Figure 1. 18F-FDG PET/CT at diagnosis (A) and
two months after treatment including cladribine and rituximab (R) (B).
A: PET scan at diagnosis revealing multiple hypermetabolic lesions:
vertebral body of C3, right pedicle of T3, left vertebral hemicorps of
T4, pedicle junction and left blade of T8, left acromion, bone lysis
both of humeral heads, the two cotyls, coccygeal region, left internal
tibial plateau and both femoral heads, femoral necks, per-trochanteric
regions, great trochanters, femoral diaphysis. B: follow-up PET-scan 8
weeks after immuno-chemotherapy demonstrating metabolic response with
decreased uptake of the multiple metastatic lesions.
