At initial presentation:
Monocyte number was elevated (0.8 K/µL), percent eosinophils were high (10.1%), and basophil percent was slightly low (0.6%). All other values were within normal limits.
At two weeks post-presentation, the mass was aspirated using ultrasound guidance. Twenty-four hours later a stable mass re-accumulated; at this visit, the athlete reported that the size of the mass appeared to fluctuate with activity. Aspirated fluid was consistent with a hematoma.
Ultrasound: Right retroclavicular and supraclavicular circumscribed fluid collection measuring 7.3 cm x 3.6 cm x 2.2 cm in dimension. Given proximity to the right clavicle’s prior fixation, this may be an unresolved post-operative hematoma or previously infected lymphocele. Collection is near, but not currently involving, the right subclavian vein.
Plate from previous open reduction internal fixation was identified on the inferior surface of the right clavicle. Two of the screws were slightly long medially. Case Photo #7 Case Photo #8
