Sonographic Diagnosis of Nontraumatic Musculotendinous Rupture of Hamstring

With the recent advances in equipment and software, ultrasonography (US) has been widely used in the diagnosis of muscle injury. We report a case of hamstring muscle tear initially diagnosed by US and subsequently confirmed by magnetic resonance imaging (MRI). The patient received conservative treatment and rehabilitation, after which the symptoms gradually subsided. US was used as the initial tool to identify the muscle injury and to assess the severity of the tear, as this technique has been proved to be equal in sensitivity to MRI by previous researchers. We conclude that US is a reliable and cost-effective tool in the detection of muscle injuries.
