title: Regression of intracranial rosai-dorfman disease following corticosteroid therapy. Case report.
abstract: Rosai-Dorfman disease (RDD) is an idiopathic histioproliferative disorder usually presenting with massive, painless lymphadenopathy. Extranodal involvement has been reported including at least 50 cases affecting the central nervous system (CNS). The treatment of CNS RDD as reported in the literature has primarily involved a surgical technique. The authors report on the case of a 53-year-old man presenting with multiple skull base lesions mimicking meningiomas. The patient suffered visual deterioration and underwent a right orbitopterional craniotomy as well as optic nerve decompression. Histopathological analysis revealed histiocytic cells and emperipolesis consistent with RDD. Following surgery, corticosteroid agents were administered, leading to marked resolution of both the remaining surgically untreated lesions and the balance of the patient's symptoms. This report represents the first case of the resolution of intracranial RDD following corticosteroid therapy. Corticosteroid agents should be considered an effective option in the treatment of CNS RDD.
