[Spine_Case_#02] Pre-sacral Extramedullary hematopoiesis 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.. 2022. 9. 21.
[Wrist/Finger_Case_#04] flexor carpi radialis brevis vel profundus, accessory muscle 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 .. 2022. 9. 20.
[Wrist/Finger_Case_#03] Palmer classification IB3. Complete avulsion, TFCC tear, anatomy 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.. 2022. 9. 19.
[Ankle/foot_Case_#05] Fracture through the ATFL talar tunnel, lateral ankle ligament reconstruction 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.. 2022. 9. 18.
[Ankle/foot_Case_#05] [Easy level] Normal anatomy and ATFL complete tear, CFL partial tear 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.. 2022. 9. 18.
[Wrist/Finger_Case_#02] Kienböck's disease 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.. 2022. 9. 18.

[Shoulder_Case_#03] [Challenging level] Acute calcific periarthritis 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.. 2022. 9. 17.
[Knee_Case_#03] [Typical case] Flap tear of the meniscus, Changing slope sign, The nondisplaced component of a flap tear may demonstrate a changing slope contour of its superior surface. Criteria for diagnosis of a flap tear based on sagittal images include: * A vertical tear encompassing the inner third of the meniscus,either coapted or noncoapted * Relative deficiency of the inner third of the inferior meniscal surface with associated blunting of the remaining inferior l.. 2022. 9. 17.
[Ankle/foot_Case_#04] [Moderate level] Injury of flexor retinaculum, Fascial Sleeve of the Medial Malleolus The flexor retinaculum is often torn in conjunction with a tear of the superficial deltoid ligament, or in association with ankle fracture. Tears of the flexor retinaculum have been described in association with tibialis posterior tendon dislocation. An isolated tear of the flexor retinaculum is rare. “Fascial sleeve of the medial malleolus,” is composed of the superficial deltoid origin, the me.. 2022. 9. 16.
[Ankle/foot_Case_#03] [Easy level] Achilles tendon complete rupture, Typical case The spectrum of tears ranges from microtears to interstitial tears (parallel to the long axis of the Achilles), to partial tears, and eventually to complete tears (ruptures). Typically, in a young 'normal' individual, the Achilles tendon ruptures in the 'critical zone’, which is a region of relative watershed hypovascularity 2-6 cm proximal to insertion. The Achilles tendon tear classification i.. 2022. 9. 16.
[Knee_Case_#02] pullout fixation for avulsion fractures of the PCL from the tibia Treatment of avulsion fractures of the PCL depends on the degree of avulsion fracture displacement. Conservative therapy is generally performed if the degree of avulsion fracture displacement is mild, whereas surgery is performed in patients with significant displacement and posterior tibial instability. In the past, internal fixation was highly invasive, requiring a marked opening of the back o.. 2022. 9. 15.
[Shoulder_Case_#02] [Challenging level] Acute calcific periarthritis Acute calcific periarthritis (ACP) is a self-limiting, monoarticular, peri-articular process of dystrophic mineral deposition and adjacent inflammation. The majority of cases involve the shoulder. Less commonly, there may be involvement of the hip, knee, ankle, foot, elbow, wrist, and fingers. Patients present with a sudden onset of pain, localized swelling, erythema, tenderness, and restricted .. 2022. 9. 15.
[Anatomy_26] Prestyloid Recess, ulnotriquetral ligament, Ulnomeniscal Homologue -02 The prestyloid recess is a synovial-lined pouch with a direct connection to the rest of the radiocarpal compartment. It is most commonly a saccular space bordered by the meniscal homologue distally, the TFCC attachments to the ulnar styloid process proximally, and the central TFCC disk radially There are several variations in the shape of the prestyloid recess. Prestyloid recess is best seen on .. 2022. 9. 12.

[Anatomy_23] Triangular fibrocartilage complex (TFCC), wrist MRI The most important structure of the triangular fibrocartilage complex (TFCC) is the TFC proper. The ulnar structures include the meniscus homologue (MH) and ulnar collateral ligament (ulnar capsule). The volar structures include the volar radioulnar ligament, ulnotriquetral and ulnolunate ligaments. The dorsal structures include the dorsal radioulnar ligament and extensor carpi ulnaris tendon sh.. 2022. 9. 11.
