The clivus is a component of the central skull base. Plasmacytomas rarely occurs at clivus as a local form of plasma cell tumors. Hereby we present a case of 62 year-old male patient who was diagnosed as multiple myeloma two years ago in relation to a sacral plasmoacytoma. The patient had complaints of headache and diplopia for 5 days. The magnetic resonance imaging (MRI) revealed a centrally located lesion at clivus with homogeneous isointense signal intensity on T1 and T2 weighted images. After gadolinium, homogeneous contrast enhancement was observed. The sixth cranial nerve could not be detected due to compression of the mass as the possible cause of diplopia.
