Plasma cell neoplasms are classified as plasma cell myelomas, plasmacytomas, immunglobulin deposit diseases, POEMS syndrome (osteoclastic myeloma) and light chain diseases. Solitary plasmacytoma is a local primary bone tumor composed of malignant plasma cells, forming 10% of the plasma cell neoplasms. Our case was important because of rarity of vertebral localized plasmacytoma causing acute paraplegia. An 80-year-old male patient was admitted to the emergency room with sudden onset weakness in the lower extremities. The patient, who had no trauma, had no complaints on his follow-up with the diagnosis of costal solitary plasmacytoma 20 years ago. He did not have comorbidities either. Patient was conscious, oriented and cooperated. Diagnose was T6 vertebra leveled ASIA-A spinal cord injury. Aortic dissection was not considered at the diagnosis. Cranial CT was usual. In cervical, thoracic and lumbar MRI images, an intradural extramedullary isointense mass was found that posteriorly compresses spinal cord at the T6 vertebral region in the T2 sequence. The mass was removed. Pathologic result of the mass was reported as plasmacytoid diffuse tumor proliferation. In PET-CT: foci of multiple localization, intense, increased FDG involvement without computerized tomography correspondence were detected.

In cases with back pain and weakness in lower exremities tumoral stuctures even diagnosed long ago and accepted as recovery should be considered.
