muscle herniation

bulging of muscle belly (especially on contraction) through fascial openings, or congenital defect in compartment fascia, e.g. anterior and lateral lower-leg compartments

Tibialis anterior muscle herniation is a rare clinical entity and it may not be born in mind at first in the differential diagnosis.
The sonographic examination (with a Toshiba Aplio XG device provided with a 2D 7,5 MHz linear probe, PLT-704 SBT) carried out by a research assistant practicing diagnostic ultrasonography revealed a muscle herniation that became more apparent when the patient took squatting or lunging position (Figure 2a).
The most common site of a muscle herniation in the lower leg is the tibialis anterior muscle, since the anterolateral tibial compartment is more vulnerable to traumas (5,7).
A positional variation observed in the size of the mass and a careful physical examination combined with sonographic assessment is helpful in the definitive diagnosis of muscle herniation.
Dynamic sonography revealed muscle herniation, which was more apparent when the patient took a squatting position.
MRI is also useful in the diagnosis of muscle herniation, determining the herniated muscle volume, planning surgical treatment and differentiating other soft tissue pathologies.
In conclusion, a tibialis anterior muscle herniation should be suspected in the differential diagnosis of a mass on the lower leg and, ultrasound imaging should be the preferred diagnostic method, since it is a non-invasive, relatively economical, highly accurate and readily available imaging technique.

Muscle herniation through this fascial defect can compress the nerve leading to radiating pain over the dorsum of the foot.
Another possibility is exertional compartment syndrome associated with a tear in the compartment fascia and muscle herniation.
