Unilateral accessory scapular ossicle with sprengel deformity in a trauma patient: A case report.

Herein we present a rare anatomic variation of unilateral accessory scapular ossicle in a trauma patient and its rare association with a common scapular anomaly, Sprengel deformity. Foci that appear near the inferior angle of the scapula due to failure of bony fusion during bone maturation are called accessory scapular ossicles. Sprengel deformity is defined as the congenitally high position of the scapula. The recognition of the normal variants of scapula is important, since they could be confused with other pathologies, such as fracture and pulmonary nodule in a trauma patient. Therefore, radiologists should be familiar to these entities even rarely seen.
