Computed tomography of choroid plexus lesions.

Computed tomographic (CT) and clinical findings in 14 patients with 17 lesions of the choroid plexus are presented. Primary neoplasms are the most common lesions in this series and include papillomas, meningiomas, carcinoma, astrocytoma, and teratocarcinoma. There are five vascular lesions, consisting of cavernous angiomas, hemangiomas, and an arteriovenous malformation. One patient had bilateral xanthogranulomas. There was association between cavernous angiomas and Sturge-Weber, and between meningiomas and neurofibromatosis. Useful distinguishing clinical and CT features between the different types of lesions are discussed.
