Hypertrophie musculaire neurogène : à propos de trois cas, imagerie et revue de la littérature

Botulinum toxin therapy for isolated first dorsal interosseous muscle pain and hypertrophy: A case report

Botulinum toxin (BTX) injection can be an effective treatment for persistent pain and functional impairment associated with hypertrophy of the first dorsal interosseous muscle. It offers a non-surgical and minimally invasive alternative for those who have failed conservative treatment, showcasing the therapeutic promise of BTX for addressing similar musculoskeletal conditions.

[Imaging of painful calf in athletes]

A painful calf is frequent in the athlete and is dominated by tennis leg. After a short anatomical review, the principal causes of calf pain in a clinical acute and chronic context are emphasized. The contribution of the different imaging modalities will be discussed, with particular attention paid to muscular lesions. A few of the more unusual causes will be discussed.

Le muscle du sportif

Traumatic muscular pathology is frequent in the athlete. Usually, these lesions heal spontaneously leaving no sequelae. One must be able to predict how long the healing process will last in order to avoid a long period of inactivity and to protect the patient from a recurrent tear. Medical imaging can define the precise location and severity of muscle traumas and detect critical elements that will delay complete repair. Sonography is the most useful and the least expensive imaging technique for analyzing muscular trauma. It provides a good study of muscle fibers, tendons, and aponeurosis but is limited in its poor visualization of the deep structures such as hamstring tendons and the difficulty in detecting muscular scar. MRI is the most sensitive imaging technique for analyzing muscular trauma. However, muscular fibers themselves are not visualized with MRI. It remains a secondary technique, adapted to the insufficiencies of sonography. Nevertheless, the exact place of medical imaging in traumatic muscular pathology remains and leaves the door open to many later studies.

Échographie des muscles

Sonography constitutes a method of choice in the evaluation of muscular structures. Traumatic lesions represent the majority of muscular injuries. A good anatomical knowledge of the weakness sites, as well as knowledge of traumatic signs and symptoms is essential in order to deliver a precise report to the referring physician. Sonography may suggest other causes of muscle lesions, tumoral or dystrophic, before confirmation by MRI.
