Xanthoma disseminatum: a rare intracranial mass

We report the CT, MR imaging, and histologic findings in a patient with an intracranial mass diagnosed as xanthoma disseminatum (XD). The mass demonstrated radiographic findings typical for a glioma. However, histologic examination of brain and dermal lesions showed findings characteristic of XD. XD is a rare dermatologic disorder of unknown cause that may be accompanied by systemic manifestations. In rare cases, it can appear as an intracranial mass.
