We report on a very rare case of co-existence of os acromiale with suprascapular osseous bridge in a dry scapula. The frequency of os acromiale alone ranges from 1.3 to 15%, while the frequency of suprascapular osseous bridge varies between 0.036% and 12.5%. We review the relative literature and emphasize the fact that such knowledge is important for a physician in order to avoid misdiagnosis of an acromion fracture and lytic lesion of the scapula.
