[Imaging of malignant lymphoma of muscular sites].
Seventeen cases of muscular lymphoma are reported (5 primary non-Hodgkin lymphoma, 11 secondary NHL, 1 secondary Hodgkin's disease). The psoas or gluteus muscle was involved in 10 cases, and the lower limb was affected in the remaining 7 cases. Nine cases of muscular extension of bone NHL are also reported. On sonograms these lesions were always large and less echogenic than adjacent structures, with no signs of necrosis before treatment. US and CT patterns were comparable for both primary and secondary lesions, regardless of the type of lymphoma or whether or not there was any previous bone lesion. Associated lymphomatous lesions were observed in 14 cases. On angiograms, muscular lymphomatous involvement presented a hypovascular pattern. While ultrasonography is an excellent monitoring technique for soft tissue lymphomas (specially for the lower limbs), a major contribution of CT is the detection and the follow-up of deep or thoracic wall lesions.
