[POEMS syndrome: imaging of skeletal manifestations, a study of 8 cases].
OBJECTIVE
To describe the imaging features of POEMS, and to compare our experience of 8 cases to a review of literature.


METHODS
This retrospective study included 8 patients (6 men, 2 women) with POEMS. Plain radiographs (8 patients), CT (6), MR (2) were performed.


RESULTS
Topographic localizations of POEMS were pelvis (7 cases), spine (5), femur (1), humerus (1), rib cage (1). Focal bone lesions, multiple (5 cases) or solitary (3 cases), were sclerotic in 4 cases, mixed lytic-sclerotic (lytic center and sclerotic rim) in 3 cases and one patient had an osteolytic lesion with sclerotic margins associated with many osteosclerotic lesions. Profilerative osseous changes were seen in 4 cases (pelvis, spine, tibia). MR imaging was performed in 2 patients: in one patient MR imaging revealed areas of low signal intensity on spin echo T1- and T2-weighted images in vertebral bodies, the other showed a lesion of low signal intensity on spin echo T1-weighted and high signal intensity on T2-weighted images in the ilium and adjacent soft tissue.


CONCLUSIONS
The imaging features commonly observed in POEMS syndrome are sclerotic and mixed lytic-sclerotic lesions, particularly in the pelvis and spine. Proliferative new bone formation is detected in 50%. MR imaging correlates with ostesclerotic or mixed lytic-sclerotic appearance.
