Tibialis anterior partial rupture mimicking muscle hernia: a rare case report

Rupture of tibialis anterior tendons is infrequently described in literature, and those described were around the ankle, either at the origin or in the tendon substance. To our known knowledge only very few cases of rupture of the tibialis anterior at musculotendinous junction were reported. We highlight the occurrence of rupture at the musculotendinous junction in tibialis anterior muscle after trauma, presenting as a soft tissue mass, the need to differentiate it from traumatic muscle hernia, mechanism of injury and its ultrasound and MRI findings.
