CTICasesDisseminated extraosseous multiple myeloma
Imaging findings
Chest and abdominal CT scan demonstrates multiple soft tissue masses in the subcutaneous fat, chest wall, and liver, without bone destruction. Widespread disease involving the ribs shows no cortical bone destruction.
Key takeaways
Multiple myeloma typically presents with lytic bone lesions, but can rarely manifest as extraosseous (extramedullary) soft tissue deposits in subcutaneous fat, internal organs, or the chest wall, mimicking lymphoma.
