Presentation
Atraumatic origin of anterior elbow swelling for the last 4 to 6 weeks.
Patient Data
There is encysted fluid with echoes and septa around the distal biceps tendon. It also abuts a radius near biceps insertion. No vascularity in the lesion. Normal echo pattern of the distal biceps tendon. No effusion in the anterior elbow recesses. The patent brachial artery is an ultrasound landmark for localization of the distal biceps tendon. Normal echo pattern of the median nerve locally.
Case Discussion
Findings of bicipitoradial bursitis with normal distal biceps tendon. The distal biceps tendon does have a tendon sheath so any fluid around it shouldn't be misinterpreted as tenosynovitis.
