Computed tomography of lipoma of corpus callosum and choroid plexus lipoma: report of two cases.

Lipoma of corpus callosum and choroid plexus lipoma are rare developmental anomalies arising as a result of maldifferentiation of primitive meningeal tissue. Two cases are reported along with a brief review of literature. The first case presented with chronic headache, and a large lipoma of corpus callosum associated with choroid plexus lipoma was discovered. The second case had no symptoms before the discovery of corpus callosal lipoma on computed tomography, which was done for a head injury. None of the lipomas showed any calcification.
