Large omental cyst.

Omental and mesenteric cysts are rare intra-abdominal masses in the pediatric population. When large, these lesions can mimic large-volume ascites and may not be immediately recognized. This can lead to a delay in appropriate treatment as a result of additional unnecessary tests and procedures. We present a case of a large omental cyst in an 18-month-old male with emphasis on imaging findings that can help diagnose this rare, but important entity.

Open reduction and internal fixation of a distal clavicle fracture using a clavicle hook plate.

Historically, fractures of the clavicle have been treated nonoperatively. However, it is becoming much more common for orthopedic surgeons to treat clavicle fractures with open reduction and internal fixation-particularly fractures of the lateral clavicle with high rates of nonunion, such as the Neer type II. Several techniques and devices are currently being used for clavicle fixation. We present a case of a recently developed and increasingly popular fixation device called a clavicle hook plate, used to repair a Neer type II clavicle fracture.
