A 15-year-old female Gymnastics injury. Diagnosis? • Radiology Case of the Week Figure 1. A 15-year-old female Gymnastics injury. Diagnosis? Figure 2. A. Cross-table lateral radiograph of the left knee. The patella (red arrows) is projected over the anterior femoral condyles (yellow arrow). B. Anteroposterior radiograph of the left knee. The patella (red arrows) is displaced laterally and lies beside the lateral femoral condyle (yellow arrow). C. Axial patellofemoral view of

Adolescent with Chronic Neck Pain and Suboccipital Discomfort: Diagnosis? • Xray of the Week Figure 1. CT images of the cervical spine (A) sagittal view and (B) coronal view. What is the important finding on this CT scan? Figure 2. A. Sagittal CT shows a small, round, well-corticated ossicle (yellow arrow) representing the os odontoideum separated from the underlying body of C2 (green arrow). Note the smooth, radiolucent gap between the body of C2 and the os odontoideum (red

Trauma due to motor vehicle collision. Diagnosis? • Xray of the Week Figure 1. CT images of the cervical spine (A) sagittal view and (B) coronal view. What is the important finding on this CT scan? Figure 2. CT scan of a Type I dens fracture. Red arrows point to the fracture line at the tip of the dens. Figure 3. Anderson and D’Alonzo dens fracture classification system. Diagram by Neal Joshi. Type I is an oblique avulsion fracture involving the upper tip of the dens, usual

Traumatic diaphragmatic rupture is an uncommon but important complication of thoracoabdominal trauma that may be difficult to recognize clinically. Awareness of characteristic imaging findings, particularly on multidetector CT, is essential for prompt diagnosis and appropriate management, helping to reduce complications associated with delayed or missed injury.

A 70-year-old female fell off her bed while changing a light bulb and complains of left shoulder pain. What is the diagnosis? • Xray of the Week Figure 1. Non-contrast CT of the cervical spine. What is the diagnosis? Figure 2. Non-contrast CT of the cervical spine (sagittal reconstructions): Bilateral facet dislocation at C7-T1 with anterior subluxation of C7 on T1. The inferior facets of C7 are locked anterior to the superior facets of T1 (yellow and green arrows), with ante

Cervical ribs are supernumerary ribs arising from C7 and are more frequent than commonly appreciated on CT, where they may be overlooked without deliberate scrutiny of the thoracic inlet. Recognition matters because their morphology, length, and articulation vary and can predispose to local compressive phenomena.

Hyphema refers to hemorrhage into the anterior chamber of the eye, most often secondary to blunt or penetrating trauma. On non-contrast orbital CT, hyphema appears as a hyperdense collection filling or layering in the anterior chamber, anterior to the lens.

34 M. Trauma due to falling off a roof. Diagnosis? • Xray of the Week Figure 1. Trauma due to falling off a roof. Diagnosis? Figure 2. Type B2 Lisfranc injury. (A) AP radiograph demonstrates the circled “fleck sign” or Lisfranc ligament avulsion fracture fragment. (B) Arrow demonstrates the increase in distance between the first and second metatarsals. The red lines show the misalignment or lateral displacement of the 2nd metatarsal bone over the second cuneiform bone and the
