title: Epidermoid cyst in quadrigeminal cistern presenting with mutism.
abstract: Epidermoid cyst of the quadrigeminal cistern is uncommon, and its presentation as mutism as the main clinical finding with no other neurological finding is very rare. We report a case where the epidermoid cyst presented with progressive symptoms of absolute mutism, which improved significantly following surgery. The possible causes and pathophysiological mechanism of mutism in the lesions of this region are discussed in this paper.
