Lab Studies:
White blood cells 10.3, hemoglobin 15.1, hematocrit 46.3, platelets 368
Sodium 141, potassium 4.5, chloride 97, bicarbonate 28, BUN 6, creatinine 0.85, glucose 101.
Liver panel within normal limits.
C-Reactive protein 1.38, erythrocyte sedimentation rate 69

Other Studies:
Musculoskeletal ultrasound: Left clavicle in long axis view without bony or cortical irregularity. No surrounding edema noted. Pectoralis major muscle belly noted with some probable deep muscle fiber disruption at the medial clavicular attachments, with fluid noted at the clavicular attachment. Associated calcific density noted in heterogeneous echotexture.

CT Chest with contrast: Osteolytic changes with contiguous extraosseous ill-defined soft tissue with contrast enhancement at the left first costosternal joint. Differential considerations include inflammatory arthropathy and primary or metastatic neoplasm. Recommend further characterization with musculoskeletal chest wall MR.
Case Photo #3

MRI sternoclavicular joint: Arising from the left anterior left costochondral junction/chondromanubrial junction, there is enhancing soft tissue/fluid measuring up to 3.5 cm, which is seen extending into the left aspect of the manubrium and the first rib cartilage, associated with osteolysis of the manubrium. Additionally this extends to involve the left pectoralis major and the left sternocleidomastoid muscles inferior aspect of the left sternoclavicular joint. Overall findings are concerning for infectious or inflammatory process, osteomyelitis and the patient will be scheduled for same-day aspiration/biopsy.
