A Simple Bone Cyst of the Acromion: Case Report

Simple bone cysts rarely occur in the scapula, and, to our knowledge, they have not been reported in the acromion. In the present report, we present the case of a 24-year-old female patient who was successfully treated by curettage and grafting using xenografting. No recurrence findings were observed during the follow-up six months postoperatively, the patient had recovered full range of motion, and she was able to perform all routine activities satisfactorily.

(A-D) Magnetic resonance imaging scans of the 6th postoperative month: axial T1-weighted images showing an area with partial absence of a heterogenous hypointense signal related to the postoperative changes in the acromion. Coronal and sagittal lipid-suppressed T2-weighted images showing the postoperative granulation tissue, sclerosis, and a heterogenous hyperintense image with rough countour, secondary to the surgical graft material.
