abstract: A case of multiple myeloma of bone with retroperitoneal extension is reported and results of ultrasound and computed tomography imaging in this affection discussed. The tumoral mass can be evaluated with precision due to the reliability of CT scan imaging in the diagnosis of bony lesions and a positive diagnosis made and follow up reviews of changes in extra-osseous myelomatous masses conducted by combined ultrasound and CT scan imaging.
