CASTRO-CASTILLO, Elder et al. Intracranial Rosai-Dorfman disease: an infrequent differential diagnosis for meningioma. Report of a case. Acta méd. Peru [online]. 2023, vol.40, n.1, pp.56-61.  Epub May 09, 2023. ISSN 1728-5917.  http://dx.doi.org/10.35663/amp.2023.401.2503.

Rosai-Dorfman disease is an infrequent condition with no known etiology. The intracranial presentation is even rarer, and it resembles the appearance of a meningioma in image studies. We present the case of a 38-year-old male patient who was admitted because of an extra-axial supratentorial cranial tumor, associated to mild neurological deficit. The presumptive diagnosis was convexity meningioma. After surgery, the definitive histologic diagnosis was intracranial Rosai-Dorfman disease. This condition should be considered in the differential diagnosis of an extra-axial intracranial lesion suggesting meningioma, because of similar neuroimaging results and the similar clinical picture.
