title: Computed tomographic presentation of granulomatous reaction from intraventricular shunt.
abstract: A case is presented in which the patient was diagnosed as having a large mass lesion arising in the region of the quadrigeminal plate. The patient had been shunted in the past for hydrocephalus. The computed tomographic picture was that of a primary brain neoplasm. At surgery extensive granulation tissue was found. The similarity between the CT presentation of this inflammatory mass and a neoplasm is emphasized.
