Giant craniopharyngioma evaluated by computerized axial tomography

The advent of computerized axial tomography (CAT scan) has augmented the neurologic diagnostic armamentarium dramatically. The ability of the CAT scan to differentiate and accurately locate various intracranial densities in a noninvasive manner makes it a very valuable method of investigating craniopharyngiomas. Because they are often composed of cystic, solid, and calcified portions, craniopharyngiomas are very well demonstrated, with the same CAT scan revealing ventricular size as well. A recent and representative case is reported demonstrating the correlation between the CAT scan and the operative findings.

Posterior fossa subdural hematoma in a hemophiliac.

A successfully managed case of posterior fossa subdural hematoma occurring in a hemophiliac is reported, and the rarity of this lesion is mentioned. The management of the hemophiliac who is a victim of craniocerebral trauma is discussed, with emphasis on the use of computerized tomographic scanning to obtain rapid diagnosis. The importance of prophylactic Factor VIII replacement is emphasized, and appropriate methods of Factor VIII administration are outlined.

Intraventricular fiberscopic observations in adult hydrocephalic patients.

A flexible ventriculofiberscope was used to diagnose intraventricular pathological conditions in eight adult hydrocephalic patients. In each case the entire procedure was recorded on videotape for documentation, review, and teaching. Four representative cases are presented to illustrate the use and value of this technique.
