title: Isolated choroid plexus lipomas.
abstract: Seven patients with isolated choroid plexus lipomas were found during the consecutive evaluation of 5351 CT and 1542 MR examinations of the brain during approximately 9 months, from the diagnosis of the first case up to the last one. Five patients were adults and two were children (one neonate). The lesions were unilateral in six patients, and bilateral in one (the neonate). Their sizes ranged from 2mm to 1 cm, and they were nodular or curvilinear. The lesions were bright on spin-echo T1-weighted and water saturation MR images, and were dark on spin-echo T2-weighted and fat saturation MR images. Relatively smaller lesions (five cases) were not seen on the CT scan. We noted an approximately 0.04% frequency on the CT scan (two in 5351 CT examinations), and 0.45% frequently on the MR images (seven in 1542 MR examinations) for isolated choroid plexus lipomas.
