Giant aneurysm arising from the anterior cerebral artery and causing an isolated homonymous hemianopsia.

A case of a giant aneurysm arising from the anterior cerebral artery and producing a left homonymous hemianopsia is presented. The aneurysm caused lateral compression of the posterior part of the optic chiasm. After preoperative dynamic assessment of the circle of Willis by angiography and by electroencephalographic recording during carotid artery compression, the aneurysm was trapped with microclips on the anterior cerebral artery proximal and distal to it. Visual field examination 6 months postoperatively showed complete visual field recovery. This is the first case of homonymous hemianopsia caused by an angiographically proven giant aneurysm of the ACA.

Aneurysm arising from the medial branch of the superior cerebellar artery.

A case is presented of an aneurysm arising from the distal portion of the medial branch of the superior cerebellar artery. The aneurysm was discovered after a subarachnoid hemorrhage and was clipped successfully. We found no similar distally located aneurysm in a review of the literature. The close relationship between the superior cerebellar artery and the posterior cerebral artery is discussed to facilitate the proper choice of surgical approach.

Dorsal paravertebral soft tissue sarcoma: considerations on the technique of surgical treatment.

Three patients are presented with soft tissue sarcomas of the dorsal paravertebral region. Wide surgical excision was possible because the spinous processes, the hemilaminae and the transverse processes adjacent to the tumour, were resected en bloc with the tumour. The key to this operation is a contralateral hemilaminectomy, which enables the resection to be carried out under full visual control of the spinal cord. No spinal cord injuries occurred. The main problem encountered after resection was pain due to instability of the spine in 2 patients. Factors determining spinal instability and indications for primary internal stabilization are discussed.

Occipital dural arteriovenous fistulas.

Occipital dural arteriovenous fistulas are discussed with reference to three cases. Two patients presented classically with pulsatile tinnitus and another one with an occipitally located intracerebral haematoma. The importance of thorough bilateral angiographic investigation including both arterial and venous phases with subtraction is stressed. Embolization of the pathological territory of the external carotid artery is the primary method of treatment, sometimes combined with intraoperative embolization. In comparison, surgical approaches are extensive and do not offer guaranteed success, but could be necessary as an adjunct to embolization.

Chronic epidural haematoma. A non-typical course of extradural haemorrhage.

4 Patients with chronic epidural haematoma are presented. Emphasis is placed a) clinically on symptoms of an intracranial hypertension and b) on the C.T.-scan demonstrating the presence of a homogeneous clot. At operation the findings were a clotted haematoma encapsulated on the dural side and the still leaking blood vessel.

Butterfly vertebra.

A patient with a so-called 'butterfly vertebra' is presented. Radiography, including computed tomography, is shown. The embryology and pathogenesis of the vertebral column with respect to vertebral abnormalities are discussed, with special reference to butterfly vertebra. Finally, attention is paid to the clinical manifestations.

Circumferential cranio-reduction.

A simple procedure for reduction of the skull capacity is presented. This operation is indicated in cases where a hygroma had produced a marked disproportion between brain volume and skull capacity. A 'double drain' should be applied for 10-14 days in order to obliterate the intermembranous space optimally.

Comparison of CT and conventional neuroradiological procedures in lesions in the proximity of the tentorial hiatus.

Seventeen cases with (obstructive) lesions in the region of the tentorial hiatus were examined with an EMI CT 1010 brain scanner, of which 8 had additional intrathecal metrizamide. Findings were compared with information received from angiographic studies and conventional contrast examinations of the intracranial CSF spaces and with CT scans of patients presenting with herniation at the tentorial hiatus. CT, including enhancement and intrathecal metrizamide, did not yield optimal information about exact localisation or infiltrative growth of lesions. A combination with conventional procedures was needed in order to obtain essential information.

Basilar impression in an achondroplastic dwarf: causative role in tetraparesis.

The neurological and radiological findings in a case of chondrodystrophic dwarfism are described. The progressive tetraparesis proved to be based on a high-level medullary compression resulting from basilar impression and upper cervical stenosis. Surgical decompression led to the disappearance of the tetraparetic phenomena. Various aspects of chondrodystrophic dwarfism and basilar impression are discussed in relation to the neurological symptomatology, and the question of whether, in general, more attention should be given to the cranio-cervical region, is raised.

Neuroradiological applications of the Ommaya reservoir system.

By way of a frontal burr hole a subcutaneous reservoir connected to a flexible catheter inserted through a foramen of Monroe into the third ventricle is installed. The use of this device facilitates contrast and radioisotope ventriculography, reducing both trauma and stress to the patient at the same time. The procedure greatly improves the quality of contrast studies in space-occupying lesions in the posterior fossa by rendering simultaneous cisternography technically possible and safe.
