  journal={Skeletal Radiology},
ObjectiveThe objective was to describe the imaging findings following acute injury to the calf musculature. [] Key MethodDesign and patientsWe retrospectively reviewed 59 MR examinations in patients who sustained injuries to the calf muscle from April 2001 to September 2004 (48 men, 11 women), with an average age of 31 and 47 years respectively (range in men 20–53; range in women 33–63).

Soleus muscle injury: sensitivity of ultrasound patterns

Ultrasound is not a sensitive technique for detecting and assessing soleus traumatic tears compared with MRI, although the sensitivity is enhanced by a thorough anatomically based ultrasound examination.

Imaging Semiology: Ultrasound and MRI in the Assessment of Muscle Injury

This chapter will outline the semiology of muscle injuries, that is describe different types and signs of musculotendinous injuries including musculoskeletal strain, muscle contusion and avulsion injury through clinically applicable techniques of standard MRI and ultrasound.

Imaging of rectus femoris proximal tendinopathies

The anatomy of the two heads of rectus femoris is recalled, a reliable method of assessment with ultrasound and MRI is described and the main injury patterns are known, through the own experience and literature review.

Connective tissue injury in calf muscle tears and return to play: MRI correlation

A novel MRI grading system based on integrity of the connective tissue can be used to estimate and guide the time to return to play in calf muscle tears.

Triceps Surae Injuries

The “calf muscle,” or triceps surae, consists of three separate muscles whose aponeuroses unite to form the Achilles tendon, and distinguishing strains in the gastrocnemius from those in the soleus is particularly important for an accurate prognosis, appropriate treatment, and successful prevention of recurrent injury.

Ultrasound Imaging Evaluation of Textural Features in Athletes with Soleus Pathology—A Novel Case-Control Study

The echogenicity showed by the quantitative ultrasound imaging measurement may be a more objective parameter for the diagnosis and follow-up the soleus muscle injuries.

Radiologic Imaging of Lower Leg Injuries

This chapter aims to offer a few key points that differentiate between lower leg injuries both in clinical presentation and in imaging characteristics.

MRI assessment of calf injuries in Australian Football League players: findings that influence return to play

There is an association between missing at least one game and multiple muscle involvement, musculotendinous junction strains, deep strain location, and intramuscular tendon tears among AFL players with calf injuries, which may provide prognostic information to help guide return-to-play decisions.

The soleus muscle: MRI, anatomic and histologic findings in cadavers with clinical correlation of strain injury distribution

The normal anatomy of the soleus muscle is described using Magnetic Resonance (MR) imaging, anatomic dissection and histologic correlation in cadavers, with correlation made between the cadaveric anatomic findings and the MR imaging features.

Isolated tear of the tendon to the medial head of gastrocnemius presenting as a painless lump in the calf

An isolated tear of the tendon to the medial head of gastrocnemius should be considered in the differential diagnosis of a lump or swelling in the upper medial area of the calf and ultrasound or MRI are recommended as the investigations of choice.



Evaluation of the hamstring muscle complex following acute injury

Imaging can discriminate a hamstring tendon avulsion from musculotendinous strain and helps identify which patients necessitate surgical management as opposed to conservative treatment.

Plantaris muscle injury: evaluation with MR imaging.

Rpture of the plantaris muscle may occur at the myotendinous junction with or without an associated hematoma or partial tear of the medial head of the gastrocnemius muscle.

Tennis leg: clinical US study of 141 patients and anatomic investigation of four cadavers with MR imaging and US.

In patients with clinical findings of tennis leg who undergo US, abnormalities of the medial gastrocnemius muscle appear to be more common than those of the plantaris tendon.

Traumatic musculotendinous injuries of the knee: diagnosis with MR imaging.

MR imaging findings associated with rupture of the iliotibial tract include discontinuity and edema, which are best noted on coronal images.

Isolated rupture of the soleus muscle: a case report.

A case of an unusual cause of calf pain--an isolated rupture of the soleus muscle--that developed in a 15-year-old girl after participation in a volleyball match is presented and magnetic resonance imaging was helpful.

Differential diagnosis of calf pain with musculoskeletal ultrasound imaging

A large Baker’s cyst extending from the popliteal fossa to the junction of the gastrocnemius and Achilles tendon is confirmed at the site of the new bruising in a 68 year old woman with acute left calf pain and swelling associated with severe difficulty in weight bearing.

Fasciotomy, chronic venous insufficiency, and the calf muscle pump.

Lower extremity fasciotomy impairs long-term calf muscle pump function, as measured by APG, in patients with and without vascular injuries, and these patients are at risk for the long- term development of chronic venous insufficiency following lower extremity trauma.

Sonographic evaluation of tears of the gastrocnemius medial head ("tennis leg")

Ultrasonography may be a useful noninvasive, low‐cost modality for diagnosis and follow‐up of tennis leg.

Future studies should delineate the repair and recovery process emphasizing not only the recovery of function, but also the susceptibility to reinjury during the recovery phase, to reduce the risks of strain injury to the muscle.

In this case problem, a patient is presented who apparently injured the FHL; however, unlike most cases reported in the literature, the patient's symptoms were present in the posterior calf and were not the result of dancing.
