Clinical and radiological features of endodermal cyst in the oculomotor nerve: A case report.

We present a 9-year-old girl with an endodermal cyst of the oculomotor nerve in the left interpeduncular cistern, who had a history of left ptosis. We suggest that a cyst localized at the exit of the oculomotor nerve from the midbrain associated with oculomotor palsy may suggest this rare entity. [ABSTRACT FROM AUTHOR]
