Case in brief
A 20-year-old man developed antecubital fossa pain after heavy lifting, persisting for 1 month. Ultrasound showed a well-defined cystic lesion at the brachialis myotendinous junction, and sonopalpation reproduced his symptoms. Ultrasound-guided aspiration and corticosteroid injection provided immediate relief.
What made this case unusual
The symptomatic cyst was located at the brachialis myotendinous junction, an uncommon site for an elbow cystic lesion.
Diagnostic / clinical pearl
Ultrasound can localize an elbow cystic lesion, while sonopalpation can help establish whether it corresponds to the patient’s pain.
