Abstract

We present a case of medullary sclerosis of the appendicular skeleton in a patient with chronic renal insufficiency for whom MR imaging findings were char-acteristic. T1- and T2-weighted MR images showed multiple vertical lines (medullary streaks) of low signal intensity in the metaphyses and diaphyses of the distal femur and proximal tibia.

  Fig. 1 A 34-year-old man with chronic renal insufficiency and pain in both knees. A. Lateral radiograph of the left knee shows fine calcific opacities (open arrows) at the superior aspect of the patella. B. Longitudinal US of the right knee reveals discontinuity of the normal fibrillar patterns (arrows) and arc-like calcifications (open arrows), with posterior shadowing at the proximal insertion site of the patellar tendon. P= patella. C. T1-weighted sagittal MR image of the left knee shows focal thickening with inhomogeneous increased signal intensity (arrows) at the insertion site of the quadriceps tendon. D. T2-weighted sagittal MR image of the left knee shows a slight increase in signal intensity at the insertion site of the quadriceps tendon (arrows) and abnormal increased signal intensity within the popliteus muscle (open arrow). E. T1-weighted coronal MR image shows medullary streaks of low signal in the metaphyses and diaphyses of the distal femur and proximal tibia. The epiphysis of the femur and tibia were relatively spared. F. Unenhanced CT scan shows irregularly thickened trabeculae (arrows) in the bone marrow of the distal femora. Also note the presence of joint effusion (open arrows) in the suprapatellar bursae of both knees.
