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.
