PAPILLOMAS OF THE CHOROID PLEXUS

Abstract

Papillomas of the choroid plexus are a well known but relatively uncommon tumor in neuropathologic literature and much rarer still in surgical literature. Two cases of a true papilloma of the choroid plexus of the left lateral ventricle are here reported. In one the tumor was removed in toto at operation, and the other was encountered at autopsy. The latter is of especially great interest in that it represents an instance of "seeding" of this type of tumor throughout a portion of the ventricular system. Credence has not been given to "seeding" of papillomas of the choroid plexus, though there are several descriptive cases in the literature. <h3>REPORT OF CASES</h3><h3>Case 1 (J. S).</h3> —Solid vascular tumor of inferior medial wall of left lateral ventricle in an infant, aged 3 months. Roentgen treatment following disclosure of tumor at operation; reduction in size of tumor; excision in toto at second stage
