A young male had a left ankle inversion injury a few months back followed by persistent pain in the lateral ankle region. The patient presented with ankle radiograph (no copyright, not uploaded ) showing focal corticated bone just caudal to the lateral malleolus. Ultrasound revealed an ossicle in the proximal end of the anterior talofibular ligament and complete tear of the distal end of the ligament. There was associated calcaneofibular ligament sprain.
