Ultrastructural basis for different pertechnetate uptake patterns by various human brain tumours.

Patterns of pertechnetate uptake were correlated with ultrastructural properties of the endothelial wall in 14 human brain tumours. In tumours with reduced uptake of the radionuclide, intercellular tight junctions were observed whereas absence of intercellular tight junctions was characteristic of all tumours with an increased uptake of pertechnetate. In some tumours with increased uptake, fenestrated endothelial wall was seen while in others non-fenestrated wall was evident. We concluded that intercellular junctions and not fenestrations affect the permeability of brain tumours to pertechnetate.

Extracranial bone metastases from intracranial meningiomas.

Distant bone metastases in cases of intracranial meningiomas are uncommon. Two patients with meningiomas showing malignant histological features are described, in both of whom bone metastases were observed many years after cranial surgery.

Acute central and intermediate cervical cord injury.

Six cases with cervical cord contusion are described. All were over 50 years old, had an hyperextension injury of their cervical spine, suffered from tetraparesis predominant in the upper limbs and showed no X-ray evidence of injury to the cervical spine. Marked cervical spondylosis was present in five cases, one also had a narrow spinal canal. Cases No. 3 and 4 had an atypical recovery pattern. Shoulder and elbow movements improved last or not at all, while in the classic cases the hand muscles recovered last. Upper motor neuron damage was thought to be the cause, a result of intermediate instead of central cord traumatic necrosis or ischaemia. Pathological findings in case No. 5 emphasizes the possible diagnostic importance of taking lateral X-rays of the cervical spine in hyperextension. It also shows why laminectomy and/or myelotomy cannot help. Case No. 6 shows the noxious effect of shock and the effectiveness of steroid therapy.

Benign osteoblastoma of vertebral column and skull.

Three cases of benign osteoblastoma in children are reported; two in the spine and one in the occipital bone. clinical, pathological and X-ray appearance are discussed. The importance of complete removal whenever possible is stressed. Radiation therapy is not considered to be beneficial.

Intradural rupture of lumbar intervertebral disk: report of two cases with review of the literature.

Two cases of intradural rupture of lumbar intervertebral disks are described, in addition to 22 cases reported in the literature. Our case occurred among 753 herniated disks surgically treated in this department, an incidence similar to that in the literature. Clinically most cases presented as an acute cauda equina syndrome, and a myelographic block was almost always present. Prognosis is not made worse by the perforation. Various factors that might contribute to this relatively rate complication of disk disease are mentioned.

Traumatic intracerebral haematoma: complication of skull caliper traction. Case report.

Recently, a unique case of traumatic intracerebral haematoma complicating the insertion of skull calipers, has been observed. It is assumed it was due to: 1. the accidental penetration of the burr into the skull, while making the insertion hole for the caliper; 1. the failure to grip the skull with the special metal sleeve, the Blackburn skull caliper is provided with, so that the end plates were free to move in and out of the skull in this restless patient. The correct diagnosis was made only after severe uncal herniation had developed. The reasons for missing the correct diagnosis within useful time for proper treatment are considered to be: 1. carotid angiography performed too early in the process of haematoma formation: 2. the vascular displacements were only slight and not fully diagnostic; 3. a recognized complication, extradural haematoma, had already been excluded.

Multifocal glioma of the brain. Case report.

A case is presented in which two separate concurrent astrocytomas of the brain in the same patient were successfully operated on. The patient has been followed for 3 years and remains well. The authors believe that the diagnosis of multifocal tumors can be established on clinical grounds when the tumors are remote from each other, and when there has been no recurrence of neoplasm between the lesions after a long follow-up period. It is felt that a more optimistic approach to the treatment of multifocal tumors may yield good results.
