Aim: The aim of this study is to evaluate the role of magnetic resonance imaging (MRI) in the diagnosis of
lower limb traumatic muscle injuries.

Methods: From July 2016 to February 2017, MRI study of 46 patients with a history of traumatic muscle injuries to the lower limbs was retrospectively examined. The MRI study was done within a maximum of 5 days of trauma.

Results: All our 46 patients that included in our study were males; 10 out of 46 patients (19%) had normal study with no MRI evidences of muscle contusion, myotendinous strain, or tendon avulsion. The majority of remaining 37 patients, 28 cases (75%) showing injury to knee and thigh muscles while 9 cases (24%) showing ankle & leg muscles injury. The vastus intermedius muscle was the most susceptible lower limb muscle to injury in our study, 10/37 cases (27%) followed by the hamstring muscles, semitendinosous, 5/37 cases (13%) and biceps femoirs, 3/37 cases (8%); while the injury at adductor longus muscle was noted at , 3/37 cases (8%). Multi-muscles injury was seen in 6/37 cases (16%). Quadriceps tendon complete tendon avulsion (disruption) was noted in only one case (3%). A complete rupture of Achilles tendon was found in 1/37 patient (3%); a partial rupture of the Achilles tendon in 2/37 patients (6%), another 2/37 cases (6%) showing avulsion injury to the adductor longus tendon. 1/37 patient (3%) showing medical gastrocanemious muscles injury and 3/37 cases (8%) showing lateral gastrcanemious muscles injury. Associated bone fracture seen in 5 cases (2 cases femoral fracture and 1 cases tibial fractures and 2 cases both tibial and fibular fracture), meniscal tear seen in 5 cases, and ligamentous abnormalities seen in 7 cases (3 cases patellar ligament, 3 cases ACL and 2 cases both ACL and PCL).

Conclusion: MR imaging is the imaging modality of choice for evaluation of acute traumatic musculotendinous injuries of the lower limb. It can provide useful information about the extent and location of the injury as well as associated bone, meniscal, and ligamentous abnormalities.
