Symptomatic vertebral haemangiomas: report of two cases.

The authors reported two cases of vertebral haemangiomas with spinal cord compression. The first case deteriorated during her pregnancy. Plain radiography of the thoracic spine gave the hint for the diagnosis and computed axial tomography showed the lesion.

Computed tomography of intraventricular masses.

The CT appearances in 87 patients with intraventricular mass lesion were analyzed in order to verify the characteristic finding. The pathological diagnoses included medulloblastoma in 27, astrocytoma in 16, craniopharyngioma in 15, ependymoma in 9, meningioma in 7, AVM in 4, choroid plexus papilloma and epidermoid cyst in 2 each. One each had teratoma, ependymal cyst, cysticercosis, cavernous hemangioma and hemangioblastoma.

CT diagnosis of cerebral cysticercosis.

CT findings of 132 patients with cerebral cysticercosis were analysed. The most common finding was multiple parenchymal punctate calcifications, accounting for 53 per cent; calcifications mostly scattered in both cerebral hemispheres. The second most common finding was enhancing ring(s) or nodule(s) of about 1 cm in diameter with perifocal edema, about 43 per cent.

Computed tomography in the diagnosis of central nervous system lymphomas.

CT appearances of 13 patients diagnosed as having CNS lymphoma were reviewed. Eight patients were of primary type and 5 patients had secondary CNS involvement. In primary CNS lymphoma, the median age was 62.

Ultrasound diagnosis of Dandy-Walker cyst.

A variety of congenital malformations of the brain can be diagnosed by cranial sonography. Those which alter macroscopic morphology can be recognized and their findings are similar to those seen on computed tomography and pneumoencephalography. The ultrasonic findings in Dandy-Walker cyst are described in this report.
