Stereotactic interstitial radiosurgery for intracranial Rosai-Dorfman disease. A novel therapeutic approach.
BACKGROUND
Rosai-Dorfman disease is an idiopathic, histoproliferative disorder characterized by massive painless lymphadenopathy. The favorable treatment of Rosai-Dorfman disease affecting the central nervous system is surgical resection. Histological and immunohistochemical confirmation is essential for a definitive diagnosis.


METHODS
The authors report on a 10-year-old patient with Rosai-Dorfman disease of the central nervous system who presented with increased intracranial pressure. She was treated by stereotactic interstitial irradiation using iodine-125 seeds (interstitial radiosurgery).


RESULTS
Stereotactic surgery was performed without complications. The patient recovered well to a normal neurologic status. MR images showed a complete remission 49 months after treatment.


CONCLUSIONS
The presented case demonstrates the high efficacy and safety of interstitial irradiation for intracranial Rosai-Dorfman disease. Hence, interstitial radiosurgery could be an appropriate therapeutic option for high-risk resectable intracranial Rosai-Dorfman disease.
