Pediatric isolated oculomotor nerve palsy induced by peduncular atypical teratoid/rhabdoid tumor: case report and literature review.

Abstract

Central nervous system atypical teratoid/rhabdoid tumor (ATRT) is a rare and highly aggressive malignancy. We present the case of a 4-year-old girl with ATRT whose initial clinical sign was acute isolated oculomotor nerve palsy. While initial imaging was interpreted as normal, repeat cerebral magnetic resonance imaging with contrast indicated a compressive lesion in the left side of interpeduncular cistern. The patient underwent a craniotomy for tumor removal but expired before the first planned chemotherapy course.
