    Full Text Available El carcinoma papilar, variante esclerosante difusa, corresponde al 2% de todos los carcinomas papilares de la tiroides. Se caracteriza por comprometer de manera difusa y bilateral a la glándula tiroides. Clínicamente se manifiesta con metástasis ganglionares y pulmonares, afectando predominantemente a mujeres jóvenes. Se describe un caso de taponamiento cardíaco como presentación inicial de un carcinoma papilar de tiroides variante esclerosante difusa. Una mujer de 32 años concurrió al servicio de emergencias médicas refiriendo epigastralgia y tos seca. Durante el examen físico se constató hipotensión arterial, taquicardia y ruidos cardíacos disminuidos. Se realizó un ecocardiograma, observándose derrame pericárdico. Por medio de una pericardiocentesis se obtuvo líquido pericárdico, cuyo análisis mostró células neoplásicas. Durante la evolución la paciente presentó recurrencia del derrame pericárdico por lo que se realizó una ventana pleuropericárdica, detectándose durante la cirugía una lesión nodular subpleural, la cual fue biopsiada e informada posteriormente como una metástasis de carcinoma papilar vinculable a origen tiroideo. Se realizó una tiroidectomía total con linfadenectomía cervical bilateral. El diagnóstico final fue carcinoma papilar, variante esclerosante difusa. Esta variante infiltra el tejido conectivo de los espacios interfoliculares, simulando una tiroiditis y se caracteriza por una permeación vascular temprana. En oposición a la variante clásica, la esclerosante difusa presenta mayor agresividad y mayor tasa de recurrencia. El carcinoma papilar de tiroides debe tenerse presente como diagnóstico diferencial en nuestro medio, en todas aquellas lesiones neoplásicas papilares metastásicas, más aún si se trata de mujeres jóvenes.

    Full Text Available INTRODUCTION: Renal hemangioma is a relatively rare benign tumor, seldom diagnosed as a cause of hematuria. CASE REPORT: A female 40-year old patient presented with continuous gross hematuria, anemia and episodic right lumbar pain, with onset about 3 months previously. The patient underwent multiple blood transfusions during her hospital stay and extensive imaging propedeutics was performed. Semi-rigid ureterorenoscopy evidenced a bleeding focus in the upper calix of the right kidney, with endoscopic treatment being unfeasible. The patient underwent right upper pole nephrectomy and presented a favorable outcome. Histopathological analysis of the surgical specimen showed that it was a renal hemangioma. COMMENTS: Imaging methods usually employed for diagnostic investigation of hematuria do not have good sensitivity for renal hemangioma. However, they are important to exclude the most frequent differential diagnoses. The ureterorenoscopy is the diagnostic method of choice and endoscopic treatment can be feasible when the lesion is accessible and electrocautery or laser are available. We emphasize the open surgical treatment as a therapeutic option upon failure of less invasive methods.

    Full Text Available O hemangioma colorretal (HCR é uma lesão vascular benigna rara, com manifestação clínica geralmente entre 5 e 25 anos de idade. Faz parte do diagnóstico diferencial das causas de hemorragia digestiva baixa, sendo confundido, na maioria das vezes, com entidades mais comuns, como hemorróidas e doenças inflamatórias intestinais. O retardo do diagnóstico ocorre freqüentemente devido ao desconhecimento da doença, com taxas de mortalidade alcançando 40 a 50% na presença de sangramento importante. O caso relatado é de uma paciente de 17 anos de idade, admitida no Serviço de Colo-proctologia do Hospital Universitário - HUUFMA, em setembro de 2005, com anemia e sangramento retal, desde a infância, de forma intermitente e não dolorosa. Apresentado sua história clínica e propedêutica diagnóstica, realizada por meio de exames laboratoriais, endoscopia digestiva alta, colonoscopia e arteriografia de mesentéricas e ilíacas internas. O tratamento cirúrgico realizado foi retossigmoidectomia convencional com anastomose colorretal baixa, com boa evolução pós-operatória, tendo o exame histopatológico da peça cirúrgica ressecada, confirmado o diagnostico.The colon and rectum hemangioma is a rare benign vascular lesion, with clinical features usually between 5 and 25 years of age. It is included in the differential diagnose of the lower digestive bleeding causes, and has been frequently misdiagnosed with other more common entities, like hemorrhoids and bowel inflammatory disease. The late diagnose occurs usually because of the rarity of the disease, with mortality rates reaching 40 to 50% in presence of severe bleeding. We report a case of a 17 years old girl who was admitted at the Coloproctology Service of the Academic Hospital - HUUFMA, in September 2005, with anemia and intermittent rectal bleeding since childhood.

    Full Text Available Nasal lobular capillary hemangioma is a rare benign tumor of the paranasal sinuses. This lesion is believed to grow rapidly in size over time. The exact etiopathogenesis is still a dilemma. We discuss a case of nasal lobular capillary hemangioma presenting with a history of epistaxis. Contrast enhanced computed tomography of paranasal sinuses revealed an intensely enhancing soft-tissue mass in the left nasal cavity and left middle and inferior meati with no obvious bony remodeling or destruction. We present imaging and pathologic features of nasal lobular capillary hemangioma and differentiate it from other entities like nasal angiofibroma.

    Full Text Available Neste trabalho estudamos as alterações histopatológicas encontradas no sistema nervoso central de dois pacientes com "panencefalite subaguda esclerosante" comparando-as com as modificações estruturais determinadas no sistema nervoso central de sete macacos rhesus nos quais este material foi inoculado. Os animais apresentaram sinais de comprometimento neurológico, traduzido por caquexia e paralisia do trem posterior, após um longo período de incubação, em torno de 18 meses. Dois animais morreram antes de qualquer manifestação neurológica, de infecção pulmonar intercorrente acidental. Nas passagens sucessivas houve um encurtamento do periódo de incubação para cerca de 40 dias. As alterações histopatológicas encontradas, consistiram, nos casos humanos, em leptomeningite focal, focos de neuronofagia, granulomas corticais e nos núcleos basais, grande perda da população neuronal com ocasional estado esponjoso do córtice cerebral, infiltrados perivasculares, e gliose da substância branca, sem perda de mielina. No material experimental foram observadas estas mesmas modificações, se bem que de caráter muito menos intenso. Tanto no material humano como no experimental a mielina estava praticamente normal. Sugere-se que o quadro anátomo-clínico chamado "panencefalite subaguda esclerosante (SSPE possa ser determinado, não apenas pelo vírus do sarampo, mas também por outros vírus, especialmente os do grupo papova, já encontrado por outros autores, em casos de "panencefalite subaguda esclerosante".The authors describes the histopathological changes found in the central nervous system of two patients with subacute sclerosing panencephalitis.

    Full Text Available Hemangiomas are benign lesions that occur in any part of the body in newborns or in young patients, they are typically capillary or cavernous. Cavernous hemangioma of the penis is extremely rare; and its etiology is not completely understood. Treatment options (surgical excision, laser therapy or sclerotherapy… are controversial and are required if pain, cosmetic defect and/or bleeding during intercourse.                                                  We report a case of a 26 years old man presented with a five years history of a painless lesion on his penis. 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.

    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.)

    Full Text Available O hemangioma é o tumor benigno mais freqüente da infância. O hemangioma capilar geralmente apresenta-se como uma mancha ou tumoração violácea bem delimitada. O diagnóstico destas lesões é clínico. O hemangioma gigante é rara e extensa variação do hemangioma capilar, que geralmente ocorre em recém-nascidos e lactentes. Várias são as modalidades terapêuticas, como a injeção intralesional de corticóide, laserterapia, injeção intralesional de soluções esclerosantes, corticoterapia sistêmica, cirurgia, radioterapia e embolização. Novas modalidades terapêuticas têm sido desenvolvidas, com o objetivo de se obter melhores resultados e possibilitar o tratamento de lesões de difícil acesso cirúrgico e refratárias às modalidades terapêuticas utilizadas rotineiramente. Os melhores resultados tem sido obtidos com o interferon alfa. Este é um caso de uma paciente com três meses de idade, que apresentava desde o nascimento, tumoração arroxeada e amolecida em pálpebra superior do olho direito, lesões cutâneas planas e arroxeadas em região temporal e parietal direita. Realizada tomografia computadorizada de crânio evidenciando processo expansivo orbitário vascularizado com extensão para fossa média, seio cavernoso e fossa posterior. O tratamento inicial foi a corticoterapia oral durante quarenta dias, com redução progressiva por quatro semanas. Com o quadro praticamente inalterado, foi iniciado o tratamento com interferon alfa, na dose de 3.000.000 U/m², subcutâneo, três vezes por semana. Após 9 meses de tratamento, observa-se apenas uma pequena lesão orbitária residual. Neste caso, o interferon alfa apresentou-se como boa opção no tratamento do hemangioma gigante craniofacial.Hemangiomas are the most commom benign tumors of infancy.

    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.

    Full Text Available As formas de eosinofilia pulmonar constituem um grupo heterogêneo definido pela presença de um ou dois critérios: infiltrado pulmonar com eosinofilia sanguínea e/ou eosinofilia tissular caracterizada por eosinófilos demonstrados na biópsia pulmonar ou no lavado broncoalveolar. Embora o infiltrado inflamatório seja composto de macrófagos, linfócitos, neutrófilos e eosinófilos, a presença de eosinofilia é um marcador importante para o diagnóstico e tratamento. A apresentação clínica e radiológica pode revelar eosinofilia pulmonar simples, pneumonia eosinofílica crônica, pneumonia eosinofílica aguda, aspergilose broncopulmonar alérgica e eosinofilia pulmonar associada à doença sistêmica, como na síndrome de Churg-Strauss e na síndrome hipereosinofílica. A asma está frequentemente associada, podendo ser um pré-requisito, como na aspergilose broncopulmonar alérgica e na síndrome de Churg-Strauss. Nas doenças com acometimento sistêmico, a pele, o coração e o sistema nervoso são os órgãos mais comprometidos. A apresentação radiológica pode ser considerada como típica, ou pelo menos sugestiva, para três formas de eosinofilia pulmonar: pneumonia eosinofílica crônica, aspergilose broncopulmonar alérgica e pneumonia eosinofílica aguda. A etiologia da eosinofilia pulmonar pode ser de causa primária (idiopática ou secundária, compreendendo causas conhecidas, como drogas, parasitas, infecções por fungos e micobactérias, irradiação e toxinas. A eosinofilia pulmonar pode também estar associada a doenças pulmonares difusas, doenças do tecido conectivo e neoplasias.Pulmonary eosinophilia comprises a heterogeneous group of diseases defined by eosinophilia in pulmonary infiltrates (bronchoalveolar lavage fluid or in tissue (lung biopsy specimens.

Afecta solo a la mandíbula y es generalmente unilateral, compromete hueso basal y alveolar, y se localiza al nivel de cuerpo, ángulo, rama e incluso cóndilo. La causa es aún controversial, ya que algunos le atribuyen un origen infeccioso, mientras otros lo consideran una condición no infecciosa, como producto de sobrecargas o asociado con síndrome SAPHO (sinovitis, acné, pustulosis, hiperostosis y osteítis, pero la literatura no es concluyente. Con respecto al tratamiento, al igual que su causa, no está totalmente esclarecido y se describen a lo largo del tiempo distintas alternativas, que van desde lo conservador a lo más radical. Se presenta el seguimiento y tratamiento durante 7 meses de una paciente afectada por osteomielitis esclerosante difusa con 18 años de evolución aproximadamente, que ha sido refractaria a las alternativas terapéuticas convencionales.Diffuse sclerosing osteomyelitis is considered a chronic primary osteomyelitis consisting in an inflammatory, painful and prolonged process. It only affects the mandible and it is generally unilateral. It involves the basal and alveolar bone and it is located at the level of body, angle, branch and even condyle. The cause is more controversial, since some attribute an infectious origin to it, whereas others consider it as a non-infectious condition resulting from the overloads or associated with SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis and osteitis, but literature is not concluding.

    Full Text Available RESUMO Um cão SRD, com cinco anos e histórico de ascite de evolução lenta com estruturas palpáveis foi submetido a exames clínicos, os quais foram inconclusivos. A laparotomia exploratória revelou que a cavidade abdominal estava repleta de líquido serossanguinolento e de múltiplos nódulos de diferentes tamanhos, com superfície irregular, aderidos aos peritônios visceral e parietal, sugestivos de neoplasia maligna. A eutanásia, seguida da necropsia para a coleta de amostras para o diagnóstico histopatológico, foi indicada. O exame anatomopatológico revelou nódulos sésseis e resistentes ao corte, constituídos de tecido conjuntivo fibroso e trabéculas ósseas em arranjo de osso esponjoso e osteoclastos em atividade. O diagnóstico definitivo foi peritonite encapsulante esclerosante.

    Nasopharyngeal masses are usually malignant, and benign nasopharyngeal tumors such as hemangioma are unusual. In adults, hemangiomas do not involute spontaneously, but progress. Imaging modalities are useful to rule out other malignancies and vascular lesions and to evaluate the lesion. Most hemangiomas require no therapy, but certain factors such as age of the patient and location and size of the lesion may make treatment necessary. We report a case of an unusual nasopharyngeal hemangioma treated with endoscopic excision in an adult who complained of hearing loss.

    Airway hemangiomas can be difficult to manage and cause anxiety in both the parents and the treating physician. Propranolol, a nonselective beta-blocker, has recently been used for treating proliferating infantile hemangiomas. We report successful management of a proliferating, large, mixed infantile hemangioma with subglottic extension in an Indian infant using oral propranolol in a dose of 2mg/kg/day without any side effects. Induction of early involution and freedom from the side effects of steroid therapy seem encouraging for using propranolol as a first line treatment modality in the management of troublesome hemangiomas. © 2013 The International Society of Dermatology.

    Full Text Available OBJETIVO: Descrever oito casos de inflamação esclerosante idiopática da órbita, incluindo a análise clínica e histopatológica. MÉTODOS: Estudo retrospectivo através do livro de registros do Laboratório de Patologia Ocular (LPO do Hospital Universitário Professor Edgard Santos, Universidade Federal da Bahia, no período de 1974 a 2010. Além de revisão de lâminas de todos os casos e das imagens clínicas e de exames complementares recuperadas dos arquivos pessoais dos autores. RESULTADOS: Dentre o total de espécimes submetidos ao LPO (7546 apenas 8 casos receberam diagnóstico final de inflamação esclerosante idiopática da órbita. Em todos os casos houve piora ou deterioração da acuidade visual à despeito do tratamento, com exceção de um, que permaneceu com a mesma visão (percepção luminosa. Em nosso estudo, observamos envolvimento orbitário predominantemente apical. Todos os nossos pacientes foram submetidos à biópsia incisional com finalidade diagnóstica. Também submeteram-se à corticoterapia e em um caso foi associada à radioterapia anti-inflamatória; em dois destes casos, foi utilizado também ciclofosfamida. Dois pacientes com acuidade final sem percepção luminosa tiveram que ser submetidos à exenteração parcial da órbita para tratamento de dor incontrolável. CONCLUSÃO: A inflamação esclerosante orbitária idiopática permanece como uma doença pouco conhecida, de péssimo prognóstico visual.

    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.

    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.

    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.)

O processo desenvolveu-se de maneira gradativa durante alguns anos. Ao dar-se o óbito, 6 anos após as manifestações clínicas iniciais, cosntatou-se, ao estudo anátomo-patológico, um processo encefalítico em plena evolução, com microgranulomas, infiltrados inflamatórios perivasculares, focos de neuronofagia e inclusões acidófilas intranucleares em células oligodêndricas. Os astrócitos da substância branca cerebral, onde havia desmielinização maciça, exibiam uma reação hiperplástica anormal, com atipias nucleares muito intesnsas. Este caso apresentou, portanto, as características histopatológicas de uma virose crônica, com anos de evolução. Além disso, tendo-se em vista a possibilidade da existência de vírus do grupo papova em casos de SSPE, fato já demonstrado, é possível que no presente caso existissem vírus desde grupo participando do processo, dadas as intensas atipias apresentadas pelos astrócitos nas áreas desmielinizadas.This article relates a case of subacute sclerosing panencephalitis (SSPE with special characteristics. The patient was a young male, eight years old. The disease progressed slowly over a period of several years terminating in death six years ofter the initial symptoms. Histopathologic examination revealed an encepahilitic process in evolution, with microgranulomes, perivascular inflammatory infiltrates, areas of neuronophagia, and intranuclear acidophilic inclusions in oligodendroglial cells. The cerebral white matter presented massive areas of demyelination, with astroglial cells undergoing an abnormal hyperplastic reaction with great nuclear atypias. This case, therefore, presented the histopathological picture of a chronic viral infection of several years' duration. Since it has been

    Full Text Available Material proveniente do cérebro de um paciente com "panencefalite subaguda esclerosante" foi inoculado, por via intracerebral, em dois Macacus rhesus. Os animais permaneceram assintomáticos, aparentemente bem, por mais de um ano. Entretanto, 21 e 22 meses após as inoculações começaram a apresentar sinais de comprometimento neurológico, traduzido por paralisia dos membros posteriores, com apatia e caquexia progressivas. Os animais foram sacrificados. O exame histopatológico do sistema nervoso central mostrou gliose marginal e gliose da substância branca, com os neurônios exibindo sinais de "lesão celular crônica". Foram vistos discretos manguitos inflamatórios perivasculares. Em um animal foi encontrada inclusão acidófila intra- nuclear. Havia também proliferação da glia satélite perineuronal, com satelitose, notadamente no tronco cerebral. No exame das vísceras foi encontrado discreto processo de miocardite crônica. Foram retirados fragmentos dos encéfalos destes animais e inoculados em 4 outros, também por via intracerebral. Estes animais de 2.ª passagem após 2 meses de inoculação, em média, apresentaram sinais de comprometimento do sistema nervoso central semelhante ao dos animais doadores, de 1ª passagem. Houve, portanto, um encurtamento do período de inoculação da moléstia. Estes animais também foram sacrificados, sendo encontradas gliose marginal, gliose da substância branca, "lesão celular crônica" neuronal e proliferação da glia satélite, notadamente no tronco cerebral; vasos sangüíneos congestos; espongiose cortical. Os animais testemunhas, do mesmo lote, permaneceram normais. Acreditamos que as lesões observadas nos animais de 1.ª passagem, e que se repetiram com maior intensidade e com menor tempo de incubação nos de 2.ª passagem somente podem ser explicadas admitindo-se a existência de um agente virai que, pela natureza do quadro histopatológico (gliose, "lesão celular cr

    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.)

    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.

    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.

    Full Text Available O hemangioma rubi (HR é dermatose de origem vascular extremamente freqüente, acometendo mais de 75% da população acima de 70 anos de idade. Em geral compõe-se de lesões múltiplas,localizadas predominantemente no alto do tronco e braços. Clinicamente é caracterizado por lesões que variam desde máculas puntiformes até lesões papulosas com cinco milímetros de diâmetro. As mais novas são vermelhas, em tons vivos, e as mais antigas podem ser azuladas. O HR é de etiologia desconhecida. Histologicamente chama atenção uma neoformação de vasos capilares, que se tornam dilatados e com fenestrações em suas paredes. A membrana basal está muito espessada e existe abundante estroma de colágeno entre os vasos. O presente trabalho demonstra a alta incidência do HR no couro cabeludo Em amostra de 171 pacientes, sendo 85 homens e 86 mulheres, o autor observou que 123 deles (72% tinham HR no couro cabeludo, localização em que o HR nunca foi descrito na literatura.Cherry hemangioma (CH is an extremely frequent dermatosis with vascular origin involving more than 75% of the population over 70 years of age. Normally they are multiplex spots and focus predominantly on the upper trunk and arms. Clinically they are characterized by pinpoint maculae and papules with up to 5 millimeters in diameter. The most recent lesions can be a strong red color while the older ones are bluish. The etiology of CH is still unknown. From the histologic standpoint, the neoformation of the capillary tube draws attention: they are very dilated and with fenestration along the wall. The basement membranes are thickened and there is abundant collagen stroma between the veins. This work demonstrates the high frequency of CH in the scalp. In a sample of 171 patients (85 men and 86 women the author noted that 123 (72% had CH in the scalp. However, according to the literature, CH in the scalp has never been described.

    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.

    To determine the optimal pulse sequence for detection and differential diagnosis of small hepatocellular carcinomas and cavernous hemangiomas less than 5 cm in diameter, the authors have analyzed spin-echo (SE) images of 15 small hepatocellular carcinomas and 31 small cavernous hemangiomas obtained at 2.0 T. Pulse sequences used included repetition times (TRs) of 500 and 2,000 msec and echo times (TEs) of 30,60,90,120,150, and 180 msec. Mean tumor-liver contrast-to-noise ratios on the SE 2,000/60 (TR msec/TE msec) sequence were 23.90 ± 16.33 and 62.10 ± 25.94 for small hepatocellular carcinomas and hemangiomas, respectively, and were significantly greater than for all other pulse sequences. Mean tumor-liver signal intensity ratios on the SE 2,000/150 sequence were 2.34 ± 1.72 and 6.04 ± 2.72 for small hepatocellular carcinomas and hemangiomas, respectively, and were significantly greater than for all other pulse sequences in hemangiomas

    Full Text Available Hemangioma is one of the most common benign tumorsin the head and neck region. Laryngeal hemangiomasare benign vascular tumors of unknown etiology thatarise from subglottic region with stridor in infants. Thistype also known as congenital laryngeal hemangioma, isthe more common. Congenital hemangiomas occur usuallyin subglottic region and more frequent in girls. Laryngealhemangioma in adults is a very rare conditionand main symptom is hoarseness and breathing difficulties.Adult hemangiomas can be seen in different locationssuch as the epiglottis, aryepiglottic folds, arytenoidsand false and true vocal cords. They are more oftenof cavernous form and cause hoarseness. In this reportwe present an adult patient with hemangioma ofthe left vocal fold and review the literature. Diagnosticinvestigation revealed a pink-purple mass which was extendedfrom the anterior comissure to the posterior partof true vocal cord and false vocal cord, filling the ventriculeand extending to supraglottic region. Directlaryngoscopy was performed, but the lesion was not excisedbecause of its widespread extension in the larynx. JClin Exp Invest 2010; 2(1: 91-94

    Rapidly involuting congenital hemangioma (RICH) is a recently recognized entity in which the vascular tumor is fully developed at birth and undergoes rapid involution. Angiographic findings in two infants with congenital hemangioma are reported and compared with a more common postnatal infantile hemangioma and a congenital infantile fibrosarcoma. Congenital hemangiomas differed from infantile hemangiomas angiographically by inhomogeneous parenchymal staining, large and irregular feeding arteries in disorganized patterns, arterial aneurysms, direct arteriovenous shunts, and intravascular thrombi. Both infants had clinical evidence of a high-output cardiac failure and intralesional bleeding. This congenital high-flow vascular tumor is difficult to distinguish angiographically from arteriovenous malformation and congenital infantile fibrosarcoma. (orig.)

    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)

    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)

    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.

    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.

    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...

    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

    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.

    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.

Os achados mais freqüentes na tomografia do tórax foram as massas e os nódulos pulmonares. Outros aspectos observados foram as áreas de escavação, as consolidações, o espessamento do interstício peribroncovascular e o reticulado difuso. Massa pulmonar foi o achado isolado mais comum (64,2%, seguido dos nódulos isolados ou múltiplos (35,7%. Doença pulmonar difusa foi vista em apenas 14,2% dos casos. Os lobos superiores foram os mais comprometidos, sendo a doença mais comum nas regiões anteriores. A tomografia do tórax permitiu avaliar com precisão o grau de comprometimento do parênquima pulmonar.

    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.)

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 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

    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

    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.)

    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.

    A 25-year-old woman presented with a four-year history of progressive right-lower-extremity weakness and atrophy and a left hemisensory deficit was found. Metrizamide-enhanced spinal CT scan showed an intramedullary lesion at the level of T1-T2; this had expanded the cord in fusiform fashion but showed no evidence of a cystic component. Surgical resection was performed and the pathological diagnosis was cavernous hemangioma. Two and one-half years later, her left hemisensory deficit was worsening and a spinal MRI showed high signal intensity mass in the region of the previous surgery consistent with chronic hematoma which was re-evacuated with some improvement in the patient's neurological condition.

    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.

    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.

    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.

    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

    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.

    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)

    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.

    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.

    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.

    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.

    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.

    2008-02-01

    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.

    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 Resumo: Os autores descrevem o caso de uma mulher de 50 anos, fumadora. Assintomática até Setembro de 2003, altura em que refere o aparecimento de tosse seca, cansaço e perda de peso. Na radiografia do tórax eram evidentes duas massas, uma no lobo superior direito e outra no lobo lingular. A doente foi submetida a biópsia aspirativa transtorácica e a citologia obtida foi compatível com carcinoma de pulmão do tipo pequenas células. No estadiamento da doença foram identificadas lesões hepáticas secundárias, motivo porque a doença foi considerada como disseminada, dada a existência de lesões hepáticas e pulmonares contra-laterais. Foi, nesta fase, iniciada quimioterapia com carboplatinum e etoposídeo. Seis meses mais tarde, a lesão direita inha diminuído, mas a lesão esquerda apresentava aumento das suas dimensões. A biópsia desta lesão mos-trou uma citologia compatível com adenocarcinoma do pulmão, motivo porque inicia novo ciclo de quimioterapia com vinorelbina e gencitabina. Aos quatro ciclos e por não se evidenciar nenhuma resposta ao tratamento, foi realizada radioterapia da lesão esquerda. Durante este período (28 meses mantém-se assintomática, mantendo a sua actividade diária habitual.De acordo com o momento do diagnóstico as neo-plasias do pulmão podem ser consideradas síncronas ou metácronas. Estas últimas são mais frequentes, re-presentando cerca de 50-70% dos casos, sendo o pa-drão histológico mais frequente o adenocarcinoma.No caso apresentado, a situação parecia ser uma doença disseminada, o que afastou a hipótese de tumores síncronos. Apesar de a doença se apresentar num estádio avançado aquando do diagnóstico e do mau prognósti-co associado, a evolução dos dois tipos de tumor não pareceu comprometer a actividade diária da doente.Rev Port Pneumol 2007; XIII (2: 287

    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.

    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.

    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.

    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

    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

    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

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

    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

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. Extensive lesions that affect the visual axis require local and systemic treatments, alone or in combination, in order to reduce the size and impact of lesions on the eyeball, to reduce induced refractive error and

    Highlights: • PEDF was expressed and induced during the involuting phase of IH. • PEDF inhibited the cell growth of the involuting HemECs in an autocrine manner. • PEDF suppression restored the impaired cell growth of the involuting HemECs. - Abstract: Hemangioma is a benign tumor derived from abnormal blood vessel growth. Unlike other vascular tumor counterparts, a hemangioma is known to proliferate during its early stage but it is followed by a stage of involution where regression of the tumor occurs. The critical onset leading to the involution of hemangioma is currently not well understood. This study focused on the molecular identities of the involution of hemangioma. We demonstrated that a soluble factor released from the involuting phase of hemangioma-derived endothelial cells (HemECs) and identified pigment epithelium-derived factor (PEDF) as an anti-angiogenic factor that was associated with the growth inhibition of the involuting HemECs. The growth inhibition of the involuting HemECs was reversed by suppression of PEDF in the involuting HemECs. Furthermore, we found that PEDF was more up-regulated in the involuting phase of hemangioma tissues than in the proliferating or the involuted. Taken together, we propose that PEDF accelerates the involution of hemangioma by growth inhibition of HemECs in an autocrine manner. The regulatory mechanism of PEDF expression could be a potential therapeutic target to treat hemangiomas.

    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.

    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....

    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

    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.

    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.

    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

    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

    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.

    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.

    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.

    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

    2014-01-01

    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 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.

    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.

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.

    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

  1. 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.

    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

Entre las causas más importantes de muerte por tabaquismo están el cáncer pulmonar y la enfermedad pulmonar obstructiva crónica (EPOC. La erradicación del tabaquismo es la mejor estrategia de prevención de estas enfermedades. La segunda estrategia es la detección precoz de ellas. Sin embargo la EPOC está sub diagnosticada en todo el mundo. No está claro si la solución es hacer más espirometrías en población de riesgo. Es posible que otros métodos diagnósticos como la tomografía axial computada de tórax (TAC y la difusión pulmonar, puedan mejorar la capacidad de diagnóstico precoz de esta enfermedad. El cáncer pulmonar es el más mortal de los cánceres. El diagnóstico en etapas tempranas mejora significativamente su pronóstico.

    Full Text Available La presencia de hipertensión pulmonar (HP en el embarazo es poco frecuente y conlleva un alto riesgo para madres e hijos. Existe escasa bibliografía relacionada al diagnóstico de la misma luego del parto. Se describen tres pacientes a quienes se diagnostica HP luego de cursar sus embarazos y partos libres de eventos. A pesar de desconocerse las causas, son varios los mecanismos propuestos, como la hipercoagulabilidad, la hipoxia placentaria o la embolia de líquido amniótico. Resulta difícil definir si la HP diagnosticada en el puerperio, corresponde a una HP en período asintomático que fue desenmascarada por el estrés fisiológico del parto o es una condición de reciente comienzo. A pesar de la falta de datos que avalen la ausencia de HP previa al embarazo en nuestras tres casos, el curso libre de eventos en sus embarazos, sin síntomas y con partos normales, indican que no padecían esta enfermedad hasta el momento del parto, y que la desarrollaron posteriormente. De haberla padecido antes se hubieran presentado síntomas previos al parto o en el puerperio inmediato, ya que las demandas hemodinámicas deterioran gravemente a un ventrículo con poca reserva.

    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

    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.

    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.

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.

La historia de la tuberculosis es un tema apasionante. En pocas enfermedades es posible documentar su estrecha relación con la historia de la propia humanidad como en la que nos ocupa. Existen evidencias paleológicas de tuberculosis vertebral en momias egipcias que datan aproximadamente del año 2400 a.C. La tuberculosis se ha conocido a través de la historia, con los nombres de: tisis, consunción, escrófula, mal de Pott, plaga blanca y mal del rey.1 En el artículo se plantea como conclusión que la tendencia de la tuberculosis en el quinquenio de estudio es estacionaria, pero en los últimos cuatro años tiende al ascenso. En los casos diagnosticados de tuberculosis en este quinquenio más de dos tercios correspondieron al sexo masculino y mayores de 45 años, las ocupaciones que más prevalecieron fueron recluso, desocupado, ama de casa y jubilado. Los factores de riesgo que más se relacionaron fueron el albergamiento prolongado en instituciones cerradas, el alcoholismo, y la edad mayor de 65 años; la forma clínica de mayor incidencia en casi la totalidad de los pacientes fue la pulmonar y, dentro de ella, los casos con baciloscopia positiva.

    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.

    Full Text Available El manejo del paciente con hipertensión pulmonar es complejo y requiere de un equipo interdisciplinario. Es trascendental que los programas de rehabilitación cuenten con neumólogo, fisioterapeutas entrenados, psicólogos, profesionales en trabajo social, nutrición y enfermería. Para el ingreso al programa los pacientes deben contar con manejo farmacológico óptimo y prueba de ejercicio cardiopulmonar integrada o prueba de caminata de seis minutos para determinar la condición basal, las causas de limitación al ejercicio y la intensidad del ejercicio, y prever riesgos. Se indican al menos dos a tres sesiones a la semana supervisadas durante 10 a 12 semanas para lograr mejoría en cuanto a capacidad de ejercicio, calidad de vida y niveles de actividad física. Se puede hacer entrenamiento en ambiente hospitalario, ambulatorio o mixto aunque siempre con comienzo en un ámbito supervisado y con el equipo de monitorización necesario. En cuanto al riesgo, en pacientes con hipertensión pulmonar clase funcional IV, la frecuencia de eventos adversos no fue mayor al compararse con pacientes en clase funcional II y III; los efectos del entrenamiento en estos pacientes son similares a los obtenidos en aquellos con mejor clase funcional con necesidad de reducir la intensidad del ejercicio para que sea tolerado y seguro. Es vital educar tanto al paciente como a su cuidador en cuanto a la enfermedad, y adicionalmente brindar soporte psicosocial y nutricional.

    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.

    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.

    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.

    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)

Se caracterizan por cambios inflamatorios y fibróticos que causan remodelación de las paredes alveolares y de las vías respiratorias distales, y ocasionan un defecto restrictivo funcional y una alteración en el intercambio gaseoso, con hipoxemia progresiva. Son muchas las enfermedades que pueden afectar al intersticio pulmonar y múltiples las formas etiológicas causadas por una variedad de procesos patológicos, que incluyen, factores genéticos, asociación a enfermedades sistémicas, así como a respuestas inflamatorias o fibróticas a diferentes estímulos. Sin embargo, algunas veces su origen es desconocido, y se catalogan entonces como idiopáticas. Los neumólogos pediátricos han tratado de clasificar los casos de las enfermedades pulmonares intersticiales en las diferentes categorías descritas originalmente en adultos, pero, en realidad, existen formas del adulto que no se observan en la infancia, y formas únicas de presentación pediátrica. Se señala la importancia del conocimiento de estas entidades, particularmente las de origen desconocido o idiopáticas.

    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

    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.

    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

    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.

    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.

    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.

    Capillary hemangioma of the adult nasal cavity is rare. We report a case which occurred in the right nasal cavity of a 25-year-old woman, together with the multiphase enhanced CT findings. The patients who had a history of recurrent nasal bleeding, had experienced nasal obstruction and swelling during the two-month period prior to presentation, and one month before presentation, spontaneous vaginal delivery occurred. Physical examination revealed the presence of a well-defined round mass, with redness in the right nasal vertibule. The mass showed rim enhancement at early arterial-phase CT scanning, increased enhancement at the late arterial phase, and moderately homogeneous enhancement at the delayed phase

    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

    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

    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)

    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.

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.

    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.

    Full Text Available La definición universalmente aceptada de hipertensión pulmonar corresponde a todos los pacientes con presión arterial pulmonar media igual o mayor a 25 mm Hg en reposo, medida por cateterismo cardíaco derecho, sin olvidar que la presión promedio normal de la arteria pulmonar es de máximo 20 mm Hg, lo cual obliga a seguir a los pacientes con presión arterial pulmonar media entre 20 y 24 mm Hg. También cabe recordar ser claros al diferenciar entre hipertensión pulmonar e hipertensión arterial pulmonar. La hipertensión pulmonar incluye cinco grupos, entre los cuales la hipertensión arterial pulmonar constituye el grupo 1. El concepto de hipertensión arterial pulmonar inducida por el ejercicio puede definirse como todos los pacientes con presión arterial pulmonar por encima de los 30 mm Hg a un gasto cardíaco menor de 10 l, o una resistencia pulmonar total de más de 3 unidades Wood. La hipertensión pulmonar inducida por el ejercicio es un campo de investigación hasta ahora poco explorado. La clasificación continúa con los cinco grupos, y es dinámica de acuerdo con el progreso en entender la fisiopatología de cada enfermedad.

    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.

    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.

    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.)

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

    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-irradiattion 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. (author)

    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.

    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.

    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

    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)

    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.

    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

    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.

    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.

    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

    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.

    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.

    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.)

    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.

    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.

    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)

    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{sup 3} (range, 6.8–83.2 cm{sup 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.

  7. Urea immunoliposome inhibits human vascular endothelial cell proliferation for hemangioma treatment

    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

    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.

    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.

    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.

    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

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

    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

    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)

    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

    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

    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.

    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.

    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

    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.

    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.

    Full Text Available La fibrosis pulmonar idiopática (FPI es una enfermedad que se caracteriza por presentar un compromiso pulmonar de tipo restrictivo, resultante de una reducción en la complacencia pulmonar secundaria a fibrosis difusa. En el enfisema, la pérdida de elasticidad pulmonar y el colapso de las vías aéreas periféricas generan obstrucción e hiperinflación. El efecto simultáneo que ambas enfermedades producen sobre la fisiología pulmonar no es del todo claro y se han descripto volúmenes pulmonares normales o casi normales. Presentamos 4 pacientes de sexo masculino de 64, 60, 73 y 70 años, con antecedentes de tabaquismo e historia de disnea progresiva, tres de ellos con grave limitación en su calidad de vida al momento de la consulta. En la tomografía de tórax de alta resolución todos los pacientes presentaban signos de enfermedad intersticial pulmonar avanzada, con cambios de tipo fibrótico con predominio basal y subpleural, que coexistían con enfisema centroacinar con predominio en lóbulos superiores. Uno de ellos tuvo confirmación diagnóstica de ambas condicioes por biopsia pulmonar a cielo abierto. En los cuatro pacientes la espirometría y volúmenes pulmonares fueron normales, pero tenían importante compromiso del intercambio gaseoso evaluado mediante el test de caminata de 6 minutos. Tres de los pacientes tenían hipertensión pulmonar grave diagnosticado por ecocardiograma. La presencia de volúmenes pulmonares normales no excluye un diagnóstico de fibrosis pulmonar idiopática en pacientes fumadores si coexisten evidencias tomográficas de enfisema. En estos pacientes el grado de compromiso funcional, determinado por la reducción de los volúmenes pulmonares, no debería ser considerado en la evaluación de la gravedad.Pulmonary function tests in idiopathic pulmonary fibrosis characteristically show a restrictive pattern, resulting from reduction of pulmonary compliance due to diffuse fibrosis.

    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.

    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

    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.

    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

    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.

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

    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.

    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.

    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.

    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 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.

    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.

    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.

    Hemangiomas primários do fígado são neoplasias benignas que podem comprometer a sobrevivência do animal, em virtude da compressão de vasos, ductos e hepatócitos adjacentes, especialmente pela possibilidade de rupturas e morte por hipovolemia. Por serem raros em felinos, objetiva-se relatar o caso de uma gata Persa, com 10 anos de idade, cujos sinais clínicos eram: aumento de volume abdominal, vômitos intermitentes, apatia e anorexia, além de cios irregulares. No exame radiográfico se observou massa tecidual radiopaca no fígado. Na ultra-sonografia hepática, percebiam-se contornos irregulares, parênquima heterogêneo, hiperecogênico, com áreas cavitárias, sugestivo de neoplasia e cistos. No exame macroscópico, visibilizaram-se ascite sanguinolenta, esteatose hepática e massa neoplásica única com 12 cm de comprimento por 8 cm de largura e diversos cistos. Os ovários e rins se apresentavam policísticos e havia hiperplasia endometrial cística. Microscopicamente foram diagnosticadas no fígado formações císticas limitadas por endotélio e delgada cápsula de tecido conjuntivo, esteatose e hepatite periportal mononuclear-linfocitária com proliferação de ductos bilíferos. A massa tumoral originava-se a partir do tecido conjuntivo da cápsula hepática e se caracterizava pela presença de brotos vasculares oriundos de células endoteliais, com dilatação e anastomose de vasos nas áreas mais superficiais. Os achados observados são compatíveis com o diagnóstico de hemangioma hepático primário do tipo capilar-cavernoso. Nos ovários, no útero, nos rins e fígado, constatou-se doença policística.

    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

    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.

Busca-se a melhor compreensão dos mecanismos de lesão envolvendo resposta inflamatória mediada pelas citocinas para o desenvolvimento de novas estratégias protetoras. Pesquisou-se na base de dados PubMed, incluindo artigos relevantes, os unitermos "ventilator induced lung injury preterm", "continuous positive airway pressure", "preterm" e "bronchopulmonary dysplasia". Dados e informações significativas foram compilados em tópicos, com o objetivo de formar uma visão crítica e plena acerca da lesão induzida pela ventilação e de suas consequências ao prematuro. Foi revisado o papel das citocinas pró-inflamatórias como mediadores da lesão, especialmente interleucinas 6 e 8, e fator de necrose tumoral alfa. Foram apresentadas evidências em estudos com animais e também em humanos, mostrando que breves períodos de ventilação mecânica são suficientes para a liberação dessas interleucinas inflamatórias. Também foram revisadas outras formas de ventilação mecânica e de ventilação não invasiva, como alternativas protetoras aos modos convencionais. Concluiu-se que o uso de ventilação não invasiva, a intubação com administração precoce de surfactante e a extubação rápida para CPAP nasal, além de estratégias que regulam o volume corrente evitando o volutrauma (como a ventilação com volume garantido, são medidas protetoras da lesão pulmonar induzida pela ventilação mecânica no prematuro.

    Full Text Available El trasplante pulmonar es una alternativa terapéutica que se ha validado en lo últimos 30 años para aquellos pacientes portadores de una enfermedad pulmonar terminal. Las características propias del trasplante pulmonar dadas por su conexión al ambiente a través de la vía aérea y la isquemia presente en las suturas durante el primer mes han constituído por mucho tiempo la principal causa de morbilidad y mortalidad de los pacientes trasplantados pulmonares. Los nuevos medicamentos inmunosupresores, la mejoría de las soluciones de preservación y de las técnicas quirúrgicas han disminuido las complicaciones y mortalidad precoz, siendo el gran desafío aún, el rechazo crónico conocido como el Sindrome de Bronquiolitis Obliterante (SBO. La selección del receptor de acuerdo a la patología de base se ha modificado, promoviendo la derivación precoz en patologías como la fibrosis pulmonar y la fibrosis quística disminuyendo así la mortalidad en la lista de espera.

    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.

    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.

    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.

    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)

    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.

    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

    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.

    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.

    Full Text Available A pneumonectomia, embora seja tecnicamente simples, está associada a alta incidência de complicações (cerca de 60%. As complicações respiratórias correspondem a aproximadamente 15% deste total. A mortalidade global dessa cirurgia é de 8,6%, mas em presença de complicações respiratórias, a taxa de mortalidade chega a 30%. O edema pulmonar pós-pneumonectomia é uma complicação rara (3% a 5%, mas muito grave, sendo fatal na maioria dos casos. Foi descrito pela primeira vez há pouco mais de vinte anos mas, apesar da gravidade alarmante, pouco sabemos acerca de sua fisiopatologia, embora muitas hipóteses tenham sido levantadas. Uma vez instalado, nenhuma medida é comprovadamente eficaz no seu tratamento. Vários fatores de risco estão associados ao aparecimento do edema pulmonar pós-pneumonectomia, dentre os quais a sobrecarga hídrica, que foi o primeiro fator evitado. Entretanto, muitos trabalhos mostram não haver relação direta entre o volume recebido e o desenvolvimento do edema. A prevenção é a melhor forma de evitá-lo e deve ser realizada de maneira multifatorial, envolvendo toda a equipe médica, desde o momento da anestesia até os cuidados cirúrgicos e na terapia intensiva. No entanto, tão importante quanto a prevenção, é a suspeita clínica precoce, identificando os pacientes em risco para essa grave complicação.Although pneumonectomy is a technically simple procedure, it has been associated with a high (60% incidence of complications.

    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.

    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

PAP é caracterizada pela deposição de material lipoproteico secundário ao processamento anormal de surfactantes pelos macrófagos. Os pacientes podem ter dispneia progressiva e tosse, às vezes acompanhadas pelo agravamento da hipóxia, e seu curso pode variar de deterioração progressiva a melhora espontânea. Muitas terapias foram usadas, incluindo antibióticos, drenagem postural e ventilação com pressão positiva intermitente com acetilcisteína, heparina e soro fisiológico em aerossol. Atualmente, a base do tratamento é a lavagem pulmonar total (LPT. A LPT, embora seja geralmente bem-tolerada, pode estar associada a algumas complicações.

    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)

    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.

    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

    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 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 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 Os autores estudaram a existência de hemosiderose pulmonar em 60 casou de autopsia, 20 dos quais chagásicos crônicos com cardiopatia, 20 pacientes com cardiopatia não chagásica e 20 casos sem nenhuma manifestação de doença cardíaca. A incidência de hemossiderose pulmonar foi de 75% entre os chagásicos e de 80% entre os pacientes de cardiopatia não chagásica. Nos casos controle sem cardiopatia a incidência foi relativamente baixa (45% e, guando presente, o grau de intensidade era mínimo. Com esses achados, conclui-se que a hemossiderose pulmonar na Doença de Chagas é uma conseqüência da congestão crônica passiva, resultante da insuficiência cardíaca congestiva, do mesmo modo que ocorre em outras condições mórbidas tais como Estenose mitral e Cor-pulmonar crônico, não havendo evidências de uma pneumopatia peculiar em chagásicos.

Abstract: A 68 year old woman was submitted to a mediastinal lymphangioleiomyoma resection found in a follow-up study of lower left lung resection due to bronchiectasis complicated by chylothorax. This led to a revaluation of the pulmonary specimen that revealed, in addition to inflammatory bronchiectasis, small spindle cell nodules in the lung parenchyma, similar to minute pulmonary meningothelial-like nodules, but with smooth muscle actin immunohistochemical positivity. The possibility of initial pulmonary development of lymphangioleiomyomatosis is discussed.

    Conclusiones: El mantenimiento de FPAC no incrementa la morbimortalidad post-Glenn ni altera la conservación funcional del ventrículo único, permitiendo llegar a la fase pre-Fontan con mayor SaO2 y mejor tamaño de ramas pulmonares. La existencia o ausencia de FPAC no influyó en los resultados del Fontan posterior, aunque consideramos interesante mantenerlo, especialmente en casos con ramas pulmonares pequeñas. La paliación pre-Glenn tipo banding pulmonar se asoció a mayor imposibilidad de conservar un FPAC.

Os principais métodos de imagem utilizados no diagnóstico são representados por cintilografia ventilação-perfusão, angiografia pulmonar e tomografia computadorizada (TC. Na última década vários estudos têm demonstrado que a TC espiral apresenta elevada sensibilidade e especificidade no diagnóstico de tromboembolismo pulmonar agudo. Uma melhor avaliação das artérias pulmonares tornou-se possível com a recente introdução dos equipamentos de TC espirais com multidetectores. Vários pesquisadores têm sugerido que a angiografia pulmonar por TC espiral deve substituir a cintilografia na avaliação de pacientes com suspeita clinica de tromboembolismo pulmonar agudo. Os autores discutem os principais métodos de imagem utilizados no diagnóstico de tromboembolismo pulmonar agudo enfatizando o papel da TC espiral.The diagnosis of acute pulmonary thromboembolism is based on the clinical probability, use of D-dimer (when available and imaging. The main imaging modalities used in the diagnosis are ventilation-perfusion (V/Q, scintigraphy, angiography, and computed tomography (CT. In the last decade several studies have demonstrated that spiral CT has a high sensitivity and specificity in the diagnosis of acute pulmonary thromboembolism. The evaluation of the pulmonary arteries has further improved with the recent introduction of multidetector spiral CT scanners. Various investigators have suggested that spiral CT pulmonary angiography should replace scintigraphy in the assessment of patients whose symptoms are suggestive of acute PE. This article discusses the role of the various imaging modalities in the diagnosis of acute pulmonary thromboembolism with emphasis on the role of spiral CT.

La artritis reumatoide es una enfermedad inflamatoria crónica de las articulaciones, que afecta en un inicio la membrana sinovial, pero que si no es tratada oportunamente lleva a daño estructural irreversible del sistema músculo-esquelético y eventualmente de otros sistemas orgánicos. Dentro de los criterios de la American College of Rheumatology se incluyen la Rigidez Matutina, Artritis de 3 o más articulaciones, Artritis simétrica, Nódulos reumáticos, Factor Reumatoideo y hallazgos radiográficos. Dentro de la patogenia de esta enfermedad, el Factor de Necrosis Tumoral es una citocina que juega un papel importante, una producción elevada de TNF-α se ha encontrado en la sinovial de estos pacientes, y por su capacidad de inducir la producción de otras citocinas, como IL-6, IL-17, GM-CSF, M-CSF, e incluso IL-1 y TNF-α (función autócrina, parecería que el TNF-α ejerce una acción “jerárquica” dentro de la llamada red de citocinas y una inhibición de su acción da como resultado un beneficio terapéutico en los pacientes con AR. Sin embargo, es conocido que la infección concurrente más frecuentemente informada con el uso de agentes biológicos (Anti-TNF es la TB, y la incidencia de ésta se ha incrementado desde el advenimiento de la terapia biológica.

    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.

    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.)

    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.

    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.

    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

    Full Text Available Os hemangiomas congénitos rapidamente involutivos (RICH são tumores vasculares raros, que se caraterizam por um desenvolvimento completo ao nascimento e por uma regressão, habitualmente total e espontânea, entre seis a dezoito meses. O diagnóstico é clínico, por vezes auxiliado por exames de imagem e biópsia. 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.

    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.)

    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.

    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.

    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.

    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

    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.

    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.

    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.

    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.

    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

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.

    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.

    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.

    ✓ 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.

    Full Text Available Com o propósito de avaliar a segurança, a eficácia diagnóstica da biópsia pulmonar e comparar a possível ocorrência de complicações decorrentes da técnica, entre bezerros sadios e com broncopneumonia induzida, utilizaram-se dez bezerros (G1 sadios e vinte bezerros portadores de broncopneumonia, divididos em quatro grupos de cinco bezerros (G2 a G5, os quais foram biopsiados 12, 24, 48 e 72 horas após a inoculação com Mannheimia haemolytica, respectivamente. A presença de crepitação grossa, som submaciço à percussão e as alterações radiográficas auxiliaram no diagnóstico da broncopneumonia e localizaram a área pulmonar a ser biopsiada nos grupos G2 a G5. As alterações microscópicas, visualizadas nos animais do grupo G2 a G5, foram as de broncopneumonia fibrinopurulenta. Nos bezerros do grupo G1 as alterações relacionadas à técnica foram: tosse, epistaxe, dispneia mista, taquipneia e taquicardia. Cinco (25% bezerros com broncopneumonia desenvolveram hemotórax após a biópsia e as alterações relacionadas à técnica foram: taquipneia, taquicardia, tosse, dispneia mista, apatia, mucosas pálidas e decúbito. Conclui-se que a biópsia pulmonar permite o diagnóstico de broncopneumonia em bezerros, contudo as complicações decorrentes da técnica limitam o seu uso apenas nas situações em que os métodos convencionais não tenham possibilitado o diagnóstico.

    PALAVRAS-CHAVES: Bezerros, biópsia pulmonar, broncopneumonia, Mannheimia haemolytica.

    Full Text Available Os Autores descrevem um caso grave de esquistossomose mansoni (forma hepática com hipertensão portal associada a forma pulmonar com hipertensão pulmonar e cor pulmonalej sobre o qual evoluiu uma sindrome toxi-infectuosa grave e de longa duração. Sucessivos exames radiológicos do tórax revelaram acometimento predominantemente arteriolar, ao lado de uma micronodulação pulmonar grosseira e difusa em ambos os hemitóraces e configuração de coração pulmonar. A histopatologia de material de biópsia pulmonar identificou basicamente uma arterite pulmonar característica, inflamação granulomatosa atípica provocada principalmente por vermes e raros ovos de S. mansoni envolvidos por escassa reação inflamatória. Para explicar a origem de constelação clínica toxi-infectuosa, foram afastadas as hipóteses de associação da esquistossomose a concausas infectuosas ou não, mas de curso febril, e a superposição de uma forma toxêmica sobre outra crônica pré-existente. Com base em dados clínicos, particularmente em subsídios da laparoscopia, e anatômicos, concluiu-se tratar o caso de uma forma crônica de esquistossomose reativada, provavelmente em virtude de alterações imunológicas inusitadas do hospedeiro. Ao que tudo parece indicar, o desvio de ovos e de vermes aos pulmões deveu-se à sindrome de hipertensão portal, cujos shunts entre a circulação portal e sistêmica determinaram a rota preferencial da migração.

    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 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.

    Full Text Available Las enfermedades relacionadas al amianto se producen por la inhalación de fibras de asbestos en su variedad crisotilo o amianto blanco. A pesar de que en la Argentina la prohibición data del año 2003, existen numerosas industrias donde se sigue trabajando con este mineral, entre ellas las metalúrgicas y acerías. Actualmente se conoce la alta patogenicidad de este material, por lo que en muchos países existen programas de seguimiento de los trabajadores expuestos. Se describen las características generales y manifestaciones clínicas pulmonares de 27 pacientes que trabajaron en una gran acería de América del Sur. El diagnóstico de amiantopatías se realizó mediante historia clínica laboral, antecedente de exposición al amianto, estudios complementarios de función pulmonar e imágenes del tórax. Se analizaron la fuente de exposición (laboral, doméstica y ambiental, tiempo de exposición y período de latencia en los pacientes de los cuales se detectó enfermedad relacionada. Los antecedentes de tabaquismo fueron tenidos en cuenta para el análisis. En 22 pacientes se presentaron patologías benignas (81.4%, 16 de ellos tenían lesiones exclusivamente pleurales y otros 6 asbestosis. Las patologías malignas se presentaron en 5 pacientes (18.5%, en 4 fueron mesoteliomas y en uno carcinoma pulmonar. El problema de la exposición al amianto tiene vigencia actual. De ahí la necesidad de un programa de vigilancia en trabajadores expuestos al amianto actualmente o en el pasado, para detectar, notificar, registrar e investigar las características de estas patologías.

    Full Text Available Objetivo: caracterizar la prescripción de antimicrobianos en pacientes con diagnóstico de enfermedad pulmonar obstructiva crónica descompensada. Métodos: estudio descriptivo, de corte transversal, que incluyó a 131 pacientes con enfermedad pulmonar obstructiva crónica descompensada, a quienes se les prescribió algún antimicrobiano en salas de medicina interna del Hospital Clinicoquirúrgico "Joaquín Albarrán", La Habana, Cuba, entre mayo del 2011 y abril del 2012. Se identificaron las principales causas de exacerbación, se describió la prescripción de antimicrobianos y se determinó su relación con la severidad de la descompensación y con la estadía hospitalaria. Se analizaron los resultados obtenidos a través de programa estadístico SPSS. Resultados: el 65 % de los pacientes presentaron una descompensación infecciosa. La prescripción de antimicrobianos se realizó de forma empírica en el 92 % de los casos, e inadecuada en el 49 % de ellos. Se demostró la existencia de una relación estadísticamente significativa entre la severidad de la descompensación y la prescripción de antimicrobianos. Conclusiones: se prescribió antimicrobianos de manera inadecuada en cinco de cada diez pacientes con diagnóstico de enfermedad pulmonar obstructiva crónica descompensada, mayormente en aquellos casos sin haberse constatado diagnóstico positivo de infección respiratoria. A medida que disminuye la severidad de la descompensación, incrementa la incidencia de prescripción inadecuada.

    Full Text Available Patients with scleroderma are at increased risk for the development of pulmonary hypertension, and the development of unexplained dyspnea or an isolated decrease in diffusing capacity should prompt evaluation. Echocardiography is often helpful in this situation, with further testing being performed as indicated. Because the prognosis of untreated pulmonary hypertension occurring in the setting of scleroderma is generally quite poor, vigilance is required on the part of physicians following this "at risk" group of patients. The past decade has seen important advances in the treatment of pulmonary arterial hypertension, including intravenous epoprostenol, oral bosentan and subcutaneously infused treprostinil. As new therapies are developed for the treatment of pulmonary arterial hypertension, it is essential that patients with scleroderma-related disease are included in clinical trials.Pacientes com esclerodermia têm risco aumentado para desenvolver hipertensão pulmonar. O aparecimento de dispnéia e/ou a diminuição da capacidade de difusão devem levar à suspeita imediata dessa complicação. A ecodopplercardiografia é importante para o diagnóstico e o seguimento desses casos. Os casos não tratados de hipertensão pulmonar em esclerodermia têm mau prognóstico, daí a necessidade em manter sob vigilância estes pacientes. Na última década surgiram avanços para o tratamento da hipertensão arterial pulmonar, incluindo os medicamentos epoprostenol EV, bosentan VO e treprostinil SC. À medida que novas terapias vão sendo desenvolvidas, torna-se necessário a realização de estudos clínicos de maior validade.

    Full Text Available La investigación y el avance en el tratamiento de la hipertensión arterial pulmonar han permitido modificar la historia natural de esta enfermedad. El pilar del tratamiento es el empleo de terapias con vasodilatadores pulmonares específicos, pero también habrán de tenerse en cuenta otras medidas como la actividad física, el apoyo psicológico, la anticoagulación, el tratamiento diurético, la oxigenoterapia o el tratamiento anticonceptivo. Previo a iniciar cualquier tipo de tratamiento específico se requiere un estudio de vasorreactividad aguda del lecho vascular pulmonar, ya que los pacientes con respuesta positiva podrían beneficiarse del tratamiento con calcio-antagonistas. En caso de respuesta negativa o no ser respondedores sostenido, en la actualidad se dispone de fármacos frente a las tres principales vías metabólicas implicadas en el desarrollo de la enfermedad, a saber, prostanoides (epoprosterenol, treprostinil e iloprost, selexipag, antagonistas de los receptores de la endotelina o ARE (bosentan, macitentan y ambrisentan, inhibidores de la fosfodiesterasa 5 o IPDE5 (sildenafilo y tadalafilo y estimuladores de la guanilato ciclasa (riociguat. La elección del fármaco de inicio, ya sea en monoterapia o en combinación, dependerá de múltiples factores como clase funcional, comorbilidades, interacciones con otros fármacos, tolerabilidad y seguridad, y finalmente de la disponibilidad y las preferencias.

Fonte dos dados: Revisão na base de dados Pubmed com seleção de referências relevantes. Síntese dos dados: As DPOCC têm origem ambiental e/ou genética e se manifestam com diversos genótipos, fenótipos e endótipos e, embora possam ser controladas, não têm cura. O principal sintoma é a tosse crônica e muitas cursam com bronquiectasia. O manejo tem maior eficácia se baseado em guidelines e se a adesão ao regime terapêutico for estimulada e comprovada. Corticoides orais e inalatórios, broncodilatadores, antibióticos inalados e tratamento das exacerbações pulmonares (EP são vigas mestras do manejo e devem ser individualizados para cada DPOCC. Conclusões: Nas DPOCC é fundamental o diagnóstico correto, conhecer os fatores de risco e as comorbidades. Os procedimentos e os medicamentos devem ser baseados em guidelines específicos para cada DPOCC. Adesão ao tratamento é fundamental para obter os benefícios do manejo. O controle deve ser avaliado pela diminuição das EP, melhoria na qualidade de vida e redução da evolução da perda da função e do dano estrutural pulmonar. Para a maioria das DPOCC, o acompanhamento por equipes interdisciplinares em centros de referência especializados, com estratégias de vigilância e acolhimento contínuos, conduz a melhores desfechos, que devem ser avaliados pela diminuição da deterioração do dano e da função pulmonar, pelo melhor prognóstico, melhor qualidade de vida e aumento da expectativa de vida.

Pode ocorrer também em outras patologias do sistema nervoso central, tais como acidentes vasculares cerebrais (AVC, tumores ou após crises epilépticas, entre outras. Foram avaliados 36 casos com TCE grave e quatro pacientes com AVC, internados na UTI geral, no período de janeiro a setembro 1995. Nesse intervalo de tempo foram diagnosticados dois casos de edema pulmonar neurogênico, um ocorrendo em paciente com TCE grave e outro em paciente com AVC hemorrágico. O diagnóstico foi estabelecido pelo rápido desenvolvimento de edema pulmonar, com hipoxemia grave, queda da complacência pulmonar e infiltrados difusos bilaterais sem história prévia de aspiração traqueal ou outro fator de risco para o desenvolvimento de síndrome de angústia respiratória aguda. No primeiro paciente com trauma craniencefálico, o edema neurogênico foi diagnosticado na internação, uma hora após o trauma, com concomitante reação inflamatória grave e boa evolução em três dias. O outro caso, com AVC hemorrágico, desenvolveu edema neurogênico no quarto dia após drenagem de hematoma intraparenquimatoso, evoluindo para o óbito.Neurogenic pulmonary edema is a rare and serious complication in patients with head injury. It also may develop after a variety of cerebral insults such as subarachnoid hemorrhage, brain tumors and after epileptic seizures. Thirty six patients with severe head injury and four patients with cerebrovascular insults treated in Intensive Care Unit of HC-UNICAMP from January to September 1995 were evaluated. In this period there were two patients with neurogenic pulmonary edema, one with head injury and other with intracerebral hemorrhage. Diagnosis was made by rapid onset of pulmonary edema, severe hypoxemia, decrease of pulmonary complacence and diffuse pulmonary infiltrations, without previous history of tracheal

    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.

    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.

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

    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.

    Discusión: Se obtuvieron buenos resultados con la eliminación parcial del tumor, aliviando el ectropión mecánico. Se requiere un seguimiento cuidadoso ya que residuos tumorales pueden llegar a crecer como el tumor primario. La historia natural de los hemangiomas es tan característica que raramente se confunde con otras lesiones. Debe realizarse tratamiento quirúrgico cuando existe daño en la función palpebral o cuando la terapia farmacológica local no sea efectiva.

    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 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

    Full Text Available La hipertensión arterial pulmonar (HAP es una enfermedad crónica, que se caracteriza por el aumento de la resistencia vascular pulmonar (RVP a nivel de la arteriola pulmonar, que provoca una progresiva sobrecarga y posterior disfunción del ventrículo derecho (VD, que en etapas finales lleva a la insuficiencia cardiaca derecha, la cual sella su pronóstico. La HAP es más frecuente en mujeres jóvenes en plena edad productiva, siendo la supervivencia media de 2-3 años, antes de la aparición de terapias específicas. La base genética sugiere una herencia autosómica dominante con penetrancia incompleta, reconociéndose principalmente la afección del BMPR2. En la etiopatogenia se reconoce una alteración en las señales que controlan fundamentalmente el equilibrio vasocontrictor-vasodilatador a nivel del endotelio, con un desbalance hacia la proliferación y vasoconstricción, en las que están involucradas 3 vías patogénicas: La del Óxido nítrico (ON, de la Prostaciclina (PG y de la Endotelina (ET. El diagnóstico precoz de la HAP se asocia con una mejor supervivencia a largo plazo, por lo que su búsqueda ante un paciente con disnea, fatiga, dolor torácico y/o síncopes, así como en las poblaciones en riesgo, como son familiares en 1° con HAP, Esclerodermia y portadores de Hipertensión Portal, debería ser la estrategia de elección. La Ecocardiografía Doppler (ECO es la herramienta de pesquisa más utilizada en la práctica clínica actual. El diagnóstico debe ser confirmado mediante un cateterismo derecho, con mediciones directas de la presión arterial pulmonar, y debe realizarse prueba de vasoreactividad. El advenimiento de los tratamientos farmacológicos-HAP específicos ha provocado un cambio en la evolución natural de la enfermedad, existiendo hoy terapias orientadas a controlar las principales vías patogénicas involucradas: ON, PG, y ET.

    Full Text Available OBJETIVO: Apenas 15% dos pulmões doados são aproveitados para transplante. Um novo método de Perfusão Pulmonar Ex Vivo (PPEV foi desenvolvido e pode ser usado para avaliação e recondicionamento de pulmões "marginais" e rejeitados para o transplante. Esse trabalho relata nossa experiência com a avaliação funcional da PPEV. MÉTODOS: Foram estudados pulmões de 12 doadores considerados inapropriados para transplante pulmonar. Após a captação, os pulmões são perfundidos ex vivo com Steen Solution, uma solução de composição eletrolítica extracelular com alta pressão coloidosmótica. Um oxigenador de membrana ligado ao circuito recebe uma mistura gasosa (nitrogênio e dióxido de carbono e "desoxigena" o perfusato, mantendo uma concentração de gases semelhante a do sangue venoso. Os pulmões são gradualmente aquecidos, perfundidos e ventilados. A avaliação dos órgãos é feita por gasometrias e medidas como a resistência vascular pulmonar (RVP e complacência pulmonar (CP. RESULTADOS: A PaO2 (FiO2 100% passou de um valor médio de 193,3 mmHg no doador para 495,3 mmHg durante a PPEV. Após uma hora de PPEV, a RVP média era de 737,3 dinas/seg/ cm5 e a CP era de 42,2 ml/cmH2O. CONCLUSÕES: O modelo de avaliação pulmonar ex vivo pode melhorar a capacidade de oxigenação de pulmões "marginais" inicialmente rejeitados para transplante. Isso denota um grande potencial do método para aumentar a disponibilidade de pulmões para transplante e, possivelmente, reduzir o tempo de espera nas filas.OBJECTIVE: Only about 15% of the potential candidates for lung donation are considered suitable for transplantation.

    Full Text Available Se informa sobre la aplicación clínica exitosa de la técnica de anastomosis cava-pulmonar, originalmente descrito por Glenn y Patiño, en un caso de Tetralogía de Fallot. Representa este caso el primer paciente tratado en esta forma en la literatura médica occidental. La anastomosis cava-pulmonar es un procedimiento técnicamente muy sencillo que permite mejorar notablemente la oxigenación en pacientes que presentan ciertas anomalías en el corazón derecho o en la arteria pulmonar. La anastomosis cava-pulmonar parece ser una operación fisiológica fácil de realizar, bien tolerada, que da como resultado buena oxigenación de la sangre venosa desembocada al pulmón derecho, y que en el caso de la Tetralogía de Fallot, presenta notables ventajas sobre las operaciones paliativas clásicas de Blalock y Potts. La anastomosis cava-pulmonar es un procedimiento que puede ser usado en el tratamiento quirúrgico de la Tetralogía de Fallot como operación paliativa definitiva, o como la primera etapa que mejora las condiciones generales del paciente para permitir que más tarde pueda ser llevado a corrección definitiva. Esta anastomosis, que disminuye trabajo al corazón, no necesariamente tiene que ser deshecha a tiempo de la corrección definitiva, a diferencia de las operaciones clásicas de Blalock y Pott, que sí añaden trabajo al corazón al crear un ductus artificial y una hipertensión pulmonar. Se propone el uso clínico de la anastomosis cava-pulmonar en aquellos casos de Tetralogía de Fallot que requieran una operación paliativa extra-cardíaca o como la primera etapa antes de ser sometidos a la corrección definitiva por circulación extracorpórea.

    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)

    Full Text Available Em situações específicas, os transplantes clínicos cardiopulmonar e pulmonar são, hoje, formas estabelecidas de tratamento para estágio final de doença cardiopulmonar e pulmonar. A obtenção de doadores adequados permanece o maior problema e a remoção de órgãos em localidades distantes é, hoje, uma necessidade. Embora muitos métodos de preservação pulmonar possam ser empregados, para períodos isquémicos de até 5 horas, a hipotermia e o uso de solução cardioplégica com infusão da solução de Collins modificada no tronco pulmonar tem sido método simples e eficiente para preservação do bloco coração-pulmão. Descrevemos, aqui, o método corrente que empregamos, com o qual os transplantes cardiopulmonar e pulmonar combinados foram sucedidos de excelente função cárdio-respiratória.In special situations, clinical heart-lung and lung transplantation are today established methods of therapy for end stage cardiopulmonary and pulmonary disease. Adequate donor availability remains a major problem and distant organ procurement is today a necessity. Although many methods of lung preservation can be used, for periods of up to 5 hours, hypothermic storage with cardioplegic arrest and pulmonary artery flush with modified Collins solution has proven to be a simple and reliable method of heart-lung preservation. We here describe our current method of heart-lung block protection, in which heart-lung and double lung transplantation were performed followed by excelent cardiac and pulmonary function.

    Full Text Available OBJETIVO: O aumento da sobrevida de prematuros traz o desafio de lidar com um amplo espectro de doenças pulmonares crônicas, incluindo displasia broncopulmonar, síndrome de Wilson-Mikity e sibilância recorrente. Este artigo discute o prognóstico pulmonar clínico e funcional de prematuros na infância e na adolescência. FONTE DE DADOS: Foi realizada pesquisa no MEDLINE de publicações entre 1970 e 2004 que abordassem função e crescimento pulmonar de prematuros, bem como a evolução clínica dos mesmos. SÍNTESE DOS DADOS: Eventos pré e pós-natais como insuficiência placentária, tabagismo, infecções, oxigênio e ventilação mecânica exercem efeitos importantes no desenvolvimento pulmonar, podendo conduzir a doenças pulmonares crônicas, sendo a displasia broncopulmonar a complicação clínica mais severa. No entanto, perdas significativas de função pulmonar também podem ocorrer em prematuros sem critérios de displasia broncopulmonar e que não apresentaram doença respiratória neonatal significativa. Nestes pacientes, o impacto da prematuridade sobre o sistema respiratório é freqüentemente subestimado. Clinicamente, observa-se incidência aumentada de pneumonias e bronquiolites, re-hospitalizações por doenças respiratórias, tosse e sibilância crônicas e hiper-reatividade brônquica. Posteriormente, percebe-se uma tendência à normalização da função pulmonar, mas persistem fluxos reduzidos, menor tolerância a exercícios e hiper-reatividade brônquica. CONCLUSÕES: A prematuridade, os eventos que a provocam e as intervenções que dela decorrem alteram de maneira permanente, em maior ou menor grau, o desenvolvimento do sistema respiratório. São necessários estudos adicionais para esclarecer o efeito de cada um desses insultos perinatais no desenvolvimento do sistema respiratório.OBJECTIVE: The increased survival of preterm infants poses the challenge of dealing with a wide range of chronic pulmonary

    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

    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)

    2005-02-01

    Full Text Available INTRODUÇÃO: A adenosina é um nucleosídeo com potente ação vasodilatadora. Apesar de seus efeitos sobre o território arterial pulmonar ser conhecido, seu efeito sobre o território capilar/venoso ainda não foi descrito. OBJETIVO: Estudar o comportamento das resistências arterial e venosa da circulação pulmonar de pacientes com hipertensão pulmonar primária antes e depois da administração de adenosina. MÉTODO: Foram estudados sete pacientes com hipertensão pulmonar primária que apresentaram resposta positiva durante o teste agudo com adenosina. Resistência arterial e resistência venosa foram determinadas pela estimativa da pressão capilar pulmonar realizada através da análise da curva de decaimento da pressão arterial pulmonar, antes e depois da administração da adenosina. RESULTADOS: Após a administração da adenosina, houve um aumento do índice cardíaco (1,71 ± 0,23 para 2,72 ± 0,74 L.min-1.m-2 com concomitante diminuição da resistência vascular pulmonar (2.924 ± 1.060 para 1.975 ± 764 dina.s.cm-5.m-2, sem variações significativas da pressão arterial pulmonar média (75,6 ± 16,8 para 78,1 ± 18,8 mmHg, da pressão de oclusão da artéria pulmonar (15,3 ± 1,5 para 15,4 ± 1,9 mmHg e da pressão capilar pulmonar (43,8 ± 5,8 para 44,5 ± 4,9 mmHg. A proporção entre a resistência arterial e a resistência vascular pulmonar total também apresentou variação não significativa (50 ± 15 para 49 ± 17%. Estes achados sugerem que a adenosina teve ação não somente sobre o território arterial mas também sobre o território capilar/venoso. CONCLUSÃO: Os autores concluem que o mecanismo de ação da adenosina não é restrito ao território arterial da circulação pulmonar e que este tipo de análise, através da determinação da pressão capilar pulmonar, pode ser útil no estudo das diversas drogas que agem sobre a circulação pulmonar.BACKGROUND: The nucleoside adenosine is a potent vasodilator

    es uno de los metodos mas utiles para el estudio de las alteraciones de.la circulacion pulmonar y para el diagnostico de embolias e infartcs. Sin embargo su utilizacion en diagnostico tumoral apenas si ha pasado de algunos ensayos. Los autores han centrado su atencion en el estudio, mediante gammagrafia, de pacientes con tumores de pulmon primitivos y secundarios a otras localizaciones, encontrando que segun el tipo de tumor el patron de distribucion del trazador es radicalmente distinto. En los tumores metastasicos la repercusion de las lesiones en la gammagraffa es pequena y depende exclusivamente del volumen de la zona de condensacion. Los nodulos tumorales se comportan exclusivamente como zonas inactivas dentro de una masa de parenquima funcional activo y su influencia en la imagen gammagrafica depende exclusivamente del tamano de la zona tumoral y de la cantidad de parenquima sano que se interponga entre ella y el detector. En los tumores pulmonares primitivos y muy especialmente en los localizados en la zona hiliar, lesiones relativamente pequenas originan defectos de captacion amplias zonas del pulmon, que pueden afectar a varios segmentos, a un lobulo e incluso a la totalidad del pulmon. Esta disminucion de captacion no puede explicarse exclusivamente por la imagen tumoral, ni por las zonas de atelectasia asociadas, sino que debe ser motivada por una modificacion profunda de la hemodinamica del puimon afecto. Varios tipos de fenomenos asociados a la progresion tumoral pueden motivar alteraciones vasculares que afecten hasta la periferia del pulmon: la alteracion del regimen ventilatorio con disminucion de la tension de oxigeno que da lugar a una modificacion de las condiciones hemodinamicas; la hipertension pulmonar por compresion de las venas pulmonares de menor resistencia que las arterias; y el estimulo nervioso directo por irritacion de los plexos bronquiales por el crecimiento del tumor y los fenomenos reactivos asociados.

    Pulmonary involvement in systemic sclerosis. Alveolitis, fibrosis and pulmonar arterial hypertension Lung disease is present in most of the patients with systemic sclerosis and is now the most important cause of mortality. Interstitial lung disease and pulmonary hypertension are, so far, the main disorders found and both are difficult to detect at the earliest stages. However, diagnostic tools such as immunological test, lung function test, high resolution CT, bronchoalveolar lavage, echocardiography, right-side cardiac catheterization, or lung biopsy are necessary to accurately evaluate the clinical status and allow to improve the management organ-specific ad hoc.

    Full Text Available A síndrome pulmonar e cardiovascular por hantavírus é uma doença de conhecimento relativamente recente e freqüentemente fatal, apresentando-se como síndrome do desconforto respiratório agudo. No Brasil, desde o primeiro surto, relatado em novembro/dezembro de 1993, em Juquitiba, 226 casos já foram registrados pela Fundação Nacional da Saúde. A doença afeta indivíduos previamente hígidos, apresentando-se com pródromo febril e sintomas semelhantes aos de um resfriado comum, podendo rapidamente evoluir para edema pulmonar, insuficiência respiratória aguda e choque. A hemoconcentração e a plaquetopenia são comuns da síndrome pulmonar e cardiovascular por hantavírus, e o quadro radiológico típico é de um infiltrado intersticial bilateral difuso, que progride rapidamente para consolidações alveolares, paralelamente à piora do quadro clínico. A mortalidade inicial era em torno de 75% e declinou para aproximadamente 35%, nos últimos anos. Os pacientes que sobrevivem geralmente recuperam-se completamente, cerca de uma semana após o estabelecimento do quadro respiratório. O agente causal, não reconhecido até há pouco, foi identificado como um hantavírus, cujo reservatório natural são animais roedores da família Muridae, subfamília Sigmodontinae. O tratamento específico antiviral ainda não é bem estabelecido, estando em estudo a eficácia de ribavirina. Cuidados de terapia intensiva como ventilação mecânica e monitoramento hemodinâmico invasivo são necessários nas formas mais graves da doença. Essas medidas, se instituídas precocemente, podem melhorar o prognóstico e a sobrevida dos pacientes com síndrome pulmonar e cardiovascular por hantavírus.Hantavirus pulmonary and cardiovascular syndrome is a recently identified and often fatal disease, which presents as acute respiratory distress syndrome (ARDS.

    2016-06-01

    Full Text Available La hipertensión pulmonar persistente del recién nacido es el resultado de un fracaso o de una mala adaptación circulatoria al momento de nacimiento; y representa una falla respiratoria aguda con un aumento sostenido de la resistencia vascular pulmonar, generando cortos circuitos extrapulmonares de derecha a izquierda, a través del conducto arterioso y foramen oval, con hipoxemia severa y acidosis secundaria. La clave del tratamiento reside en lograr una rápida mejoría de la oxigenación y dilatación de la arteria pulmonar para revertir los cortos circuitos con el uso de vasodilatadores pulmonares, de los cuales el óxido nítrico es el único agente aprobado por la FDA para su uso en neonatos con hipertensión pulmonar persistente del recién nacido, y debe ser considerado como el tratamiento de primera línea. Esta revisión se centrará en qué es el óxido nítrico y su papel como tratamiento de la hipertensión pulmonar persistente del recién nacido.

    Full Text Available La altura constituye un fascinante laboratorio natural para la investigación médica. Si bien al principio el objetivo de la investigación en la altura fue la comprensión de los mecanismos de adaptación del organismo a la hipoxia y la búsqueda de tratamientos para las enfermedades relacionadas con la altura, durante la última década el alcance de esta investigación se ha ampliado considerablemente. Dos importantes observaciones han generado las bases para el crecimiento del alcance científico de la investigación en la altura. Primero, el hecho de que el edema pulmonar agudo de la altura constituye un modelo único para estudiar los mecanismos fundamentales de la hipertensión pulmonar y el edema pulmonar en humanos. Segundo, que la hipoxia ambiental asociada con la exposición a la altura facilita la detección de disfunción vascular pulmonar y sistémica en un estadio precoz. Aquí revisaremos los estudios que, capitalizando estas observaciones, han llevado a la descripción de nuevos mecanismos subyacentes del edema pulmonar y de la hipertensión pulmonar, y a la primera demostración directa de la existencia de una programación fetal sobre la disfunción vascular en humanos.

    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.

    Resumen

    El surfactante pulmonar es una sustancia tensoactiva producida por los neumocitos tipo II, cuya concentración en el recién nacido prematuro/ inmaduro está disminuída, llevando a la producción del síndrome de dificultad respiratoria. El surfactante está constituído en un 85% por lípidos, del tipo fosfolípidos en su mayoría. El resto son proteínas surfactantes.

    Los fosfogliceridos (lecitinas y la esfingomielina forman el grupo de fosfolipidos involucrados. La fosfatidil colina y la dipalmitoil fosfatidil colina son las lecitinas más abundantes en el líquido extracelular que recubre los alvéolos pulmonares normales y en el surfactante pulmonar que disminuye su tensión superficial. Así se evita la atelectasia al final de la fase espiratoria de la respiración. En el neumocito II, enzimas remodelan las diferentes lecitinas para convertirlas en dipalmitoil fosfatidil colina.

    Una vez que el surfactante es producido en el neumocito, esta substancia migra como “cuerpos la melares” desde el núcleo hasta la superficie apical de la célula desde donde es liberado por exocitosis dentro del alveolo.

    Menos de un 0.1% de los recién nacidos presentan Síndrome de Dificultad Respiratoria (llamado antiguamente Enfermedad de Membrana Hialina cada año, y alrededor de un 10 % de estos mueren. La administracion de corticoesteroides incrementa la madurez pulmonar en casos de riesgo de parto prematuro, o cuando es necesario realizar una cesárea lo más temprano posible. El tratamiento de los bebes prematuros que presentan SDR incluye la administración de surfactantes dentro del árbol traqueobronquial.

    El patrón oro de la determinación de madurez pulmonar fetal es la relación lecitina/esfingomielina (L/E, aunque hay algunas otras pruebas como la medición de cuerpos la melares, que resultan confiables, económicas y más fácilmente disponibles en hospitales de menor categor

    A 32-year-old woman in whom basal cell epithelioma (BCE) arose on the P-32 irradiated area is reported. At the age of 2, the patient had received superficial irradiation with P-32 for hemangioma simplex on the right precordial site. A black, ill-defined mass has occurred and gradually increased 3 years earlier. Chronic radiodermatitis characterized by teleangiectasis and skin atrophy was seen in the area surrounding the mass, which corresonded to that exposed to P-32. Histopathological examination leads to the diagnosis of BCE developing in part of chronic radiodermatitis. Review of the literature shows 3 cases of squamous cell carcinoma of the skin resulting from P-32 therapy. This is the first report on a patient with BCE resulting from irradiation with P-32.

Entretanto, em pacientes hemodinamicamente estáveis, a associação de algumas variáveis clínicas com a mortalidade ainda não está claramente estabelecida. OBJETIVOS: Derivar um modelo de estratificação do risco de mortalidade intra-hospitalar em pacientes com embolia pulmonar hemodinamicamente estáveis. MÉTODOS: Estudo de coorte multicêntrico prospectivo de 582 pacientes consecutivos que foram admitidos em unidades de emergência ou de terapia intensiva, com suspeita clínica de embolia pulmonar, e que tiveram o diagnóstico confirmado por meio de um ou mais dos seguintes exames: arteriografia pulmonar, angiotomografia computadorizada helicoidal, angioressonância magnética, ecodopplercardiograma, cintilografia pulmonar ou duplex-scan venoso. Os dados sobre características demográficas, comorbidades e manifestações clínicas foram coletados e incluídos em uma análise de regressão logística para compor o modelo de predição. RESULTADOS: A mortalidade global foi de 14,1%. Foram identificadas como variáveis independentes de risco de óbito: idade > 65 anos; repouso no leito > 72h; cor pulmonale crônico; taquicardia sinusal e taquipnéia. Após a estratificação por faixas de risco, observaram-se mortalidades de 5,4%, 17,8% e 31,3%, respectivamente nos subgrupos de baixo, moderado e alto riscos. O modelo mostrou sensibilidade de 65,5% e especificidade de 80%, com uma área sob a curva de 0,77. CONCLUSÃO: Em pacientes hemodinamicamente estáveis com embolia pulmonar, a idade > 65 anos, o repouso no leito > 72h, o cor pulmonale crônico, a taquicardia sinusal e a taquipnéia foram preditores independentes da mortalidade intra-hospitalar.

  7. [Clinical aspects and therapy of lymphangiomas, hemangiomas and nevi in the area of the head and neck].

    Science.gov (United States)

    Drepper, H

    1985-07-01

    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

    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

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.

RESULTADOS: Ambos reduziram a hipertensão pulmonar, porém o nitrato promoveu hipotensão sistêmica significativa (Pressão Arterial Média - PAM: 85,2 vs. 69,8 mmHg, p < 0,001. Ambos reduziram as dimensões cardíacas e melhoraram a função cardíaca esquerda (NPS: 23,5 vs. 24,8 %, p = 0,02; SIL: 23,8 vs. 26 %, p < 0,001 e direita (SIL: 6,57 ± 2,08 vs. 8,11 ± 1,81 cm/s, p = 0,002; NPS: 6,64 ± 1,51 vs. 7,72 ± 1,44 cm/s, p = 0,003, medidas pela fração de ejeção ventricular esquerda e Doppler tecidual, respectivamente. O SIL, ao contrário do NPS, apresentou melhora no índice de saturação venosa de oxigênio, medido pela gasometria venosa. CONCLUSÃO: Sildenafil e NPS são vasodilatadores que reduzem, de forma significativa, a hipertensão pulmonar e a geometria cardíaca, além de melhorar a função biventricular. O NPS, ao contrário do SIL, esteve associado a hipotensão arterial sistêmica e piora da saturação venosa de oxigênio.

    Full Text Available OBJETIVO: Estudar, retrospectivamente, as várias formas de apresentação da cicatriz radial/lesão esclerosante complexa (CR/LEC na mamografia, correlacionando-as com o exame clínico e os achados ultra-sonográficos. Os achados histopatológicos e a associação da CR/LEC com hiperplasia atípica e carcinoma são discutidos. MATERIAIS E MÉTODOS: Foi realizado estudo retrospectivo de 926 lesões impalpáveis em 901 pacientes submetidas a biópsia excisional após localização pré-cirúrgica, do arquivo do Centro de Diagnóstico por Imagem e do Hospital Santa Rita, Vitória, ES, no período de outubro de 1993 a dezembro de 2001, nas quais 57 pacientes tiveram diagnóstico histopatológico de CR/LEC. RESULTADOS: A idade variou de 31 a 84 anos (média de 49 anos. As lesões foram palpáveis em dez casos. Na mamografia, 48 casos se apresentaram como distorção arquitetural, e com a mesma freqüência o nódulo espiculado e a densidade assimétrica, quatro casos cada. As microcalcificações foram detectadas na mamografia em 14 casos e em 20 quando o espécime cirúrgico foi avaliado. A ultra-sonografia foi realizada em 51 casos, tendo expressão em 17 como área hipoecóica irregular com atenuação acústica posterior. Houve 42 casos de CR/LEC sem ou com proliferação típica, nove casos com proliferação epitelial atípica e seis casos com carcinoma infiltrativo associado. CONCLUSÃO: Não é possível fazer diagnóstico diferencial de CR/LEC com câncer pelos métodos de imagem e a biópsia excisional deve ser realizada.OBJECTIVE: To review the different types of radial scar/complex sclerosing lesion (RS/CSL seen on clinical, mammography, and ultrasound examinations.

Casuística e Métodos: Foram operados 2 pacientes nos quais se empregou a técnica de anastomose cavo-pulmonar total, sem uso de material protético. O primeiro caso, A.L.M., masc, 4 anos, 15 kg, era portador de atresia tricúspide (EP, com comunicação interventricular (CIV restritiva. O segundo caso, M.E.N.O., fem, 15 anos, 47 kg, tinha doença de Ebstein. O controle pós-operatório dos pacientes foi feito com ecocardiograma e cateterismo cardíaco. As operações foram realizadas com o emprego de circulação extracorpórea (CEC, e cardioplegia sangüínea como método de proteção miocárdica. A canulação das cavas foi o mais distal possível. A tunelização foi realizada com retalho de tecido atrial direito, suturado ao septo interatrial, deixando-se o seio coronariano e a comunicação interatrial (CIA para a esquerda. Resultados: Ambos os pacientes evoluíram, sem complicações, na UTI. O primeiro apresentou derrame pleural discreto à direita, e o segundo mantém-se em estimulação artificial (VVI,R. Conclusões: A tunelização intra-atrial para anastomose cavo-pulmonar total pode ser realizada sem o uso de material protético, evitando-se os riscos advindos do seu emprego (calcificação, retração, embolização.The authors describe two cases (one tricuspid atresia without TGA or pulmonary stenosis, but with a restrictive IVC: the second of an Ebstein disease of total cavo-pulmonary anastomosis using only the tissue of the atrial wall, avoiding any prosthetic material.

    Full Text Available Com uma incidência de 3 a 10% dos casos e letalidade próxima a 70%, o comprometimento pulmonar constitui uma das manifestações mais graves da malária por Plasmodium falciparum. Embora sua patogênese não esteja perfeitamente esclarecida, reconhece-se que a hiperativação do sistema imune por antígenos liberados pelo Plasmodium falciparum desempenhe um importante papel no desencadeamento e agravamento das lesões. A estrutura alvo parece ser o endotélio capilar, responsável pelo fluxo de líquidos para o espaço intersticial. Essas células são ativadas por ação de citocinas, produzidas por linfócitos e macrófagos durante a resposta imune, e passam a expressar em sua membrana celular receptores e moléculas de aderência que facilitam a sequestração de eritrócitos parasitados e também a aderência de células capazes de produzir mediadores inflamatórios. A reação inflamatória e a lesão endotelial que se seguem, juntamente com as alterações hemodinâmicas induzidas pelo bloqueio capilar devido ao acúmulo local de eritrócitos e células inflamatórias causam alterações de permeabilidade vascular e, consequentemente, acúmulo de líquido nos espaços intersticiais e alvéolos. Nos casos mais graves, as manifestações clínicas assemelham-se às do quadro da Síndrome do desconforto respiratório do adulto. Comprometimento pulmonar grave pode se instalar rapidamente em qualquer estágio da evolução clínica da malária, mesmo após a cura parasitológica, desconhecendo-se os fatores desencadeantes. Hiperparasitismo, insuficiência renal e gravidez constituem fatores predisponentes. O prognóstico dependerá da rapidez com que o diagnóstico for estabelecido e o correto tratamento instituído. Além do tratamento instituído contra o parasita, especial atenção deverá ser dispensada à monitorização hemodinâmica, se possível através de cateter de Swan-Ganz, à manutenção de adequada oxigenação e balanço h

    Paula Hino

    Full Text Available O presente estudo teve como objetivo conhecer as percepções sobre necessidades em saúde de pessoas com tuberculose pulmonar. Trata-se de estudo qualitativo, desenvolvido no distrito administrativo Capão Redondo, São Paulo. Os dados foram coletados em janeiro de 2010 por meio de entrevista semidiretiva. Foram entrevistadas onze pessoas em tratamento contra tuberculose, com idade mínima de 18 anos e sem limites de cognição. O material empírico foi decodificado a partir de técnica de análise de discurso. As percepções sobre necessidades em saúde estão relacionadas às dificuldades enfrentadas no processo saúde-doença, e o reconhecimento das necessidades em saúde mostrou-se condicionado à vigência do agravo à saúde. As necessidades identificadas decorrem de alterações biológicas, do cotidiano e de insuficiências no processo de produção dos serviços de saúde. A qualidade da assistência às pessoas com tuberculose está, entre outros fatores, condicionada à identificação e ao atendimento de suas necessidades em saúde.

    Full Text Available RESUMO Tuberculose é uma doença infecciosa causada pelo Mycobacterium tuberculosis, também conhecido como bacilo de Koch. O principal sítio de acometimento é o pulmonar, porém o bacilo pode disseminar-se por via linfo-hematogênica para outros órgãos, dentre eles o olho. A incidência de tuberculose ocular é de 1 a 2% dos casos extrapulmonares. Os autores apresentam um caso clínico de um paciente do sexo feminino de 28 anos que procura atendimento médico devido à redução da acuidade visual em olho esquerdo há 7 dias. Apresentava a melhor acuidade visual corrigida no olho acometido de 20/200 e no olho contralateral de 20/20. Na fundoscopia era evidenciado um granuloma em área macular do olho esquerdo, com edema e hemorragia intrarretiniana adjacente. Após investigação diagnóstica, a paciente foi tratada com esquema antibiótico para tuberculose durante 6 meses, obtendo regressão do granuloma e melhora da acuidade visual deste olho para 20/50.

    Full Text Available La tuberculosis es una enfermedad que implica un riesgo ocupacional para el personal de salud que atiende a este tipo de pacientes, debido a que el agente Mycobacterium tuberculosis es eliminado hacia el ambiente a través de diferentes acciones como la tos, el estornudo, el acto de escupir, cantar o incluso la conversación. Las pequeñas gotas que se generan se evaporan rápidamente y se convierten en aerosoles de pequeñas partículas que, por su tamaño (1 a 3 μm, permanecen en suspensión y pueden ser transportadas, según el flujo del aire, a través de la habitación o de un edificio. El tamaño reducido facilita su llegada a los alvéolos pulmonares y el riesgo de transmisión está confinado a los que comparten lugares cerrados y mal ventilados, debido a la gran concentración de aerosoles en ese espacio.

Evoluiu com importante regurgitação valvar pulmonar (RVP e disfunção do ventrículo direito. Na reoperação foi implantado homoenxerto pulmonar criopreservado (HPC com anuloplastia, utilizando anel de Delrin com o intuito de evitar distorção geométrica do conduto. Após dois anos, o ecocardiograma, semelhante ao pós-operatório imediato, demonstra RVP discreta e função ventricular direita normal, sugerindo que essa manobra pode ser utilizada como coadjuvante para otimizar o resultado do implante do HPC.A six-year-old child was suffering from pulmonary atresia with ventricular septal defect after a total correction at 1 year of age using a bovine pericardial monocusp valve in the reconstruction of the right ventricle outflow tract. The infant evolved with significant pulmonary valve regurgitation (PVR and right ventricle dysfunction. On reoperation, a cryopreserved pulmonary homograft (CPH was implanted with annuloplasty utilizing a Delrin ring with the aim of avoiding geometric distortion of the vessel. After two years, an echocardiogram proved a similar state to the immediate postoperative period with slight pulmonary valve regurgitation and normal right ventricular function suggesting that this maneuver may be used as coadjuvant treatment to optimize the result of CPH implantation.

Sucessivos exames radiológicos de tórax revelaram comprometimento predominantemente arteriolar ao iado de uma micronodulação delicada e difusamente distribuída e configuração de cor pulmonale. Ao contrário do caso anteriormente descrito, a evolução se deu sem que se verificassem manifestações febris. Embora tenham sido afastadas várias hipóteses de associação da esquistossomose a concausas infectuosas, optou-se pelo tratamento de prova da tuberculose pulmonar. O fundo de olho também apresentava vários nódulos esbranquiçados disseminados pelo coróide e retina, caracterizando provável coroidite e retinite esquistossomótica. O tratamento antituberculoso resultou praticamente nulo. Não se procedeu ao tratamento específico da esquistossomose, considerando-se o alto risco da cardiopatia face aos esquistossomicidas disponíveis. A alta foi fornecida após treze meses de observação hospitalar. Não compareceu a ulterior controle.

    2018-03-01

    Full Text Available Resumen: La hipertensión pulmonar tromboembólica crónica se considera el único tipo de hipertensión pulmonar con un tratamiento quirúrgico potencialmente curativo. Aun hoy está infradiagnosticada o con frecuencia diagnosticada tardíamente, comportando un empeoramiento del pronóstico. La hipertensión pulmonar tromboembólica crónica se presenta con síntomas poco específicos y los médicos de atención primaria pueden no ser conscientes de su presencia o del potencial tratamiento. El tratamiento médico actual es, en el mejor de los casos, paliativo. La endarterectomía pulmonar ofrece la única posibilidad de mejora sintomática y pronóstica, siendo curativa en la mayoría de los casos a corto y a largo plazo. Por lo tanto, no solo la identificación de la enfermedad puede ser difícil y tardía sino que incluso después de que el diagnóstico se haya establecido, la evaluación de la operabilidad puede ser un reto. La operabilidad se basa en la estimación preoperatoria de la clasificación quirúrgica y de la probable resistencia vascular pulmonar postoperatoria, las cuales determinan el riesgo de la intervención y el posible resultado. Este complejo procedimiento que va desde la caracterización de la enfermedad a la intervención quirúrgica pasando por todo el proceso decisional, requiere una colaboración multidisciplinar de expertos en hipertensión pulmonar, con un equipo quirúrgico dedicado a este campo y con protocolos bien precisos. En nuestro centro, hemos construido un equipo especializado que incluye radiólogos, cardiólogos, cirujanos cardiacos, anestesistas/intensivistas y fisioterapeutas, que no solo ha permitido obtener resultados quirúrgicos comparables a centros europeos de más alto volumen, sino que también ha permitido desarrollar e implementar otras opciones terapéuticas como la angioplastia pulmonar con balón, dedicadas a los pacientes de alto riesgo descartados para la cirugía.En el siguiente art

    Full Text Available OBJETIVO: Analisar as características morfométricas das artérias pulmonares centrais e artérias colaterais sistêmico-pulmonares, avaliando a morfologia do suprimento sangüíneo vascular pulmonar, procurando estabelecer suas implicações no tratamento cirúrgico. MÉTODO: Entre janeiro/1990 e junho/2001, foram estudados 40 pacientes, incluíndo-se os que apresentavam estudo cineangiocardiográfico completo e prévio à primeira intervenção cirúrgica. Analisaram-se as características morfométricas das artérias pulmonares centrais e artérias colaterais sistêmico-pulmonares, assim como a distribuição da irrigação sangüínea nos pulmões. Calcularam-se os índices arterial pulmonar (IAAPP, arterial colateral sistêmico-pulmonar (IACSP e arterial neopulmonar total (IANPT = IAAPP + IACSP. O tratamento cirúrgico foi considerado paliativo (TP, paliativo definitivo (TPD e definitivo (TD. RESULTADOS: O TP foi predominante. Não houve diferenças estatisticamente significantes entre os pacientes com TP, TPD e TD, em relação ao IAAPP, IACSP e IANPT. Comparando o IAAPP e o IACSP, não houve diferença entre os índices para o TD (p=0,4309, o IACSP foi maior que o IAAPP para o TP (p=0,0176 e descritivamente também maior para o TPD. O IANPT dos pacientes em TD foi maior que os em TP (p=0,0959. Foram identificados cinco subgrupos morfologicamente semelhantes, denominados: B1, B2, B3, B4 e B5. A mortalidade total foi de 17,5%. CONCLUSÃO: A morfologia do suprimento sangüíneo vascular pulmonar das artérias pulmonares centrais e artérias colaterais sistêmico-pulmonares mostrou-se soberana na orientação do tratamento cirúrgico. Independentemente da divisão didática em subgrupos, o TP foi predominante.

Sucessivos exames radiológicos do tórax revelaram acometimento predominantemente arteriolar, ao lado de uma micronodulação pulmonar grosseira e difusa em ambos os hemitóraces e configuração de coração pulmonar. A histopatologia de material de biópsia pulmonar identificou basicamente uma arterite pulmonar característica, inflamação granulomatosa atípica provocada principalmente por vermes e raros ovos de S. mansoni envolvidos por escassa reação inflamatória. Para explicar a origem de constelação clínica toxi-infectuosa, foram afastadas as hipóteses de associação da esquistossomose a concausas infectuosas ou não, mas de curso febril, e a superposição de uma forma toxêmica sobre outra crônica pré-existente. Com base em dados clínicos, particularmente em subsídios da laparoscopia, e anatômicos, concluiu-se tratar o caso de uma forma crônica de esquistossomose reativada, provavelmente em virtude de alterações imunológicas inusitadas do hospedeiro. Ao que tudo parece indicar, o desvio de ovos e de vermes aos pulmões deveu-se à sindrome de hipertensão portal, cujos shunts entre a circulação portal e sistêmica determinaram a rota preferencial da migração.The Authors relate a case ofsevere schistosomiasis mansoni (hepatic form, with portal hypertension, associated with pulmonary form, with pulmonary hypertension and cor pulmonale, o ver which develloped a severe toxi-infectious syndrome of long duration.

    Full Text Available Embora diagnósticos de fibrose pulmonar idiopática continuem sendo devastadores, avanços recentes têm melhorado nossa compreensão a respeito de muitas das facetas desta doença. Estas descobertas, juntamente com o aumento da disponibilidade geral de ensaios terapêuticos, encerram a promessa de um futuro mais promissor para pacientes com fibrose pulmonar idiopática. Por exemplo, nós temos agora uma compreensão mais abrangente a respeito dos critérios diagnósticos e da história natural da doença. Vários estudos têm mostrado que a mensuração simples da fisiologia pulmonar ou troca gasosa pode ser usada para prever a sobrevida do paciente. Através da identificação de várias vias moleculares que têm papéis importantes na patogênese da fibrose pulmonar idiopática, os pesquisadores têm produzido uma lista crescente de possíveis novos alvos terapêuticos para a doença. Vários ensaios terapêuticos prospectivos e controlados têm sido realizados. Outros estão em andamento ou ainda estão em fase de planejamento. Estes esforços têm avançado nosso conhecimento atual sobre fibrose pulmonar idiopática e levantado novas questões importantes, assim como têm gerado o interesse e o impulso necessários para avançar terreno na luta contra esta doença desafiadora.

    Full Text Available La embolia pulmonar séptica es una enfermedad grave y poco frecuente que se caracteriza por presentar infiltrados pulmonares bilaterales asociados a un foco infeccioso extrapulmonar. Se relaciona principalmente a endocarditis derecha, tromboflebitis pelviana, accesos vasculares y menos frecuentemente a infecciones profundas como osteomielitis, artritis séptica o piomiositis. El Staphylococcus aureus meticilino-resistente adquirido en la comunidad (SAMR-AC es un patógeno emergente, con alta virulencia y de rápida propagación, que afecta a sujetos sin enfermedades previas relacionadas o factores de riesgo conocidos. Causa infecciones de piel y partes blandas y con menor frecuencia infecciones graves como fascitis necrotizante, artritis séptica, osteomielitis, piomiositis y neumonía necrotizante. Su epidemiología, patogenia y manifestaciones clínicas difieren de las causadas por el SAMR adquirido en el hospital. Presentamos el caso de un varón de 67 años con embolias pulmonares sépticas causadas por SAMR-AC con origen en una infección cutánea.Septic pulmonary embolism is a serious and rare illness characterized by pulmonary infiltrates associated with an extrapulmonary infectious focus. It is mainly related to right-sided endocarditis, pelvic thrombophlebitis, vascular access and less frequently to deep infections such as osteomyelitis, septic arthritis and pyomyositis. The community-acquired methicillin-resistant Staphylococcus aureus (MRSA is an emerging pathogen with high virulence and rapid spread involving subjects without previous related diseases or known risk factors. It causes infections of skin and soft tissue and less frequently other serious infections such as necrotizing fascitits, septic arthritis, osteomyelitis, pyomyositis and necrotizing pneumonia. Epidemiologically, pathogenesis and clinical manifestations differ from those caused by MRSA acquired in the hospital. We present the case of a 67 year-old male with septic
