Part 6: Infection Case 85 Fig. 85.1 Coronal T1-weighted (a), sagittal T1-weighted (b), and axial T1-weighted (c) images show a rounded thin rim or “penumbra” of mildly hyperintense signal intensity…

Part 10: Pediatric or Developmental Musculoskeletal Conditions Case 126 Fig. 126.1 Frontal radiograph shows unusually short ribs. The spine is normal, but humeri are short and thick. The cardiothymic silhouette…

Part 8: Metabolic Musculoskeletal Conditions Case 105 Fig. 105.1 PA radiograph of the wrist (a) shows fraying and cupping of distal metaphyses of radius and ulna. Frontal image of bilateral…

Part 9: Spine Case 113 Fig. 113.1 Sagittal T2-weighted MR image of the cervical spine demonstrates near complete fusion of the C3–4, C7–T1, and T1–T2 disc space and elongation of…

Part 7: Soft Tissue Tumors Case 93 Fig. 93.1 Sagittal T1-weighted (a), sagittal T2-weighted (b), sagittal fat-suppressed T2-weighted (c), and sagittal postcontrast, fat-suppressed T1-weighted (d) images of the knee show…

Part 4: Lower Extremity Case 51 Fig. 51.1 Coronal proton density-weighted (a, b), coronal fat-suppressed T2-weighted (c), and sagittal proton density-weighted (d) images of the pelvis show that the sciatic…

Part 3: Upper Extremity Case 36 Fig. 36.1 Axial, fat-saturated, T1-weighted MR arthrogram image (a) of the shoulder shows a thickened middle glenohumeral ligament (MGHL) with absence of the anterior…

Part 5: Arthropathies Case 75 Fig. 75.1 Sagittal T1-weighted (a) and sagittal fat-suppressed T2-weighted (b) images of the ankle and adjacent foot show the navicular is displaced plantarly relative to…

Part 2: Bone Tumors Case 14 Fig. 14.1 AP (a) and lateral (b) radiographs of tibia and fibula show a lytic permeative lesion in the mid diaphysis of tibia with…
