1/93. Anterior approach to intramedullary hemangioblastoma: case report.OBJECTIVE AND IMPORTANCE: Intramedullary spinal cord tumors are generally operated on by using the posterior approach. However, the posterior approach may not be suitable for a tumor in the anterior part of the spinal cord. In this report, we describe a case of a cervical intramedullary tumor that was successfully removed by using the anterior approach. CLINICAL PRESENTATION: A 48-year-old woman presented with lower cranial nerve disturbance and motor weakness of the upper extremities. magnetic resonance imaging revealed a large extensive syrinx and an intramedullary enhanced tumor at the C6 level. The tumor was located at the left of the anterior part of the spinal cord. INTERVENTION: Based on these findings, the anterior approach was used in performing a corpectomy of C5 and C6. The tumor was highly vascular and was resected without resulting in any operative deficits. The pathological diagnosis was hemangioblastoma. CONCLUSION: The present case suggests that the anterior approach is an important option among surgical approaches to the intramedullary tumor in cases in which the tumors are small in size and are located in the anterior part of the cervical cord.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
2/93. Frontal intraosseous cryptic hemangioma presenting with supraorbital neuralgia.Primary intraosseous cranial hemangiomas are rare benign tumors comprising 0.2% of all osseous neoplasms. Symptomatic cranial cryptic hemangiomas are extremely rare. We report the case of a 43-year-old man with a cryptic hemangioma of the superior orbital rim. Radiological investigations revealed it to be an intraosseous cryptic mass which was totally excised and the supraorbital nerve was decompressed, relieving the patient of his symptoms. Histopathology showed features of an intraosseous hemangioma.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
3/93. The use of ultrasound-assisted liposuction in the treatment of an involuted hemangioma.The authors report a case of a large, residual involuted hemangioma of the facial region in a 10-year-old girl. Ultrasound-assisted liposuction was used to debulk the tumor mass and to avoid the possibility of inadvertent iatrogenic damage to the facial nerve during surgical excision.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
4/93. Multiple hemangiomas (hemangiomatosis) of the cauda equina and spinal cord. Case report.A case of multiple hemangiomas of the cauda equina nerve roots, conus medullaris, and lower spinal cord is described. The 74-year-old male patient presented with a 9-month history of progressive bilateral leg weakness. He had a history of lymphoma at the age of 39 years and renal cell carcinoma in his early 40s. Neither disease was evident at the time of this presentation. A magnetic resonance image revealed multiple enhancing nodules in the cauda equina region as well as on the pial surface of the lower thoracic spinal cord and conus medullaris. The patient underwent an L2-3 laminectomy. cauda equina nerve roots were found to be studded with numerous purple nodules, the largest measuring 6 to 8 mm. The nodules were adherent to nerve roots from which they could not be resected. Two lesions were histologically examined and found to be capillary hemangiomas. Twelve months into an uneventful postoperative course, the patient is neurologically unchanged. This unique case might represent a distinct form of hemangiomatosis confined to the cauda equina nerve roots and spinal cord.- - - - - - - - - - ranking = 4keywords = nerve (Clic here for more details about this article) |
5/93. dopamine deficiency in rubral tremor caused by midbrain hemangioma: case report.To elucidate the nigrostriatal involvement in rubral tremor, we studied single photon emission computed tomography (SPECT) imaging with [2-[[2-[[[3-(4-chlorophenyl)-8-methyl-8-azabicyclo[3.2.1]oct-2- yl]methyl](2-mercaptoethyl)amino]ethyl]amino]ethanethiolato(3-)- N2,N2',S2,S2']oxo-[1R-(exo-exo)]-[99mTc]technetium ([99mTc]TRODAT-1) in a 70-year-old woman with a midbrain hemangioma. She had developed a slow tremor in her right arm and leg after an episode of hemorrhage at the age of 28. The tremor was 3 to 5 Hz in frequency at rest, which was enhanced by outstretching the limb and action. There was no rigidity or bradykinesia. Neurological examination also revealed mild palsy of the left oculomotor nerve. The magnetic resonance imaging (MRI) of the brain showed a small hemangioma in the left midbrain localized mainly in the substantia nigra. The [99mTc]TRODAT-1 SPECT imaging revealed significantly reduced [99mTc]TRODAT-1 uptake in the left caudate and putamen, but it was only mildly reduced in the right striatum. This reduction in uptake was even more severe than that of patients with Parkinson's disease, and indicated that the dopamine function was markedly impaired in the left nigrostriatal system. The tremor had not progressed over the years, and she responded moderately to treatment with levodopa. We concluded that the rubral tremor in the right extremities was probably caused by a dopamine deficiency in the left nigrostriatal system. This suggests that a dopamine deficiency secondary to the midbrain hemangioma might have contributed to the development of the rubral tremor in this patient.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
6/93. Hemangiomatosis presenting as meralgia paresthetica.The authors present a 15-year-boy with meralgia paresthetica caused by the recurrence of a diffuse congenital hemangiomatosis in the pelvic region. Relief of the patient's symptoms was achieved by neurolysis of the lateral femoral cutaneous nerve in the thigh and partial excision of the tumor. To our knowledge, hemangiomatosis has never been suggested as a cause of meralgia paresthetica.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
7/93. hemangioma of the facial nerve.To discuss the interest of the etiologic diagnosis of a facial palsy. STUDY DESIGN AND patients: Two cases of geniculate ganglion hemangioma with progressive facial palsy are reported. RESULTS: hemangioma of the facial nerve is a rare and benign vascular tumor that originates from the venous plexus surrounding the facial nerve. The most common locations are the internal auditory canal and the geniculate ganglion. Diagnosis of these small tumors is radiological with CT-scan and MRI studies. Surgical excision through a supra-petrosal approach is the gold standard treatment. Hemangiomas of the facial nerve and particularly those developed in the geniculate ganglion area constitute a rare but not inconsiderable facial palsy etiology. An acute diagnosis and an early excision are fundamental to preserve a satisfactory facial function.- - - - - - - - - - ranking = 7keywords = nerve (Clic here for more details about this article) |
8/93. The crucial role of imaging in detection of facial nerve haemangiomas.facial nerve haemangioma is a rare benign neoplasm accounting for 0.7 per cent of all tumours involving the temporal bone. The diagnosis of a facial nerve tumour is often missed or delayed. early diagnosis is imperative as it influences the eventual outcome for facial nerve function. prognosis is related to the size of the tumour, the severity and the duration of pre-operative paralysis. The definitive diagnosis of a facial nerve tumour rests exclusively with high resolution imaging of the temporal bone using enhanced magnetic resonance imaging (MRI) and thin-sectioned computed tomography (CT). This case emphasizes the crucial role that high quality imaging can play in the diagnosis of facial nerve tumours, and elegantly illustrates the imaging features of facial nerve haemangiomas.- - - - - - - - - - ranking = 10keywords = nerve (Clic here for more details about this article) |
9/93. Neuromuscular and vascular hamartoma of the small intestine.Neuromuscular and vascular hamartoma is an extremely rare stricturing condition of the small bowel. It consists of abnormal mixtures of intestinal tissues: disorganized fascicles of smooth muscle derived from the submucosa, bundles of nonmyelinated nerve fibers with scattered abnormal ganglion cells and hemangiomatous vessels, occurring focally and causing recurrent obstructive symptoms or occult chronic gastrointestinal bleeding. In this paper we report our experience with this tumor.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
10/93. hemangioma of the porus acusticus. Impact of imaging studies: case reports.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 intratumoral 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.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
