An unusual presentation of a simple bone cyst in the scapula.

A 38-year-old man presented with pain in the left shoulder following a fall. A rotator cuff tear was suspected but roentgenograms revealed a lytic, expanded, multiseptate lesion of the scapula adjacent to glenoid. This was compatible with a giant cell tumor, aneurysmal bone cyst or simple bone cyst. The MRI showed rim enhancement and clinched the diagnosis of simple bone cyst. An infraspinous approach to scapula was undertaken and open biopsy confirmed the diagnosis of simple bone cyst. Definitive treatment in the form of curettage and calcium phosphate cementation was carried out. The postoperative period was uneventful. Early mobilization was started. Patient remained well on follow-up and has returned to work in a physically demanding capacity.
