CT and MR appearance of multiple intracranial lesions associated with suprasellar dermoid cyst.

Multiple lesions associated with suprasellar dermoid cyst are well demonstrated preoperatively on computed tomography (CT) and magnetic resonance (MR) imaging. Although the presence of multiple fatty globules in ventricles and/or subarachnoid space has been thought to be evidence of ruptured dermoid cyst, there are no signs or symptoms, including operative findings, attributable to dermoid cyst rupture in our case. The distinctive CT and MR appearance is described and possible etiology of the multiple lesions is discussed.
