Unlabelled: OBJECTIVES AND IMPORTANCE: Rosai-Dorfman disease (RDD) is a rare but distinctive entity of unknown etiology; isolated intracranial RDD is uncommon. Of 37 reported intracranial RDD cases, only three were reported in children.
Clinical Presentation: We report an unusual case of a 15-year-old boy presenting with 4 months history of raised intracranial pressure with visual deterioration. Computed tomography and magnetic resonance imaging revealed bilateral petroclival enhancing lesions with cavernous sinus extension mimicking meningioma. However, histological examination was diagnostic of RDD.
Intervention: The patient underwent extended right-sided middle fossa approach and near-total tumor removal from petroclival region and cavernous sinus on both sides in two stages 6 weeks apart.
Conclusion: Ours is the first case of pediatric isolated intracranial RDD presenting with giant bilateral petroclival masses successfully managed with bilateral extended middle fossa approach in two stages. An optimal treatment for RDD is not established, but complete surgical resection alone seems effective.

Article Synopsis
- Rosai-Dorfman disease (RDD) is a rare histiocytosis often presenting with systemic symptoms, but this case highlights its unusual progression to the brain after skull base involvement.
- The presented case involves a 57-year-old male with severe headaches and a tumor mass affecting several areas, culminating in surgical intervention that revealed RDD.
- The study emphasizes the need for timely surgical treatment to prevent local and systemic disease progression, despite RDD typically being regarded as benign.

Rosai-Dorfman-Destombes disease (RDD) is a rare histiocytosis characterized by accumulation of S100 + , CD68 + , and CD1a- histiocytes, with emperipolesis. It occurs predominantly in black adolescents and young adults, but rarely in Japanese children. Recently, oncogenic mutations in mitogen-activated protein kinase (MAPK) pathway genes were reported in 30-50% of patients with RDD, and several studies have described treatment of adult patients with MAPK inhibitors.
