CABRINI, Marcelo F. et al. Tendinous lesions of the ankle in MRI: retrospective review in 548 exams. Rev. argent. radiol. [online]. 2009, vol.73, n.1, pp.071-083. ISSN 1852-9992.

Purpose: To determine the prevalence of several tendinous lesions of the ankle, and the MR imaging features that characterize these lesions. Materials and methods: MR images in 548 exams of ankle were retrospectively reviewed. These studies were performed during a 18-months period of time in 3 MR scanners at Hospital Fiorito (Avellaneda), Diagnóstico por Imágenes Adrogué, and Fundación Científica del Sur Avellaneda. Results: The ankle MR images (n=548) were taken from 221 women, and 327 men; median age, 47.6 years. In 60.5% studies (n=331), no pathologic images were identified. Sixty four exams (11.7%) showed some kind of tendon injury in the tibialis posterior tendon, 47 (8.6%) in the Achilles tendon, 34 (6.2%) in the peroneus brevis tendon, 27 (4.9%) in the flexor hallucis longus tendon, and 26 (4.7%) in the peroneus longus tendon. Additional findings included lesions in the flexor digitorum longus tendons (n=10), in the tibialis anterior tendon (n=6), and in the extensor digitorum longus tendons (n=3). Conclusions: The high-quality soft-tissue contrast resolution, noninvasive nature, and multiplanar capabilities of the MR images make it an excellent tool for the detection and evaluation of a variety of tendon disorders in the ankle.
