Rosai-Dorfman disease (RDD) is a rare, idiopathic, benign histioproliferative disorder. Extranodal involvement is seen in around 25–40% of patients. Central nervous system manifestation of RDD is uncommon and suprasellar location of the lesion is a distinct rarity. Surgery is the cornerstone of management of intracranial RDD. However, tumor recurrence or regrowth is a potential problem. Hence, low dose conformal radiotherapy (RT) should be considered in patients undergoing subtotal resection or having the unresectable recurrent disease. Though cranial RT usually leads to satisfactory improvement of symptoms and long-term disease stabilization or regression, in few patients there may be an eventual progression of the disease for which systemic chemotherapy may be considered. We have highlighted the salient features of this enigmatic disease by citing a case of a 50-year-old male patient with suprasellar RDD treated by maximal safe surgery and deferred radiation therapy on progression.
