Cervical myelopathy secondary to ossification of the posterior longitudinal ligament in a Caucasian patient.
Cervical myelopathy consequent on ossification of posterior longitudinal ligament (OPLL) is very rare in Caucasians. A 65-year-old Anglo-Saxon woman developed progressive gait disturbance, paresthesia in both legs and urinary urge incontinence. Radiological examination showed OPLL from fifth to seventh cervical vertebral level; the dense OPLL was graphically displayed by three-dimensional computerized tomography. Medial corpectomy, C5 to C7, and removal of OPLL, with subsequent fusion C4 to T1 using a free fibula graft resulted in clinical improvement. Three dimensional computerized tomographic imaging is a valuable diagnostic procedure in OPLL.
Hemifacial spasm and craniovertebral anomaly.
Two patients with congenital anomaly of the craniovertebral junction causing disabling hemifacial spasm (HFS) are presented. In one patient, complete cessation of the HFS occurred for a period of two years following simple bony decompression of the craniovertebral junction raising unanswered questions as to the exact pathogenesis of HFS. Eventually both patients required microvascular decompression at the root entry zone of the facial nerve.

Familial intracranial aneurysms: report of three families.
The problem of intracranial aneurysm causing subarachnoid hemorrhage in several members of three different families is illustrated and discussed in this report.
Primary malignant tumours of the trigeminal nerve.
We report a case of primary malignant schwannoma of the trigeminal nerve, and review the 5 previously reported cases. Clinical presentation, along with radiological and pathological features are discussed.
Retinoblastoma, eosinophilic granuloma, and malignant melanoma: a case report.
The case history of a patient treated for unilateral hereditary retinoblastoma who subsequently developed malignant melanoma and eosinophilic granuloma is presented. Although the association between retinoblastoma and second malignancies including malignant melanoma is established, we have found no reports of third malignancies occurring in such individuals.
Familial intracranial gliomas.
The pedigree of two interrelated families with 10 affected members suffering from malignant supratentorial gliomas is reported. In addition, three other unrelated families with two members each who were treated for different types of brain tumors are described. Genetic implications are discussed.

Adult diastematomyelia: a complex dysraphic state.
It is rare for patients with diastematomyelia to manifest initial symptoms in adult life. Clinical, radiological, and surgical features of a patient with symptomatic adult diastematomyelia are presented. Pathogenetic mechanisms are considered to include a variety of congenital spinal anomalies, distinct from the spur, as well as mechanical factors.
Spinal subdural hematoma in association with anticoagulant therapy.
A case of spinal subdural hematoma occurring in association with anticoagulant therapy is reported. Seven similar cases from the literature are reviewed the emphasis on the clinical features, investigation, and the results of treatment. The prognosis for recovery is good, only if the condition is diagnosed and the clot evacuated before severe spinal cord compression and subsequent ischemic necrosis has occurred.

The Chiari malformation in adults.
The clinical features of the Chiari Malformation in seven adult patients are presented. It is suggested that the clinical syndromes associated with this malformation, in adults, can be classified as (a) compression of structures at the level of foramen magnum (with or without radiologically demonstrable associated bony anomaly at the cranio-vertebral junction (b) increased intracranial pressure or obstructive hydrocephalus and (c) intramedullary cervical cord syndrome. The usefulness of tomography, and demonstration of the vertebro-basilar circulation in the neuro-radiologic investigation of these patients is emphasized. The surgical procedures performed in the management of these patients are outlined.
