Abstract:
Intraosseous pneumatocyst of the iliac bone is usually an innocuous incidental finding with characteristic radiographic features. Because this entity is uncommon and has not been described in the orthopaedic literature, many orthopaedic surgeons are unfamiliar with the entity. Three cases of intraosseous pneumatocyst of the iliac bone are presented to illustrate some of the imaging features to assist in recognizing it for what it is: an innocuous incidental finding that should not prompt invasive procedures such as a biopsy.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
