Demonstration of a malignant soft-tissue lymphoma during triple-phase skeletal scintigraphy

Malignant soft-tissue neoplasms may be demonstrated in the course of triple-phase skeletal scintigraphy due to the presence of either abnormal vascularity or calcifications. We report the unusual case of a malignant lymphoma which was detected in the vascular phases of a triple-phase skeletal scintigraphic study but was not visualized utilizing conventional radioangiographic techniques. Lymphoma should be included in the differential diagnosis of soft-tissue neoplasms demonstrable by scintiangiography.
