[Rosai-Dorfman disease presenting with multiple intracranial and intraspinal masses: a case report].
Rosai-Dorfman disease (RDD), a systemic histioproliferative disorder, was first described by Rosai and Dorfman in 1969. However, only 41 cases involving the central nervous system have been reported. The authors present a rare case of RDD with multiple intracranial and spinal lesions mimicking multiple meningioma. A 59-year-old woman was admitted to our hospital with a history of bilateral visual impairment. MRI demonstrated multiple central nervous system lesions in the suprasellar region, right temporal convexity, left frontal convexity, left cerebello-pontine angle and C5 level of the spinal cord. Preoperative neuro-imaging studies suggested multiple meningioma. Subtotal removal of the suprasellar lesion was performed, followed by gamma knife radiosurgery to the residual lesion and the other intracranial lesions. All intracranial lesions disappeared following gamma knife radiotherapy. The spinal lesion, however, was completely excised one year after the initial operation following the appearance of sensory disturbance. Both intracranial and spinal lesions were diagnosed as RDD on histological examination. No recurrences have been detected on MRI two years after the initial operation. Seeing the good results already achieved by surgical removal of RDD, this case suggests that the combination of surgery and gamma knife radiotherapy might improve further.
