The authors report a case of an epidermoid in the quadrigeminal cistern in a 40-year-old female who presented with headache and nausea. According to the literature, epidermoids are rarely found in the quadrigeminal cistern. Additional unusual features in this case were the absence of a capsule and T1-weighted magnetic resonance images suggestive of both solid (less intense) and fluid (more intense) comnonents.
