The CT and MRI images revealed a PCLp cephalad to the entire antero-posterior extent of the corpus callosum continuing as bilaterally symmetrical lateral ventricular CPLps. Radiological evaluation included computed tomography (CT) and Magnetic resonance imaging (MRI) scanning. Clinical and neurological examinations were unremarkable. CASE REPORTĪ 58-year-old Arab man presented to our hospital with a 12-month history of recurrent headache. Intracranial lipomas result from anomalous differentiation of persistent primitive meninges. Although, PCLp is often described as corpus callosal lipoma, it is most often pericallosal in location. PCLps may have calcification in the periphery and may continue into the lateral ventricles, which is a very rare presentation.
PCLps constitute almost half of all intracranial lipomas and corpus callosal anomalies are commonly present in cases with PCLps.
Lipomas constitute less than 5% of primary brain tumors. The appearance of PCLp in this case does not correspond to the descriptions of any of the existing morphological types (anterior and posterior) of classification of PCLps it is rather mixed, where PCLp occupies both anterior and posterior locations around the corpus callosum. We observed a case of PCLp with peripheral calcifications associated with PCLp continuing as bilaterally symmetrical lateral ventricular choroid plexus lipomas (CPLp) without any corpus callosal or other central nervous system anomalies, and as this is not been previously reported, we are presenting it. PCLps may have calcification in the periphery and may continue into lateral ventricles, which is a very rare presentation. Although PCLp is often described as corpus callosal lipoma, it is most often pericallosal in location. Corpus callosal anomalies commonly occur in cases with PCLps. Pericallosal lipomas (PCLp) constitute almost half of all intracranial lipomas.
