Pseudocyst of humerus

Discussion:

Increased lucency in the greater tubercle is due to decrease in the trabeculae which may occur secondary to rotator cuff disorders. This should not be mistaken for a lytic bone tumor. Additional radiographic views help in identifying that the lucency is confirming to the greater tubercle of humerus. Further evaluation can be done with the MRI if the radiographs are not confirmatory and as deemed by the clinical history.
