MRI
Large shoulder joint effusion with extensive capsular nodular thickening and hyperenhancement with communicating extension into the subacromial recess. The internal contents are heterogeneous with regions of T1 hyperintense signal favoured to represent haemorrhage and T2 hypointense regions which may represent debris. Disruption of the all four rotator cuff muscles at the humeral insertion.
The imaging features are not typical for a tumour process with non-enhancing larger heterogeneous fluid collection which is centred on the shoulder joint in association with a proximal glenoid fracture.
