Intracranial Rosai-Dorfman disease with the petroclival and parasellar involvement mimicking multiple meningiomas

摘要

Rationale:Rosai-Dorfman disease (RDD) is a rare non-Langerhans cell histiocytosis. Petroclival RDD is extremely rare. To the best of our knowledge, only 7 cases of petroclival RDD have been reported so far. Herein, we present the 8th case of intracranial RDD with the petroclival and parasellar involvement mimicking multiple meningiomas.
