High resolution real time intraoperative ultrasound was used in a number of cases to identify, localize, and characterize intracranial abnormalities. Five case reports illustrate the advantage of this technique during neurosurgical operative procedures.

A hemangiopericytoma of the cervical spine in a 31-year-old woman is possibly the first reported in the orthopedic literature. There is some confusion about the most efficacious treatment. Based on six cases in the medical literature, it would appear that adjunctive radiation, postoperatively, helps to decrease the recurrence rate of the tumor.

A newborn male developed diffuse myoclonus. Right frontal craniotomy revealed a thin hemispheric mantle and a cyst communicating with the right lateral ventricle. In the biopsy of the cyst wall there were the characteristic findings of malakoplakia, granulomatous inflammation with von Hansemann histiocytes and Michaelis-Gutmann bodies. The child died at 1 1/2 years of age.
