Baseline MRI of the shoulder. An expansile lesion involving the body of the left scapula is seen. (A) Axial T1 (TR 580, TE 9). (B) Axial STIR (TR4964, TE 60). (C) Axial Pre- (TR 698, TE 9). (D) Axial post-Gadolinium- (TR 698, TE 9). Multiple fluid/fluid levels within the lesion, perilesional edema on the fluid sensitive sequences, and diffuse lesional enhancement all suggested ABC with possible pathologic fracture.
