Abstract
Intracranial Rosai-Dorfman disease without systemic involvement is extremely rare. A 59-year-old woman
presented with headaches. Magnetic resonance imaging revealed an enhancing posterior fossa convexity lesion
with the dural tail sign. The preoperative diagnosis was meningioma. The histopathological examination revealed
reactivity for S-100 and CD68 and non-reactivity for CD1a with emperipolesis (lymphophagocytosis) characteristic of
Rosai-Dorfman disease.
