Plasmacytoma (biopsy proven)

Clinical History:
64 year old man with past medical history of HTN with complaint of abdominal pain and migratory rib, sternal and back pain for 1 year.

Diagnosis:
Plasmacytoma (biopsy proven).

MR Technique:
3T scanner (Siemens Verio) with spine coil: Image 1: T2 sagittal (TR/TE 2800/112 ms, slice thickness 3.3 mm, scan time 58 secs); Image 2: T1 sagittal ( TR/TE 600/9.4 ms, slice thickness 3 mm, scan time 3 min 8 sec; Image 3: T1 sagittal after injection of 0.1 mmol/kg of gadolinium chelate (TR/TE 636/9.4 ms, slice thickness 3 mm, scan time 4 min 10 secs); Image 4:T1 axial after injection of 0.1 mmol/kg of gadolinium chelate (TR/TE 7/2.5 ms, slice thickness 2 mm, scan time 2 min 49 secs).

Imaging Findings:
Large enhancing lesion at T11 involving vertebral body on the left and pedicle with erosion of the cortex. An adjacent soft tissue mass extends into the spinal canal and retrocrural space causing spinal stenosis and displacing the aorta anteriorly. These findings suggest the diagnosis of plasmacytoma. Multiple other vertebral body lesions are seen consistent with multiple myeloma.
