Lipomas constitute less than 5% of primary brain tumors. Pericallosal lipomas (PCLp) constitute almost half of all intracranial lipomas. Corpus callosal anomalies commonly occur in cases with PCLps. 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 lateral ventricles, which is a very rare presentation. 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. 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
