Large infratentorial cystic oligodendroglioma in a pregnant patient: A case report of a rare presentation and literature review

Oligodendrogliomas (ODGs) are rare brain tumors in adults, mostly presenting as a supratentorial solid mass, while less than 10% occur infratentorially. Infratentorial cystic ODGs are extremely rare. We reported a large partially cystic cerebellar ODG in a 31‐week pregnant patient with an unusual presentation and discussed the challenging management.
