Sinus histiocytosis (Rosai-Dorfman disease) of the suprasellar region: MR imaging findings--a case report

Abstract

Sinus histiocytosis with massive lymphadenopathy (SHML) is an uncommon disorder that typically manifests as systemic symptoms and lymphadenopathy. Extranodal, intracranial disease is uncommon. The authors report on a 15-year-old adolescent girl who had a suprasellar mass at magnetic resonance imaging. Biopsy results demonstrated lymphophagocytosis consistent with a diagnosis of SHML. The clinical, radiologic, and histologic aspects of the disease are discussed.
