title: Intracranial lipomas. Diagnostic and therapeutic considerations.
abstract: Fourteen cases of intracranial lipomas are reported and 200 cases from the literature are reviewed. Intracranial lipomas are rare lesions of developmental origin, which mainly occur in the region of the corpus callosum, more rarely in the ambient, interpeduncular, cerebellopontine angle and sylvian cisterns. Although they are usually asymptomatic, they can sometimes show neurological symptoms, mainly epileptic seizures. Computerized tomography and magnetic resonance imaging usually lead to the diagnosis, because of the very low-density attenuation values of lipomas on CT scan and the short T1 and T2 on magnetic resonance. A direct surgical approach is only rarely indicated, whereas cases associated to hydrocephalus require a CSF shunt. The anticonvulsivant therapy usually results in remission of the seizures.
