37-year-old woman with known dyserythropoiesis who reported pain after trauma Pre-sacral Extramedullary hematopoiesis Lobulated, pre-sacral lesion, similar T1 and T2 hypointense characteristic as the adjacent sacral bodies. Mild bone expansion with T1 hyper-intense foci,, which could be due to prevertebral hematoma and combined fat deposits. Soft tissue density lesion immediately in front of the..

The flexor carpi radialis brevis vel profundus extends from the distal radius to the capitate and base of the third and fourth metacarpals. It passes between the pronator quadratus and FCR muscles. Many accessory muscles have been described in the hand. Most are asymptomatic, but they can be a cause of compressive neuropathy or a palpable soft tissue mass. Detection can be difficult because the ..

Illustration of IB complete tear showed the detachment of both the fovea and the styloid insertions of the TFC. It involves both the foveal and the styloid insertions of the TFC and shows the irregular high signal intensity. Other signs may include altered morphology, focal synovitis, and fluid accumulation. The complete tear is typically associated with DRUJ instability. Theoretically, it may r..

When instability persists despite an anatomic repair, many surgeons turn to anatomic lateral ankle ligament reconstruction with autogenous or allogenic tendons. Several techniques have been described and most require the creation of two transosseous tunnels in the distal fibula, one for the ATFL and one for the CFL. The popularity of these procedures has been increasing over the last decade with..

ATFL The ATFL is best imaged on axial T1 or high-resolution PD MR images, appearing as a flat, thin, homogeneous band of low signal intensity arising from the anterior margin of the lateral malleolus and coursing anteromedially downward to attach onto the neck of the talus, just anterior to the fibular articular cartilage. The CFL is large, strong, and cordlike. It arises from the deep aspect of..

Stage I • Bone marrow edema due to ischemic damage without morphological changes • Normal density of the lunate in radiography and attenuation at CT scan • Low signal intensity on T1-weighted images and usually hyperintense on T2-weighted fat-suppressed images. Stage II • Sclerosis of the lunate bone due to chronic ischemic damage • Increased density in radiography with preserved morphology • CT..

Supraspinatus calcific tendinitis is well known; However, calcific deposits may occur less commonly in other structures in and around the shoulder joint (The long head of the biceps tendon, labrum, and periarticular soft tissue). In view of involvement of these other sites, the more appropriate term for the condition is calcific periarthritis Small calcifications may sometimes be missed, especia..
