Peroneus brevis split tear - A challenging diagnosis: A pictorial review of magnetic resonance and ultrasound imaging - Part 2: Imaging with magnetic resonance and ultrasound.

Peroneal tendon pathology is common among physically active individuals, with tenosynovitis, tendon subluxation, split tears and rupture. However, diagnosing these conditions, particularly peroneus brevis split tears, is clinically and radiologically challenging. Magnetic resonance imaging (MRI) and ultrasound (US) can sometimes miss split tears.
