title: Cisternography and CT scanning with 111In-DTPA in evaluation of posterior fossa arachnoid cysts.
abstract: A patient with a large, long-standing posterior fossa arachnoid cyst was evaluated. Computed tomography was used to demonstrate the cyst. 1111In-DTPA cisternography demonstrated the communication of the cyst with the subarachnoid space, stasis of the 111In in the cystic space, and incomplete ascent of cerebrospinal fluid over the cerebral hemispheres.
