Recurrent cystic meningioma.

A case of a cystic meningioma recurring in its cystic form, two years after the initial removal, is presented. Regarded as a true cystic meningioma, the possible aetiology of the cyst formation is suggested. As the cyst wall itself may give rise to tumour cells, it is recommended that the initial operation should be directed at total removal of the tumour mass and cyst wall, thus reducing the possibility of a tumour recurrence. A CT finding of a hypodense lesion in a patient, operated on previously for a cystic meningioma suggests a recurrence of the tumour. However, other non-neoplastic changes should be considered.

Conus ganglioglioma in a 2 1/2-year-old boy. Case report.

Gangliogliomas are rare tumors, primarily seen in patients under the age of 30 years. They occur least commonly in the spinal cord. This report presents a 2 1/2-year-old boy who harbored an intramedullary conus tumor with the light microscopic appearance of a ganglioglioma. The neurobiological behavior of this tumor is yet to be determined.

Trigeminal glycerol rhizolysis in the treatment of tic douloureux.

Eleven patients suffering from trigeminal neuralgia were treated by percutaneous glycerol trigeminal rhizolysis after visualization of the trigeminal cistern with metrizamide. In 10 of 11 cases treatment was successful and the pain disappeared. The technique of the treatment is described. This form of treatment is recommended as a successful and simple method, especially in the elderly population suffering from trigeminal neuralgia.

Spinal arachnoid cyst with unusual presentation. Case report.

A case is reported of spastic paraparesis due to a thoracic spinal arachnoid cyst. Symptoms occurred about 10 years after craniospinal injury. The histological examination revealed hemosiderin-containing macrophages trapped in the cyst wall. This finding and its possible pathogenetic implications are discussed, and the pertinent literature is reviewed.

Computerized tomography in combat-related craniocerebral penetrating missile injuries.

Our experience in the use of computerized tomography (CT) in the evaluation and treatment of combat-related penetrating missile injuries of the head in 12 cases is summarized. Advantages observed in the use of CT include accurate delineation of in-driven bony and metallic fragments, the relation of hematomas to the missile tract and detection of brain abscesses. The availability of a CT scanner for use in military medicine may further reduce the mortality and morbidity due to combat-related cranial missile injuries.

Brown-Séquard syndrome associated with brachial plexus injury in neck trauma.

A case of adult cervical trauma that resulted in a clinical picture of Brown-Séquard syndrome and unilateral brachial plexus injury is presented. Rotational hyperflexion of the cervical spine is thought to have resulted in subluxation of C5-6 with root avulsions, leading to this unusual combination of findings.

Spinal intradural lipoma with intracranial extension.

2 cases of intradural spinal lipomas with extension into the posterior fossa in infancy are presented. Clinical features included associated subcutaneous posterior spinal lipomas and hypotonia. The cases were diagnosed by metrizamide myelography and spinocranial computerized tomography scanning. Operative therapy consisted of combined suboccipital craniectomy, spinal laminotomy, flap elevation and subtotal tumor decompression. The entity is reviewed.

Delayed epidural hematoma demonstrated by computed tomography: case report.

A case of delayed visualization of an acute parietal epidural hematoma by computed tomography (CT) in a child is presented. The initial CT 21/2 hours after injury was negative. After neurological deterioration, a repeat CT scan 8 hours postinjury demonstrated a parietal epidural hematoma and a small cerebellar hematoma. The case demonstrates the need for a high level of vigilance in head trauma patients even in the face of an initially negative CT scan.

Correlation of clinical and physiological effects of cerebellar stimulation.

The value of clinical assessment of patients undergoing chronic cerebellar stimulation (CCS) is limited by lack of objective measures but neurophysiological tests can be used to "biocalibrate" the stimulator and may be used to predict effects of CCS. Eighty-seven patients undergoing CCS have been assessed clinically and neurophysiologically over the last 4 years. Somatosensory evoked responses were significantly ( p less than 0.05) reduced in amplitude in 35 patients, cortical somatosensory evoked responses in 44 patients and one or both responses were reduced in 55 patients. There were no clinical or physiological changes in 16 patients. Evoked responses showed significant changes in only 3 patients who did not show clinical improvement. The mean voltage settings were 5.2 volts and most patients were stimulated at 200 herz. These results indicate that significant changes in those somatosensory evoked potentials are a good indication of clinical benefits from CCS but clinical improvement may occur in the absence of any acute effect on evoked responses.
