Figure 3d. Anaplastic large cell lymphoma in a 9-year-old boy. (a) Fast SE STIR whole-body MR image demonstrates a cortical bone lesion with increased marrow signal intensity in the right tibia (arrow) and two additional small bright subcutaneous lesions (arrowheads). (b) US scan shows that these subcutaneous lesions represent solid hypoechoic nodules, which subsequently were proved to be lymphomatous at biopsy. (c) Lateral radiograph of the right tibia demonstrates cortical destruction (arrow). (d) Anterior view from gallium 67 scintigraphy shows tracer uptake in the tibial lesion (arrow) and in one soft-tissue nodule (arrowhead).
