Humeral and glenoid osteolytic lesions
Presentation
Left shoulder pain and swelling.
Patient Data
Ill-defined lytic lesions over the left glenoid and proximal humerus with the focal loss of the cortex at the humerus head and irregularity of the glenoid inferior cortex.
Loading images...
Abnormal signal ( low on T1/intermediate on T2/PD fs ) soft tissue lytic destructive osseous lesions involving the glenoid and proximal humerus causing the cortical destruction of the humerus and glenoid posterior cortex and a soft tissue component which expands mildly out of the posterior side of the lesions
Abnormal intrasubstance increased fluid signal and thickening along with supraspinatus, infraspinatus, and subscapularis tendons related to tendinosis
Moderate joint effusion
Subcoracoid and subacromial/subdeltoid bursa
Tenosynovitis of the long head of biceps tendon
Capsular hypertrophy and degenerative changes along with the AC joint
Acromion type II
Degenerative changes as cartilage thinning and fraying associated wth subchondral cystic changes at the glenoid bone.
Case Discussion
The glenoid and humerus lesions imaging appearances are in keeping with a malignant bone lesion.
Metastasis, chondrosarcoma, osteosarcoma and lymphoma could be considered in the differential diagnosis.
This patient had no known background of malignancy and refused biopsy or follow up management of the osteolytic lesions.
