Extramedullary plasmacytoma of the sinonasal cavities: CT evaluation.
Computed tomography was performed in four patients with solitary extramedullary plasmacytoma of the nasal cavity and paranasal sinuses. Two tumors originated in the nasal cavity, one in the maxillary sinus, and one in the frontal sinus. Soft tissue mass(es) was seen in all patients. Bone destruction was apparent in only two patients. It seems possible to rule out carcinomas in such patients with no or subtle bony destruction. Computed tomography was also helpful for planning radiation therapy.
