다발성 골수종 환자에서 일측 안면부 감각저하를 동반한 두개저형질세포종 1례

Plasmacytoma is a monoclonal neoplastic proliferation of plasma cells derived from bone marrow. Plasmacy-toma of the skull base is very rare. Recently, the authors experienced a case of a 50-year-old woman with a tumorlike lesion originating from the right sphenoid bone. The patient presented with a 3-month history of right facialpain and paresthesia. She had been diagnosed and treated with multiple myeloma for more than 5 years, althoughshe was in complete remission until recently. Imaging studies including contrast CT scan and MRI, showed ahuge, enhanced and irregular shaped lesion in the sphenoid bone along with skull base destruction and intracranialinvasion. The patient underwent transnasal endoscopic biopsy under local anesthesia. The pathology was consis-tent with a plasma cell tumor and it was confirmed as a solitary plasmacytoma of the bone of the skull base.
