11/16. Sequelae of temporal lobe herniation: MR imaging.Acute temporal lobe herniation is a serious complication that may occur with an expanding temporal or parietal lobe mass. temporal lobe herniation may produce further damage to intracranial structures due to compression or vascular compromise. Differentiation of clinical and imaging abnormalities due to the primary lesion from those related to temporal lobe herniation is essential for proper diagnosis and management. The CT and magnetic resonance findings in a 2 1/2-year-old child who survived severe temporal lobe herniation are reported.- - - - - - - - - - ranking = 1keywords = herniation (Clic here for more details about this article) |
12/16. Extramedullary hematopoiesis in a malignant meningioma.An unusual case of malignant intracranial meningioma is presented. The operative management was complicated by the abrupt development of fulminant brain edema and herniation. The tumor contained areas of extramedullary hematopoiesis, a finding not previously reported. Various pathogenetic mechanisms involved in intradural extramedullary hematopoiesis are discussed.- - - - - - - - - - ranking = 0.125keywords = herniation (Clic here for more details about this article) |
13/16. Infradiaphragmatic spinal tumours demonstrated by transfemoral epidural venography.During the last few years transfemoral epidural venography has increasingly been used for diagnosing lumbar disc herniation. Occasionally this method may reveal an unexpected malignant tumour with the clinical symptoms of lumbar disc disease. Therefore it is of interest to be acquainted with the venographic signs of malignancy in this area. Moreover transfemoral epidural venography can be of help in the delineation of a tumour in the vertebral canal. If the double-catheter method is used, the anterior epidural venous plexus will, as a rule, be adequately shown up to the level of T10. Occasionally higher thoracic levels also are visualised. The procedure can easily be performed on an out-patient basis and is well tolerated by the patient. The complication rate is very low. The use of ioxaglate (Hexabrix) minimizes the post-injection reactions to the contrast medium.- - - - - - - - - - ranking = 0.125keywords = herniation (Clic here for more details about this article) |
14/16. Lateral approach for anterior thoracic spinal lesions.A lateral approach, consisting of a modified transversectomy, hemilaminectomy, and adequate transversectomy with costectomy of 7-8 cm, was used to treat four cases of anterior or anterolateral thoracic lesions, including two cases of thoracic disc herniations, one of thoracic meningioma, and one of hypertrophic pachymeningitis. All patients presented with gait disturbance, but recovered well postoperatively except for one who needed rehabilitation of the lower extremities. This approach provides a greater access to the anterior thoracic canal, and can achieve effective anterior decompression, and a good outcome for thoracic spinal disease if recognized early.- - - - - - - - - - ranking = 0.125keywords = herniation (Clic here for more details about this article) |
15/16. CPH and hemicrania continua: requirements of high indomethacin dosages--an ominous sign?Two female patients, one with chronic paroxysmal hemicrania and one with hemicrania continua, had a continuously high requirement of indomethacin, ie, > or = 225 mg per day, for 4 and 7 years, respectively. In the hemicrania continua patient, a right (symptomatic side) C7 root affection due to disc herniation was demonstrated. Removal of the disc relieved the arm pain completely, and reduced the head pain and indomethacin requirement considerably initially. The other patient suffered from the unremitting form of chronic paroxysmal hemicrania with right-sided attacks from the age of 16. indomethacin, 200 to 250 mg per day generally kept the headache at bay, but during exacerbations, especially during menstrual periods, the dosage transitorily had to be increased to 250 to 350 mg per day. A CT scan with contrast at aged 18 (1987) was negative. In 1992, she started having new symptoms, including numbness on the ipsilateral side of the face and arm and difficulty swallowing. An MR scan showed a meningioma originating in the roof of the cavernous sinus on the symptomatic side. The meningioma was surgically removed. The postoperative indomethacin requirement was reduced, but only transiently. patients with chronic paroxysmal hemicrania (CPH) and hemicrania continua (HC) with a continuously high indomethacin requirement may have grave additional disorders and should consequently be followed closely.- - - - - - - - - - ranking = 0.125keywords = herniation (Clic here for more details about this article) |
16/16. Enhancing transdural lumbar disk herniation.Transdural migration of an intervertebral disk fragment is accompanied by more severe clinical manifestations than the more common extradural disk herniation. We report on two patients with transdural lumbar disk herniation who had had no previous surgery. In both, there was intense enhancement of the intradural disk material on magnetic resonance imaging. The pathological specimen showed vascularization of the intradural fibrocartilage in one patient.- - - - - - - - - - ranking = 0.75keywords = herniation (Clic here for more details about this article) |
