| Popis: | OBJECTIVE To evaluate the MR imaging features of solitary plasmacytomas of the spine. METHODS The MR images of 7 patients with histologically proven solitary plasmacytomas of the spine were reviewed. RESULTS All tumors showed predominantly iso- to hypointensity relative to muscle on T1-weighted MR images and intermediate signal intensity between muscle and fat on T2-weighted images. Curvilinear low signal intensity structures were seen within the lesions on T1 and T2-weighted images in five tumors. Moderate to strong enhancement was seen in all 6 tumors that underwent contrast enhanced MR examination. All tumors showed areas of high signal intensity on T2-weighted images and heterogeneous enhancement, except the 2 largest tumors without pathologic fracture in the sacrum. Intervertebral discs were preserved in all tumors. CONCLUSION The MR imaging features that suggest plasmacytoma of the spine include predominant intermediate signal intensity on T2-weighted images, curvilinear low signal intensity structures, moderate to strong enhancement, relatively homogeneous appearance if there are no pathologic fracture and preservation of the intervertebral discs. |
