TL;DR
A patient with chronic knee pain was found to have a rare ganglion near the popliteus tendon, which was successfully treated with a cortisone injection.
Contribution
Demonstrates the effectiveness of ultrasound-guided corticosteroid injection for treating popliteus tendon sheath ganglion.
Findings
Advanced imaging identified a ganglion at the popliteus tendon's lateral insertion.
Ultrasound-guided corticosteroid injection resolved the patient's symptoms completely.
Abstract
Popliteus tendon sheath ganglia represent a rare and frequently overlooked cause of persistent lateral knee pain. This case report describes a patient with chronic symptoms unresponsive to conservative treatment, in whom advanced imaging revealed a ganglion at the lateral insertion of the popliteus tendon. Ultrasound‐guided corticosteroid injection resulted in complete resolution of symptoms. The case highlights the importance of thorough differential diagnosis using advanced imaging and supports the effectiveness of targeted, minimally invasive interventions.
