral, circumscribed lesions in middle-aged women. Here, we describe a 46-year-old woman presenting to us for evaluation of right parahilar lung mass. Previous chest radiography done 10 years back showed a lung mass of almost similar size. Computed Tomography (CT-guided fine-needle aspiration cytology (FNAC was suggestive of adenocarcinoma of lung. A well-circumscribed, capsulated, ovoid mass measuring 5.6 cm × 4 cm × 3 cm, adjacent to the transverse fissure of the right lung was excised by lateral thoracotomy. Histopathological examination along with immunohistochemistry was suggestive of sclerosing hemangioma of lung. A pathologist must consider the clinicoradiological features before coming to a final diagnosis of lung malignancy from FNAC. Whenever there is any confusion regarding lung mass, thoracotomy must be done for arriving at an exact diagnosis from histopathology.

Verrucous hemangioma (VH) is a rare, congenital and localized vascular malformation, which usually presents as warty, bluish, vascular papules, plaques, or nodules, mainly on the lower extremities. Linear presentation of the disease is rare. A deep biopsy is necessary to confirm the clinical diagnosis by histopathological examination, with dermoscopy acting as a useful tool for evaluating the precise vascular structure. Here, we report on a 13-year-old female child with linear VH presenting over her foot since infancy and dermoscopic findings of VH along with the clinical-pathologic features.

Descreve-se o caso de um recém-nascido de termo, fruto de uma gestação vigiada com ecografias obstétricas sem alterações, que apresentava ao nascimento, na face anterior da coxa esquerda, uma massa de 5x4,5cm, mole, depressível, acinzentada, com algumas telangiectasias periféricas e halo periférico esbranquiçado, sem frémito palpável ou ulceração. Hemodinamicamente estável, sem trombocitopenia. A ecografia e a ressonância magnética apoiaram a suspeita clinica de RICH, que foi corroborada imunohistologicamente. Após 15 meses verificou- -se regressão espontânea e completa do tumor. O conhecimento da clínica, evolução e prognóstico deste raro hemangioma é fundamental para o diagnóstico e seguimento adequados, evitando intervenções desnecessárias, assim como para tranquilização dos cuidadores.

Optimal MR pulse sequences for hepatic hemangiomas : comparison of T2-weighted turbo-spin-echo, T2-weighted breath-hold turbo-spin-echo, and T1-weighted FLASH dynamic imaging

To optimize MR imaging pulse sequences in the imaging of hepatic hemangioma and to evaluate on dynamic MR imaging the enhancing characteristics of the lesions. Twenty patients with 35 hemangiomas were studied by using Turbo-spin-echo (TSE) sequence (T2-weighted, T2- and heavily T2-weighted breath-hold) and T1-weighted FLASH imaging acquired before, immediately on, and 1, 3 and 5 minutes after injection of a bolus of Gd-DTPA (0.1mmol/kg). Phased-array multicoil was employed. Images were quantitatively analyzed for lesion-to-liver signal difference to noise ratios (SD/Ns), and lesion-to-liver signal ratios (H/Ls), and qualitatively analyzed for lesion conspicuity. The enhancing characteristics of the hemangiomas were described by measuring the change of signal intensity as a curve in T1-weighted FLASH dynamic imaging. For T2-weighted images, breath-hold T2-weighted TSE had a slightly higher SD/N than other pulse sequences, but there was no statistical difference in three fast pulse sequences (p=0.211). For lesion conspicuity, heavily T2-weighted breath-hold TSE images was superior to T2-weighted breath-hold or non-breath-hold TSE (H/L, 5.75, 3.81, 2.87, respectively, p<0.05). T2-weighted breath-hold TSE imaging was more effective than T2-weighted TSE imaging in removing lesion blurring or lack of sharpness, and there was a 12-fold decrease in acquisition time (20sec versus 245 sec). T1-weighted FLASH dynamic images of normal liver showed peak enhancement at less than 1 minute, and of hemangioma at more than 3 minutes;the degree of enhancement for hemangioma decreased after a 3 minute delay. T2-weighed breath-hold TSE imaging and Gd-DTPA enhanced FLASH dynamic imaging with 5 minutes delay are sufficient for imaging hepatic hemangiomas

15, 16-Dihydrotanshinone I Inhibits Hemangiomas through Inducing Pro-apoptotic and Anti-angiogenic Mechanisms in Vitro and in Vivo

Full Text Available Infantile hemangioma (IH is a common and benign vascular neoplasms, which has a high incidence in children. Although IH is benign, some patients experience complications such as pain, functional impairment, and permanent disfigurement. Treatment options for IH include corticosteroids, surgery, vincristine, interferon or cyclophosphamide. However, none of these modalities are ideal due to restrictions or potential serious side effects. There is thus a great need to explore novel treatments for IH with less side effects. Angiogenesis, vasculogenesis and tumorigenesis are the main features of IH. Tanshen is mostly used in Chinese traditional medicine to treat hematological abnormalities. Therefore, the aim of our study was to evaluate anti-proliferation and anti-angiogenesis effects on hemangiomas cells by extracted Tanshen compounds compared with propranolol, the first-line treatment for IH currently, both in vitro and in vivo. Cell viability, apoptosis, protein expression and anti-angiogenesis were analyzed by CCK8, Annexin V staining, Western blot and tube formation, respectively. The anti-tumor activity in vivo was evaluated using a mouse xenograft model. Fourteen major compounds extracting from Tanshen were screened for their ability to inhibit hemangiomas cells. Of the 14 compounds investigated, 15,16-Dihydrotanshinone I (DHTS was the most potent modulator of EOMA cell biology. DHTS could significantly decrease EOMA cells proliferation by inducing cell apoptosis, which is much more efficient than propranolol in vitro. DHTS increased the expression of several apoptosis-related proteins, including caspase9, caspase3, PARP, AIF, BAX, cytochrome c, caspase8 and FADD and significantly inhibited angiogenesis, as indicated by reduced tube formation and diminished expression of vascular endothelial cell growth factor receptor 2 and matrix metalloproteinase 9. In nude mice xenograft experiment, DHTS (10 mg/kg could significantly inhibit the tumor

This study aimed to illustrate the validity of the treatment with vertebroplasty (VP) in patients with aggressive or symptomatic vertebral hemangioma (VH) with or without epidural extension. From January 2003 to December 2007, 24 consecutive patients have been treated with VP, for a total of 36 vertebral bodies affected by VH: two cervical, ten dorsal, 24 lumbar. All the patients complained of a pain syndrome resistant to continuous medical medication; four of 24 patients also presented aggressive magnetic resonance features of the vertebral lesion and two patients showed also epidural extension. A unipedicular approach has been performed in 16 patients; a bipedicular approach has been performed in six, while for the cervical spine an anterior-lateral approach with manual dislocation of the carotid axis has always been performed. Bone biopsy was never done. All procedures have been carried out with local anesthesia, except for the treatment of the cervical hemangiomas which has always been performed under general anesthesia. Four vertebral bodies in the same session have been treated in one case. Results have been evaluated with the visual analog scale and the Oswestry Disability Index methods. In all the patients, in the following 24-72 h, a successful outcome has been observed with a complete resolution of pain symptom. Extravertebral vascular or discal cement leakage has been observed in four patients, without any onset of clinical radicular syndrome due to epidural diffusion. Clinical and radiological follow-up until 4 years has been performed in 12 patients and it showed stability of the treatment and absence of pain. Percutaneous treatment with VP for aggressive and symptomatic vertebral hemangiomas even with epidural extension is a valuable, mini-invasive, and quick method that allows a complete and enduring resolution of the painful vertebral symptoms without findings of fracture of a vertebral body adjacent or distant to the one treated.

Full Text Available A biópsia de medula óssea é parte integrante do estadiamento e seguimento de pacientes com doenças hematológicas. Nódulos linfóides são um achado comum, usualmente observados em associação com doenças inflamatórias crônicas, infecção, hemólise, síndromes mieloproliferativas e doenças auto-imunes. São, em geral, considerados reacionais. Sendo a medula óssea o sítio extranodal mais comumente envolvido nos linfomas foliculares, o diagnóstico diferencial mais importante é a infiltração medular por doença linfoproliferativa. Do ponto de vista prático, os infiltrados linfóides são, em geral, facilmente distinguíveis ao estudo histológico. Agregados reacionais são pequenos, têm bordas delimitadas, são compostos por uma população celular heterogênea e têm localização central. Nódulos malignos infiltram a medula óssea na região paratrabecular e são compostos por células clivadas. A análise imunofenotípica, utilizando um painel de anticorpos monoclonais, é capaz de definir a linhagem celular, subpopulação e estágio de diferenciação da população neoplásica, contribuindo para a confirmação do diagnóstico. Nos casos controversos, a análise molecular da proliferação linfóide pode ser útil. A monoclonalidade pode ser demonstrada pela restrição de cadeias leves ou através do rearranjo do DNA da cadeia pesada das imunoglobulinas. Idealmente, os resultados da análise molecular devem ser interpretados em conjunto com a análise morfológica e imunofenotípica. A morfologia continua sendo o padrão-ouro na avaliação da infiltração medular por linfoma folicular e as análises imunofenotípica e molecular devem ser consideradas complementares.Bone marrow trephine biopsies are an integral part of the diagnosis, staging and follow-up of patients with haematologic disorders.

Full Text Available Elias Chelala, Ali Dirani, Ali Fadlallah Saint-Joseph University, Faculty of Medicine, Beirut, Lebanon Abstract: We report a case of a patient known to have a von Hippel–Lindau disease with documented progressive juxtapapillary retinal capillary hemangioma (JRCH with well-preserved visual acuity (VA and visual field (VF. The patient received a single injection of intravitreal ranibizumab (IVR. Six months after IVR injection, the JRCH showed reduced vascularization, fibrosis, and mild shrinkage, and VA and VF remained unchanged. IVR therapy might therefore be considered as an alternative treatment for progressive JRCH, especially in patients with well-preserved VA and VF.

Full Text Available The histological predominance of one component in a germ cell tumor can lead to a mistaken diagnosis. Here, we describe a mediastinal teratoma with predominant vascular proliferation (>90% which on fine needle biopsy was diagnosed as a pulmonary hemangioma. Later, resection specimen revealed other components constituting ~4%, changing the diagnosis while illustrating theimportance of careful evaluation. A 37-year-old Caucasian male with shortness of breath, weight loss, and history of recently resolved pneumonia was diagnosed with hemangioma, after a computed tomography guided fine needle biopsy of a -16.3-cm mediastinal pulmonary mass revealed abundant benign vascular elements. Following tumor excision, ~94% of the sample exhibited predominant vascular elementsThe mass also exhibited rare focal areas of malignant epithelium in a reticular arrangement and undifferentiated pleomorphic cells associated with vascular invasion. These atypical epithelial cells were positive for CD30, pan CK, AFP, β-HCG and CD 117, thusprocuring a diagnosis of mediastinal mixed germ cell tumor. Although mixed germ cell tumors consist of various tissue types, diagnosis can be easily overlooked if one component dominates. Therefore, obtaining adequate representative neoplasm samples, and sectioning the samples thoroughly, searching for coexisting tissue types is critical for accurate diagnosis.

Full Text Available AIM:To compare the efficacy and safety of photodynamic therapy (PDT with overlapping multiple spots and single spot for treating circumscribed choroidal hemangioma.METHODS:Twenty-two patients (22 eyes with symptomatic circumscribed choroidal hemangioma received PDT treatment. Fourteen patients received overlapping spots (two to three spots PDT, whereas eight patients received single-spot PDT. Laser was used at 50J/cm2 for 83s in the overlapping-spot group and 50J/cm2 for 166s in the single-spot group. Clinical examination, funduscopy, fluorescein angiography, and ultrasonography were performed at baseline and after treatment.RESULTS:The mean follow-up time was 28.5±8.0 months in the overlapping-spot group and 27.0±5.0 months in the single-spot group. Nine patients (64.2% had their vision improved over two lines on the Snellen chart, and five patients showed stable visual acuity in the overlapping-spot group. The mean thickness of tumor decreased from 2.7±0.8mm to 1.2±0.9mm, and the mean greatest tumor linear dimension decreased from 7.4±1.5mm to 4.5±3.5mm after treatment. In the single-spot group, two patients (25% had their vision improved over two lines on the Snellen chart, and six patients had unchanged stable vision. The mean tumor thickness in this group decreased from 2.5±0.7mm to 1.4±1.0mm, and the mean greatest tumor linear dimension decreased from 7.2±1.3mm to 4.7±3.6mm. No significant differences in visual improvement and tumor regression were found between the two groups.CONCLUSION: Overlapping-spot PDT under appropriate treatment parameters and strategies is as effective and safe as single-spot PDT for treating symptomatic circumscribed choroidal hemangioma. Improved or stabilized visual acuity was achieved as a result of tumor regression.

Intractable hiccup as the presenting symptom of cavernous hemangioma in the medulla oblongata: a case report and literature review.

Science.gov (United States)

Lee, Kyung-Hwa; Moon, Kyung-Sub; Jung, Min-Young; Jung, Shin

2014-06-01

A case of intractable hiccup developed by cavernous hemangioma in the medulla oblongata is reported. There have been only five previously reported cases of medullary cavernoma that triggered intractable hiccup. The patient was a 28-year-old man who was presented with intractable hiccup for 15 days. It developed suddenly, then aggravated progressively and did not respond to any types of medication. On magnetic resonance images, a well-demarcated and non-enhancing mass with hemorrhagic changes was noted in the left medulla oblongata. Intraoperative findings showed that the lesion was fully embedded within the brain stem and pathology confirmed the diagnosis of cavernous hemangioma. The hiccup resolved completely after the operation. Based on the presumption that the medullary cavernoma may trigger intractable hiccup by displacing or compression the hiccup arc of the dorsolateral medulla, surgical excision can eliminate the symptoms, even in the case totally buried in brainstem.

This is a report of case with the extracerebral cavernous hemangioma in the middle fossa in which total removal was carried out after radiotherapy. Follow-up study with computed tomography during and after irradiation are presented. A 44-year-old house-wife complained of a decreased vision of the both eyes and paresis of the left upper and lower limbs. CT scan revealed a slightly high density area in the right middle cranial fossa which was markedly enhanced with contrast media. Right carotid angio-graphy demonstrated a large avascular mass in the right middle fossa and no feeding artery or draining vein was visualized except a faint irregular stain in the venous phase. An attempt to total removal of the tumor had failed to succeed because of extensive hemorrhage from the tumor. Histological examination revealed a cavernous hemangioma. Irradiation with a total dose of 5000 rads was delivered. After irradiation CT scan revealed a marked decrease of size and EMI number of the tumor. At this stage, hypervascular mass lesion with feeding arteries was noted in conventional angiography. Tumor stain in prolonged injection angiography was also visualized. In the second operation, removal of the tumor was performed without any difficulty and hemorrhage was controlled easily by electrocoagulation. Histology revealed a marked narrowing of vessels with an increase in the connective tissues. In the central part of specimen, there noted findings of coagulation necrosis, intraluminal thrombus formations and so on, which were attributed to the influence of radiation. It is concluded that in case of an extracerebral cavernous hemangioma with massive hemorrhage, radiation of up to 3000 - 5000 rads was a method of choice. The treatment results in an increase of probability of total removal of the tumor.

E-selectin mediates stem cell adhesion and formation of blood vessels in a murine model of infantile hemangioma.

Science.gov (United States)

Smadja, David M; Mulliken, John B; Bischoff, Joyce

2012-12-01

Hemangioma stem cells (HemSCs) are multipotent cells isolated from infantile hemangioma (IH), which form hemangioma-like lesions when injected subcutaneously into immune-deficient mice. In this murine model, HemSCs are the primary target of corticosteroid, a mainstay therapy for problematic IH. The relationship between HemSCs and endothelial cells that reside in IH is not clearly understood. Adhesive interactions might be critical for the preferential accumulation of HemSCs and/or endothelial cells in the tumor. Therefore, we studied the interactions between HemSCs and endothelial cells (HemECs) isolated from IH surgical specimens. We found that HemECs isolated from proliferating phase IH, but not involuting phase, constitutively express E-selectin, a cell adhesion molecule not present in quiescent endothelial cells. E-selectin was further increased when HemECs were exposed to vascular endothelial growth factor-A or tumor necrosis factor-α. In vitro, HemSC migration and adhesion was enhanced by recombinant E-selectin but not P-selectin; both processes were neutralized by E-selectin-blocking antibodies. E-selectin-positive HemECs also stimulated migration and adhesion of HemSCs. In vivo, neutralizing antibodies to E-selectin strongly inhibited formation of blood vessels when HemSCs and HemECs were co-implanted in Matrigel. These data suggest that endothelial E-selectin could be a major ligand for HemSCs and thereby promote cellular interactions and vasculogenesis in IH. We propose that constitutively expressed E-selectin on endothelial cells in the proliferating phase is one mediator of the stem cell tropism in IH.

2006-01-01

Full Text Available Este trabajo consiste en un estudio de transferencia simultánea de calor y masa con la finalidad de determinar la matriz de coeficientes de difusión multicomponente en fase líquida. La literatura reporta una fórmula semi-empírica desarrollada por Bandrowski y Kubaczka para calcular la matriz de coeficientes de difusión multicomponente, método que separa las contribuciones cinética y termodinámica a la transferencia de masa e incluye un exponente empírico para realizar cálculos más precisos. El presente trabajo propone la estimación del exponente empírico en un amplio rango de temperaturas estudiando la redistribución de composición en un capilar no isotérmico y no saturado, tomando en consideración las no idealidades descritas por la matriz de coeficientes de factores termodinámicos. Para tal fin, se ha utilizado el sistema ternario agua-etanol-acetona a dos diferentes rangos de temperaturas y dos diferentes grados de saturación. Los resultados muestran que el método es efectivo ya que se obtuvieron valores consistentes del exponente empírico que modifica la matriz de factores termodinámicos. Además, se evidencia que el exponente es dependiente de la temperatura.

2018-01-01

Conclusion: Seller cavernous hemangioma (SCH is an extremely rare lesion that can be misdiagnosed. It is characterized by clinico-radiological features similar to those of other lesions such as pituitary macroadenoma and should be included in the differential diagnosis. The endoscopic endonasal transsphenoidal (EET approach with subtotal/total resection appears to be a feasible option for debulking, with less surgical complications. Nonetheless, combining stereotactic radiosurgery will reduce postsurgical morbidities.

This case report and literature review reports on a rare case of facial nerve hemangioma (FNH) involving the vertical facial nerve (FN) segment, and discusses the clinical presentation, imaging, pathogenesis, and management of these rare lesions. A 53-year-old male presented with a 10-year history of right hemifacial twitching and progressive facial paresis (House-Brackmann grading score V/VI). The computed tomography and magnetic resonance imaging studies confirmed an expansile lesion along the vertical FN segment. Excision and histopathologic examination demonstrated FNH. FNHs involving the vertical FN segment are extremely rare. Despite being rare lesions, we believe that familiarity with the presentation and management of FNHs are imperative. Laryngoscope, 2012.

Infantile hemangiomas (IH) at risk for complications need to be recognized early. We sought to determine if parents are able to assess, after e-learning, whether their child has an IH, is at risk for complications, and needs to be seen (urgently) by a specialist. This was a prospective study of 158 parents participating in an IH e-learning module. Parents were asked to assess their child's skin abnormality. A dermatologist answered the same questions (by e-consult). The 2 assessments were compared. Parents showed a 96% concordance with the dermatologist for correct diagnosis after e-learning. Concordances were 79%, 75%, and 84% (P e-learning module. E-learning by parents could result in earlier presentation and treatment of high-risk IH.

Between 1920 and 1959, 9675 women were irradiated in infancy for skin hemangioma at Radiumhemmet, Stockholm. They were exposed to low to moderate doses of ionizing radiation. The mean age at first exposure was 6 months and the mean absorbed dose to the breast anlage was 0.39 Gy (range 50 years after exposure the ERR at 1 Gy was 2.25 (95% CI 0.59-5.62). The fitted excess absolute risk (EAR) was 22.9 per 10 4 breast-year gray. The breast absorbed dose and time after exposure were important risk determinants for breast cancer excess risk. Forty to 50 years of follow-up was necessary for the excess risk to be expressed. The study confirms previous findings that the breast anlage of female infants is sensitive to ionizing radiation. 17 refs., 6 figs

A 15-year-old gelding presented with a progressive lameness of the left forelimb of 2.5 months duration. Clinically, a dilation of the deep flexor tendon sheath with a firm elastic consistency and a pronounced tenderness was noted. Ultrasonically, a marked swelling of the flexor tendon sheath with an irregular density of the mesotendineum was observed. The white, firm material forming a nodular distension of the flexor tendon sheath with a diameter of approximately 1 cm was excised and sent for histopathological examination. Biopsies of the deep flexor tendon and corresponding tendon sheath were sent for histopathological evaluation. Histologically, the mass consisted of clefts and numerous anastomosing vascular channels extending between the collagen fibers of the deep flexor tendon. These capillary-like spaces were lined by neoplastic cells that were flattened to polygonal and contained few erythrocytes. There was 0 to 1 mitotic figure per 10 high power fields (400×). Immunohistochemically, the neoplastic cells stained positive for vimentin and factor VIII-related antigen. Adjacent to the neoplastic endothelial cells located pericytes expressed α-smooth muscle actin antigen. Based on the histopathological and immunohistochemical features, synovial hemangioma was diagnosed. One year after surgery, the horse has shown no lameness.

Background and Purpose: Radiotherapy is an integral part of various therapeutic regimens in pediatric and adult oncology. Endocrine dysfunction, neurologic and psychiatric deficits, secondary malignancies and radiation-induced necrosis are well-known possible late effects of cranial irradiation. However, only sporadic cases of radiation-induced cavernous hemangiomas (RICH) have been reported so far. Patients and Methods: Pediatric patients who underwent cranial radiation therapy for malignant diseases between January 1980 and December 2003 were retrospectively analyzed. After the end of therapy they entered a detailed follow-up program. Results: Of 171 patients, eight (three patients with medulloblastoma, three patients with acute lymphoblastic leukemia, and one patient each with ependymoma and craniopharyngioma) developed intracerebral cavernoma 2.9-18.4 years after irradiation representing a cumulative incidence (according to the Kaplan-Meier method) of 2.24%, 3.86%, 4.95%, and 6.74% within 5, 10, 15, and 20 years following radiation therapy, respectively. In patients treated in the first 10 years of life, RICH occurred with shorter latency and significantly more often (p = 0.044) resulting in an even higher cumulative incidence. Conclusion: These findings and previously published cases show that cavernous hemangiomas may occur after irradiation of the brain several years after the end of therapy irrespective of the radiation dose and type of malignancy. Particularly children < 10 years of age at the time of irradiation are at higher risk. Since patients with RICH frequently do not show symptoms but hemorrhage is a possible severe complication, imaging of the central nervous system should be performed routinely for longer follow- ups, particularly in patients who were treated as young children.

Full Text Available Se informa un caso de hemangioma cavernoso del mesosigmoide, su presentación clínica, diagnóstico y tratamiento, y se ofrece una revisión de la literatura asequible sobre el tema, para lo cual se realizó una búsqueda en las bases de datos de Medigraphic, Cochrane, Medline y PubMed. El paciente es un hombre de 72 años de edad, que se presentó con dolor abdominal, estreñimiento, pérdida de peso y masa tumoral en la fosa ilíaca izquierda. A pesar de las investigaciones imaginológicas y endoscópica, no se pudo hacer el diagnóstico preoperatorio. Se trató por laparotomía y resección del tumor, y el diagnóstico se confirmó por estudio histopatológico. El hemangioma cavernoso del mesosigmoide es un tumor raro, difícil de diagnosticar preoperatoriamente, a pesar de las avanzadas técnicas imaginológicas. La escisión quirúrgica y el examen histológico pueden ser los únicos medios para el diagnóstico.

Objective: To further reduce the adverse reactions of vascular embolization therapy for cavernous hemangioma of the liver (CHL) in order to find better embolizing agents. Methods: Sixty CHL patients were randomly and evenly divided into three groups: embolization therapy with sodium alginate microsphere(SAM) + pingyangmycin lipiodol emulsion (PLE) (group SAM + PLE), PLE (group PLE) and SAM (group SAM). The routine postoperative symptomatic treatments were conducted, including odynolysis, liver-protection and antiinflammatory therapy. The liver function and the intraoperative or postoperative discomfort symptoms before and 7 days after operation, and the changes in tumors were examined with CT scan. Clinical symptoms 3 months after operation were respectively compared. Results: The greatest impact on liver function was seen in group PLE among the three groups. The maximum intraoperative or postoperative discomfort symptoms were seen in group SAM, but the therapeutic effectiveness of the three groups had no significant difference. Conclusion: SAM + PLE is a safe and effective embolizing agent, being user-friendly, minor in the effect on liver function and light in the intraoperative and postoperative reaction. It is recommended that SAM + PLE be widely used for cavernous hemangioma of the liver. (authors)

Intramedullary cavernous hemangiomas are vascular malformations that can be located throughout the entire central nervous system. They are more frequently found in brain than in spinal cord, where it is only possible to diagnose them by magnetic resonance (RM): We present four cases of intramedullary spinal cord cavernoma, three of which were located in the thoracic spine and one in cervical spine. Computed tomography was ineffective in their diagnosis. However, MR disclosed there presence of well-defined tumors producing a thickening of the spinal cord. The signal was heterogeneous in both T1 and T2-weighted images. There were low signal areas due to the presence of calcium and hemosiderin and high intensity signals provoked by methemoglobin within the lesions, which were scarcely enhanced by intravenous gadolinium administration. One of the lesions presented in the form of a large intramedullary hematoma. (Author) 8 refs

Purpose: Patients with choroidal hemangioma (CH), a benign ocular hamartoma, frequently presents with visual disturbance as a result of exudative retinal detachment (RD), which originates in subretinal fluid accumulation. We report our experience using the Leksell Gamma Knife in the management of symptomatic CH. Methods and Materials: Seven patients with symptomatic CH (circumscribed form in 3 patients and diffuse form in 4) were treated with the Leksell Gamma Knife at our institution during a 7-year period. All patients presented with exudative RD involving the macula that resulted in severe visual deterioration. The prescription dose to the target margin was 10 Gy in all cases. The mean tumor volume receiving the prescription dose was 536 mm 3 (range, 151–1,057). The clinical data were analyzed in a retrospective fashion after a mean follow-up of 34.4 months (range, 9–76). Results: The resolution of exudative RD was achieved within 6 months, and the visual acuity of the affected eye had improved at the latest follow-up examination (p = .018) in all patients. No recurrence of exudative RD occurred. Thinning of the CHs was observed in most patients; however, symptomatic radiation toxicity had not developed in any of the patients. Conclusion: Symptomatic CHs can be safely and effectively managed with Gamma Knife radiosurgery using a marginal dose of 10 Gy.

The authors report on their experience with liver hemangioma (LH) diagnosis by means of a semplified method- that is, the simultaneous, in vivo, double labelling of liver reticuloendothelial system (RES) and of red blood cells (RBC) by 99m Tc. Twenty-eight patients with US diagnosis of suspected LH and 15 controls were examined after sequential iv injection of SnCl 2 , of 99m Tcμcolloid albumin and, after liver scintigraphy, of 99m Tc-pertechnetate to conclude in vivo RBC labelling. All patients underwent CT and, if necessary, CT-guided biopsy. Focal colloid defects were shown in 6/28 cases (expansive process). 15/15 controls showed unchanged non-filling defects after double labelling. Finally, the authors point out that, in the diagnosis of LH, sequential double labelling of liver RES and RBC appears to be a quicker scintigraphic techique than conventional ones. Moreover, this technique has the same high specificity and sensitivity as more time-consuming ones

The “Endothelialized Muscularis Mucosae”: A Case Report Describing a Large Cavernous Hemangioma at the Terminal Ileum and a New Histologic Clue for Preoperative Diagnosis from Endoscopic Biopsy

2015-01-01

Cavernous hemangiomas of the gastrointestinal tract are quite rare and, until now, have been difficult to diagnose preoperatively due their nonspecific presentations and imaging features, as well as a lack of histologic description pertaining to small superficial biopsies such as those obtained endoscopically. We report a unique case of a 4 cm transmural cavernous hemangioma in the terminal ileum with literature review and describe a new histologic finding—the “endothelialized muscularis mucosae,” which was discovered upon review of the endoscopic biopsy and could potentially facilitate preoperative diagnosis of these lesions from endoscopic biopsies in the future. These lesions have classically required surgical resection in order to make a definitive diagnosis and rule out malignancy, with which they share many historical and radiographic features. Due to their potential to cause bowel obstruction, intussusception, perforation, and hemorrhage, these lesions may ultimately require surgical resection to relieve symptoms or prevent or treat complications—however, surgical planning and patient counseling could be greatly improved by a preoperative diagnosis. Therefore, gastroenterologists, pathologists, and surgeons should be aware of the “endothelialized muscularis mucosae” which can be very helpful in diagnosing GI cavernous hemangiomas from endoscopic biopsies.

Pregnancy related compressive myelopathy secondary to vertebral hemangioma is a rare occurrence and its treatment antepartum is rare. We report a 22-year-old lady in her 26th-week of pregnancy who was treated in two stages--antepartum with a laminectomy and posterior stabilization. This resulted in complete recovery of the neurological deficits. She delivered a normal baby after 3 months, following which a corpectomy and fusion was performed. This two-staged approach appears safe and effective in treating symptomatic vertebral haemangiomas causing neurological deficits during pregnancy. A review of relevant literature has been done.

Objective: To test interobserver variability of ADC measurements and compare the diagnostic performances of free-breathing diffusion-weighted (FBDW) with that of T2-weighted FSE (T2WFSE) MR imaging for differentiating between cavernous hemangiomas and untreated malignant hepatic neoplasms. Materials and methods: Thirty-five patients with cavernous hemangiomas and 35 with untreated hepatic malignant neoplasms had FBDW and T2WFSE MR imaging. Hepatic lesions were characterized with ADC measurement and visual evaluation. Interobserver agreement for ADC measurement was calculated. Association between ADC value and lesion type was assessed using univariate analysis. Sensitivity, specificity and accuracy of ADC values and visual evaluation of MR images for the diagnosis of untreated malignant hepatic neoplasm were compared. Results: ADC measurements showed excellent interobserver correlation (intraclass correlation coefficient = 0.980). Malignant neoplasms had lower ADC values than hemangiomas for the two observers (1.11 x 10 -3 mm 2 /s ± .21 x 10 -3 vs. 1.77 x 10 -3 mm 2 /s ± .29 x 10 -3 for observer 1 and 1.11 x 10 -3 mm 2 /s ± .19 x 10 -3 vs. 1.79 x 10 -3 mm 2 /s ± .32 x 10 -3 for observer 2) and univariate analysis found significant correlations between lesion type and ADC values. Depending on ADC threshold value, accuracy for the diagnosis of malignant neoplasm varied from 82.9% to 94.3%. Using visual evaluation, FBDW showed better specificity and accuracy than T2WFSE MR images for the diagnosis of malignant neoplasm (97.1% vs. 77.1% and 94.3% vs. 62.9%, respectively). Conclusion: FBDW imaging provides reproducible quantitative information and surpasses the value of T2WFSE MR imaging for differentiating between cavernous hemangiomas and untreated malignant hepatic neoplasms.

Since 2014, cases of hemangioma associated with avian leukosis virus subgroup J (ALV-J) have been emerging in commercial chickens in Guangxi. In this study, four strains of the subgroup J avian leukosis virus (ALV-J), named GX14HG01, GX14HG04, GX14LT07, and GX14ZS14, were isolated from chickens with clinical hemangioma in 2014 by DF-1 cell culture and then identified with ELISA detection of ALV group specific antigen p27, the detection of subtype specific PCR and indirect immunofluorescence assay (IFA) with ALV-J specific monoclonal antibody. The complete genomes of the isolates were sequenced and it was found that the gag and pol were relatively conservative, while env was variable especially the gp85 gene. Homology analysis of the env gene sequences showed that the env gene of all the four isolates had higher similarities with the hemangioma (HE)-type reference strains than that of the myeloid leukosis (ML)-type strains, and moreover, the HE-type strains' specific deletion of 205-bp sequence covering the rTM and DR1 in 3'UTR fragment was also found in the four isolates. Further analysis on the sequences of subunits of env gene revealed an interesting finding: the gp85 of isolates GX14ZS14 and GX14HG04 had a higher similarity with HPRS-103 and much lower similarity with the HE-type reference strains resulting in GX14ZS14, GX14HG04, and HPRS-103 being clustered in the same branch, while gp37 had higher similarities with the HE-type reference strains when compared to that of HPRS-103, resulted in GX14ZS14, GX14HG04, and HE-type reference strains being clustered in the same branch. The results suggested that isolates GX14ZS14 and GX14HG04 may be the recombinant strains of the foreign strain HPRS-103 with the local epidemic HE-type strains of ALV-J.

Full Text Available A doença de Creutzfeldt-Jakob (DCJ é a encefalopatia espongiforme subaguda transmissível mais frequente nos seres humanos. Aproximadamente 85% dos casos pertencem à forma esporádica da doença. Os outros 15% consistem na forma genética e iatrogênica. Relatamos o caso de uma paciente com a forma esporádica da doença de Creutzfeldt-Jakob, com comprometimento medular e apresentação clínica caracterizada por síndrome demencial e cerebelar, miofasciculação com arreflexia difusa e crises convulsivas do tipo tônico-clônico generalizada. É rara a associação das duas últimas manifestações clínicas. O caso foi considerado como provável DCJ até confirmação por autópsia e imunohistoquímica. Concluímos que se deve sempre pensar na DCJ em pacientes que apresentam demência rapidamente progressiva e, na ausência de sinais piramidais ou extrapiramidais, pensar em acometimento periférico e/ou medular.Creutzfeldt-Jakob disease (CJD is the most common subacute transmissible spongiform encephalopathy. Approximately 85% of the cases are sporadic. The remaining 15% consist of genetic and iatrogenic forms. We report a sporadic form of CJD with spinal cord involvement and a clinical manifestation characterized by dementia and cerebellar syndrome, myofasciculation with absent reflexes and seizures. The two last manifestations are rare. The clinical hypothesis was probable CJD which was confirmed with autopsy and immunohistochemistry. We conclude that CJD should always be suspected when rapidly progressive dementia occurs and the absence of pyramidal or extrapyramidal signs suggest a spinal cord and/or peripheral nerve involvement.

The infectious etiology (viral and bacterial was predominant in 37.6 %, with 11.9 infected with HTLVI. Although the INR is a reference center, the findings can’t be generalized because it isn’t a representative sample of the Peruvian population, further studies are necessary to propose strategies for prevention and control, considering the high cost of integral rehabilitation treatment in these patients.

Infantile hemangiomas (IH) are common vascular growths that occur in 5-10% of neonates and have the potential to cause disfiguring and even life-threatening complications. Currently, no objective tool exist to monitor either progression or treatment of IH. To address this unmet clinical need, we have developed a handheld wireless device (HWD) that uses diffuse optical spectroscopy for the assessment of IH. The system employs 4 wavelengths (l=780nm, 805nm, 850nm, and 905nm) and 6 source-detector pairs with distances between 0.6 and 20 mm. Placed on the skin surface, backreflection data is obtained and a multispectral evolution algorithm is used to determine total hemoglobin concentration and tissue oxygen saturation. First results of an ongoing pilot study involving 13 patients (average enrollment age = 25 months) suggest that an increase in hypoxic stress over time can lead to the proliferation of IH. Involuting IH lesions showed an increase in tissue oxygen saturation as well as a decrease in total hemoglobin.

2012-01-01

Purpose: An evaluation of dose–response relationship and an attempt to define predictive factors. Methods and Materials: A total of 137 cases of painful vertebral hemangioma irradiations (101 patients). Fraction dose (fd) varied from 2 to 15 Gy (123 fractionated and 14 radiosurgical treatments), and total dose (TD) from 8 to 30 Gy (111 cases irradiated with fd of 2 GY to TD of 24 Gy). We evaluated pain relief, changes in analgesic requirements, and reossification. Results: Means of pain relief 1, 6, 12, and 18 months after radiotherapy (defined as a decrease of primary pain level expressed in percent) were 60.5%, 65.4%, 68.3%, and 78.4%, respectively. Proportion of patients with no need for analgesics and patients using tramadol were 39%, 40%, 44%, 57%, and 20%, 17%, 22%, and 11% in these times. The proportion of patients experiencing complete/partial pain relief changed from 36/48% 1 month, to 64/22% 1.5 years after radiotherapy. No impact of radiotherapy on reossification was found. The positive impact of fd and TD increase for analgesics uptake reduction and pain relief was found. An increase of the fd by 1 Gy results in 27% chance of analgesics uptake reduction and 3.8% reduction of pain, whereas 14% analgesics uptake reduction and 2.2% of pain reduction in case of the TD. The predictive factors improving results were found: female gender, older age, better performance states (the chance of the lower analgesic treatment decreases over 2.5 times in comparison to the higher Zubrod degree), bigger Hb concentration, shorter symptoms duration and lower analgesics uptake before radiotherapy. Conclusions: The obtained data support the efficacy of radiotherapy in improving pain secondary to vertebral hemangioma, with the degree of pain amelioration being related to increasing fd and TD. The positive predictive factors were defined: female gender, older age, better performance status, increased Hb concentration, shorter symptoms duration, and lower analgesics uptake

The nonselective beta-blocker propranolol is the current criterion standard for treatment of infantile hemangiomas (IHs) and the first therapy that the U.S. Food and Drug Administration has approved for the condition, but concern about adverse effects, such as bronchospasm, hypoglycemia, and sleep disturbances, has sparked interest in the use of alternative agents such as the selective β1 antagonist atenolol. Our aim was to compare the efficacy and adverse effect profiles of atenolol with those of propranolol in the treatment of IHs in a retrospective noninferiority trial. Twenty-seven children with IHs treated with atenolol according to the Cleveland Clinic foundation's standardized clinical assessment and management plan (SCAMP) met inclusion criteria and were compared with a matched group of 53 children with IHs treated with propranolol. Three reviewers assessed response to therapy using a modified version of the previously validated Hemangioma Activity Score (HAS). The mean change in HAS was -2.94 ± 1.20 for patients treated with atenolol and -2.96 ± 1.42 for those treated with propranolol. There was no statistically significant difference in pre- and posttreatment modified HAS scores between the two groups (p = 0.60). There was no significant difference in the overall rate of adverse effects (p = 0.10), although 11% of patients treated with propranolol experienced reactive airway symptoms, whereas this was not seen in any of the patients treated with atenolol. Our study supports previous findings that atenolol is at least as effective as propranolol for treatment of IHs and poses less risk of bronchospasm. Our SCAMP proposes guidelines for dosing and monitoring parameters. © 2017 Wiley Periodicals, Inc.

Class 3 semaphorins were discovered as a family of axon guidance molecules, but are now known to be involved in diverse biologic processes. In this study, we investigated the anti-angiogenic potential of SEMA3E and SEMA3F (SEMA3E&F) in infantile hemangioma (IH). IH is a common vascular tumor that involves both vasculogenesis and angiogenesis. Our lab has identified and isolated hemangioma stem cells (HemSC), glucose transporter 1 positive (GLUT1 + ) endothelial cells (designated as GLUT1 sel cells) based on anti-GLUT1 magnetic beads selection and GLUT1-negative endothelial cells (named HemEC). We have shown that these types of cells play important roles in hemangiogenesis. We report here that SEMA3E inhibited HemEC migration and proliferation while SEMA3F was able to suppress the migration and proliferation in all three types of cells. Confocal microscopy showed that stress fibers in HemEC were reduced by SEMA3E&F and that stress fibers in HemSC were decreased by SEMA3F, which led to cytoskeletal collapse and loss of cell motility in both cell types. Additionally, SEMA3E&F were able to inhibit vascular endothelial growth factor (VEGF)-induced sprouts in all three types of cells. Further, SEMA3E&F reduced the level of p-VEGFR2 and its downstream p-ERK in HemEC. These results demonstrate that SEMA3E&F inhibit IH cell proliferation and suppress the angiogenic activities of migration and sprout formation. SEMA3E&F may have therapeutic potential to treat or prevent growth of highly proliferative IH. - Highlights: • SEMA3E&F reduce actin stress fibers and induce cytoskeletal collapse in HemEC. • SEMA3E&F inhibit angiogenic activities of HemEC. • SEMA3E&F can interrupt the VEGF-A-VEGFR2-ERK signaling pathway in HemEC. • Plexin D1 and NRP2 are induced during HemSC/GLUT1 sel -to-EC differentiation

Purpose: To assess knowledge of risk factors and prevention of pressure ulcers from the perspective of relatives and caregivers of patients with spinal cord injury at home.

Method: cross-sectional, descriptive, quantitative study. The sample was made up by 50 people. Data were collected through a questionnaire in August and December 2008. The statistical analysis was performed using SPSS Windows, version 13.0.

Results: We found that family caregivers have correct knowledge about its role in the prevention, 80% of cases and higher risk patients are bedridden, paraplegic and elderly (74%; patients and relatives should be counseled about the risk factors of pressure ulcers (100%; keeping the skin dry and clean prevents the onset of UP (64%. With regard to cognitive errors, these are related to the periodicity in assessing the integrity of the skin (84% and the use of sheets in the transfer and mobilization of the patient (80%.

Discussion: The high success rate on risk factors shows that families and caregivers have good knowledge: they are prepared to care, meanwhile, the high incidence of errors on pressure ulcers prevention measures shows that relatives and caregivers lack of adequate knowledge of such measures.

Conclusions: Research shows that assessing the knowledge of relatives and caregivers is of the essence to implement corrective actions to suit them to take care of people with spinal cord injury.

Drepper, H

The superficial angiomas and nevi arise from the endothelial cells, the pigment-cell-system or the epidermal cells. Hemangiomas are benign tumours of the endothelial cells appearing predominantly in female newborn infants. Depending on localisation, growth and proliferation there is a tendency for spontaneous involution. For irreversible dysfunction or anatomical deformities surgical resection during the growth phase of the hemangioma is indicated. Surgery may be necessary to improve the functional and esthetic appearance after spontaneous involution causing loose residual skin. Radiotherapy of the lesion is rarely indicated. Systemic steroid therapy in cooperation with the pediatrician should be reserved only for desperate cases such as Kasabach-Merrit-Syndrome. Port wine nevi without scars can be covered with skin tanning cosmetics. Argon-Laser-Therapy is not yet so selective that healing can be achieved with certainty and without scars. Clinical progression requires surgery, especially for racemose angiectasia. Arterial embolization should only be used under special conditions, and then only as pretreatment. Lymphangiomas are mostly angiectatic processes, especially of lymphatic vascular tissue and vessels. Even large cystic lymphangiomas can be treated quite well by surgery, but operations on large diffuse invasive lymphangiomas often cause lymphedema and infection similar to erysipelas leading to pseudorecurrence. The benign malformations of the pigment cell system require clear differentiation from malignant melanoma and its precursors. Malignant melanoma develops more frequently from congenital nevi of the deep type than from other pigmented lesions. Malignant melanomas arising from giant nevi are usually diagnosed too late so that almost all patients die. Removal of giant nevi as early as possible is recommended. The epidermal malformations, too, need accurate diagnosis. Multisymptomatic syndromes such as the Basal-Cell-Nevus-Syndrome, and vascular and

The authors described the results of therapy of 74 spinal hemangioma patients. The patients were divided into 2 groups: 1 - radiotherapy only; 2 - radiotherapy following surgical intervention for enhanced symptoms of spinal compression. γ-beam therapy was given 5 times a week at a single dose of 0.8-1.2 Gy. An integral dose delivered to the cervical spine was 26-32 Gy, to the thoracic spine 28-30 Gy, to the lumber spine - 30-34 Gy. Field sizes varied from 3x4 to 3x12 cm depending on lesion spreading. Therapy also included traction on a special platform bed. An analysis of delayed therapeutic results (from 3 to 13 yrs.) has shown that clinical convalescence with regained working capacity in the 1st group (40 patients) was observed in 21 patients, in the 2nd group (34 patients) - in 5 patients only. Partial functional restoration was observed in both groups (19 patients in each group). The therapy applied was ineffective in 10 patients of the 2nd group

Cavernous sinus hemangioma (CSH) is a rare extra-axial vascular neoplasm that accounts for 2% to 3% of all cavernous sinus tumors. Their location, propensity for profuse bleeding during surgery, and relationship to complex neurovascular structures are factors which present difficulty in excising these lesions. The authors describe their experience of 22 patients with CSH over 14 years at a tertiary care center. Patients were managed with microsurgical resection using a purely extradural transcavernous approach (13 patients) and with Gamma Knife radiosurgery (GKRS; Elekta AB, Stockholm, Sweden) (nine patients). Retrospective data analysis found headache and visual impairment were the most common presenting complaints, followed by facial hypesthesia and diplopia. All but one patient had complete tumor excision in the surgical series. Transient ophthalmoparesis (complete resolution in 6-8 weeks) was the most common surgical complication. In the GKRS group, marked tumor shrinkage (>50% tumor volume reduction) was achieved in two patients, slight shrinkage in five and no change in two patients, with symptom improvement in the majority of patients. To our knowledge, we describe one of the largest series of CSH managed at a single center. Although microsurgical resection using an extradural transcavernous approach is considered the treatment of choice in CSH and allows complete excision with minimal mortality and long-term morbidity, GKRS is an additional tool for treating residual symptomatic lesions or in patients with associated comorbidities making surgical resection unsuitable.

Terminology regarding the vascular lesions of the soft tissues remains confusing. A single classification is necessary in order to decide on the proper investigation and the best treatment. At the Workshop on Vascular Anomalies in Rome in June 1996, the membership accepted the Mulliken and Glowacki classification, which differentiates vascular lesions into vascular tumors, including hemangiomas and vascular malformations. At Sainte-Justine, we have set up a multidisciplinary clinic for the discussion of problem patients with vascular anomalies, both in terms of diagnosis and treatment. In this review, we present our experience regarding the classification, the imaging modalities and the treatment of vascular anomalies. In our experience, Doppler ultrasound should be the initial imaging modality for recognizing vascular tumors from vascular malformations. CT scan or magnetic resonance imaging is best to evaluate the extent of the lesions prior to treatment. A multidisciplinary approach is essential to establish a correct diagnosis and define accordingly the appropriate treatment and follow-up. (orig.)

Before 1974 about 5000 children were irradiated at the Institut Gustave-Roussy for a skin hemangioma of whom 20% were treated with radium applicators. To evaluate the absorbed doses to these patients at any site, we have developed a software program which permits simulation of the actual patient and treatment conditions. Part of this software is devoted to constructing an Individual Computerized Tomography Anatomy (ICTA) based on real human transverse slices and auxological tables. From the generated phantom, 160 anatomical sites of epidemiological interest are defined and localized according to a Cartesian co-ordinate system. The gamma doses at all sites from Ra-226 applicators are calculated by an algorithm which permits separation of the radiation paths in air, tissue, and lungs. It includes a correction for attenuation and scatters in infinite and semi-infinite mediums. To evaluate the factor φ(r) for these corrections at any distance or position from the applicator, we have modelled the results from several Monte Carlo simulations. In the range of 1 to 10 cm, the φ(r) values obtained from our model showed good agreement with those obtained by published methods. For several cases, the absorbed doses at points in water and patients from radium applicators estimated by this software, were compared to those measured and estimated at the Karolinska Hospital. The results showed good agreement. (author)

A junção córtico-medular estava indistinta. O exame histologico dos rins revelou múltiplos glomérulos imaturos com núcleo periférico, capilares inaparentes e padrão arbóreo. O córtex renal apresentou túbulos primitivos com epitélio cubóide ou cilíndrico envolvido por mesênquima corado somente pelo alcian blue e não pelo tricrômico de Masson. Foi também observada leve fibrose intersticial na medula renal. Os rins mostravam estruturas em estágio inapropriado de desenvolvimento ou anômalas.

Full Text Available O uso da irrigação por capilaridade na produção de mudas em viveiros pode trazer vantagens ao uso de água e sua utilização adequada requer o conhecimento da capacidade de ascensão de água no meio de crescimento das raízes, atributo pouco estudado. Para avaliar esta condição fundamental, este trabalho tem como objetivo avaliar a ascensão de água em substratos comerciais de coco e pinus, em dois padrões de tamanho de partículas e em duas condições de umidade, para indicar aquele que possua as melhores características físicas para aplicação na irrigação por capilaridade. Utilizou-se o método de ascensão capilar, com colunas desmontáveis de anéis preenchidas com substratos, avaliando-se os seguintes tempos de contato do fundo da coluna com a lâmina de água: 0,25, 0,5, 1, 2, 4, 8, 16 e 24 horas, com 10 repetições por tempo testado. Pelos resultados, observou-se que a maior ascensão capilar acumulada em 24 horas de ensaio foi obtida para os substratos de textura fina de coco e de pinus. Além disso, a hidrofobia do substrato de coco seco recomenda que as irrigações nesse material devem ter frequências maiores que substratos de pinus, evitando seu secamento. O substrato de pinus, por não apresentar esse comportamento, deve ter turnos de rega mais espaçados, principalmente sob textura fina. Devido à sua maior retenção de água e capacidade de elevação de água quando umedecido, o substrato fino de coco é mais adequado à irrigação por capilaridade em recipientes como tubetes.The capillary irrigation in nursery production could give advantages in water use and its correct application demands knowledge about capillary water rise through root growth media, an attribute poorly studied. This research had as objective to evaluate water capillary rise in commercial pine and coconut substrates for two particle size distributions and two moisture conditions, to indicate the substrate with the best physical

Full Text Available CONTEXTO: A angiogênese terapêutica é uma modalidade de tratamento para pacientes com insuficiência arterial crônica que não têm indicação para revascularização direta ou angioplastia e que não tiveram uma resposta satisfatória ao tratamento clínico. Entre as drogas utilizadas para essa finalidade está a prostaglandina E1 (PGE1. OBJETIVO: Estudar os aspectos morfológicos na gênese de capilares sanguíneos em músculo esquelético do membro caudal de ratos submetidos à isquemia sob a ação da PGE1, administrada por via intramuscular (IM ou endovenosa (EV. MÉTODOS: Foram utilizados 48 ratos, linhagem Wistar-UEM, distribuídos aleatoriamente em três grupos de 16, redistribuídos igualmente em dois subgrupos, observados no 7º e 14º dias, sendo um grupo controle onde apenas foi provocada a isquemia no membro, outro com a isquemia e a injeção da PGE1 via IM e outro com a isquemia e a injeção da PGE1 EV. Para análise dos resultados, foram realizadas a coloração com hematoxilina e eosina (HE e coloração imuno-histoquímica. RESULTADOS: Constatou-se um aumento estatisticamente significativo no número de capilares nos subgrupos com o uso da PGE1 IM e EV, através da contagem nos cortes corados com HE. A imunomarcação não foi eficiente para a quantificação dos capilares. CONCLUSÕES: A PGE1, administrada por via IM ou EV, promoveu, após 14 dias de observação, um aumento no número de capilares no músculo esquelético de ratos submetido à isquemia, identificáveis histologicamente com a coloração em HE. A imunocoloração não permitiu estabelecer uma correlação com o aumento de vasos encontrados na coloração com HE.BACKGROUND: Therapeutic angiogenesis is a treatment modality for patients with chronic arterial insufficiency who do not have indication for direct reconstruction or angioplasty and who were not successfully submitted to clinical treatment.

OBJECTIVE Cavernous sinus hemangiomas (CSHs) are rare vascular tumors. A direct microsurgical approach usually results in massive hemorrhage and incomplete tumor resection. Although stereotactic radiosurgery (SRS) has emerged as a therapeutic alternative to microsurgery, outcome studies are few. Authors of the present study evaluated the role of SRS for CSH. METHODS An international multicenter study was conducted to review outcome data in 31 patients with CSH. Eleven patients had initial microsurgery before SRS, and the other 20 patients (64.5%) underwent Gamma Knife SRS as the primary management for their CSH. Median age at the time of radiosurgery was 47 years, and 77.4% of patients had cranial nerve dysfunction before SRS. Patients received a median tumor margin dose of 12.6 Gy (range 12-19 Gy) at a median isodose of 55%. RESULTS Tumor regression was confirmed by imaging in all 31 patients, and all patients had greater than 50% reduction in tumor volume at 6 months post-SRS. No patient had delayed tumor growth, new cranial neuropathy, visual function deterioration, adverse radiation effects, or hypopituitarism after SRS. Twenty-four patients had presented with cranial nerve disorders before SRS, and 6 (25%) of them had gradual improvement. Four (66.7%) of the 6 patients with orbital symptoms had symptomatic relief at the last follow-up. CONCLUSIONS Stereotactic radiosurgery was effective in reducing the volume of CSH and attaining long-term tumor control in all patients at a median of 40 months. The authors' experience suggests that SRS is a reasonable primary and adjuvant treatment modality for patients in whom a CSH is diagnosed.

Stereotactic radiosurgery is a controversial treatment modality in the management of cerebral cavernous hemangiomas (CHs), and results vary from center to center. Even the interpretation of treatment failure is controversial. It is suggested that the systematic pathological investigation of irradiated specimens could help to resolve the controversy. A hemorrhagic lesion in the posterior part of the thalamus had been diagnosed as a tumor and was treated with 40-Gy fractionated radiotherapy. One year after this treatment the case was reconsidered based on new imaging evidence, and the lesion was removed by conventional craniotomy. Histopathological examination revealed a CH with postirradiation changes. Compared with nonirradiated control CH tissue samples, there was endothelial cell destruction and marked fibrosis with scar tissue formation in the stroma of the treated lesion. The histopathological findings in this specimen were similar to those described in arteriovenous malformations after gamma knife surgery. The results of light microscopic investigations suggest that the ionizing effect of radiation energy evokes vascular and connective tissue stroma changes in CHs as well.

The objective of the present study is to formulate and characterize propranolol hydrochloride (PPL · HCl) gel, and to evaluate the efficacy of this formulation in transdermal treatment for superficial infantile hemangioma (IH). The transdermal PPL · HCl gel was prepared by a direct swelling method, which chose hydroxypropyl methylcellulose (HPMC) as the matrix and used terpenes plus alcohols as permeation enhancer. Permeation studies of PPL · HCl were carried out with modified Franz diffusion cells through piglet skin. Our results pointed to that among all studied permeation enhancers, farnesol plus isopropanol was the most effective combination (Q24, 6027.4 ± 563.1 μg/cm(2), ER, 6.8), which was significantly higher than that of control gel (p homemade PPL · HCl oral solution as a control. Clinical studies also confirmed the excellent therapeutic response and few side effects of the PPL · HCl gel. These results suggest that transdermal application of the PPL · HCl gel is an effective and safe formulation in treating superficial IH.

Combined lymphangioma and hemangioma of the spleen in a patient with Klippel–Trénaunay syndrome

Full Text Available Introduction. Klippel–Trénaunay syndrome (KTS is a very rare congenital anomaly of blood vessels, characterized by the following clinical triad: varicose superficial veins, port-wine stain and usually bony and soft tissue hypertophy of extremities, most often located in the lower extremities. It is often accompanied by visceral manifestations, and rarely combined with splenomegaly. Case Outline. A 30-year-old female patient came to the Surgery Clinic because of occasional left hypochondrial pain. After she was diagnosed with KTS combined with splenomegaly, splenectomy was performed. Macroscopic and microscopic spleen examination indicated the presence of tumor of vascular origin, presenting a combination of lymphangioma and hemangioma. Conclusion. Diagnosed KTS demands a thorough clinical examination of the patient because of the potential presence of visceral manifestations. When splenomegaly is present, even though being often benign, splenectomy is usually performed to alleviate accompanying symptoms which occur as a result of organ enlargement and compression, to prevent rupture and consequential bleeding when the vascular spleen tumor is large, and finally to avoid a possibility of malignant transformation.

Hobnail hemangioma reclassified as superficial lymphatic malformation: a study of 52 cases.

Hobnail hemangioma (HH) is currently classified as a benign vascular tumor, although it is not well understood whether this lesion differentiates toward blood or lymphatic endothelial cells. Immunostaining with the endothelial marker Wilms tumor 1 (WT1) helps distinguish between vascular neoplasms and malformations, being positive in the former and negative in the latter. We sought to investigate WT1, human herpesvirus 8 latent nuclear antigen, D2-40, and Ki-67 immunoprofile in HH, to gain further insight into its histogenesis. We evaluated 52 HHs collected in Dermatohistopathologische Gemeinschaftslabor, Friedrichshafen, Germany. Immunohistochemical expression of WT1 was performed in all cases. Ten of 52 lesions were also studied for D2-40 and Ki-67 staining and 12 lesions were stained for human herpesvirus 8 latent nuclear antigen. All 52 HHs were completely negative for WT1 immunostaining. Immunohistochemistry performed in 10 HHs showed diffuse and strong positive staining for D2-40 in 8 lesions and focal positivity in two. All cases tested showed negative staining for Ki-67 and human herpesvirus 8 latent nuclear antigen. There are no limitations. Although the exact histogenesis of HH is unknown, most of the performed immunohistochemical studies support a lymphatic line of differentiation. However, on the basis of the WT1 negativity, we believe that HH is better considered as a lymphatic malformation rather than a lymphatic neoplasm.

Infantile hemangiomas (IHs) are the most common vascular tumors in children. Because of their benign character and natural involution, the vast majority of IHs do not require any treatment. In the past few years, topical beta blockers have been reported to be an effective treatment of superficial IHs. We sought to evaluate the clinical effectiveness and safety profile of topical propranolol 4% gel for the treatment of IHs. A retrospective study of all cases of IHs treated with topical propranolol 4% gel between 2013 and 2015 was performed. All patients were evaluated in a pediatric dermatology unit of a tertiary medical center. Epidemiologic, clinical, and treatment data, including effectiveness score and safety, were reviewed. The study included 63 patients with a total of 75 IHs. Of the total number of IHs, 43 (57.3%) showed a good response to treatment, 19 (25.3%) a partial response, and 13 (17.33%) poor or no response, thus 62 (82.6%) had good or partial response to treatment. Age at treatment initiation, treatment time, thickness of the superficial component, and size of the lesions were shown to predict response to therapy. Out of the entire examined group, only two patients reported minor local side effects manifested by irritation, redness, and scaling of the treated area. No systemic adverse effects were reported. This is an uncontrolled retrospective study. Propranolol 4% gel is a safe and efficient topical therapy for IH. © 2017 The International Society of Dermatology.

ObjectiveIn patients that require treatment for hepatic giant cavernous hemangiomas (GCH), radiofrequency ablation (RFA) has been suggested to represent a safe and effective alternative to invasive surgery. In a recent report of bipolar RFA, using two expandable needle electrodes, was uneventfully performed in patients with large GCH (>10 cm). The objective of this report is to present two cases in which bipolar RFA of symptomatic GCH was complicated by acute kidney injury.Materials and methodsIn 2015 we treated two patients for very large symptomatic GCH (15.7 and 25.0 cm) with bipolar RFA during open laparotomy.ResultsIn both patients the urine showed a red–brown discoloration directly after the ablation. They became anuric and presented with progressive dyspnea, tachypnea, and tachycardia, requiring hemodialysis for a period of 1 month in one case. Lab results revealed hemepigment-induced acute kidney. Both patients fully recovered and both showed a complete relief of symptoms at 3 months following the procedure.ConclusionRFA for large GCHs can cause hemepigment-induced acute kidney injury due to massive intravascular hemolysis. The presented cases suggest that caution is warranted and advocate an upper limit regarding the volume of GCHs that can be safely ablated.

An asymptomatic 48-year-old man presented with multiple aneurysms in a primary racemose hemangioma of the right bronchial artery. Bronchial arteriography revealed a tortuous artery with four fusiform aneurysms of varying sizes and aneurysmal dilatation with marked thrombus formation in the long segment of the distal portion. Because the tip of catheter could not pass beyond the aneurysmal dilatation, we performed balloon-occluded embolization using a mixture of N-butyl-2-cyanoacrylate (NBCA) and iodized oil. For four other aneurysms, we performed embolization using a coil alone or with NBCA. After 6 months, right bronchial arteriography revealed no enhancement of the aneurysms. Despite the rarity of this procedure, embolization with NBCA is a good option for bronchial artery aneurysm embolization.

A case report and a discussion of recent published data. To highlight the importance of vertebral hemangioma (VH) as a differential diagnosis in the evaluation of locally aggressive spinal lesions. VH commonly occur as incidental findings, however, locally aggressive VH have been described. Difficulties in diagnosing these lesions are well reported and relate to changes in fat content causing uncharacteristic appearances on imaging. The management options for these lesions include a combination of observation, embolization, sclerotherapy, surgical decompression, or stabilization and radiotherapy. A 45-year-old patient who was previously well presented with back pain and rapidly progressive paraparesis. Imaging confirmed the presence of an extensive lesion centered within the right T3 vertebral pedicle with intrusion into the spinal canal. Urgent surgical decompression was undertaken and was complicated by extensive intraoperative hemorrhage requiring massive transfusion. Histologically, the lesion was shown to be a cavernous VH with no evidence of malignancy. Following radiation oncology review, he was offered adjuvant radiotherapy to minimize the risks of recurrence. He achieved a near full neurologic recovery within 2 weeks and had a full recovery by 12 months. VH should be considered in the evaluation of locally aggressive spinal lesions. Angiography is a useful adjunct in the evaluation of these lesions, both as a diagnostic and therapeutic tool. After diagnosed correctly a wide range of treatment options exist that may prevent the patient from undergoing major surgical resection and reconstruction procedures, which may be associated with high rates of morbidity.

Genetic Analysis of Multiple Endocrine Neoplasia Type 1 ( Leads to Misdiagnosis of an Extremely Rare Presentation of Intrasellar Cavernous Hemangioma as MEN1

Full Text Available BackgroundMultiple endocrine neoplasia type 1 (MEN1 is a rare inherited disorder characterized by the simultaneous occurrence of endocrine tumors in target tissues (mainly the pituitary, endocrine pancreas, and parathyroid glands. MEN1 is caused by mutations in the MEN1 gene, which functions as a tumor suppressor and consists of one untranslated exon and nine exons encoding the menin protein. This condition is usually suspected when we encounter patients diagnosed with tumors in multiple endocrine organs, as mentioned above.MethodsA 65-year-old woman who underwent surgery for a pancreatic tumor (serous cystadenoma 5 years previously was referred to our hospital due to neurologic symptoms of diplopia and left ptosis. Brain magnetic resonance imaging revealed a 3.4-cm lesion originating from the cavernous sinus wall and extending into the sellar region. It was thought to be a nonfunctioning tumor from the results of the combined pituitary function test. Incidentally, we found that she also had a pancreatic tumor, indicating the necessity of genetic analysis for MEN1.ResultsGenomic analysis using peripheral leukocytes revealed a heterozygous c.1621G>A mutation in the MEN1 gene that was previously reported to be either a pathogenic mutation or a simple polymorphism. We pursued a stereotactic approach to the pituitary lesion, and microscopic findings of the tumor revealed it to be an intrasellar cavernous hemangioma, a rare finding in the sellar region and even rarer in relation to oculomotor palsy. The patient recovered well from surgery, but refused further evaluation for the pancreatic lesion.ConclusionThere is great emphasis placed on genetic testing in the diagnosis of MEN1, but herein we report a case where it did not assist in diagnosis, hence, further discussion on the role of genetic testing in this disease is needed. Also, in cases of pituitary tumor with cranial nerve palsy, despite its low prevalence, intrasellar cavernous hemangioma

To systematically review studies of laser treatment of infantile hemangioma (IH). We searched multiple databases including MEDLINE® and EMBASE from 1982 to June 2015. Two investigators independently screened studies against predetermined criteria and extracted key data. Investigators independently assessed study risk of bias and the strength of the evidence of the body of literature. We identified 29 studies addressing lasers: 4 randomized controlled trials, 8 retrospective cohort studies, and 17 case series. Lasers varied across studies in type, pulse width, or cooling materials. Most comparative studies (n = 9) assessed variations of pulsed dye laser (PDL) and examined heterogeneous endpoints. Most studies reported on treatment of cutaneous lesions. Overall, longer pulse PDL with epidermal cooling was the most commonly used laser for cutaneous lesions; Nd:YAG was the most commonly used intralesionally. Most studies reported a higher success rate with longer pulse PDL compared with observation in managing the size of IH, although the magnitude of effect differed substantially. CO2 laser was used for subglottic IH in a single study, and was noted to have a higher success rate and lower complication rate than both Nd:YAG and observation. Studies comparing laser with β-blockers or in combination with β-blockers reported greater improvements in lesion size in combination arms versus β-blockers alone and greater effects of lasers on mixed superficial and deep IH. Strength of the evidence for outcomes after laser treatments ranged from insufficient to low for effectiveness outcomes. Strength of the evidence was insufficient for the effects of laser compared with β-blockers or in combination with β-blockers as studies evaluated different agents and laser types. Studies assessing outcomes after CO2 and Nd:YAG lasers typically reported some resolution of lesion size, but heterogeneity among studies limits our abilities to draw conclusions. Studies of laser

Full Text Available O aumento da incidência de traumas de alta energia esta relacionado com o crescimento da prevalência de lesões raquimedulares ocasionando seqüelas motoras nos membros. O programa de reabilitação proporciona perspectiva de melhora da qualidade de vida, colaborando para a reintegração social desses indivíduos. As síndromes dolorosas dos ombros são freqüentes nos pacientes lesados medulares, independentemente do programa de reabilitação adotado. No presente estudo, avaliou-se por meio da ultrassonografia, 32 ombros de 16 pacientes com lesão medular com localização anatômica entre C4 e T12, em reabilitação no DOT/HC-UNICAMP, constatando-se alterações nos tendões dos músculos do manguito rotador em 46,88% e nas tuberosidades umerais em 12,50% dos pacientes estudados. As alterações foram mais prevalentes entre os tetraplégicos. A execução de medidas analgésicas, fortalecimento dos músculos do manguito rotador quando possível e alterações posturais podem significar diminuição na ocorrência das síndromes dolorosas dos ombros, melhorando o aproveitamento do programa de reabilitação e com ganhos na qualidade de vida.The increasing incidence of high energy traumas is associated to a growing prevalence of spinal cord injuries causing motor sequels on limbs. Rehabilitation programs provide an opportunity for improvement of quality of life, helping on integrating those individuals back into social activities. Shoulder pain is more frequent in individuals with spinal cord injury, regardless of the rehabilitation program adopted. In the current study, 32 shoulders of 16 patients with spinal cord injury levels between C4 and T12 submitted to a rehabilitation program at DOT/UNICAMP were evaluated by using ultrasound. Changes on rotator cuff tendons were detected in 56.25%, and 12.50% of the patients presented changes in humeral tuberosities. These changes were more prevalent in quadriplegic patients.

Full Text Available O objetivo do trabalho foi identificar e quantificar o formaldeído presente em formulações comerciais de alisamento capilar, sendo abordada a aplicação da cosmetovigilância a partir de ensaios organolépticos/físico-químicos e análise dos rótulos. Oito formulações comerciais de marcas distintas foram submetidas à análise por espectrofotometria, baseado na reação entre formaldeído e ácido cromotrópico na presença de sulfato de magnésio, produzindo um complexo que permite identificar e quantificar a presença da substância ativa. As amostras A1, A3, A5 e A8 apresentaram uma concentração de formaldeído variando de 1,5 a 3,83% (p/v, o que corresponde a concentrações 7,5; 16,45; 7,9 e 19,15 vezes acima do permitido pela ANVISA, apresentando odor forte característico dessa substância ativa. Destas amostras, A3 e A5 não indicaram a presença de formaldeído no rótulo, além de ignorarem as informações de advertência e restrições de uso. Foi verificado ainda, a ausência do número de registro concedido pela ANVISA para a amostra A5, o que pode ser indício de produto clandestino. Quanto às características organolépticas e físico-químicas somente a amostra A2 apresentou resultados de viscosidade e centrifugação diferentes das demais. Diante desses resultados, conclui-se que 50% dos produtos analisados foram reprovados devido à presença de formaldeído fora da concentração permitida, ficando evidente a importância da implantação do sistema de cosmetovigilância para garantir a qualidade final dos produtos cosméticos, tendo em vista principalmente, a segurança e eficácia desses produtos.Palavras-chaves: Alisamento capilar.

Objective: To correct the misunderstanding that arteriovenous shunts (AVS) are rarely found in adult cavernous hemangiomas of the liver (CHL) and to increase its diagnosis rate by DSA. Methods: DSA examination and DSA images of thirty adults with definitely diagnostic CHL and without evidence of other hepatic diseases and hepatic injury were analyzed retrospectively. X-ray films of 21 cases with AVS taken immediately after transcatheter arterial embolization using lipiodol (L-TAE) were compared with the corresponding DSA images to check up those AVS opacified in DSA by observing sediment and distribution of iodized oil injected. Results: Definite diagnosis of AVS by DSA were obtained in 22 cases of this series (73%). All the AVS were located in the peritumoral parenchyma and appeared as parallel track sign, and early opacification of small draining veins, etc. during arterial phase of DSA. X-ray films taken immediately after L-TAE in 21 of 22 cases with AVS showed that few portal radicles or draining veins were refilled by iodized oil through incompletely occluded shunts in 11 cases, and no any vein was refilled by iodized oil resulted from complete occlusion of the present AVS in 10. No definite AVS was found in the other 8 cases of this series, and in 6 of them improper imaging factors of DSA were used. Conclusion: This study serves to emphasize that AVS is not a diagnosis of hepatic malignancy, but is frequently seen in the commonly benign CHL of adults. Proper imaging factors of DSA and superior images can be helpful to opacify small AVS of CHL. The formation of AVS in CHL may be closely related to the pathological changes of peritumoral parenchyma, however, its mechanism must be further studied

In 35 cases of hepatocellular carcinoma (HCC) and 25 cases of cavernous hemangioma (CH) of the liver, magnetic resonance (MR) spin echo images were obtained using a 0.35 tesla superconducting MR imager (Siemens, Magnetom). On the images with a TR (repetition time) of 1600 msec and a TE (echo delay time) of 70 msec, all tumors appeared as high intensity areas, and there, Tumor/Liver intensity ratio (T/L) was calculated. T/sub 1/ (longitudinal relaxation time) and T/sub 2/ (transverse relaxation time) of the lesions were also calculated from the images with two TR (400 and 1600 msec) and two TE (35 and 70 msec). The T/sub 1/(940 +- 180 msec), T/sub 2/(110 +- 40 msec) and T/L(2.2 +- 0.4) of CH were significantly higher (p<0.001) than the T/sub 1/(660 +- 100 msec), T/sub 2/(60+-8 msec) and T/L(1.5 +- 0.4) of HCC, respectively. There was no correlation between these values and tumor size on MR, which ranged from 1.5 to 10 cm in diameter. All of CH satisfied the condition; T/sub 1/>660 msec, T/sub 2/>54 msec and T/L>1.6. In contrast, 73% of HCC did not satisfy the above condition. Our results suggest that use of MR will improve the accuracy of the differential diagnosis of HCC and CH.

Objective: To analyze the factors that might affect the therapeutic results of pingyangmycin-lipiodol emulsion intra-arterial sclerosing embolization (PLE-IASE) in treating symptomatic cavernous hemangioma of liver (SCHL). Methods: PLE-IASE was performed in 89 patients with SCHL (32 males and 57 females). Before treatment the mean diameter of the hemangioma was (8.3±3.8) cm. Of 89 patients, 53 experienced anxiety, 35 suffered from right upper abdominal pain and the remaining one developed Kasabach-Merrit syndrome. Before PLE-IASE, the arteriographic classification was conducted based on hepatic arteriographic findings. Then pingyangmycin-lipiodol emulsion (PLE) was injected through the feeding artery. The dosage of pingyangmycin (PYM) was (9.8 ± 4.4) mg and the dosage of lipiodol (LP) was (5.9 ± 2.9) ml. The lipiodol deposition status was judged by the follow-up spot film taken immediately after PLE-IASE. The observations of the occurrence of complications, the relief of symptoms and the minification of SCHL were followed for 6-72 months after PLE-IASE. The linear regression analysis statistics was conducted by taking the minification as dependent variable and taking the arteriographic classification, lipiodol deposition status, the dosage of PYM, the dosage of lipiodol and the preoperative SCHL diameter as independent variable. Results: Of all 89 cases of SCHL, hypervascular type was seen in 51, hypovascular type in 26 and arteriovenous shunt (AVS) type in 12. Good lipiodol deposition status was found in 64 patients and poor deposition in 25 patients after PLE-IASE. After PLE-IASE, the symptom of anxiety in 53 patients was relieved and the right upper abdominal pain was reduced in 33 cases although intermittent pain still remained in 2 patients. The blood platelet count of the patient with Kasabach-Merrit syndrome returned to normal after the treatment. The symptomatic relieve rate was 98.7%. No serious complications occurred in the follow-up period. The linear

Purpose: To evaluate the therapeutic effect and safety of pingyangmycin-lipiodol emulsion (PLE) intra-arterial embolization for treating gigantic cavernous hemangioma of the liver (CHL).Methods: Three hospitals (Nanfang Hospital, Inner Mongolia Autonomous Region's Hospital and Huai He Hospital) participated in the study during 1997-2001. A total of 98 patients with CHL were embolized with PLE via the hepatic artery. The therapeutic effects including changes in tumor diameter, symptomatic improvement and occurrence of complications were evaluated for a period of 12 months after the procedure.Results: The tumor diameters decreased significantly from 9.7 ± 2.3 cm to 5.6 ± 1.6 cm 6 months after the treatment (P < 0.01), and then to 3.0 ± 1.2 cm at 12 months (P < 0.01). Transient impairment of liver function was found in 77 cases after embolization, 69 cases of which returned to normal in 2 weeks, and the other eight cases of which recovered 1 month later. The clinical symptoms were significantly relieved in all 53 symptomatic patients. Persistent pain in the hepatic region was found in two cases, and these two patients resorted to surgery eventually.Conclusion: Intra-arterial PLE embolization proves to be effective and safe in treating patients with CHL

Conocemos los datos económicos de otros países como EE.UU. o Reino Unido, pero consideramos que estas aportaciones no son asimilables a nuestro país. Por eso queremos analizar este aspecto desde el Hospital Nacional de Parapléjicos (HNP, ya que es un hospital monográfico dedicado al tratamiento de las UPP en pacientes lesionados medulares, y aportar así un poco de luz en este campo. Hemos llegado a la conclusión de que el gasto total en España por causa de las UPP se cifra en torno a los 600 millones de euros anuales, calculados con precios de costes de 2011, cifra muy inferior a la de otros países quizás por sus elevados costes o porque éstos incluyan otras patologías además de las UPP en lesionados medulares, otras subpoblaciones de pacientes o incluso la universalidad de cualquier tipo de herida. En las circunstancias económicas actuales, hay que considerar la prevención como un pilar fundamental para evitar este excesivo gasto que casi siempre, es debido a una irregular praxis sanitaria.Currently there is no economic studies in Spain reflecting the cost of the therapy in a pressure ulcer (PU.

To study the clonality of polygonal cells and surface cuboidal cells in the so-called pulmonary sclerosing hemangioma (PSH). 17 female surgically resected PSH were found. The polygonal cells and surface cuboidal cells of the 17 PSH cases were microdissected from routine hematoxylin and eosin-stained sections. Genomic DNA was extracted, pretreated through incubation with methylation-sensitive restrictive endonuclease HhaI or HpaII, and amplified by nested polymerase chain reaction for X chromosome-linked androgen receptor (AR) and phosphoglycerate kinase (PGK) genes. The length polymorphism of AR gene was demonstrated by denaturing polyacrylamide gel electrophoresis and silver staining. The PGK gene products were treated with Bst XI and resolved on agarose gel. Amongst the 17 female cases of PSH, 15 samples were successfully amplified for AR and PGK genes. The rates of polymorphism were 53% (8/15) and 27% (4/15) for AR and PGK genes respectively. Polygonal cells and surface cuboidal cells of 10 cases which were suitable for clonality study, showed the same loss of alleles (clonality ratio = 0) or unbalanced methylation pattern (clonality ratio < 0.25). The polygonal cells and surface cuboidal cells in PSH demonstrate patterns of monoclonal proliferation, indicating that both represent true neoplastic cells.

SH is thought to evolve from primitive respiratory epithelium and mostly shows benign biological behavior; however, cases of lymph node metastases, local recurrence and multiple lesions have been described. Case Presentation We report the case of a 21-year-old Caucasian male with a history of locally advanced and metastatic rectal carcinoma (UICC IV; pT4, pN1, M1(hep that was eventually identified as having hereditary non-polyposis colorectal cancer (HNPCC, Lynch syndrome. After neoadjuvant chemotherapy followed by low anterior resection, adjuvant chemotherapy and metachronous partial hepatectomy, he was admitted for treatment of newly diagnosed bilateral pulmonary metastases. Thoracic computed tomography showed a homogenous, sharply marked nodule in the left lower lobe. We decided in favor of atypical resection followed by systematic lymphadenectomy. Histopathological analysis revealed the diagnosis of SH. Conclusions Cases have been published with familial adenomatous polyposis (FAP and simultaneous SH. FAP, Gardner syndrome and Li-Fraumeni syndrome, however, had been ruled out in the present case. To the best of our knowledge, this is the first report describing SH associated with Lynch syndrome.

Cryotherapy is the application of varying extremes of cold temperatures to destroy abnormal tissue. The intent of this article is to describe a novel technique using percutaneous cryotherapy for treating a noninvoluting congenital craniofacial hemangioma (NICH). An 18-year-old woman with type 1 von Willebrand’s disease, as well as a qualitative platelet aggregation disorder, presented with multiple recurrent episodes of oral bleeding from a NICH involving the right buccal space and maxillary tuberosity. The patient was initially treated with a combination of endovascular particulate embolization, percutaneous sclerotherapy, tissue cauterization, and laser therapy between the ages of 4 and 8 years of age. At 18 years of age, the patient presented with recurrent episodes of oral bleeding related to the NICH. Endovascular embolization was performed using particulate and a liquid embolic agent with limited success. Due to the refractory nature of this bleeding, the patient underwent successful lesion ablation using percutaneous cryotherapy. At 9-month follow-up, the patient is asymptomatic with no episodes of recurrent bleeding.

Involuted infantile facial hemangiomas (IHs) may adversely affect the social skills of children. To assess the social impact of involuted facial IHs, with or without prior treatment, in preteen children. An observational, cross-sectional study of social anxiety and skills in preteen children with facial IHs diagnosed during infancy. The study took place in an academic institution and a community dermatology practice between January 1, 2013, and July 30, 2014. Records on 236 children with IHs located in a cosmetically sensitive area were identified; of those, 144 potential participants (parents) were reached by telephone and mailed study packets. Thirty completed questionnaires were returned. Data analysis was performed from August 1, 2014, to September 7, 2015. The questionnaires included the following psychiatric scales: (1) Social Anxiety Scale for Children-Revised (SASC-R), completed by parents and children, including the domains of Fear of Negative Evaluation and Social Avoidance/Distress in New Situations (SAD-New) (higher scores indicate greater social anxiety), and (2) Social Competency Inventory (SCI), completed by parents, including the domains of Prosocial Behavior and Social Initiative (lower scores indicate poorer social competency). Demographics, clinical details, and survey responses were collected. Analysis was conducted using t tests to compare scores for each survey domain with established normative data and between sex as well as between treatment vs nontreatment groups. Of the 144 potential participants, 30 (21%) responded. The mean age of the preteen subjects was 10.0 years (range, 5.4-12.9 years) with a 2:1 female to male ratio. Twenty-five children (83%) had a single IH, and the remaining 5 participants (17%) had multiple IHs, with at least 1 IH in a cosmetically sensitive area. The periocular region was the most common site of the IH (10 [33%]), followed by the nose (6 [20%]), cheek (5 [17%]), forehead (4 [13%]), lip or perioral region (4 [13

Lichen planopilaris is a cicatricial alopecia that causes permanent destruction of hair follicles. We report two cases of post-transplantation lesions compatible with lichen planopilaris in both recipient and donor areas. The quality of the hair follicles in the donor area was apparently compromised by lichen planopilaris, the probable cause of hair loss. Similar reports are rare. When lichen planopilaris is suspected, a biopsy of the scalp must be performed to avoid transplantation during disease activity.

The difference between liver hemangioma and metastases is a subject of clinical interest. Nineteen MR liver studies are presented, 10 of them correspond to hemangiomas and 9 to metastases. In all cases, intravenous gadolinium was used in dynamic slices with T1-weighted gradient echo sequences. Late uptake is studied in two lesions. One minute postinjection, the periphery appears hyperintense (more so than the fatty tissue) in 7 out of the 10 cases of hemangioma; in 4 cases, the metastases show less intense uptake than fatty tissue. From two and a half minutes on, the periphery is hyperintense (more so than the fatty tissue) in all the hemangiomas, while in 4 metastases, the periphery is hyperintense (but less so than the fatty tissue), and the rest of the metastases remain hypo-isointense. Uptake by the hemangiomas at two hours reveals the isointense lesion with the liver. In conclusion, at approximately one minute postinjection, hemangiomas show very marked and nodular uptake, with centripetal progression; the hypersignal persists in late slices. However, the metastases present variable, moderate, irregular uptake at the beginning, with no central progression and reduced contrast in the late slices at 5 minutes. In some cases, Gd-DTPA increases the diagnostic certainty, improving reliability with respect to conventional MR. (Author)

We evaluated the clinical, plain radiographic, and angiographic findings of congenital vascular malformation of the soft tissue. Retrospective analysis was performed in 36 patients. Pathological diagnosis was done in 25 patients by surgery and the others were clinically and angiographically diagnosed. On the basis of angiographic findings, we classified the lesions to three groups as arteriovenous malformation (AVM), hemangioma, and venous malformation. In pathologically proven 25 cases, we compared the angiographic diagnosis with the pathologic diagnosis. By angiographic classification, AVM was 13 cases, hemangioma 16 cases, and venous malformation 7 cases. The locations of the lesions were upper extremities in 14 cases, lower extremities in 20 cases, both extremities in 1 case, and back in 1 case. Clinical findings were bruit and thrill in 13 cases(12 AVMs,1 hemangioma) and varicosities in 16 cases(11 AVMs, 3 hemangiomas and 2 venous malformations). The varicosities in AVM were pulsating nature, but not in hemangioma and venous malformation. The concordance rate of the angiographic and pathologic diagnosis was 100%(6/6) in AVM, 71%(10/14) in hemangioma and 60% (3/5) in venous malformation. We think that angiography is an essential study for accurate diagnosis and appropriate treatment of congenital vascular malformation

The use of indium-111 oxine platelet scintigraphy and survival studies in pediatric patients with thrombocytopenia

Castle, V.P.; Shulkin, B.L.; Coates, G.; Andrew, M.

1989-01-01

We have utilized 111 In-labeled heterologous platelets to investigate the mechanism of thrombocytopenia in ten children. From the scintigraphic findings, platelet survival times, and clinical information, thrombocytopenia was ascribed to decreased production or to increased destruction. Two patients were found to have bone marrow production defects. Two patients with hemangiomas were studied. In one, the hemangioma was shown not to be the cause of thrombocytopenia. In the second, the hemangioma was proven the source of platelet destruction, but was much more extensive than clinically evident. In both, surgical manipulation of the hemangioma was avoided. Six additional patients had thrombocytopenia due to accelerated destruction. In four, the spleen was shown responsible. In two, however, the spleen was shown not to be responsible for the low platelet counts, and splenectomy was avoided. Thus, 111 In-platelet scintigraphy and survival studies are valuable in the classification and management of childhood thrombocytopenia. We believe that this study should be performed, when possible, in any child with thrombocytopenia where the mechanism is unclear or the therapeutic intervention involves splenectomy or resection of a hemangioma

Los datos fueron comparados con controles. Se correlacionaron con las deterniinaciones bioquímicas y con el tiempo de exposición al tóxico. Por encima dei limite superior control, se encontro el ingreso medular en tres pacientes, el arribo cortical en cuatro y el TCC en tres. Los valores de N13,N20 y TCC no mostraron correlación con los parâmetros bioquímicos ni con el tiempo de exposición al tóxico. Estos hallazgos sugieren que, si bien la neuropatía periférica condiciona el retraso dei ingreso medular y del arribo cortical, es probable que exista también compromiso de la mielina central en algunos de los pacientes crónicamente expuestos.

PELVIS is an acronym defining the association of perineal hemangioma, malformations of external genitalia, lipomyelomeningocele, vesicorenal abnormalities, imperforate anus and skin tag. Eleven cases have been reported according to the Orphanet data. Acronyms of LUMBAR and SACRAL syndrome have been used and most probably represent a spectrum of the same entity. Very little is known about the success and timing of cloacal reconstruction after the treatment of hemangioma. We present a variant of PELVIS syndrome and discuss the possibilities and optimal timing of surgical reconstruction. Female infant was born with persistent cloaca and multiple hemangiomas of genitals, perineal area and left thigh. Colostomy was performed after birth. In order to treat hemangioma and to make the reconstruction of cloaca possible, corticosteroid treatment orally and multiple laser treatments were performed alternating Nd:YAG laser and pulsed dye laser therapy. Cystoscopy confirmed hemangiomatosis in the mucosa of the common channel, bladder neck and septate vagina. Oral propranolol treatment was started at the age of 18 months and continued for 1 year. It induced rapid improvement of hemangiomas. Two more pulsed dye laser treatments were performed to remove residuals of hemangiomas from the perineum and genital area. Posterior sagital reconstruction by separation of the rectum, mobilization of urogenital sinus and vaginal reconstruction was performed with no major bleeding at the age of 4 years. Postoperatively, after a period of progressive rectal dilatation colostomy was closed. Girl is now 6 years old, dry day and night without residual urine and normal upper tracts. Rectal calibration is normal, fecal continence is still to be evaluated but constipation is easily manageable. CT of the spine and the perineum showed sacral dysplasia and spina bifida with lumbo-sacral lipoma and tethering of terminal filum without neurological deterioration at the moment but requiring close

Throughout the years, various classifications have evolved for the diagnosis of vascular anomalies. However, it remains difficult to classify a number of such lesions. Because all hemangiomas were previously considered to involute, if a lesion with imaging and clinical characteristics of hemangioma does not involute, then there is no subclass in which to classify such a lesion, as reported in one of our cases. The recent classification proposed by the International Society for the Study of Vascular Anomalies (ISSVA, 2014) has solved this problem by including non-involuting and partially involuting hemangioma in the classification. We present here five cases of vascular anomalies and discuss their diagnosis in accordance with the ISSVA (2014) classification. A non-involuting lesion should not always be diagnosed as a vascular malformation. A non-involuting lesion can be either a hemangioma or a vascular malformation depending upon its clinicopathologic and imaging characteristics.

Throughout the years, various classifications have evolved for the diagnosis of vascular anomalies. However, it remains difficult to classify a number of such lesions. Because all hemangiomas were previously considered to involute, if a lesion with imaging and clinical characteristics of hemangioma does not involute, then there is no subclass in which to classify such a lesion, as reported in one of our cases. The recent classification proposed by the International Society for the Study of Vascular Anomalies (ISSVA, 2014) has solved this problem by including non-involuting and partially involuting hemangioma in the classification. We present here five cases of vascular anomalies and discuss their diagnosis in accordance with the ISSVA (2014) classification. A non-involuting lesion should not always be diagnosed as a vascular malformation. A non-involuting lesion can be either a hemangioma or a vascular malformation depending upon its clinicopathologic and imaging characteristics

Full Text Available Introduction. Sinusoidal hemangioma is a rare variant of acquired cavernous hemangioma predominantly occurring in females. Very few case reports have been described in the literature. Case Report. We present a case of a 46-year-old woman who noticed a slowly growing, cutaneous nodule on the left breast. Local excision of the lesion was performed and histology allowed to find a sinusoidal hemangioma. No recurrence was noticed. Conclusion. The very few reports of such a lesion in the literature reflect either rarity of such lesions or unfamiliarity of this subset among the pathologists.

Full Text Available A 74 year-old patient with a nocturnal onset of neck and chest pain was brought to an emergency clinic. Physical examination and cardiac assessment were normal. Three hours after the addmittance, a flaccid paralysis of the four limbs supervened. Suspecting of an unusual onset of central nervous system infection, a lumbar puncture was performed, yielding 20 ml of normal cerebrospinal fluid. Thirty oinutes after the puncture, the patient completely regained neurological funcion. He was then referred to a General Hospital where a computed tomography (CT scan was done showing a large cervical epidural bleeding in the posterolateral region of C4/C5 extending to C7/Th1, along with a C6 vertebral body hemangioma. A magnetic resonance imaging revealed the same CT findings. A normal selective angiography of vertebral arteries, carotid arteries and thyreocervical trunk was carried out.

Individuals with PHACE syndrome (posterior fossa malformations, hemangiomas, arterial anomalies, cardiac defects, eye abnormalities, sternal cleft, and supraumbilical raphe syndrome) have reported dental abnormalities to their healthcare providers and in online forums, but dental involvement has not been comprehensively studied. A study was conducted at the third PHACE Family Conference, held in Milwaukee, Wisconsin, in July 2012. A pediatric dentist examined subjects at enrollment. Eighteen subjects were enrolled. The median age was 4.2 years (range 9 mos-9 yrs; 14 girls, 4 boys). Eleven of 18 patients had intraoral hemangiomas and five of these (50%) had hypomature enamel hypoplasia. None of the seven patients without intraoral hemangiomas had enamel hypoplasia. No other dental abnormalities were seen. Enamel hypoplasia may be a feature of PHACE syndrome when an intraoral hemangioma is present. Enamel hypoplasia increases the risk of caries, and clinicians should refer children with PHACE syndrome to a pediatric dentist by 1 year of age. © 2014 Wiley Periodicals, Inc.

Purpose: The efficacy of radiation therapy for Kasabach-Merritt syndrome, which is characterized by a huge hemangioma with consumption coagulopathy, remains controversial. In this study, we retrospectively investigated the treatment outcome of radiation therapy for seven neonates with Kasabach-Merritt syndrome. Methods and Materials: During the past 25 years we have seen seven children with Kasabach-Merritt syndrome who were treated with radiation therapy. Their ages ranged from 1 day to 5 months, with a median age of 1 month. The hemangioma was located in the extremities in four of seven children. Tumor sizes ranged from 70 cm to more than 150 cm in greatest diameter. Initial platelet counts were all less than 40,000/mm 3 except for one patient. In principle, the total dose applied to the hemangioma was 8-10 Gy, with a daily dose of 1 Gy five times a week. Results: Four of seven hemangiomas responded dramatically, with a concomitant rise of the platelet count to radiation therapy. Although the remaining three hemangiomas, all of which were ill circumscribed by widespread overlying shiny, dusky purple skin, became less tense during radiation therapy. Disseminated intravascular coagulopathy was not improved, but they have responded favorably to two or three courses of radiation therapy with an extended radiation field by 1.5 years of age. As a result, all seven patients are now surviving with no evidence of hemangioma or hematological abnormalities. Shortening of the extremity was observed in three patients who received multiple courses of radiation therapy. Conclusions: Radiation therapy appears to be one of the effective treatment options for Kasabach-Merritt syndrome despite the risk of growth delay and malignancy

Objective: To determine the diagnostic efficacy of arterial phase contrast-enhanced ultrasound (CEUS) for characterizing small hepatic nodules (1-2 cm) in patients with high-risk for hepatocellular carcinoma (HCC). Materials and methods: Over 12 months, CEUS was performed in 59 patients at high-risk for HCC with small hepatic nodules (1-2 cm; mean, 1.5 cm). Based only on arterial phase (<45 s) vascular intensity and pattern, lesions were prospectively diagnosed as HCC if there was hypervascularity without known features of hemangioma. The diagnosis of HCC was made regardless of the presence or absence of washout. Verification of diagnosis was made by liver transplantation (n = 13), biopsy (n = 12), resection (n = 3) or clinical and imaging follow-up for at least 12 months (n = 31). Results: At of the time of CEUS, the 59 nodules were diagnosed as HCC in 26 and benign lesions in 33, including 20 regenerative/dysplastic nodules (RN/DN), 11 hemangiomas, and 2 focal fat sparing. All 26 nodules with arterial phase hypervascularity without hemangioma-like features were HCC. However, CEUS misdiagnosed HCC as RN/DN in 4 cases with arterial iso- (n = 3) or hypovascularity (n = 1). CEUS correctly diagnosed all 11 hemangiomas. The sensitivity, specificity, and accuracy of CEUS for diagnosing HCC were 86.7, 100, and 93.2%. Conclusions: Arterial phase vascular intensity and pattern of CEUS are highly accurate for the diagnosis of small (1-2 cm) HCC and hemangioma in liver cirrhosis. On CEUS, arterial phase hypervascularity without a hemangioma-pattern alone may be sufficient for diagnosis of small HCC. Infrequent iso/hypovascular HCC may erroneously suggest RN/DN necessitating biopsy or close follow-up.

Mimics of Duplication Cysts: Intraperitoneal Nodules in a 14-Year-Old Boy

Directory of Open Access Journals (Sweden)

2015-01-01

Full Text Available Hemangiomas are the most common primary hepatic tumors, but there are few reports of their occurrence elsewhere in the abdomen. The concurrent existence of multiple fibrous nodules of the omentum, mesentery, and porta hepatis, along with a gastric hemangioma, in a child raises the question of syndromic association. Our search of the English literature revealed only rare mentions of hemangiomas involving the stomach and mesentery or omentum. These lesions have attracted clinical attention by symptoms of obstruction, gastrointestinal bleeding, intussusception, infection, perforation, or vague abdominal pain. Although some tumors exist unnoticed for many decades and are identified only incidentally, others present emergently and require immediate surgical attention. We report the case of a 14-year-old boy who presented with symptoms similar to those for appendicitis or duplication cyst, who was found to have a torsed gastric hemangioma and multiple benign fibrous nodules in the abdomen. The presence of multiple vascular or fibrous lesions is associated with genetic syndromes that can have lifelong and reproductive repercussions; so it is imperative that these tumors be recognized by diagnosticians.

Reabilitação funcional em lesões vértebro-medulares – A intervenção tradicional e as novas abordagens em fisioterapia

Full Text Available Resumo: Após uma lesão vértebro-medular, em que existe perda da função de diversas estruturas e sistemas do corpo, resultando em limitações da actividade e restrições da participação social, o objectivo final do processo de reabilitação é a reintegração social com o máximo de funcionalidade e qualidade de vida que o tipo e extensão da lesão permitem. Para atingir este estádio, é necessário um período de reabilitação dentro de um equipa multidisciplinar na qual se insere o fisioterapeuta, cujo processo de intervenção varia mediante o tipo e extensão da lesão e a fase clínica em que o utente se encontra. A abordagem da fisioterapia engloba um conjunto de técnicas e procedimentos que podem ser num modelo mais tradicional de intervenção, ou numa perspectiva mais recente relacionada com as terapias de regeneração neuronal. Segundo um modelo tradicional, o processo de intervenção nas lesões completas A e incompletas B visa a restituição da funcionalidade recorrendo ao auxílio de músculos não comprometidos (método compensatório. Nas lesões incompletas C e D visa a reeducação motora dos músculos comprometidos através do estímulo de pontos chave específicos que facilitem o movimento normal dentro de padrões selectivos. Quando se prevê a regeneração neuronal e consequente restituição da função, o processo de intervenção visa a manutenção do trofismo muscular para posterior recrutamento de unidades motoras através de intervenções intensivas. Em ambas as filosofias de intervenção, a evidência científica dos procedimentos não está comprovada devido à escassez dos estudos e à fraca qualidade dos existentes.

To clarify the characteristic sonographic features of benign soft tissue tumors and to evaluate the usefulness of sonographic imaging. We retrospectively reviewed ultrasonographic images of 70 cases in 68 patients with histologically proved benign soft tissue tumors. The tumors include 33 lipomas, 11 hemangiomas, 11 lymphangiomas, 7 neurilemmomas, 4 epidermoid cysts, 2 fibromas, 1 mesenchymoma, and 1 myxoma. The sonographic appearances of the lesions were mainly solid in 53 cases(33 lipomas, 8 hemangiomas, 2 lymphangiomas, 7 neurilemmomas, 2 fibromas and 1 mesenchymoma), mainly cystic in 14 cases(1 hemangioma, 8 lymphangiomas, 4 epidermoid cysts, and 1 myxomal), and mixed in 3 cases(2 hemangiomas and 1 lymphangioma). Although an accurate histologic prediction could not be made in most cases, certain patterns appeared to be characteristic of specific tumor types. 26 cases(78%) of lipoma were seen as lentiform, iso- or hyperechoic, solid mass. Hemangioma had variable appearance and characteristic calcifications were seen in 3 cases. Unicameral or multiseptated cystic mass with variable thickness of echogenic septa and solid portion was the characteristic finding of lymhangioma. Neurilemmoma showed lobulated, oval to round , relatively hypoechoic mass or with without internal cystic portion. Sonographic evaluation of benign soft tissue tumors is useful in demonstrating the location, size, extent, and internal characteristic of the mass. A relatively confident diagnosis can made when the characteristic features of the benign soft tissue tumor are present on sonographic imaging

Full Text Available Purpose: The aim of the study is to improve operative speed and precision of haemangiomas excision. Methods: Case-report: haemangioma is a common affection of the 8% of the population during the neonatal period. In complicated cases and involution sequelae surgical treatment is the first choice. The Authors propose a surgical refinement to prevent intraoperative bleeding. Methods: several suture stitches were placed around the hemangioma. The edges of the lesion became more defined, thus allowing accurate excision. Results and Conclusions: Haemangiomas are characterized by rich blood supply. Surgery is often hindered by massive bleeding and Temporary placement of full-thickness sutures, surrounding the hemangioma, allowed a noticeable improvement in hemostasis precision and greater definition of the margins of the hemangioma.

The purpose of this study was to apply a novel method of multiscale echo texture analysis for distinguishing benign (hemangiomas) from malignant (hepatocellular carcinomas (HCCs) and metastases) focal liver lesions in B-mode ultrasound images. In this method, regions of interest (ROIs) extracted from within the lesions were decomposed into subimages by wavelet packets. Multiscale texture features that quantify homogeneity of the echogenicity were calculated from these subimages and were combined by an artificial neural network (ANN). A subset of the multiscale features was selected that yielded the highest performance in the classification of lesions measured by the area under the receiver operating characteristic curve (A z ). In an analysis of 193 ROIs consisting of 50 hemangiomas, 87 hepatocellular carcinomas and 56 metastases, the multiscale features yielded a high A z value of 0.92 in distinguishing benign from malignant lesions, 0.93 in distinguishing hemangiomas from HCCs and 0.94 in distinguishing hemangiomas from metastases. Our new multiscale texture analysis method can effectively differentiate malignant from benign lesions, and thus has the potential to increase the accuracy of diagnosis of focal liver lesions in ultrasound images

2003-01-01

To describe the imaging findings (MR imaging and angiography) of high-flow vascular anomalies of the tongue, hemangiomas and arteriovenous malformations (AVMs), with emphasis on the discrepant imaging findings in lingual AVMs. Retrospective review of clinical records, histologic reports and imaging studies of five consecutive patients with high-flow lingual vascular anomalies. One patient had hemangioma (aged 1 month) and four patients had AVMs (aged 15 months, 6, 24, and 33 years). Diagnosis was made on the basis of histology in four lesions and was based on typical clinical history in one lesion. MR imaging and angiographic findings of the hemangioma were typical, but similar findings of focal hyperintense mass on T2-weighted images and angiographic stain were seen in three AVMs (patients aged 15 months, 6 and 33 years). On angiography, there was no nidus or direct arteriovenous (AV) shunting in one AVM (patient aged 15 months). The fourth AVM had typical MR imaging and angiographic findings. The imaging findings in lingual AVMs can be atypical or inconclusive and can mimic hemangiomas, especially in the young patient. Since treatment depends on accurate diagnosis, biopsy may be necessary for lesions with inconclusive imaging findings. (orig.)

This paper focuses on the improvement of the diagnostic accuracy of focal liver lesions by quantifying the key features of cysts, hemangiomas, and malignant lesions on ultrasound images. The focal liver lesions were divided into 29 cysts, 37 hemangiomas, and 33 malignancies. A total of 42 hybrid textural features that composed of 5 first order statistics, 18 gray level co-occurrence matrices, 18 Law's, and echogenicity were extracted. A total of 29 key features that were selected by principal component analysis were used as a set of inputs for a feed-forward neural network. For each lesion, the performance of the diagnosis was evaluated by using the positive predictive value, negative predictive value, sensitivity, specificity, and accuracy. The results of the experiment indicate that the proposed method exhibits great performance, a high diagnosis accuracy of over 96% among all focal liver lesion groups (cyst vs. hemangioma, cyst vs. malignant, and hemangioma vs. malignant) on ultrasound images. The accuracy was slightly increased when echogenicity was included in the optimal feature set. These results indicate that it is possible for the proposed method to be applied clinically.

A total of 124 lesions from 1 to 6 cm in diameter, including 31 cavernous hemangiomas, 32 metastases and 61 hepatocellular carcinomas (HCC) were analyzed to study the usefulness of magnetic resonance imaging (MRI) at 0.5 Tesla to differentiate focal hepatic lesions on the basis of qualitative criteria. Each focal hepatic lesion was assessed for shape, internal architecture and signal intensity relative to normal liver parenchyma. While all cavernous hemangiomas and metastases except one lesion could be detected, detection rate of HCC was significantly inferior to that of the other two diseases. A tumor capsule and a hyperintense focus on T 1 -weighted images were demonstrated in only HCC lesions in strong contrast with the other two diseases; however, metastases with slow-growing characteristics or subacute hematoma may appear as similar images. Cavernous hemangiomas appeared markedly hyperintense on T 2 -weighted images in 23 of 31 lesions, but one metastasis and one HCC had similar images. A multivariate analysis of several MRI resulted in the following mean discriminant scores: cavernous hemangioma, -1.2652; metastasis, 0.1830; and HCC, 0.7138. It appeared to be possible to differentiate the three diseases with 84.4 percent accuracy. (author)

The aim of this study was to evaluate capabilities of pulse inversion harmonic imaging (PIHI) in characterization of unifocal liver lesions. We evaluated with PIHI (HDI5000, ATL, Bothell, Wash.) and spiral CT 46 consecutive patients with a single liver lesion identified by fundamental US [7 hepatocellular carcinomas (HCC), 2 cholangiocarcinomas, 7 focal nodular hyperplasias (FNH), 17 hemangiomas and 13 metastases]. The PIHI was performed before and 30 s, 2 and 4 min after bolus administration of Levovist (2.5 g, 300 mg/ml). Scans were digitally stored and reviewed using a dedicated software. Hepatocellular carcinoma was hyperechoic on 30-s scan, and hypoechoic (n = 5) or isoechoic (n = 2) on 2-min scan. Cholangiocarcinoma had inhomogeneous persistent enhancement. Focal nodular hyperplasia was hyperechoic (n = 5) or isoechoic (n = 2) on 30-s scan, hyperechoic (n = 4), isoechoic (n = 2) or slightly hypoechoic (n = 1) on 2-min scan. Large hemangioma revealed peripheral enhancement on 30-s scan which extended centripetally on 2-min scan. Small hemangioma appeared isoechoic on 2-min scan in all but two cases in which they were hypoechoic on 2-min scans and hyperechoic on 4-min scan. Metastasis was hypoechoic on all scans, 70 % with rim enhancement. Similar changes in enhancement pattern have been observed at spiral CT. The 30-s and the 2-min scans revealed a conclusive importance in characterization of HCC, cholangiocarcinoma, and large hemangioma. The 2-min scan often furnished enough information for characterization of small hemangioma and metastasis. The 4-min scan allowed characterization of two hemangiomas which appeared hypoechoic on 2-min scans. In the other cases it did not provide further information. Diagnosis of FNH is usually reached with Colour Doppler US; PIHI should be used when colour Doppler is biased by artefacts or when colour Doppler findings are not characteristic. Our results seem to show that PIHI could be a valuable alternative diagnostic

Objective: To further explore the blood supply and interventional therapy of adult cavernous hemangiomas of the liver (CHL). Methods: Recently some authors reported that a satisfactory effect resulted from transcatheter portal venous embolization was obtained in few cases of CHL with blood supply of portal vein, and raised an objection to the standpoint that CHL was commonly supplied by hepatic artery completely. In order to get a scientific and reasonable explanation for it, this paper reviewed the vascular embryology and histology of the liver, the pathologic features of CHL as well as the relative literature, and combined with the investigation results of blood dynamic changes of CHL that had been performed in 2000-2002 by us. Results: CHL was caused by the arrested development of hepatic sinusoids at the embryonic stage. Pathologically, CHL was consisted of a lot of enlarged abnormal sinusoids,which were variant in size and closely related with the hemodynamic changes of CHL ( in inverse proportion). The CHL consisted of even and tiny abnormal sinusoids (diameter less than 50 μm) pathologically usually presented a high flow. During the hepatic artery angiography or CTHA, it was rapidly filled by the arterial blood containing contrast media and frequently showed dense opacification or enhancement. Simultaneously this could result in increased pressure of abnormal sinusoids. When the sinusoidal pressure exceeded that of the connecting portal venules, the arterial blood containing contrast media filled in the abnormal sinusoids could lead to retrograde flow in the portal venules. That was arterial-portal venous shunts (APVS). These appearances described as above could also occur in some CHL with intermediate flow, in which many tiny abnormal sinusoids located in the peripheral area were identified pathologically. On the contrary, the CHL consisted of larger abnormal sinusoids (diameter more than 500 μm) pathologically usually presented a low flow. During the

Purpose: Cavernous hemangioma of the liver (CHL) is the most common benign solid tumor of the liver. In this study, we quantitative assessment the different degrees of CHL from microscopic viewpoint by using in-line phase-contrast imaging CT (ILPCI-CT). Methods: The experiments were performed at x-ray imaging and biomedical application beamline (BL13W1) of Shanghai Synchrotron Radiation Facility (SSRF) in China. Three typical specimens at different stages, i.e., mild, moderate and severe human CHL were imaged using ILPCI-CT at 16keV without contrast agents. The 3D visualization of different degrees of CHL samples were presented using ILPCI-CT. Additionally, quantitative evaluation of the CHL features, such as the range of hepatic sinusoid equivalent diameters in different degrees of CHL samples, the ratio of the hepatic sinusoid to the CHL tissue, were measured. Results: The planar image clearly displayed the dilated hepatic sinusoids in microns. There was no normal hepatic vascular found in the all CHL samples. Different stages of CHL samples were presented with vivid shapes and stereoscopic effects by using 3D visualization. The equivalent diameters of hepatic sinusoids in three degrees CHL were different. The equivalent diameters of the hepatic sinusoids in mild CHL, range from 60 to 120 µm. The equivalent diameters of the hepatic sinusoids in moderate CHL, range from 65 to 190 µm. The equivalent diameters of the hepatic sinusoids in severe CHL, range from 95 to 215 µm. The ratio of the hepatic sinusoid to the mild, moderate and severe CHL tissue were 3%, 16% and 21%, respectively. Conclusion: The results show that the high degree of sensitivity of the ILPCI-CT technique and demonstrate the feasibility of accurate visualization of different stage human CHL. ILPCI-CT may offers a potential use in non-invasive study and analysis of CHL.

Radiological imaging only reflects the anatomy and its pathological abnormalities. Therefore, the radiologist should be able to recognize the basic features of the pathological anatomy of bone tumors. This can only be learned working closely with a pathologist who is experienced in this field. On the other hand, the pathologist needs from the radiologist their diagnostic assessment with information on size, location, aggressiveness and the existence of a bone tumor's matrix, of the whole lesion, because he usually only receives a small part for examination in the form of a biopsy. In this article, the features and fundamentals (standards) of radiological-pathological cooperation as the mainstay for a precise diagnosis in bone tumors are outlined. The radiological appearance and the histopathological features behind it are presented for Ewing's sarcoma, fibrogenic tumors, giant cell tumor, and hemangioma of the bone. (orig.)

Objective: To investigate the clinical efficacy of "3"2P applicator plus propranolol in children with a large area of skin capillary hemangioma. Methods: Forty five cases of large hemangioma were divided into two groups. Control group of 20 patients recieved the conventional "3"2P application therapy. Of 20 cases in control group, there were 10 cases ≤3 years old children with hemangiomas, and 10 cases > 3 years old children with Port Wine Stain(PWS). Observation group of 25 cases recieved "3"2P applicator plus propranolol. Of 25 cases in observation group 10 cases werer ≤3 years old children with hemangiomas, 15 cases of children with PWS. Comparison was made between two different types of vascular tumors, treatment in ≤3 years old children and > 3 years old children, and adverse reactions. Data statistical analysis used χ"2 test and zero reaction test. P 0.05). The treatment efficacy in ≤3 years old children with infant hemangioma was 90.0% in control group and 100% in observation group (P > 0.05 ). The treatment efficacy for PWS in > 3 years old children was 40.0% in control group and 80% in observation group. Here the difference is statistically significant(P 3 years old children in control group,the treatment efficacy was 90.0% and 40.0%, respectively P 3 years old children in observation group, the treatment efficacy was 100.0% and 80.0% with no significant difference(P > 0.05). Complication of moist dermatitis was 25.0% in control group and 40.0% in observation group. Occurrence of depigmentation was 75.0% and 84.0% in control and observation group with no significant difference(P > 0.05). Changing in heart rate occurs in ≤3 years old children and > 3 years old children, 50.0% and 40.0%, respectively, with no significant difference(P > 0.05). Conclusion: "3"2P applicator plus propranolol treatment of refractory large hemangioma is simple, safe, and effective.

EG-08IDH MUTATIONS IN GLIOMAS ASSOCIATED WITH ENCHONDROMATOSIS

2014-01-01

The enchondromatoses, Ollier's disease and Maffucci syndrome, are non-heritable developmental disorders characterized by multiple enchondromas (Olllier's) in association with hemangiomas (Maffucci). Glial neoplasms are reported in both disorders but a pathogenic mechanism underlying this association has not been identified. We report a case of anaplastic astrocytoma in a 23 year old man with Maffucci syndrome whose tumor carried a substitution mutation of arginine for cysteine at position 132 (R132C) of the isocitrate dehydrogenase 1 (IDH1) protein. This mutation, commonly found in Maffucci-associated enchondromas and hemangiomas, was not detected on routine immunohistochemical (IHC) analysis of the astrocytoma using the R132H mutation-specific antibody, commonly applied in clinical laboratories. The R132C mutation was detected by polymerase chain reaction (PCR) and subsequently confirmed using a SNaPshot assay. Because somatic mosaic IDH mutations are associated with enchondromas and hemangiomas in Maffucci syndrome, we looked for the R132C mutation in a hemangioma, peripheral blood mononuclear cells (PBMNC) and histologically normal brain surrounding the tumor from this patient. The mutation was present in the hemangioma, absent in PBMNC, and present in 2% of alleles in ‘normal’ brain. The low level in surrounding brain tissue is consistent with tumor cell infiltration, not mosaicism, as a S173T p53 mutation in the tumor showed similar results. Using IHC, we further demonstrated that the mutant IDH1 protein in this glioma functions as an oncometabolite. Two repressive histone trimethylation marks were strongly positive in the tumor, supporting a role for 2-hydroxyglutarate in the inhibition of histone demethylation. Together, these data demonstrate that an IDH1 mutation common in enchodromatoses underlies the association of glial tumors reported in both Ollier's disease and Maffucci syndrome.

Adrenal hemangiomas are a rare occurrence. The literature reports only 29 cases that have been treated by surgery. Whereas in about half of these cases CT has been applied for diagnostic evaluation, there are only two cases reporting MRI findings. Since MRI has been gaining in significance for diagnostic examination of adrenal lesions, the communication reports the surgery of an adrenal hemangioma and correlates the pre-operative CT and MRI examinations with the results of the histopathological findings.

MÉTODOS: noventa e três estudos foram identificados no Pubmed, sendo selecionados 11 artigos para análise, 9 experimentais e 2 clínicos, publicados entre 1963 e 2009. Os estudos experimentais apresentaram diferentes formas de tratamento, sendo o desfecho final mensurado pelas diferentes avaliações: funcional, histológica, bioquímica e eletrofisiológica. RESULTADOS: na maioria dos estudos foi observada uma recuperação da função locomotora, histológica e/ou bioquímica. Entretanto, os resultados dos estudos clínicos se mostraram controversos, pelo fato de as amostras serem heterogêneas e a administração da oxigenioterapia hiperbárica ser diferente quanto à dose e o tempo de aplicação. CONCLUSÃO: considerando os resultados desta revisão, será necessária a realização de mais estudos para se ter uma definição sobre a eficácia da oxigenioterapia hiperbárica na lesão medular aguda.

Full Text Available As malformações vasculares periféricas compreendem um espectro de lesões que se tornam aparentes no decorrer da vida e podem ser encontradas em praticamente todo o corpo. São pouco comuns e frequentemente confundidas com o hemangioma infantil. Estas doenças são completamente distintas tanto em relação à história clínica como ao prognóstico e às formas de tratamento. Nestas lesões, a história evolutiva e as características do exame físico são de extrema importância para o adequado diagnóstico clinicorradiológico, que guiará a melhor alternativa terapêutica. As classificações mais recentes dividem as malformações vasculares periféricas levando em consideração o fluxo sanguíneo (alto e baixo e os componentes vasculares envolvidos (arteriais, capilares, linfáticos e venosos. As malformações vasculares periféricas representam um desafio diagnóstico e terapêutico, e exames complementares como tomografia computadorizada, ultrassonografia com Doppler e ressonância magnética, em conjunto com a história clínica, podem trazer informações quanto às características de fluxo e à extensão das lesões. Arteriografia e flebografia confirmam o diagnóstico, avaliam a sua extensão e orientam a decisão terapêutica. Malformações de baixo fluxo geralmente são tratadas por abordagem percutânea e injeção de agente esclerosante, enquanto para as malformações de alto fluxo o acesso é endovascular com uso de agentes embolizantes permanentes líquidos ou sólidos.Peripheral vascular malformations represent a spectrum of lesions that appear through the lifetime and can be found in the whole body. Such lesions are uncommon and are frequently confounded with infantile hemangioma, a common benign neoplastic lesion.

Maugans, Todd; Sheridan, Rachel M; Adams, Denise; Gupta, Anita

2011-07-01

Lumbosacral cutaneous vascular anomalies associated with neural tube defects are frequently described in the literature as "hemangiomas." The classification system for pediatric vascular anomalies developed by the International Society for the Study of Vascular Anomalies provides a framework to accurately diagnose these lesions. To apply this classification to vascular cutaneous anomalies overlying myelodysplasias. A retrospective analysis of patients with neural tube defects and lumbosacral cutaneous vascular lesions was performed. All eligible patients had detailed histopathologic analysis of skin and spinal cord/placode lesions. Clinical and radiologic features were analyzed. Conventional histology and GLUT-1 immunostaining were performed to differentiate infantile capillary hemangiomas from capillary vascular malformations. Ten cases with cutaneous lesions associated with neural tube defects were reviewed. Five lesions were diagnosed as infantile capillary hemangiomas based upon histology and positive GLUT-1 endothelial reactivity. These lesions had a strong association with dermal sinus tracts. No reoperations were required for residual intraspinal vascular lesions, and overlying cutaneous vascular anomalies involuted with time. The remaining 5 lesions were diagnosed as capillary malformations. These occurred with both open and closed neural tube defects, did not involute, and demonstrated enlargement and darkening due to vascular congestion. The International Society for the Study of Vascular Anomalies scheme should be used to describe the cutaneous vascular lesions associated with neural tube defects: infantile capillary hemangiomas and capillary malformations. We advocate that these lesions be described as "vascular anomalies" or "stains" pending accurate diagnosis by clinical, histological, and immunohistochemical evaluations.

CT morphology of benign median nerve tumors

Computed tomography (CT) was performed in 3 patients with benign tumors of the median nerve, histologically confirmed as neurilemmoma, fibrolipoma and hemangioma. The neurilemmoma showed a ring-shaped contrast enhancement. The fibrolipoma presented with areas of solid soft tissue and areas of fat. The hemangioma was a solid tumor with a lacunar, vascular contrast enhancement. According to our experience and to the previous literature CT gives useful information regarding the anatomic location, size, and relationship of peripheral nerve sheath tumors to surrounding structures, and may help to differentiate between various tumor types.

Computed tomography (CT) was performed in 3 patients with benign tumors of the median nerve, histologically confirmed as neurilemmoma, fibrolipoma and hemangioma. The neurilemmoma showed a ring-shaped contrast enhancement. The fibrolipoma presented with areas of solid soft tissue and areas of fat. The hemangioma was a solid tumor with a lacunar, vascular contrast enhancement. According to our experience and to the previous literature CT gives useful information regarding the anatomic location, size, and relationship of peripheral nerve sheath tumors to surrounding structures, and may help to differentiate between various tumor types.

Full Text Available INTRODUÇÃO: Os tumores hepáticos benignos ocorrem em 9% da população. A grande maioria dessas neoplasias é diagnosticada em pacientes assintomáticos durante a realização de exames de imagem de rotina. OBJETIVO: Apresentar os principais aspectos das indicações e tratamento dos tumores hepáticos benignos. MÉTODOS: Foi realizada revisão de literatura baseada em pesquisa no PubMed, Bireme e Scielo cruzando os descritores neoplasia hepática, hemangioma, adenoma e hiperplasia nodular focal. Foram selecionados, estudos de técnicas cirúrgicas e acrescentada a experiência dos autores. O hemangioma é o tumor hepático mais comum, sendo identificado entre 5% e 7% das necropsias. É mais comum nas mulheres entre as 3ª e 5ª décadas da vida e pode aumentar de tamanho na gravidez e com a administração de estrogênios. Apesar de não estabelecida, a sua causa está relacionada com os hormônios sexuais. As complicações incluem inflamação, coagulopatia, sangramento e compressão de estruturas vizinhas. Rotura espontânea é excepcional, com somente 35 casos descritos na literatura internacional. O adenoma e a hiperplasia nodular focal predominam no sexo feminino e na faixa etária de 20 a 40 anos. Enquanto o primeiro requer ressecção hepática pelo risco de sangramento e malignização, o segundo deve ter conduta expectante. CONCLUSÕES: Os tumores hepáticos benignos mais comuns são em ordem decrescente de frequência o hemangioma, hiperplasia nodular focal e o adenoma. A diferenciação entre tumores benignos e malignos é geralmente realizada com segurança com base nos dados clínicos e nos exames de imagem. O hemangioma e a hiperplasia nodular focal geralmente tem conduta expectante, enquanto que o adenoma requer ressecção pelo risco de hemorragia e de transformação em carcinoma.BACKGROUND: Benign hepatic tumors occur in 9% of the population. The majority is diagnosed in asymptomatic patients during routine imaging exams

Radiation-induced internal carotid artery occlusion has not been well recognized previously as a cause of childhood cerebrovascular disease. A child who had received radiation as a neonate for a hemangioma involving the left orbit at the age of 6 years experienced a recurrent right-sided paresis, vascular headaches, and speech difficulties. Angiography showed a hypoplastic left carotid artery with occlusion of both the anterior and middle cerebral arteries. Collateral vessels bypassed the occluded-stenotic segments. Review of the literature showed two additional cases of large vessel occlusion in childhood associated with anastomatic telangiectatic vessel development following early radiation therapy of facial hemangioma

Full Text Available PHACE syndrome was first described by Dr. Ilonia Frieden and colleagues in 1996. It is an under-recognized rather than a very rare condition among patients with large facial hemangiomas. It is challenging as it has significant neurological, vascular and airway implications. Vascular malformations compromising cerebral blood flow predispose the patient to strokes and seizures. Subglottic hemangiomas, if present, could bleed during intubation. Meticulous neurological monitoring is mandatory in those undergoing repair of the great vessels. We describe the perioperative management of a child with PHACE syndrome subjected to dental treatment under general anesthesia.

PHACES syndrome associates a segmental facial hemangioma with cerebral malformations, aortic branches/cranial arteries anomalies, cardiac defects, eye anomalies or ventral wall defects. The aim of this study is to analyze our experience with this syndrome. Retrospective study of the cases seen at our unit in the last year. We treat 4 cases; 3 girls and 1 child. Besides the segmental hemangioma they presented: 3 vascular cerebral malformations; 2 structural cardiopathies; 2 cerebral malformations, 1 microftalmia. We did not find ventral wall defects. A case received treatment with two cycles of metilprednisolone i.v. and oral prednisone, with favourable course; two cases received initial treatment with oral prednisone continued of oral propanolol in rising pattern up to 2 mg/kg/day, Obtaining both the detention of the tumour growth and regression of the lesion, with very good tolerance. A 7-year-old patient has been treated with colouring pulse laser for her residual lesions. When we see a segmental facial hemangioma we must perform a wide diagnostic study in order to discard a PHACES syndrome. Multidisciplinar approach to the patient by a wide expert's group gets an earlier diagnose and improves the outcome. Propranolol is a promising therapeutic alternative.

To analyze the contrast-enhancement patterns obtained at pulse-inversion harmonic imaging (PIHI) of focal hepatic lesions, and to thus determine tumor vascularity and the acoustic emission effect. We reviewed pulse-inversion images in 90 consecutive patients with focal hepatic lesions, namely hepatocellular carcinoma (HHC) (n=43), metastases (n=30), and hemangioma (n=17). Vascular and delayed phase images were obtained immediately and five minutes following the injection of a microbubble contrast agent. Tumoral vascularity at vascular phase imaging and the acoustic emission effect at delayed phase imaging were each classified as one of four patterns. Vascular phase images depicted internal vessels in 93% of HCCs, marginal vessels in 83% of metastases, and peripheral enhancement in 71% of hemangiomas. Delayed phase images showed inhomogeneous enhancement in 86% of HCCs; hypoechoic, decreased enhancement in 93% of metastases; and hypoechoic and reversed echogenicity in 65% of hemangiomas. Vascular and delayed phase enhancement patterns were associated with a specificity of 91% or greater, and 92% or greater, respectively, and with positive predictive values of 71% or greater, and 85% or greater, respectively. Contrast-enhancement patterns depicting tumoral vascularity and the acoustic emission effect at PIHI can help differentiate focal hepatic lesions.

Purpose: Vertebral hemangiomas (VHs) are the most common benign tumors of the spine that may cause bone resorption. Megavoltage irradiation is usually the treatment of choice for the management of symptomatic VHs. The current study was conducted to estimate the risk for carcinogenesis from radiotherapy of this benign disease on the basis of the calculated radiation doses to healthy organs. Methods: The Monte Carlo N-particle transport code was employed to simulate the irradiation with 6 MV x-rays of a VH presented in the cervical, upper thoracic, lower thoracic, and lumbar spine. The average radiation dose (D{sub av}) received by each critical organ located outside the primarily irradiated area was calculated. Three-dimensional treatment plans were also generated for the VHs occurring at the four different sites of the spinal cord based on patients’ computed tomography data. The organ equivalent dose (OED) to each radiosensitive structure, which was partly encompassed by the applied treatment fields, was calculated with the aid of differential dose–volume histograms. The D{sub av} and the OED values were combined with a linear-no-threshold model and a nonlinear mechanistic model, respectively, to estimate the organ-, age-, and gender-specific lifetime attributable risks (LARs) for cancer development. The estimated risks were compared with the respective nominal lifetime intrinsic risks (LIRs) for the unexposed population. Results: For a standard target dose of 34 Gy, the OED varied from 0.39–5.15 Gy by the organ of interest and the irradiation site. The D{sub av} range for the out-of-field organs was 4.9 × 10{sup −4} to 0.56 Gy. The LAR for the appearance of malignancies in the partially in-field organs after radiotherapy of male and female patients was (0.08%–1.8%) and (0.09%–1.9%), respectively. These risk values were 1.5–15.5 times lower when compared to the respective LIRs. The lifetime probability for out-of-field cancer induction in irradiated

O presente trabalho teve como objetivo descrever as alterações morfológicas de ovários fetais equinos ocorrentes durante o desenvolvimento gestacional. Foram utilizados fetos equinos provenientes de abatedouro. Imediatamente após o abate foi realizada medição da distância cefalococcígea para o cálculo da idade gestacional em dias (dias de gestação - DG e dissecação dos fetos para a retirada e fixação dos ovários. Foram realizadas avaliações macroscópicas e histológicas pelas técnicas de Hematoxilina-eosina e PAS. Foram utilizados 19 fetos com idade de 50-269 dias de gestação, distribuídos em 9 grupos de DG. Na avaliação macroscópica foi observada diferença entre o volume dos ovários de acordo com a idade gestacional, sendo observado maior volume ovariano entre os dias 210 a 269 de desenvolvimento gestacional. Na avaliação histológica foi observado epitélio de revestimento cúbico e distinção entre as camadas cortical e medular nos ovários fetais a partir de 50-89 DG. As principais características identificadas foram à distinção morfológica entre as camadas cortical e medular nos ovários fetais equinos: os cordões ovígeros surgiram no intervalo de 150-179 DG; o córtex iniciada como uma camada delgada e por volta do 210º dia de gestação apresentou espessamento pelo aumento da quantidade de tecido conjuntivo rico em vasos sanguíneos, o qual se manteve até os estágios finais da gestação; a região medular adquiriu uniformidade estrutural por volta do 150º dia, mostrando células similares em tamanho e vasos sanguíneos de calibre maior. A partir desta etapa, as células medulares

Suas aplicações envolvem: diagnóstico de lesões medulares traumáticas; uso intra-operatório em cirurgias do trauma e tumores medulares; uso pré-operatório e evolutivo em pacientes com disrafismos espinhais; diagnóstico pré-natal dos disrafismos; diagnóstico dos disrafismos espinhais ocultos ao nascimento. Pacientes com suspeita de disrafismo espinhal oculto (estigmas cutâneos em linha média ou história familiar de disrafismos representaram a principal indicação do exame que foi realizado em 292 pacientes do Hospital das Clínicas da Universidade Federal de Minas Gerais. Alterações como lipomas do cone medular, medula baixa, filo terminal espesso, cistos da ponta do cone medular e seios dérmicos foram identificados com fidelidade à ultra-sonografia. A interpretação do exame não apresentou dificuldades técnicas. Sua realização é rápida, não é necessária sedação, apresenta baixo custo e idealmente deve ser realizado pelo próprio neurocirurgião devido ao grande número de informações possíveis durante o exame. O exame entretanto não substitui a ressonância magnética mas pode ser um bom método de triagem para os pacientes.Ultrasonography for diagnosis of spinal cord diseases has been used since the eighties. There are different fields for its use: traumatic spine lesions, intra-operative use in trauma and spine tumors surgery, pre-operative and follow up study for spinal dysraphism, occult spinal dysraphism of the newborn. Patients with suspected occult spinal dysraphism are the most important indication for the method. Utrasonography was performed in 292 patients of Hospital das Clínicas, Universidade Federal de Minas Gerais. Lesions such as conus medullaris lipomas, low level of conus medullaris, filum terminale tethering, cauda equina cysts and dermal sinuses can be well demonstrated. There

Full Text Available Os Antiinflamatórios Não Esteróides (AINEs inibem a síntese de prostaglandinas, com subseqüente diminuição da secreção de muco e bicarbonato pelo epitélio gástrico, redução da hidrofobicidade da camada epitelial, comprometimento da reposição celular, redução do fluxo sanguíneo e aumento da aderência de neutrófilos. Ao longo dos anos, notou-se que as lesões gástricas provocadas pelo uso de AINEs se localizam com maior freqüência nas regiões do antro pilórico e curvatura menor do estômago. A maior susceptibilidade destas regiões pode ser explicada por sua anatomia microvascular, a qual apresenta capilares estreitos, tortuosos e com menor diâmetro que em outras regiões do estômago; estes são mais separados entre si e há menos anastomoses entre os capilares ascendentes, tornando-os mais predispostos à trombose e conseqüente lesão gástrica.

Full Text Available Longos períodos de imobilização conduzem à perda óssea e de propriedades do osso, e sua recuperação depende de vários fatores; além disso, a imobilização pode causar ulcerações no tecido cartilaginoso articular devido a alterações como perda de proteoglicanas, de massa e volume totais da cartilagem. O objetivo deste estudo foi verificar alterações histológicas, do tecido ósseo periarticular e da cartilagem articular, provocadas pela imobilização e remobilização de membros posteriores de ratos Wistar. Foram utilizados 12 ratos Wistar, divididos em dois grupos: GI - (n = 6: 15 dias com o membro posterior esquerdo imobilizado em plantiflexão, sendo o membro direito o controle; GR - (n = 6: período de 15 dias de remobilização livre na gaiola, associado a três séries diárias de alongamento do músculo sóleo esquerdo por 30 segundos. Foram avaliados no tecido ósseo as medidas de espessura do osso cortical, diâmetro do canal medular e número de osteócitos; no tecido cartilaginoso, foram mensurados a espessura média da cartilagem e o número de condrócitos. Como resultado, observou-se que para GI não houve alterações significativas na espessura do osso (p = 0,1156 nem no diâmetro do canal medular (p = 0,5698, mas diminuição significativa dos osteócitos em relação ao contralateral (p = 0,0005; em GR também houve decréscimo no número de osteócitos (p = 0,0001, mas as diferenças na espessura (p = 0,1343 e diâmetro do canal medular (p = 0,6456 mantiveram-se não significantes.

Liver own tumors were classified by histological criteria considering the tissue origin. hemangioma and hemangioendothelioma are of mesenchymal origin, the focal nodular hyperplasia (FNH), the hepato-blastoma, hepatocellular adenoma (HCA) or carcinoma (HCC), intrahepatic bile duct cystadenoma or carcinoma are epithelial tumors. Only the hemangioma and the FNH have an unhesitating prognosis. All the other tumors should be diagnosed definitively by histological examination. This means, the tumor has to be resected if possible. To answer the question of resectability radionuclide procedures contribute little. US, transmission tomography, magnetic resonance imaging and angiography are necessary in this case. This chapter deals with findings and problems involved with the use of radionuclide methods.

Maffucci syndrome is a nonhereditary disorder caused by somatic mosaic isocitrate dehydrogenase 1 or 2 (IDH1 or IDH2) mutations and is characterized by multiple enchondromas along with hemangiomas. Malignant transformation of enchondromas to chondrosarcomas and secondary neoplasms, such as brain tumors or acute myeloid leukemia, are serious complications. A 15-year-old female with Maffucci syndrome developed B-cell precursor acute lymphoblastic leukemia (BCP-ALL). A somatic mutation in IDH1 was detected in hemangioma and leukemic cells. KRAS mutation and deletion of IKZF1 were detected in leukemic cells. Patients with Maffucci syndrome may, therefore, be at risk of BCP-ALL associated with secondary genetic events that affect lymphocyte differentiation. © 2017 Wiley Periodicals, Inc.

INFANTILE HAEMANGIOMA

Maria Armanda Passas

2016-06-01

Full Text Available Infantile hemangiomas are the most common softtissue tumors of infancy, occurring in approximately 3 to 10 percent of one-year-old children, with predominance in females. Despite the frequency of these tumors, their pathogenesis is not completely understood, and the best approach to their management remains controversial. They have a well-described natural history of rapid growth during early infancy followed by gradual involution, often leading to complete regression. Because of their spontaneous involution, most infantile hemangiomas do not require therapeutic intervention. However, in 10 to 15 % of cases, treatment is necessary because of local complications, life or physiological functioning is threatened or the long-term esthetic risk is too high.

Full Text Available PURPOSE: The pancreatic capillary blood flow (PCBF was studied to determine its alterations during caerulein-induced pancreatitis in rats. METHODS: Twenty rats were divided in groups: control and caerulein. A laser-Doppler flowmeter to measure PCBF continuously was used. Blood pressure (BP and heart rate (HR were monitored. Serum biochemistry analyses were determined. Histopathological study was performed. RESULTS: The PCBF measured a mean of 109.08 ± 14.54% and 68.24 ± 10.47% in control group and caerulein group, respectively. Caerulein group had a mean decrease of 31.75 ± 16.79%. The serum amylase was 1323.70 ± 239.10U.I-1 and 2184.60 ± 700.46U.I-1 in control and caerulein groups, respectively. There was a significant difference in the PCBF (pOBJETIVO: O fluxo capilar pancreático (FCP foi estudado para determinar suas alterações durante a pancreatite aguda induzida por ceruleína, em ratos. MÉTODOS: Vinte ratos foram divididos em grupo controle e grupo ceruleína. Um laser-Doppler fluxímetro foi empregado para determinar, continuamente, o FCP durante 120 minutos. A pressão arterial média (PAM e a freqüência cardíaca (FC foram determinadas, durante o experimento. Análise bioquímica sérica e estudo histopatológico, por microscopia ótica, do tecido pancreático foram realizados, ao final do experimento. RESULTADOS: O FCP foi em média 109,08 ± 2,17% e 68,24 ± 16,79% nos grupos controle e ceruleína , respectivamente. No grupo ceruleína, houve uma diminuição média de 31,75 ± 16,79%. Os níveis de amilase sérica foram de 1323,70 ± 239,10U.I-1 e 2184,60 ± 700,46U.I-1 nos grupos controle e ceruleína, respectivamente. Houve diferença significante (p<0,05 no FCP e na amilasemia, quando comparado o grupo controle com o grupo ceruleína. Embora micro e macrovacuolização estivessem presentes no grupo ceruleína, não houve diferença histológica entre os grupos. CONCLUSÃO: A diminuição do FCP parece um evento precoce
