    Full Text Available Liquoric fistula (LF is defined as the communication of the subarachnoid space with the external environment, which main complication is the development of infection in the central nervous system. We reported the case of a patient with non-traumatic eyelid liquoric fistula secondary to orbital meningocele (congenital lesion, which main clinical manifestation was unilateral eyelid edema. Her symptoms and clinical signs appeared in adulthood, which is uncommon. The patient received surgical treatment, with complete resolution of the eyelid swelling. In conclusion, eyelid cerebrospinal fluid (CSF fistula is a rare condition but with great potential deleterious to the patient. It should be considered in the differential diagnosis of unilateral eyelid edema, and surgical treatment is almost always mandatory.

    Anterior sacral meningoceles (ASM) in Marfan syndrome are rare. They may cause constipation, urinary frequency, dysmenorrhoea, and low back pain or numbness. This report describes bilateral ASM at the level of S1, S2 and S3 in a woman with Marfan syndrome who was admitted to the gynaecology department for evaluation of left lower abdominal pain. The magnetic resonance appearance of the meningoceles is discussed and compared with findings from transvaginal ultrasound and CT. As MRI offers excellent delineation of spinal and pelvic structures, it is the most useful technique available in establishing the diagnosis and planning the treatment of ASM. (orig.)

  11. Encephalocele development from a congenital meningocele: case report.

    A fetal MRI study obtained at 21 weeks' gestation revealed a suboccipital meningocele without hydrocephalus. One day after term birth, MRI demonstrated an acquired cerebellar encephalocele, and MRI obtained 5 months later showed progressive enlargement of the encephalocele, still without obvious hydrocephalus. The patient underwent an operation in which an external ventricular drain was placed, the grossly normal cerebellum was reduced into the posterior fossa without resection, and the dural defect was closed. The drain was weaned out over 5 days, and no ventriculoperitoneal shunt was placed. Postoperative MR images revealed normal cerebellum and no hydrocephalus. The patient is developmentally normal. Meningocele and encephalocele are embryologically distinct. An acquired encephalocele could develop from hydrocephalus (which was not present in this case), or secondary to the lower resistance to expansion into the dural defect of the meningocele relative to the resistance to expansion of the fetal skull. The cerebellar tissue was normal in this case, and was thus preserved. The developmental prognosis is excellent. To the authors' knowledge, this is the first reported case of this occurrence. It is important to differentiate between congenital and acquired encephalocele etiologies, because resection of the cerebellar tissue in an acquired encephalocele (as is routinely done in cases of congenital encephalocele) would be expected to result in neurological deficits.

    Myelo-meningoceles are part of congenital afflictions of the spinal column. They arise from the failure of the neural tube to fuse properly during early embryonic growth. The causes and sequalae are multiple and, therefore, require multiple disciplines, to handle them. This study assessed the role of inter-disciplinary approach in the management of myelo-meningoceles. From 1975 to 2007, the author repaired 20 midline lumbar and lumbo-sacral myelo-meningoceles; 5 in Jamaica and 15 in Nigeria. There were 11 males and 9 females. Their ages, at operation, ranged from 1 to 168 days. All had urine and faecal incontinence and severe paraparesis to paraplegia. Skeletal deformities were present in 16 cases. The operations were carried out under routine general anaesthesia and in prone position. All cases were followed-up for up to 60 months, apart from one who died 4 days at home after discharge. There were no deaths within the period of hospitalisation, usually about 14 days. Those followed-up have not made much improvement, though they were able to sit up without support and move around by shifting on their buttocks on the floor. We must continue to help these patients, but under the umbrella of specialised rehabilitation centres with the different specialists working together to make these patients attain a meaningful life and be useful to themselves and the society.

  13. Endoscopic endonasal repair of spontaneous sphenoid sinus lateral wall meningocele presenting with cerebrospinal fluid leak

    Full Text Available Spontaneous sphenoid sinus lateral wall meningoceles are rare lesions with an unknown etiology. Endoscopic endonasal technique is a considerable route in the treatment of this condition. The aim of this paper is to report the etiology, surgical technique, and outcome in a patient repaired via endoscopic endonasal approach. A 51-year-old male patient applied with rhinorrhea started three months ago after an upper respiratory infection. There were no history of trauma or sinus operation. Biochemical analysis of the fluid was positive for beta-2-transferrin. This asypthomatic patient had undergone for repairment of lateral sphenoid sinus meningocele with endoscopic endonasal transsphenoidal approach. After endoscopic endonasal meningocele closure procedure no complications occured and a quick recovery was observed. Endoscopic endonasal approach is an effective and safe treatment modality of spontaneous lateral sphenoid sinus meningoceles and efficient in anterior skull base reconstruction.

    2016-08-01

    Lumbo-costo-vertebral syndrome (LCVS) is a rare disorder in children that is characterized by hemivertebrae, congenital absence of ribs, meningocele, and hypoplasia of the truncal and abdominal wall presenting as a congenital lumbar hernia. An otherwise healthy 12-month-old girl was referred to the authors' hospital with soft swelling on her left middle back; scoliosis had been present since birth. Imaging revealed a thoracic meningocele, ectopia of the spleen suggesting lumbar hernia, multiple anomalies of the thoracic vertebral columns, and defects of the ribs; thus, LCVS was diagnosed. Surgical observation revealed that the meningocele was firmly anchored to part of the diaphragm, which created stretching tension in the meningocele continuously with exhalation. Once detached, the meningocele shrank spontaneously and never developed again after cauterization. In this case, continuous or pulsatile pressure in the presence of a vertebral defect was thus considered to be an important factor for formation of the thoracic meningocele.

    Full Text Available BACKGROUND: Intrathoracic meningocele is a rare pathology, almost always associated with neurofibromatosis type I and with a few cases related in the literature. In the majority of cases cysts are small or asymptomatic, and the surgery is indicated when big or symptomatic cysts are present. We report a case of giant intrathoracic cysts surgically extirpated through out thoracotomy. CASE: A 59-year-old male with familiar Von Recklinghausen's disease which developed thoracic radicular pain after a fall. On examination he presented some difficulty in walking fast and dyspneia on small efforts. The chest plain x-ray showed the presence of 3 huge left side intrathoracic cysts (10 to 15cm. The patient was submitted to a surgical treatment and complete extirpation of the cysts was performed through a left side thoracotomy. During the surgery a fourth smaller cyst was detected and also extirpated. Evolution was uneventful and the patient remains well in these last 12 years. This finding of intrathoracic cysts related to neurofibromatosis type I is rare and is probably unique in the literature the presence of 4 huge cysts in one side of the thorax.Meningocele intratorácica é patologia rara e, quando presente, está quase sempre associada a neurofibromatose tipo I. Há poucos casos descritos na literatura e em sua maioria destes são de cistos pequenos ou assintomáticos, sendo a cirurgia indicada quando são grandes ou sintomáticos. Relatamos o caso de um homem de 59 anos com a doença de Von Recklinghausen familiar, com cistos gigantes extirpados cirurgicamente através de toracotomia.

    Epithelioid hemangioendothelioma (EHE) is a rare vascular soft-tissue tumour of intermediate malignancy. Neurofibromatosis type I (NF-1) is a genetic syndrome associated with soft tissue sarcoma and higher risk of developing neoplasia. Lateral meningoceles are uncommon entities, being mostly associated with NF-1. We report a case of a 31-year-old woman, with NF-1 and past history of right thalamic/peduncular astrocytoma WHO grade II, admitted to the Neurosurgery Department in December 2003 due to severe low back pain, irradiating to the left leg without a radicular pattern. Thoraco-lumbar magnetic resonance imaging (MRI) showed a large left posterior paravertebral expansive lesion, bilateral and multiple thoraco-lumbar lateral meningoceles and dural ectasias with scalloping of the vertebral bodies. Biopsy of the paravertebral mass lesion disclosed EHE. We present this case because of the novel association between NF-1 and EHE, and the unusual aggressiveness of the neoplasia. Additionally, we highlight the co-existence of bilateral and multiple lateral meningoceles. (orig.)

    2018-01-01

    Petrous apex meningocele (PAM) is an uncommon cystic lesion involving the petrous apex. The underlying cause of PAM may be related to chronic elevated intracranial pressure. The aim of the study was to explore the relationship between PAM and meningioma and between PAM and other intracranial hypertension findings. Two hundred seventy-eight consecutive patients with meningiomas were retrospectively studied. Fifty age- and gender-matched controls were also enrolled in this study. The incidence of PAM, empty sella, tortuosity of the optic nerve, and hydrops of optic nerve sheath was evaluated. The maximum width, area, volume of each PAM, or Meckel's cave and volume of meningioma were measured in controls and patients, separately. One hundred fifty-nine (57.19%) patients were detected with coexistent PAMs. One hundred twenty-five patients had bilateral PAMs, 34 had unilateral lesions, and the remaining 119 did not have PAM. Two subjects (4/50) had unilateral PAMs in normal controls. The maximum width, area, volume of PAM, or Meckel's cave were significantly larger in the patients with bilateral PAM group than those in the unilateral PAM group, in the group without PAM, and those in control group (p = 0.000). The volume of meningioma was positively correlated with the PAM volume (r = 0.48). There was a positive correlation for the incidence between PAM and (1) empty sella (r = 0.901) and (2) tortuosity of the optic nerves and hydrops of the optic sheath (r = 0.825). Coexistence of PAMs with meningiomas is not rare in incidence, and it suggests a potential role for chronically elevated intracranial pressure and disturbance of CSF circulation in their pathophysiology.

    Myelography and CT myelography (CMT) were reviewed in 18 cases of birth palsy with clinically suspected avulsion injury. Root-somatosensory evoked potential (root-SEP) was also reviewed for myelographic evaluation of the nerve root avolusion in birth palsy. Root-SEP is not induced in case of avulsed nerve roots, but is induced in case of both normal and incompletely avulsed roots. Myelography demonstrated 58 abnormal nerve roots in 18 cases (19 limbs); 45 (78%) complete and 13 (22%) incomplete nerve root avulsions. Each of complete and incomplete avulsions was defined as total absence and partial presence of rootlets on myelography, respectively. Traumatic meningoceles were detected at 46 roots (79%) on myelography and/or CTM; 35 roots on myelography and 45 roots on CTM. CTM could not detect only a very small meningocele at one root. At 11 roots CTM was superior to myelography in delineating a meningocele because CTM is sensitive to a poorly enhanced meningocele. CTM, however, could not diagnose nerve root avulsions so accurately as myelography, since myelography detected 12 (7 completely and 5 incompletely) avulsed roots without meningocele, whereas CTM could not delineate the nerve roots clearly. Thus, myelography is indispensable to evaluate nerve root avulsions without meningocele. Root-SEP was examined in 9 patients who underwent branchial plexus exploration. SEP was negative at 22/25 roots with complete avulsion and was positive at 7/7 roots with myelographically incomplete avulsion, regardless of presence or absence of any traumatic meningocele. Myelography and root-SEP correlated well at 29 (92%) out of 32 roots in evaluating complete and incomplete avulsion injuries. Myelography and root-SEP were not considered in 3 roots. Though myelography demonstrated complete avulsions with traumatic meningocele, SEP was positive in these three roots, which were interpreted as partially avulsed roots. (J.P.N.).

    2006-06-01

    We describe the clinical presentation of a boy with Peters anomaly and a cataract of the left eye in association with multiple midline defects. His extraocular developmental abnormalities include cleft lip and palate, cardiac anomalies, an atretic cranial meningocele, as well as malformation of the left ear with chronic otitis media. Genetic analysis revealed a balanced paracentric inversion of chromosome 4, inv(4)(q12q13.3), also present in his asymptomatic father and siblings. His normal stature and cognitive development distinguish this case from the Peters Plus syndrome. The presence of a cranial meningocele represents a new association with Peters anomaly.

This article provides a comprehensive review of syndromes, disorders, and maternal risk factors associated with NTDs, such as Currarino syndrome, sacral defect with anterior meningocele, Jarcho-Levin syndrome (spondylo-costal dysostosis, lateral meningocele syndrome, neurofibromatosis type I, Marfan syndrome, and hyperthermia. The recurrence risk and the preventive effect of maternal folic acid intake in NTDs associated with syndromes, disorders, and maternal risk factors may be different from those of non-syndromic multifactorial NTDs. Perinatal identification of NTDs should alert one to the syndromes, disorders, and maternal risk factors associated with NTDs, and prompt a thorough etiologic investigation and genetic counseling.

    Spinal neural foraminal widening is usually caused by benign lesions, most commonly neurofibromas. Rare lesions can also cause spinal neural foraminal widening. Computed tomography and/or MRI are the modalities of choice for studying the spinal foraminal widening. The present pictorial review describes six rare lesions, namely a lateral thoracic meningocele, a malignant fibrous histiocytoma, a tuberculous abscess, an osteoblastoma, a chondrosarcoma and a malignant tumour of the lung which caused spinal neural foraminal widening.

    Masses of the lateral skull are not uncommon and include lipomas and epidermoids. However, meningoceles of the lateral skull are very rare and are often misdiagnosed. Even rarer are atretic encephaloceles of this region. We report a newborn with a right atretic encephalocele of the asterion. Lesions of the anterolateral and posterolateral fontanelles should include lateral cephaloceles/encephaloceles in the differential diagnosis. The literature and embryology of these rare entities are discussed. © Springer-Verlag 2010

    Bony erosions of the lumbosacral spinal canal can be caused by tumors, meningoceles, meningeal or arachnoidal cysts and perineural cysts. The bony abnormalities may be visible on plain roentgenograms of the spine and on computed tomograms. Computerized tomography, particularly in conjunction with iohexol myelography, provides the most definitive anatomical study. Meningeal cysts are common in neurofibromatosis and are an uncommon accompaniment of ankylosing spondylitis. Both conditions can be differentiated by computerized tomography. 10 refs.; 4 figs

    1989-01-01

    Ten cases of brachial plexus injury were subjected to magnetic resonance (MR) to demonstrate the roots, trunks, divisions or cord abnormalities. Both normal and abnormal brachial plexuses were imaged in sagittal, axial, coronal and axial oblique planes. Myelography, using water soluble contrast agents, was performed in seven cases. MR demonstrated one traumatic meningocele, one extradural cerebrospinal fluid (CSF) collection, trunk and/or root neuromas in four, focal root fibrosis in two and diffuse fibrosis in the remaining two cases. Results of MR were confirmed at surgery in four cases with neuromas, while myelography was normal in two and was not carried out in the remaining two. In two cases, where MR demonstrated diffuse fibrosis of the brachial plexus, myelography showed C7 and T1 traumatic meningocele in one and was normal in the other. Both these patients showed excellent clinical and electrophysiological correlation with MR findings and in one of them surgical confirmation was also obtained. In the other two cases with focal nerve root fibrosis, myelography was normal in one and showed a traumatic meningocele in another. Operative findings in these cases confirmed focal root fibrosis but no root avulsion was observed although seen on one myelogram. Focal fibrosis, however, was noted at operation in more roots than was observed with MR. Initial experience suggests that MR may be the diagnostic procedure of choice for complete evaluation of brachial plexus injuries. (orig.)

    The Currarino syndrome is a rare triad that is a combination of a presacral mass, a congenital sacral bony abnormality and an anorectal malformation. We present 4 children with complete Currarino triad who were diagnosed using MRI. Our aim was to report the neurosurgical management of Currarino syndrome in children. All of the patients had chronic constipation and pain in the lumbosacral region. In the plain radiograph, 3 patients had a sacral scimitar-shaped bony abnormality, and 1 patient had total sacral agenesis. There was a narrow anal canal or narrow ventrally displaced anus in all patients. Their anorectal malformations were characterized as anal stenoses (4 patients), associated with Hirschsprung's disease in 2 cases. In 3 patients, MRI showed tethered cord syndrome in addition to the presacral mass. There was hydrocephalus in 1 patient. Anal stenosis was treated by anal dilatation. In 2 patients, rectal biopsy and temporary colostomy (2 patients) had been performed previously due to Hirschsprung's disease. We performed a posterior procedure via lumbar and sacral partial laminectomy-laminoplasty and transdural ligation of the neck of the meningocele for anterior sacral meningoceles, or alternatively, tumor excision for other types of presacral lesions. Histopathologically, 3 were cases of anterior sacral meningoceles and 1 was a teratoma. One of them also had a spinal abscess. He required reoperation (twice) and appeared at the time to have improved with medical therapy. All patients improved and stabilized. There were no additional neurological deficits and no recurrence of the presacral mass over the follow-up period (6 years, on average). The family pedigree did not reveal any familial transmission pattern. In cases of Currarino triad, MRI can allow the characterization of the presacral masses. If it is an anterior sacral meningocele or a solid tumor without severe anorectal malformation, it can be managed with posterior lumbar and sacral procedures

    The basic abnormality of neurofibromatosis consists not only of a maldevelopment of the neuroectoderm but also of the mesoderm. Therefore any organ or system of the body may be involved. Following a short clinical review of the central (acoustic) and peripheral type the well known and the more unusual radiographic findings are summarized. They include cranial and intracranial manifestations (orbitosphenoid dysplasia, bone defects of the skull, acoustic neuroma, glioma of the optic nerve and chiasm, meningioma), spinal lesions (scoliosis, vetebral scalloping, meningocele, neuroma, ependymoma), skeletal abnormalities (pseudarthrosis), cardiovascular manifestations, pulmonary fibrosis, tumors of the gastrointestinal and urinary tract and different endocrinopathies. Some of the roentgeologic symptoms are very characteristic and allow definitive diagnosis.

    Full Text Available Abstract Introduction Neuroendocrine tumors are a rare but diverse group of malignancies that arise in a wide range of organ systems, including the mediastinum. Differential diagnosis includes other masses arising in the middle mediastinum such as lymphoma, pericardial, bronchogenic and enteric cysts, metastatic tumors, xanthogranuloma, systemic granuloma, diaphragmatic hernia, meningocele and paravertebral abscess. Case presentation We present a case of 42-year-old Caucasian man with a neuroendocrine tumor of the middle-posterior mediastinum and liver metastases, which resembled a lymphoma on magnetic resonance imaging. Conclusion The differential diagnosis in patients with mediastinal masses and liver lesions should include neuroendocrine tumor.

    Orbital meningoceles and encephaloceles are rare extracranial extensions of the brain and meninges with or without direct communication between the central nervous system and the abnormal mass. We reported a rare case of large fetal orbital encephalocele; the diagnosis was suspected initially by prenatal ultrasound and confirmed by postnatal MRI and CT scans. The differential diagnosis of an intrauterine fetal cystic orbital mass includes orbital teratoma, epidermoid inclusion cysts, hemangioma or lymphangioma, congenital cystic eye, dacryocystocele, and orbital cephalocele.

    Full Text Available A 22-year-old female, a known case of neurofibromatosis 1 (NF1, presented with a congenital swelling in the left occipital region. She had developed recent onset dysphagia and localized occipital headache. Neuroradiology revealed a left occipital meningoencephalocele and a left parapharyngeal meningocele. This was associated with ventriculomegaly. She was advised on cranioplasty along with duraplasty which she denied. She agreed to a lumbar-peritoneal shunt. She described a dramatic improvement in her symptoms following the lumbar-peritoneal shunt. Occipital dysplasias, though uncommon, have been reported in the literature. We review this case and its management and discuss relevant literature on occipital dysplasias in NF1.

    The authors reviewed the teaching files of Temple University Hospital and Children's Hospital of Philadelphia and selected the best representative cases of various lesions of the sacrum. They selected the following lesions: metastasis, chondrosarcoma, chrodoma, plasmacytoma, giant cell tumor, osteogenic sarcoma, Ewing sarcoma, neuroblastoma, neurofibrosarcoma, hemangiopericytoma, osteoblastoma, ossifying fibroma, eosinophilic granuloma, aneurysmal bone cyst, sacrococcygeal teratoma, anterior meningocele, endodermal sinus tumor, and stress fracture. The authors illustrate, for each lesion, the likely age range, sights of predilection, likelihood of occurrence in the sacrum, and radiographic findings helpful in limiting the differential diagnosis. They demonstrate the value of bone scintigraphy in detecting, and CT in confirming, stress fractures of the sacrum

    One hundred fifty children with congenital malformations of the spine were studied with MR imaging, US, and water-soluble myelography with CT. The malformations encountered included myelomeningoceles and Chiari II malformations, diastematomyelia, hydromyelia, arachnoid cyst, dermal sinus and dermoid, spinal lipomas and teratomas, tight filum terminale, anterior sacral meningoceles, lipomyelomeningoceles, myelocystocele, and severe scoliosis. MR imaging was the most effective modality in delineating these abnormalities. At times, real-time US and water-soluble CT myelography were required as adjuncts to MR imaging in delineating subtle spinal cord tethering, arachnoid cyst, diastematomyelia, and severe scoliosis

    1986-01-01

    Fifteen patients with neurofibromatosis affecting the spine and paraspinal regions were examined by MR imaging performed using spin-echo pulsing sequences. Neurofibromas had slightly greater signal intensity than muscle on T1-weighted images and markedly increased signal intensity on T2-weighted images. Central areas of decreased signal intensity of T2-weighted images corresponded pathologically to relatively fibrous components of the neurofibromas. The lack of this ''double-density'' appearance was useful in excluding the diagnosis of neurofibroma in one patient with lateral meningoceles and one patient with a neurofibrosarcoma. MR imaging also demonstrated extradural cord compression in three patients and cystic, intramedullary cord tumors in two patients

    Full Text Available The dorsal cutaneous appendage or the so called human tail is a rare congenital anomaly protruding from the lumbo-sacro-coccygeal area. These caudal appendages are divided into true-tails and pseudo-tails. We report here two cases of congenital pseudo-tail with underlying spina bifida and lipo-meningocele. In this article we seek to emphasize that, as the skin and nervous systems are intimately linked by their similar ectodermal origin, a dorsal appendage may be regarded as a cutaneous marker of the underlying spinal dysraphism.

    2018-01-01

    Local flaps exhibit excellent color matching that no other type of flap can compete with. Moreover, surgery using a local flap is easier and faster than surgery using a distant or free flap. However, local flaps can be much more difficult to design. We designed 2 templates to plan a V-Y rotation advancement flap. The template for a unilateral V-Y rotation advancement flap was used on the face (n=5), anterior tibia (n=1), posterior axilla (n=1), ischium (n=1), and trochanter (n=2). The template for a bilateral flap was used on the sacrum (n=8), arm (n=1), and anterior tibia (n=1). The causes of the defects were meningocele (n=3), a decubitus ulcer (n=5), pilonidal sinus (n=3), and skin tumor excision (n=10). The meningocele patients were younger than 8 days. The mean age of the adult patients was 50.4 years (range, 19-80 years). All the donor areas of the flaps were closed primarily. None of the patients experienced wound dehiscence or partial/total flap necrosis. The templates guided surgeons regarding the length and the placement of the incision for a V-Y rotation advancement flap according to the size of the wound. In addition, they could be used for the training of residents.

    Joubert et al. first reported a familial syndrome which showed episodic tachypena, abnormal eye movement, mental and motor retardation. Since then eighteen cases have been reported in the world. In this paper, we reported a male baby with Joubert syndrome who was observed since the newborn period. He showed episodic tachypnea (respiratory rate over 100/min), apnea, severe mental and motor retardation, no normal eye movements, occipital meningocele, high arched palate and poor sucking. CT scan revealed vermian agenesis, hypoplasia and deformity of brainstem, enlarged fourth ventricle and cisterna magna. EEG showed episodic discharges. Laboratory test investigations including amino acids, lactate, pyruvate, ammonia, chromosomal analysis, IVP and renogram showed no abnormal findings. He showed poor development and at eleventh month of age he died at home because of respiratory arrest. Similar syndromes were reported by Koya et al., Dekaban, Gardner et al., D'Agostino et al. and Friede. They reported syndromes consisting of abnormal respiration, abnormal eye movements, mental and motor retardation, occipital meningocele, retinal degeneration and polycystik kidney. Some causative events may have occurred at 6 to 7 weeks of gestation affecting central nervous system as well as other organs. (author)

Its underlying cause is not known but teratogenic environmental agents are suspected. However, nutritional deficiency, as in spina bifida, cannot be excluded. Methods This study reports 21 cases of meningocele (without brain tissue in the lesion and encephalomeningocele (with brain tissue that were admitted to our hospital for surgical corrections in the period of ten years, from 1990 to 1999. Clinicopathological findings, as well as occupations of family members and prenatal exposures to infectious agents or chemicals were reviewed and analyzed. Results The most commonly involved area was the frontoethmoidal region, found in 20 cases. The combined pattern between nasoethmoidal and nasoorbital defects was found most frequently (11 from 21 cases and had more associated abnormalities. Encephalomeningocele had more related abnormalities than meningocele with proportions of 0.6 and 0.3, respectively. Conclusions Here, we confirmed that genetic defects are not likely to be the single primary cause of this malformation. However, we could not draw any conclusions on etiologic agents. We suggest that case control studies and further investigation on the role of nutritional deficiencies, especially folic acid, in the pathogenesis of encephalomeningocele are necessary to clarify the underlying mechanisms.

    The diagnosis and management of pediatric cerebrospinal fluid (CSF) leak and encephalocele are challenging. The current study aimed to identify patient characteristics, review operative techniques, and evaluate the efficacy and safety of endoscopic endonasal repair in a pediatric population. We retrospectively reviewed the records of pediatric patients who underwent transnasal endoscopic repair of CSF leak with or without a meningocele or an encephalocele at Beijing Tongren Hospital, Capital Medical University, between July 2003 and May 2014. All patients had preoperative radiological evaluations and underwent endoscopic endonasal repair of their skull base defects. Altogether, 23 children (mean age 7.0 years) underwent the procedures. Sixteen cases were congenital, and 7 patients had trauma history. The herniations or defects included meningoencephaloceles in 15 cases, meningoceles in 4 cases, and CSF leak in 4 cases (2 patients had bilateral leaks). The leak or herniation sites were ethmoid roof in 10 patients (one was bilateral), cribriform plate in 5, lateral to the foramen cecum in 3, posterior wall of the frontal sinus in 1, sphenoid sinus in 2, lateral recess of the sphenoid sinus in 1, and sella turcica base in 2. All subjects had favorable clinical outcomes without recurrence during a follow-up of 6-123 months (mean 61.1 months). The endoscopic endonasal approach was the preferred method for repairing CSF leaks with or without an encephalocele in pediatric patients. Compared to traditional operations, this endoscopic procedure is minimally invasive, efficient, and safe.

    Full Text Available Local flaps exhibit excellent color matching that no other type of flap can compete with. Moreover, surgery using a local flap is easier and faster than surgery using a distant or free flap. However, local flaps can be much more difficult to design. We designed 2 templates to plan a V-Y rotation advancement flap. The template for a unilateral V-Y rotation advancement flap was used on the face (n=5, anterior tibia (n=1, posterior axilla (n=1, ischium (n=1, and trochanter (n=2. The template for a bilateral flap was used on the sacrum (n=8, arm (n=1, and anterior tibia (n=1. The causes of the defects were meningocele (n=3, a decubitus ulcer (n=5, pilonidal sinus (n=3, and skin tumor excision (n=10. The meningocele patients were younger than 8 days. The mean age of the adult patients was 50.4 years (range, 19–80 years. All the donor areas of the flaps were closed primarily. None of the patients experienced wound dehiscence or partial/total flap necrosis. The templates guided surgeons regarding the length and the placement of the incision for a V-Y rotation advancement flap according to the size of the wound. In addition, they could be used for the training of residents.

    Joubert et al. first reported a familial syndrome which showed episodic tachypena, abnormal eye movement, mental and motor retardation. Since then eighteen cases have been reported in the world. In this paper, we reported a male baby with Joubert syndrome who was observed since the newborn period. He showed episodic tachypnea (respiratory rate over 100/min), apnea, severe mental and motor retardation, no normal eye movements, occipital meningocele, high arched palate and poor sucking. CT scan revealed vermian agenesis, hypoplasia and deformity of brainstem, enlarged fourth ventricle and cisterna magna. EEG showed episodic discharges. Laboratory test investigations including amino acids, lactate, pyruvate, ammonia, chromosomal analysis, IVP and renogram showed no abnormal findings. He showed poor development and at eleventh month of age he died at home because of respiratory arrest. Similar syndromes were reported by Koya et al., Dekaban, Gardner et al., D'Agostino et al. and Friede. They reported syndromes consisting of abnormal respiration, abnormal eye movements, mental and motor retardation, occipital meningocele, retinal degeneration and polycystic kidney. Some causative events may have occurred at 6 to 7 weeks of gestation affecting central nervous system as well as other organs.

    Introduction. Breast cancer is the most common malignancy of women in the world Western. It is rare below 30 years. Marfan syndrome (MS) is an entity clinically characterized by cardiovascular, ocular and skeletal genetic base. Its prevalence is estimated at 4-6 per 100,000 births. In the literature there are few reports of cancers diagnosed in association with SM, and after a thorough review, we found only two communications association with malformations such as dural sac meningocele. Objective. The aim of this study was to review the literature from communication A case report of a patient with SM in which the age of 24 he diagnosed with breast cancer and a previous sacral meningocele. Case. Female patient 24 years old, with SM, who consulted a tumor of right breast. Was studied with mammography and cytological puncture were positive for malignancy. Local treatment consisted of modified radical mastectomy and chest wall radiotherapy. The pathology corresponded to ductal carcinoma Infiltrating (CDI) NOS 27mm diameter greater final histologic grade II carcinoma in situ solid and cribriform intermediate grade without necrosis greater than 30%; 10 axillary lymph resected, all free of metastases. The dosage of hormone receptors was frankly positive for both estrogen and progesterone. In sum CDI NOS stage IIA. the chest radiograph and bone scan showed no abnormalities and abdominal ultrasound He requested postoperatively revealed an abdominopelvic image 13 x 16 cm. positron abdomen and pelvis confirmed a predominantly cystic mass in the pelvis and abdomen lower. Exploratory laparotomy revealed that the tumor corresponded to a meningocele before and proceeded to peritoneal cyst resection and closure of the sacral gap. At the time of writing, the patient is free and without neurological deficit disease, low adjuvant Tamoxifen for 3 years. Conclusions. The SM as breast cancer in younger women is uncommon. Few cancers have been reported in association with SM. Some of

    We report two cases of fetal inner ear abnormalities diagnosed by MRI. Cerebral MRI was performed on two fetuses, at 32 and 30 weeks gestation, following US that demonstrated multiple malformations suggestive of CHARGE syndrome in one fetus and ventriculomegaly and poor visibility of the posterior fossa in the other. MRI revealed vestibular hypoplasia and agenesis of the semicircular canals in one fetus and cystic cochleas, partial vermian agenesis and an occipital meningocele in the second fetus. Both pregnancies were terminated and there was good correlation between fetal MRI, ex utero CT and fetopathological findings. The inner ears should be carefully examined when performing fetal cerebral MRI because abnormalities of the inner ear may be associated with cerebral anomalies. (orig.)

    The basic abnormality of neurofibromatosis consists not only of a maldevelopment of the neuroectoderm but also of the mesoderm. Therefore any organ or system of the body may be involved. Following a short clinical review of the central (acoustic) and peripheral type the well known and the more unusual radiographic findings are summarized. They include cranial and intracranial manifestations (orbitosphenoid dysplasia, bone defects of the skull, acoustic neuroma, glioma of the optic nerve and chiasm, meningioma), spinal lesions (scoliosis, vetebral scalloping, meningocele, neuroma, ependymoma), skeletal abnormalities (pseudarthrosis), cardiovascular manifestations, pulmonary fibrosis, tumors of the gastrointestinal and urinary tract and different endocrinopathies. Some of the roentgeologic symptoms are very characteristic and allow definitive diagnosis. (orig.)

    The use of myelography in obstetric palsies of brachial plexus is aimed at diagnosing root avulsion.This kind of lesion appears as the disappearance of the slightly-transparent nerve roots which might be combined either with pseudo-meningocele or with deformation of radicular pouch. This study 69 operated patients who had previously undergone myelography have been considered. In 74.2% of cases mylographic findings were confirmed at surgery.False positives and false negatives were 9.7% and 3.2%, respectively. Uncorrect diagnoses were made in 12.9% of cases, because of misread lesions and uncorrect evaluation of their location, usually at the cervicol-dorsal junction.No side-effects were observed. Myelography appears thus to be extremely useful for both the preoperative evaluation and the choice of surgery in newborn children with obstetric palsy of the brachial plexus

    The authors describe an interesting case of a hitherto asymptomatic occult spinal defect with a congenital sacral dermal sinus which proved to be the entry point for bacterial meningitis in an otherwise healthy 9-year-old female child. The patient presented with fever and neck stiffness, and a dermal sinus in the lumbosacral region was identified on examination. Cerebrospinal fluid analysis confirmed bacterial meningitis and a spinal magnetic resonance imaging scan revealed a dermal sinus tract with an anterior spinal meningocele, caudal regression syndrome, and a tethered spinal cord. In addition to administration of intravenous antimicrobial agents, surgical exploration of the sacral dermal sinus tract was performed and an anterior sacral pyocele was drained. The pyocele cavity was disconnected from the thecal sac, and the thickened and fatty filum terminale was sectioned. Although congenital sacral dermal sinus manifesting as bacterial meningitis is known, the occurrence of an anterior sacral pyocele has not yet been described in children.

    Patients with cutaneous markers in the lumbo-sacral region as well as infants with bladder and bowel dysfunction, orthopedic anomalies and progressive neurological dysfunction are at risk for spinal dysraphism and tethered cord. Three types of spinal dysraphism can be distinguished: Type I - open spinal dysraphisms with a non-skin covered back mass; type II - closed spinal dysraphisms with a skin covered back mass; type III - occult spinal dysraphisms without a back mass. All spinal dysraphisms can be associated with a tethered cord, characterized by a low position of the conus medullaris below L3. Type I dysraphisms are meningomyeloceles and myeloceles, which are associated with CHIARI-II malformations characterized by the low position of the cerebellar vermis within the foramen magnum. Type II dysraphisms are lipomyeloceles, lipomyelomeningoceles, posterior meningoceles and myelocystoceles. Lipomeningoceles and lipomyelomeningoceles are characterized by a subcutaneous echogenic mass which communicates with the spinal canal and may cause tethered cord. Posterior meningoceles are, dorsal cystic space occupying lesions without internal neural tissue. Myelocystoceles are characterized by a cystic dorsal mass which communicates with a dilated central canal characteristic of syringo-hydromyelia. Type III dysraphisms without a back mass are frequently associated with cutaneous markers in the lumbo-sacral region. Sonographically dermal sinus tracts, diastematomyelia, tight filum and lipoma of the filum terminale and the caudal regression syndrome have to be distinguished. Dermal sinuses are characterized by an echogenic tract from the skin to the spinal canal, often associated with a spinal dermoid. Diastematomyelia is characterized by a complete or partial duplication of the spinal cord which can only be shown on axial images. Tight filum terminale or lipoma of the filum terminale is characterized by a thick echogenic filum with a diameter of more than 2 mm, and a conus

    The aim of this study was to evaluate sequences that are established at lower magnetic field strengths for lumbar spine imaging at 7 Tesla (7 T) MR imaging. The lumbar spine of five healthy volunteers and a patient with spina bifida and meningocele were evaluated at 7 T. The examination included a T2-TSE (turbo spin echo), a 3D-DESS (double-echo steady-state sequence), a 3D-CISS (constructive interference in steady-state sequence), and a 3D-VIBE (volumetric interpolated breath hold examination) sequence. Imaging quality was evaluated by two raters on a three-level scale. The assessment included visualization of intraforaminal structures, the cauda equina, facet joints, and any abnormalities. Contrast ratios for intervertebral discs/vertebral bodies, vertebral bodies/cerebrospinal fluid (CSF) and CSF/spinal cord were calculated. The 3D-VIBE sequence provided best differentiation between intraforaminal structures. Visualization of the facet joints was reliable with VIBE, DESS, and CISS. Individual nerve roots of the cauda equina could only be delineated with the 3D-CISS sequence. CISS and DESS provided good contrast between vertebral bodies and intervertebral discs. Contrast between CSF and vertebral bodies was most pronounced for the T2-TSE sequence. Sufficient contrast between CSF and the spinal cord was only achieved with the T2-TSE sequence. VIBE and DESS sequences demonstrated best the bony malformations. Visualization of the meningocele was only possible with the 3D-CISS sequence. At 7 T most structures of the lumbar spine were visualized with a combination of sequences. At present, imaging quality is not superior to 1.5 T or 3 T, precluding routine clinical use.

    The spinal anomaly designated dorsal dysraphism with lipoma (lipomyeloschisis) consists of skin-covered, focal spina bifida; focal partial clefting of the dorsal half of the spinal cord; continuity of the dorsal cleft with the central canal of the cord above (and occasionally below) the cleft; deficiency of the dura underlying the spina bifida; deep extension of subcutaneous lipoma through the spina bifida and the dural deficiency to insert directly into the cleft on the dorsal half of the cord; variable cephalic extension of lipoma into the contiguous central canal of the cord; and variable ballooning of the subarachnoid space to form an associated meningocele. The variable individual expressions of the anomaly are best understood by reference to their archetypal concept. Careful analysis of radiographic and surgical findings in human lipomyeloschisis and correlation with an animal model of lipomyeloschisis indicate that plain spine radiographs and high-resolution metrizamide computed tomographic myelography successfully delineate the precise anatomic derangements associated with lipomyeloschisis and provide the proper basis for planning surgical therapy of this condition.

    For operative treatment of urinary incontinence after TUR of the prostate, radical prostatectomy and meningocele operation the silicongel prothesis described by Kaufman was implanted. By compression of the bulbus urethrae a sealing effect was achieved. The pressure of the detrusor opens the urethra enough to enable urination. Seven patients were operated. The results directly after the operations were: three very good, two good and two bad. We achieved very good results by implantation of the prothesis "large" -in the case of the two bad operative results we used the "medium" size prothesis. By filling these protheses with 5 ml liquid they proved to be leaky. One of these was operatively removed and replaced by the size "large". This patient later developed a urethra stricture in the implantation region with overflow bladder after having been continent. By internal urethrotomy this condition was restored; except for minor dripping after miction the patient was continent. The prothesis of a direct postoperative continent patient had to be filled. This led to and infection with the development of fistula. The prothesis had to be removed. A further patient who sat on a hard object developed a lesion of the prothesis with resulting incontinence. At least six months after the operations four patients remained continent and three incontinent.

    Spinal and spinal cord malformations are collectively named spinal dysraphisms. They arise from defects occurring in the early embryological stages of gastrulation (weeks 2-3), primary neurulation (weeks 3-4), and secondary neurulation (weeks 5-6). Spinal dysraphisms are categorized into open spinal dysraphisms (OSDs), in which there is exposure of abnormal nervous tissues through a skin defect, and closed spinal dysraphisms (CSD), in which there is a continuous skin coverage to the underlying malformation. Open spinal dysraphisms basically include myelomeningocele and other rare abnormalities such as myelocele and hemimyelo(meningo)cele. Closed spinal dysraphisms are further categorized based on the association with low-back subcutaneous masses. Closed spinal dysraphisms with mass are represented by lipomyelocele, lipomyelomeningocele, meningocele, and myelocystocele. Closed spinal dysraphisms without mass comprise simple dysraphic states (tight filum terminale, filar and intradural lipomas, persistent terminal ventricle, and dermal sinuses) and complex dysraphic states. The latter category further comprises defects of midline notochordal integration (basically represented by diastematomyelia) and defects of segmental notochordal formation (represented by caudal agenesis and spinal segmental dysgenesis). Magnetic resonance imaging (MRI) is the preferred modality for imaging these complex abnormalities. The use of the aforementioned classification scheme is greatly helpful to make the diagnosis.

    Full Text Available Reports focusing on biomedical principlism and the role of anaesthesiologists in palliative care are rare. We present the case of a newborn with multiple craniofacial anomalies and a diagnosis of ADAM “sequence,” in which surgical removal of placental adhesions to the dura mater and the correction of meningocele was not indicated due to the very short life expectancy. After 48 hours, the odor from the placenta indicted a necrotic process, which prevented the parents from being close to the child and increased his isolation. Urgent surgery was performed, after which the newborn was transported to the ICU and intubated under controlled mechanical ventilation. The patient died a week later. The principles of beneficence, nonmaleficence, justice, and respect for autonomy are simultaneously an inspiratory and regulatory framework for clinical practice. Although only necessary procedures are defended, which suggests a position contrary to invasive interventions at the end of life, sometimes they are the best palliative measures that can be taken in cases like the one described here.

Urgent surgery was performed, after which the newborn was transported to the ICU and intubated under controlled mechanical ventilation. The patient died a week later. The principles of beneficence, nonmaleficence, justice, and respect for autonomy are simultaneously an inspiratory and regulatory framework for clinical practice. Although only necessary procedures are defended, which suggests a position contrary to invasive interventions at the end of life, sometimes they are the best palliative measures that can be taken in cases like the one described here.

    Manuel Díaz Álvarez

    Full Text Available La malformación del cordón espinal hendido es una forma rara de disrafia espinal oculta, se reporta que representa el 3 % de los disrafismos ocultos. El mayor porcentaje de ellos es de localización lumbar. En la literatura cubana solo tenemos referencia de 2 pacientes publicados, una adulta y otro caso pediátrico. Se reporta un recién nacido remitido a nuestro centro por presentar meningocele occipital. Se detecta la presencia de una fosita en región sacro-coccígea, hipotonía muscular en miembro inferior derecho, pie varo con poca movilización del miembro, e incontinencia de esfínter vesical y anal. Los estudios de imagen demuestran la presencia de 2 hemimédulas a nivel lumbar, por lo que se confirma que el recién nacido presenta un síndrome de malformación del cordón espinal hendido, una entidad poco común. Presenta, además, la particularidad de haber sido diagnosticada en el período neonatal por exhibir desde su nacimiento manifestaciones clínicas, como consecuencia de esta entidad, aspecto también relevante, pues, habitualmente, la afección expresa la sintomatología más tarde en la vida, o se mantiene asintomática.

    Full Text Available Cerebrospinal fluid (CSF leak occurs due to a defect in the dura and skull base. Trauma remains the most common cause of CSF leak; however, a significant number of cases are iatrogenic, and result from a complication of functional endoscopic sinus surgery (FESS. Early diagnosis of CSF leak is of paramount importance to prevent life-threatening complications such as brain abscess and meningitis. Imaging plays a crucial role in the detection and characterization of CSF leaks. Three-dimensional, isotropic, high resolution computed tomography (HRCT accurately detects the site and size of the bony defect. CT cisternography, though invasive, helps accurately identify the site of CSF leak, especially in the presence of multiple bony defects. Magnetic resonance imaging (MRI accurately detects CSF leaks and associated complications such as the encephaloceles and meningoceles. In this review, we emphasize the importance and usefulness of 3D T2 DRIVE MR cisternography in localizing CSF leaks. This sequence has the advantages of effective bone and fat suppression, decreased artefacts, faster acquisition times, three-dimensional capability, y and high spatial resolution in addition to providing very bright signal from the CSF.

    2015-07-01

    Defective collagen biosynthesis in Marfan syndrome predisposes to dural defects such as dural ectasia, meningocele, and pseudomeningocele; thus, an increased index of suspicion for these conditions should be present in the clinical setting of Marfan syndrome. The authors describe a young woman with Marfan syndrome who was being treated with anticoagulants for a prosthetic heart valve and who presented with a spontaneous retroperitoneal hemorrhage requiring surgical evacuation. No CSF leak was encountered at surgery, but she developed progressively more severe positional headaches over the following year. She then experienced the sudden onset of acute urinary obstruction, at which time CT revealed a 17 × 15 × 13-cm presacral pseudomeningocele communicating with the thecal sac through a sacral bone defect. An anterior surgical approach was used for drainage of the pseudomeningocele as well as for primary closure of the dural defect with a bovine pericardial patch and autologous subcutaneous fat graft. After a short period of lumbar subarachnoid drainage of the CSF, the patient was able to resume normal activity without recurrent symptoms. To the authors' knowledge, such a pseudomeningocele in a patient with Marfan syndrome has been reported only twice, and this case features the largest pseudomeningocele to date. They also review the pertinent literature regarding presentation, diagnosis, and management of these lesions.

  12. An Unusual Presentation of Adult Tethered Cord Syndrome Associated with Severe Chest and Upper Back Pain

    2015-01-01

    Full Text Available Adult tethered cord syndrome (ATCS is a rare entity that usually presents with multiple neurological symptoms, including lower extremity pain, backache, lower extremity muscle weakness, and bowel/bladder disturbances. Prompt surgical treatment is often necessary to avoid permanent sequelae. We report a 63-year-old man with sudden-onset severe right chest and upper back pain, followed by urinary retention. His initial workup included computed tomography of the abdomen and pelvis, which showed a presacral mass. His symptom-driven neurological workup focused on the cervical and thoracic spine, the results of which were normal. Pelvic radiographs and magnetic resonance imaging of the lumbosacral spine showed spina bifida occulta, meningocele, and presacral masses consistent with a teratomatous tumor. His symptoms, except for urinary retention, improved dramatically with surgical treatment. The excised specimen contained a teratomatous lesion plus an organized hematoma. Hematoma formation was suspected as the trigger of his sudden-onset right chest and upper back pain.

    The endoscopic endonasal techniques used in skull base surgery have evolved greatly in recent years. Our study objective was to perform a qualitative systematic review of the likewise systematic reviews in published English language literature, to examine the evidence and conclusions reached in these studies comparing transcranial and endoscopic approaches in skull base surgery. We searched the references on the MEDLINE and EMBASE electronic databases selecting the systematic reviews, meta-analyses and evidence based medicine reviews on skull based pathologies published from January 2000 until January 2013. We focused on endoscopic impact and on microsurgical and endoscopic technique comparisons. Full endoscopic endonasal approaches achieved gross total removal rates of craniopharyngiomas and chordomas higher than those for transcranial approaches. In anterior skull base meningiomas, complete resections were more frequently achieved after transcranial approaches, with a trend in favour of endoscopy with respect to visual prognosis. Endoscopic endonasal approaches minimised the postoperative complications after the treatment of cerebrospinal fluid (CSF) leaks, encephaloceles, meningoceles, craniopharyngiomas and chordomas, with the exception of postoperative CSF leaks. Randomized multicenter studies are necessary to resolve the controversy over endoscopic and microsurgical approaches in skull base surgery. Copyright © 2013 Sociedad Española de Neurocirugía.

    Low back pain is probably the second most common disease entity to upper respiratory infection in developed country. We were missing at least 50% of the pathologic conditions by using conventional diagnostic modalities in low back pain. They did tell us nothing or little about facet abnormalities, lateral recesses, vertebral canal and soft tissue surrounding lumbar spines. High resolutional CT has been the biggest turning point in the diagnosis and management of low back pain. CT make a contribution to reducing the morbidity and probably the cost of evaluating patients with low back pain, and to increasing diagnostic accuracy. We observed 100 cases of lumbar CT using TCT 80A scanner for the evaluation of low back pain during the period from Apr. 1985 to Sept. 1985 at Chung-Ang University Hospital. Lumbar CT scan reveals high-positive findings (98%) in low back pain patients. Common low back disorders in CT are disc bulging (53%), herniated nucleus pulposus (32%), degenerative arthritis in posterior facet joints (27%), spinal stenosis (20%) and postoperative spines (15%). Uncommon low back disorders in CT are compression fracture of vertebral bodies, spondylolysis or spondylolisthesis, tropism, transitional vertebra, Scheueman's disease, limbic fracture, transverse process or articular process fracture, sacroiliac joint subluxation, conjoined nerve root and meningocele.

  15. Neural tube defects in Waardenburg syndrome: A case report and review of the literature.

    2017-09-01

    Waardenburg syndrome type 1 (WS1) is an autosomal dominant genetic condition characterized by sensorineural deafness and pigment abnormalities, and is caused by variants in the PAX3 homeodomain. PAX3 variants have been associated with severe neural tube defects in mice and humans, but the frequency and clinical manifestations of this symptom remain largely unexplored in humans. Consequently, the role of PAX3 in human neural tube formation remains a study of interest, for clinical as well as research purposes. Though the association between spina bifida and WS1 is now well-documented, no study has attempted to characterize the range of spina bifida phenotypes seen in WS. Spina bifida encompasses several diagnoses with a wide scope of clinical severity, ranging from spina bifida occulta to myelomeningocele. We present a patient with Waardenburg syndrome type 1 caused by a novel missense variant in PAX3, presenting with myelomeningocele, Arnold-Chiari malformation, and hydrocephalus at birth. Additionally, we review 32 total cases of neural tube defects associated with WS. Including this report, there have been 15 published cases of myelomeningocele, 10 cases of unspecified spina bifida, 3 cases of sacral dimples, 0 cases of meningocele, and 4 cases of miscellaneous other neural tube defects. Though the true frequency of each phenotype cannot be determined from this collection of cases, these results demonstrate that Waardenburg syndrome type 1 carries a notable risk of severe neural tube defects, which has implications in prenatal and genetic counseling. © 2017 Wiley Periodicals, Inc.

  16. Giant congenital melanocytic nevus (bathing trunk nevus associated with lipoma and neurofibroma: Report of two cases

    Full Text Available Giant congenital melanocytic nevi are rare and occur in about one out of every 2,00,000 to 5,00,000 births. There is a significant association between bathing trunk nevus and neurofibromatosis and lipomatosis. Apart from this, association of bathing trunk nevus with abnormalities like spina bifida occulta, meningocele, club foot and hypertrophy or atrophy of deeper structures of a limb, have been described. We are herewith reporting two cases of bathing trunk nevi. In our first case, an eight-year-old girl presented with a bathing trunk nevus studded with multiple, large nodules. Histopathological examination of the biopsy taken from one nodule revealed features of both neurofibroma and lipoma. To the best of our knowledge, features of both these hamartomas in one nodule of a single patient are probably not reported in the literature. In our second case, a 12-year-old girl presented with bathing trunk nevus and she had spina bifida occulta. She also had lipoma in the lesion of bathing trunk nevus. Both of our patients had satellite melanocytic nevi over the face, forearm, upper back and legs. Our second patient, in addition, had small melanocytic nevi over the medial canthus and sclerocorneal junction of the right eye. By the time this girl presented to us, the melanocytic nevus started fading in color and it had become brownish. We are reporting these cases for their peculiarities and for their rare features.

    Full Text Available Stem cell therapy is emerging as a viable approach in regenerative medicine. A 31-year-old male with brachial plexus injury had complete sensory-motor loss since 16 years with right pseudo-meningocele at C5-D1 levels and extra-spinal extension up to C7-D1, with avulsion on magnetic resonance imaging and irreversible damage. We generated adipose tissue derived neuronal differentiated mesenchymal stem cells (N-AD-MSC and bone marrow derived hematopoietic stem cells (HSC-BM. Neuronal stem cells expressed β-3 tubulin and glial fibrillary acid protein which was confirmed on immunofluorescence. On day 14, 2.8 ml stem cell inoculum was infused under local anesthesia in right brachial plexus sheath by brachial block technique under ultrasonography guidance with a 1.5-inch-long 23 gauge needle. Nucleated cell count was 2 × 10 4 /μl, CD34+ was 0.06%, and CD45-/90+ and CD45-/73+ were 41.63% and 20.36%, respectively. No untoward effects were noted. He has sustained recovery with re-innervation over a follow-up of 4 years documented on electromyography-nerve conduction velocity study.

    Neurofibromatosis, or von Recklinghausen's disease, is a hereditary, harmartomatous disorder that primarily involves neuro ectoderm and mesoderm. The estimated incidence is 1 in 2,500 to 3,000 births. The clinical features are skin manifestations such as cafe-au-lait spots, skeletal manifestations primarily involving vertebrae, central and peripheral nervous manifestations, and other associated abnormalities with increased risk of malignancy. The authors analysed the radiologic findings of 18 cases of patients with neurofibromatosis who visited Pusan Kosin Medical Center and Taegu Dongsan Medical Center during the last five years. All were proven by surgery, biopsy and other diagnostic criteria. The results obtained were as follows: 1. The male to female ratio was 11:7 and the age ranged from 11 months to 51 years. 2. All the cases fulfilled the diagnostic criteria of Crowe and associates. 3. Bone manifestations were present in 44% of the cases. The other radiologic findings were intrathoracic meningocele, bilateral acoustic neurinomas, mediastinal or chest wall mass shadows, and peripheral soft tissue masses. 4. One of the soft tissue masses was proved to be malignant.

    The primary goal of urologic management in children with spina bifida is to reduce the risk of urinary tract infection (UTI) and associated renal injury. While clean intermittent catheterization (CIC) has been the mainstay of treatment, recent studies have suggested that this approach is not without risk. The objective of this study was to examine the association between alternative bladder management strategies and UTI in infants and toddlers with spina bifida. A retrospective cohort study was conducted on spina bifida patients, aged 0-3 years, seen in a multidisciplinary spinal defects clinic between 2008 and 2013. Inclusion criteria included: a primary diagnosis of meningocele, myelomeningocele, or lipomyelomeningocele. Patients were excluded if they had: spina bifida who were initially managed with spontaneous voiding had a lower risk of UTI than those managed with CIC. Patients who switched to CIC after a period of initial observation with voiding did not have a significantly different risk of UTI compared with those managed with CIC alone. These findings suggest that early initiation of CIC may not be warranted in all infants with spina bifida. Further studies are needed to more clearly define optimal indications for initiation of CIC in these patients. Copyright © 2016 Journal of Pediatric Urology Company. Published by Elsevier Ltd.

    Our purpose was to review the neuroradiological features of spinal dysraphism and to correlate them with clinical findings and up-to-date embryological theory. We also aimed to formulate a working classification which might prove useful in clinical practice. We reviewed series of 986 children referred to our Spina Bifida Centre in the past 24 years. There were 353 children with open spinal (OSD) and 633 with closed (skin-covered) spinal (CSD) dysraphism. By far the most common open abnormality was myelomeningocele, and all patients with OSD had a Chiari II malformation. CSD was categorised clinically, depending on the presence of a subcutaneous mass in the back. CSD with a mass mainly consisted of lipomas with dural defects and meningoceles, and accounted for 18.8 % of CSD. CSD without a mass were simple (tight filum terminale, intradural lipoma) or complex (split cord malformations, caudal regression). Our suggested classification is easy to use and to remember and takes into account clinical and MRI features; we have found it useful and reliable when making a preoperative neuroradiological diagnosis in clinical practice.

    Several previous reports have established the Pentax Airway Scope (Pentax AWS, S-100, HOYA-PENTAX, Tokyo, Japan) as an efficient tool for endotracheal intubation in adult patients. To date, however, there are no reports on its use with the INTLOCK blade for neonatal and pediatric patients. In this case, we performed tracheal intubation using a Pentax AWS attached to a neonatal-type INTLOCK blade (ITL-N) twice, 1 day and 10 days after birth, in a neonatal patient complicated with Arnold-Chiari malformation. The patient weighed 2.2 kg and was 47 cm tall. The first operation consisted of the repair of a meningocele ; the second was for the insertion of an indwelling Ommaya reservoir. We initially attempted tracheal intubation using a Miller's laryngoscope in the first operation and a Macintosh laryngoscope in the second, but we could not achieve tracheal intubation with either of these instruments. Upon switching to a Pentax AWS with an ITL-N, however, we successfully achieved tracheal intubation in both operations. Further research is needed to facilitate the effective use of the Pentax AWS in such cases.

    We report an unusual case of agnathia-holoprosencephaly associated with Down syndrome due to a 21/21 translocation. The patient presented prenatally at 21 wks gestation. A fetal ultrasound revealed multiple CNS anomalies including hydrocephalus, compressed cerebellum, absent septum pellucidum and possible cranial meningocele or encephalocele. High resolution ultrasound & fetal karyotype were recommended. The patient refused & elected to have a pregnancy termination. Chromosomal analysis performed on products of conception revealed a 46,XY,-21,+t(21q;21q) karyotype. Fluorescence in situ hybridization was performed and confirmed the 21/21 translocation chromosome. An autopsy revealed agnathia and multiple CNS anomalies including absence of the septum pellucidum, absence of the corpus callosum, arhinencephaly, an occiptal meningoencephalocele, dilation of the lateral ventricles, and extensive dysgenesis & heterotopias of the central cerebrum & mid-brain. Additional abnormalities included a persistent left superior vena cava, atrial & ventricular septal defects, irregular length of the fingers with absence of the middle phalanges of the right 2nd and 5th & left 5th digits and bilateral simian creases. Agnathia can be an isolated abnormality but often is associated with holoprosencephaly and/or situs inversus. The majority of familial case of agnathis-holoprosencephaly was caused by an inherited unbalanced translocation resulting in duplication of 6p and monosomy of 18p. Our patient had a translocation form of trisomy 21 but did not have a phenotype consistent with Down syndrome. Trisomy 21 has not been previously reported in other cases of agnathia-holoprosencephaly. Whether the chromosomal abnormality caused the phenotypic abnormalities or if it is a coincidental finding cannot be determined.

    Neural tube defects (NTDs) are severe congenital malformations affecting 1 in every 1000 pregnancies. ‘Open’ NTDs result from failure of primary neurulation as seen in anencephaly, myelomeningocele (open spina bifida) and craniorachischisis. Degeneration of the persistently open neural tube in utero leads to loss of neurological function below the lesion level. ‘Closed’ NTDs are skin-covered disorders of spinal cord structure, ranging from asymptomatic spina bifida occulta to severe spinal cord tethering, and usually traceable to disruption of secondary neurulation. ‘Herniation’ NTDs are those in which meninges, with or without brain or spinal cord tissue, become exteriorised through a pathological opening in the skull or vertebral column (e.g. encephalocele and meningocele). NTDs have multifactorial etiology, with genes and environmental factors interacting to determine individual risk of malformation. While over 200 mutant genes cause open NTDs in mice, much less is known about the genetic causation of human NTDs. Recent evidence has implicated genes of the planar cell polarity signalling pathway in a proportion of cases. The embryonic development of NTDs is complex, with diverse cellular and molecular mechanisms operating at different levels of the body axis. Molecular regulatory events include the BMP and Sonic hedgehog pathways which have been implicated in control of neural plate bending. Primary prevention of NTDs has been implemented clinically following the demonstration that folic acid, when taken as a peri-conceptional supplement, can prevent many cases. Not all NTDs respond to folic acid, however, and adjunct therapies are required for prevention of this folic acid-resistant category. PMID:24009034

    The goal of the present study goal was to systematically confirm the previously recognized nomenclature for tethering tracts that are part of the spectrum of occult spinal dysraphic lesions. The tethering tract in 20 patients with spina bifida occulta underwent histological examination with H & E staining and epithelial membrane antigen (EMA) immunolabeling, and additional selected specimens were stained with Masson trichrome. All tethering tracts contained fibrous connective tissue. Four tracts were lined with epithelial cells and either originated within a dermoid cyst, terminated at a skin dimple/sinus opening, or had both of these characteristics. No tethering tracts exhibited EMA positivity or meningeal elements. Although all tethering tracts originated in juxtaposition to the spinal cord, their termination sites were variable. Based on histological findings and presumed embryological origin, the authors broadly classified tethering tracts terminating within the dura mater, epidural space, or lamina as "short tethering tracts" (STTs). The STTs occurred mostly in conjunction with split cord malformations and had a purely fibrous composition. Tethering tracts terminating superficial to the overlying lamina were classified as "long tethering tracts" (LTTs), and the authors propose that these are embryologically distinct from STTs. The LTTs were of two varieties: epithelial and nonepithelial, the former being typically associated with a skin dimple or spinal cord (epi)dermoid cyst. In fact, analysis of the data suggested that not every tethering tract terminating in or on the skin should be classified as a dermal sinus tract without histological confirmation, and because no evidence of meningeal tissue-lined tracts was detected, the use of the term "meningocele manqué" may not be appropriate.

    The computer tomography is useful in evaluation of bony structures and adjacent soft tissues of the lumbar spine. Recently, the multiplanar reconstruction of lumbar spine of CT of significant value for the anatomical localization and for the myelographic and surgical correlation. We observed 177 cases of lumbar spine CT, who complains of spinal symptom, during the period from Dec. 1982 to Aug. 1984. The results were as follows: 1. The sex distribution of cases were 113 males and 44 females. The CT diagnosis showed 152 cases of herniated lumbar disc, 15 cases of degenerative disease, 5 cases of spine tbc., 3 cases of spine trauma and 2 cases of meningocele. 2. CT findings of herniated disc were as follows: focal protrusion of posterior disc margin and obliteration of anterior epidural fat in all cases, indentation on dural sac in 92 cases (60.5%) soft tissue mass in epidural fat in 85 cases (55.9%), compression or displacement of nerve root sheath in 22 cases(14.4%). 3. Sites of herniated lumbar disc were at L4-L5 level in 100 cases(59.1%) and at L5-S1 level in 65 cases (38.4%). Location of it were central type in 70 cases(41.1%), left-central type in 46 cases (27.2%), right-central type in 44 cases(26.0%) and lateral type in 9 cases (5.1%). 4. The sagittal reconstruction images were helpful in evaluating neural foramina, size of disc bluge into spinal canal, especially at L5-S1, and patients with spondylolisthesis. The coronal reconstruction images were the least informative, although they contributed to the evaluation of lumbar nerve roots of course, the axial CT scans were the most sensitive and specific.

    The authors performed spinal cord ultrasonography of 21 healthy newborn infants in Gyeongsang National University Hospital. Normal spinal cord revealed low echogenecity at that of cerebrospinal fluid and was demarcated by intense reflections from its dorsal and ventral surfaces. The central canal was routinely seen as a thin linear reflection in the center of the cord. The nerve roots making up the cauda equina formed a poorly defined collection of intense linear echoes extending from the conus. On real time image, the normal spinal cord exhibited rather slow and rhythmical anteroposterior movement within the subarachnoid fluid. A distinct and rapid vascular pulsation of the spinal cord was usually recognizable. The approximate level of vertebral bodies was determined as follows; most ventrally located vertebral body was thought to be L5 and S1 was seen slightly posterior to the L5 directed inferoposteriorly. According to the above criteria terminal portions of spinal cord were seen around the L2 body in 5 MHz and pointed termination of conus medullaris was clearly seen at L2-3 junction and in upper body of L3 by 7.5 MHz. So it would be better to examine by 5 MHz for spatial orientation and then by 7.5 MHz for more accurate examination. High-resolution, real-time ultrasonography was a safe, rapid screening technique for evaluation of the spinal cord in infants. Additional applications of spinal sonography may be possible in the evaluation of neonatal syringohydromyelia and meningocele as well as intraspinal cyst localization for possible percutaneous puncture by ultrasound guidance

    A total of 168 patients with spinal tumors were evaluated with MRI. The study shows that MRI is a sensitive method for demonstration of spinal tumors. MRI also provides a possibility to separate different histological types of tumors based on their morphology and signal characteristics. Intramedullary tumors (25 cases): Ependymomas (6 cases) and astrocytomas (7 cases) were most common. Ependymomas have a more irregular signal pattern than astrocytomas. Astrocytomas are more common in the upper spine and are more often completely cystic. Contrast enhancement is important for separation of cyst, edema and solid tumor. Intradural extramedullary tumors (31 cases): Neuromas (14 cases) and meningeomas (11 cases) were most common. Neuromas always had markedly increased signal intensity on T2-weighted images. Meningeomas were only hyperintense occasionally. Neuromas were more inhomogeneous than meningeomas on T1-weighted images. Contrast enhancement is valuable for delineation of small tumors. Extradural tumors (91 cases): 76 patients had metastases, 7 primary spinal tumors and 8 multiple myelomas. T1-weighted images are almost always superior to other sequences because tumor invasion in the fatty bone marrow is seen as a low signal area in contrast to the high signal from the fat. Spinal lymphomas (14 cases): May be divided into vertebral, paraspinal and epidural tumors. Most cases have all locations. Spinal neurofibromatosis (7 cases): Most patients had multiple, often bilateral neurofibromas. One patient had a meningeomas on one spinal dysplasia with meningoceles. MRI is superior to other modalities for evaluation of the full extent of the disease. The coronal view is often valuable because of the arrangement of the tumors. In addition to providing diagnosis, MRI is of great value in treatment follow-up

    Highlights: • Various thoracic CT findings, including cysts, mediastinal masses, etc. were found. • Cysts show upper and peripheral dominant distribution. • The number, size, and distribution of the pulmonary cysts in NF-1 revealed significant correlation. • It is suspected that thoracic CT findings in NF-1 occur independently. - Abstract: Purpose: To evaluate the prevalence rates and the correlations of thoracic computed tomography (CT) findings of neurofibromatosis 1 (NF1) in 88 patients. Materials and methods: Chest CT images of 88 NF1 patients were independently reviewed by three observers, and the CT findings were evaluated. If abnormal findings were present, their number, size, and distribution were recorded. The prevalence rate of each CT finding was calculated, and the correlations between CT findings were analyzed. Results: Of the 88 cases, 13 were positive for cysts, 16 for emphysema, 8 for nodules, 8 for GGNs (ground glass nodules), 13 for mediastinal masses, 20 for scoliosis, 44 for subcutaneous nodules, and 34 for skin nodules. Cysts showed upper and peripheral dominant distributions. Regarding 13 mediastinal masses, 2 were diagnosed as malignant peripheral nerve sheath tumors (MPNSTs), 1 was diagnosed as primary lung cancer, 2 were diagnosed as lateral meningocele, 3 were diagnosed as neurofibromas, and the remaining 7 were considered neurofibromas. There was a significant correlation between the prevalence of subcutaneous nodules and that of skin nodules. Significant positive correlations were also seen between size and number, size and rate of central distribution, and number and rate of central distribution of cysts. Conclusion: Various CT findings were found in NF-1 patients, and the prevalence rates of subcutaneous and skin nodules were higher than other findings. Though the prevalence rates of subcutaneous nodules and skin nodules were significantly correlated, the other CT findings in NF-1 occurred independently. The number, size, and

    Various physiological and pathological conditions can induce significant variations in plasma concentrations of tumor markers, such as CA 19-9, which is present in the serum and amniotic fluid of pregnant women. Herein, we aimed to determine the clinical importance of maternal serum CA 19-9 levels in the diagnosis of neural tube defects (NTDs). A total of 100 women were included in this controlled cross-sectional study. Thirty-three patients whose pregnancies were complicated by isolated meningocele or meningomyelocele constituted the study group, whereas 33 normal, healthy pregnant women constituted the control group, and 34 age- and body mass index (BMI)-matched non-pregnant women were chosen for the validation group. The mean maternal serum CA 19-9 levels were 17.2 ± 17.0 IU/mL, 7.1 ± 5.9 IU/mL, and 4.7 ± 3.6 IU/mL in the study, control, and validation groups, respectively (p < 0.001). ROC analyses showed that elevated CA 19-9 values may predict NTDs (p < 0.001). The cut-off value for CA 19-9 was found to be 9.6 IU/mL at 70% (51%-84%, 95% CI) sensitivity and 84% (74%-92%, 95% CI) specificity. CA 19-9 may be a promising noninvasive marker for NTDs. Further studies are needed to reveal the clinical applicability and diagnostic potential of maternal serum CA 19-9 levels in the identification of NTDs.

    Joint hypermobility syndrome/Ehlers-Danlos syndrome hypermobility type (JHS/EDS-HT) is an evolving and protean disorder mostly recognized by generalized joint hypermobility and without a defined molecular basis. JHS/EDS-HT also presents with other connective tissue features affecting a variety of structures and organs, such as skin, eye, bone, and internal organs. However, most of these signs are present in variable combinations and severity in many other heritable connective tissue disorders. Accordingly, JHS/EDS-HT is an "exclusion" diagnosis which needs the absence of any consistent feature indicative of other partially overlapping connective tissue disorders. While both Villefranche and Brighton criteria include such an exclusion as a mandatory item, a systematic approach for reaching a stringent clinical diagnosis of JHS/EDS-HT is still lacking. The absence of a consensus on the diagnostic approach to JHS/EDS-HT concerning its clinical boundaries with similar conditions contribute to limit our actual understanding of the pathologic and molecular bases of this disorder. In this review, we revise the differential diagnosis of JHS/EDS-HT with those heritable connective tissue disorders which show a significant overlap with the former and mostly include EDS classic, vascular and kyphoscoliotic types, osteogenesis imperfecta, Marfan syndrome, Loeys-Dietz syndrome, arterial tortuosity syndrome, and lateral meningocele syndrome. A diagnostic flow chart is also offered with the attempt to support the less experienced clinician in stringently recognizing JHS/EDS-HT and stimulate the debate in the scientific community for both management and research purposes. © 2015 Wiley Periodicals, Inc.

    Full Text Available Malformações congênitas causadas pela ingestão de Mimosa tenuiflora têm sido observadas em ruminantes no semiárido do Nordeste Brasileiro. Neste trabalho foram estudadas as malformações congênitas em ruminantes diagnosticadas entre 2000 e 2008, em municípios da Paraíba, Pernambuco e Rio Grande do Norte. Durante o período foram recebidos 1.347 materiais de ruminantes para diagnóstico, desses 47 (3,48% foram dignosticados como malformações congênitas. Com base no tipo de malformação e na procedência do animal as malformações foram divididas em: 1 causadas pelo consumo de M. tenuiflora; e 2 malformações esporádicas, sem causa conhecida. De 418 materiais de ovinos, 21 corresponderam a malformações, sendo 18 (4,3% do total de materiais de malformações causadas por M. tenuiflora e 3 (0,71% de malformações esporádicas. De 434 materiais de bovinos, 14 foram diagnosticados como malformações, sendo 8 (1,84% causadas por M. tenuiflora e 6 (1,38% malformações esporádicas. De 495 materiais de caprinos, 12 apresentaram malformações, sendo 9 (1,81% causadas pela ingestão de M. tenuiflora e 3 (0,6% malformações esporádicas. As principais malformações causadas por M. tenuiflora foram artrogripose, micrognatia, palatosquise, microftalmia e hipoplasia ou aplasia unilateral ou bilateral dos ossos incisivos. As malformações esporádicas incluiram: acefalia e hermafroditismo, dicefalia e malformações de vasos intestinais em ovinos; atresia anal em três caprinos; e hidranencefalia, atresia anal, malformações de costelas com eventração, hipoplasia cerebelar e hidrocefalia, coristoma pulmonar e meningocele, e gêmeos siameses em bovinos. O caso de hipoplasia cerebelar com hidrocefalia foi negativo pela imuno-histoquímica para o vírus da diarreia viral bovina. Malformações congênitas causadas por M. tenuiflora ocorreram durante todo o ano. A maior frequência em ovinos está aparentemente associada ao consumo da
