Extraosseous extradural tuberculous granuloma of the cervical spine: a case report and review of intraspinal granulomatous infections.

A 70-year-old woman presented with a 5-month history of tetraparesis. Her cerebrospinal fluid and roentgenographic examination of the cervical spine were both normal. Myelography showed an extradural type of spinal cord compression at the C7 level. At operation, an extraosseous extradural mass of granulation tissue was removed, which proved on histological and bacteriological examination to be a tuberculous granuloma.

Computed tomography in intracranial supratentorial osteochondroma.

A case of a huge intracranial frontoparietal osteochondroma in a 20-year-old man is reported. The presenting symptoms were headache, vomiting, and blurred vision. Apart from papilledema, no other abnormal neurological signs were present. A specific preoperative diagnosis could not be reached from the information provided by plain skull films, angiography, and radionuclide scan. The findings on computed tomography were those of a high density mass interspersed with small foci of lower densities, producing a honeycomb appearance, and surrounded by deposits of nodular calcification. The postcontrast scan showed a moderate degree of enhancement with preservation of the precontrast honeycomb pattern. These particular features may enable a correct preoperative histological diagnosis to be offered with a high degree of probability.

Spinal subdural hematoma associated with anticoagulant therapy in a patient with spinal meningioma.

A case of spontaneous subdural hematoma in the cervicothoracic region associated with a small meningioma in a patient on anticoagulant therapy is presented. The neurological complications of anticoagulant therapy are discussed briefly. Progressive neurological deterioration in a patient on anticoagulant therapy should prompt the performance of an emergency myelogram and a possible laminectomy in spite of the potential risks of these procedures. Intraspinal bleeding occurs more frequently in the form of an epidural hematoma, but the clinical presentation may not allow differentiation from a subdural hematoma. The possible causal relation between the asymptomatic spinal meningioma, the anticoagulant therapy, and the formation of the subdural hematoma is discussed.

Nasal visual field loss with intracranial lesions of the optic nerve pathways.

Five patients developed nasal visual field defects as a result of involvement of the intracranial portion of the optic nerves. The cause in each patient, respectively, was as follows: (1) dolichoectatic carotid arteries, (2) optochiasmatic arachnoiditis, (3) meningioma of the olfactory groove, (4) pituitary apoplexy, and (5) pituitary chromophobe adenoma. The common factor in these cases was probably impaired circulation in the prechiasmal arterial anastomotic network. The nasal visual field loss present in these cases was characterized by a pattern similar to that seen in glaucoma but with impairment of visual acuity. The superior nasal visual field was usually normal and the lower temporal visual field often defective.

The management of obstructive hydrocephalus by the use of external continuous ventricular drainage.

External continuous ventricular drainage (CVD) in patients suffering from obstructive hydrocephalus is being used in many neurosurgical centers as a routine procedure for the temporary relief of intracranial pressure. The results of this treatment have been insufficiently evaluated. In the present study two groups of patients were investigated. In one, CVD was never used. In the other one it was used in all cases. It was found that the use of CVD decreased mortality rate most significantly. It is recommended that CVD should be used as a temporary measure for the treatment of the increased intracranial pressure in patients suffering from obstructive hydrocephalus.

Intra-operative computerized axial tomography.

A case is presented in which the entire surgical procedure for a recurrent brain glioma was carried out on the computerized axial tomography (CAT) table. Repeated intra-operative CAT scans provided vital information as to the extent of the tumor. Using this method there was no remnant of tumor tissue detectable on the CAT scan at the end of the operation.

Neurosurgical management of the elderly patient.

The records of 59 patients above the age of 65 operated on for diverse neurosurgical problems between January 1975 and September 1976 were reviewed. It was found that in only about half of the cases was the referral diagnosis correct. Most of the referred patients diagnosed as cerebrovascular accident or senile dementia were found to be suffering from intracranial space-occupying lesions or normal pressure hydrocephalus. Post-operatively there was a significant improvement in 48% of this group of geriatric patients, with no change in 23% and a poor result in 29%. when the data on patients with benign lesions were considered separately, it was found that in this group there was a significant improvement in 60%, with no change in 23% and a poor result in only 17%.

Effect of routine bedside procedures on intracranial pressure.

The effect on intracranial pressure (ICP) of routine bedside procedures, such as changing the patient's position, suction, rotation, flexion or extension of the head, was investigated in 21 comatose patients with brain edema. Simple maneuvers, which under physiological conditions have no effect on ICP, often led to significant changes in the ICP in these patients. It is suggested that monitoring of ICP and adjustment of body position in accordance with the level of ICP become a standard procedure in neurosurgical wards.
