Primary cutaneous extravertebral meningioma. Case report.

A case of cutaneous extravertebral meningioma is presented. It was diagnosed in infancy as a lumbar meningocele. Operation was initially refused but was subsequently demanded for cosmetic reasons. The findings were a very thick corrugated skin and a cutaneous meningioma connected by a fibrous tract to the dura mater. The presence of a fibrous stalk linking the tumor to the dura mater might have been the pathogenetic connection between the meningocele and cutaneous meningioma.

Aneurysmal bone cyst of spine.

Four patients (aged 5, 7, 18, and 42) suffering from spinal cord involvement due to an aneurysmal bone cyst are reported. In two cases only a preoperative radiological diagnosis was made, one of them by a CT scan. Combined surgical and radiological treatments were done in three cases with a follow-up of 16 years in one patient and 9 years in the other two. In the fourth case, presenting with a C1 lesion, after radical excision and curettage X-ray therapy was not instituted. Pathological and radiological manifestations are discussed. Therapeutic measures are reviewed.

Brain abscess and its surgical management.

A series of 56 patients with brain abscesses who were treated over a period of 23 years is reviewed. Patients with posttraumatic infections were not included. The operative mortality was 11%. Aspiration of purulent material, radical excision of the abscess, drainage of pus, or a combination of these procedures was used according to the patient's condition and the location of the abscess. The relatively low mortality may be related to the preoperative condition of these patients, who were operated upon in the subacute or chronic stage of their disease. Conservative surgery, especially when functionally important parts of the brain are involved, helps to keep the postoperative neurological deficit as low as possible. Computerized tomography is of primary importance in localizing, diagnosing, and following the evolution of a brain abscess.

Spinal intradural metastases of extraneural origin.

Three cases of intradural extramedullary (spinal subdural) metastases, originating from outside the central nervous system, are presented. Two were located at the cervico-dorsal junction, and one was mid-dorsal. A breast ductus carcinoma, a cervical neuroblastoma, and an apoduma of unknown origin, were the primary neoplasms. All presented clinically with a short history typical of cancerous spinal cord compression. Plain X-rays of the spine did not show areas of destruction. Myelography in two cases clearly suggested that intradural location of the tumour. The relative frequency of these tumours and their pathogenesis are briefly reviewed. It is stressed that primary tumours are mainly in the breast or lung. Their metastases are mainly found in the cervico-dorsal region. It is assumed that they really are metastases of the dura mater itself, growing inward. The importance of the lymphatic and venous pathways in their spread into the dura mater is emphasized.

Supratentorial and parafalcial subdural empyema diagnosed by computerized tomography. Case report.

A case is presented in which computerized tomography (CT) demonstrated a supratentorial and parafalcial purulent collection. However, neither carotid angiography nor CT revealed the small scattered pockets of pus that were found over the convexity at operation. The entire subdural space was exposed by a wide craniectomy, permitting adequate subdural drainage and decompression of the brain. It is thought that thorough drainage of the entire subdural space is crucial for the attainment of a successful result in a single-state operation.

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.

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.

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.

Traumatic carotid aneurysm secondary to cavernous sinus penetration by wood: CT features.

Transorbital penetration of the cranial cavity by a small wooden object can pass unnoticed, while producing severe, life-threatening consequences. The occurrence of a traumatic intracranial aneurysm secondary to a wooden foreign body has not been reported previously in the English literature, to our knowledge. Familiarity with the CT features of this complication is crucial since the CT findings may be the first to suggest penetration of the cavernous sinus by wood, as well as the possibility of a traumatic carotid aneurysm. The CT features of this rare complication are discussed and the pertinent literature is reviewed.

Occipital aneurysmal bone cyst: CT features.

A case of aneurysmal bone cyst arising from the lower occipital squama with intracranial extension is presented. The case is unique in that the cyst showed fluid levels on CT. Another peculiarity of this case was postoperative recurrence.
