Abstract:
We report an extremely rare case of partial scapular duplication. Mild shoulder area deformity in a newborn prompted further evaluation that included radiography, ultrasonography and spiral CT. These revealed an additional bone in the area of the left shoulder, above the humerus and lateral to the scapula. The accessory bone articulated with the upper part of the glenoid and caused caudal displacement of the humeral head. However, it did not restrict the normal range of motion in the shoulder joint.

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...
