Isolated primary craniopharyngioma of the fourth ventricle: a rare case report and literature update

The case in this article is an isolated primary fourth ventricle craniopharyngioma with no history of saddle region extension or surgery. Its clinical presentation and pathologic features support an embryologic mechanism of residual development of Rathke's capsule. It is recommended that craniopharyngiomas be included in the differential diagnosis when evaluating locoregional lesions in the posterior cranial fossa, especially if the imaging manifestations are cystic or contain calcifications.
