The patient’s systemic-neurological examination and laboratory findings were normal. Computed tomography and magnetic resonance imaging were performed. Imaging findings showed calcified intraventricular mass and subependymal and gyral nodular lesions. There was a slight increase in ventricular volume. Surgical treatment was performed. Pathological specimens revealed the diagnosis of rhabdoid meningioma. Leptomeningeal dissemination refers to diffuse seeding of the leptomeninges by tumor metastases. To our knowledge, leptomeningeal dissemination of intraventricular rhabdoid meningioma is very rare in the literature. We aimed to discuss imaging findings and differential diagnosis of leptomeningeal dissemination of rhabdoid meningioma. Keywords : Rhabdoid meningioma, Leptomeningeal dissemination, Headache
