Figures & Tables

Fig. 1.

True positive finding on ultrasound. A 49-year-old patient with pain posterior to the left lateral malleolus for 9 months. A. Ultrasound (transverse crosssection at the level of the lateral malleolus marked with ‘f ’) revealed a peroneus brevis split rupture. B. MRI conducted 6 months after the ultrasound confirmed the peroneus brevis split rupture (proton density-weighted image with fat suppression). Straight arrows indicate the peroneus brevis split rupture, the dashed arrow points to the normal peroneus longus, and the curved arrow indicates the superior peroneal retinaculum

Fig. 2.

True positive finding on ultrasound. A 45-year-old patient with pain posterior to the right lateral malleolus for 8 months. Ultrasound (transverse cross-sectional) revealed a peroneus brevis split rupture at the level of the lower half of the lateral malleolus (A). MRI conducted 3 months after the ultrasound confirmed the peroneus brevis split rupture (B. proton density-weighted image with fat suppression). Straight arrows indicate the peroneus brevis split rupture, the dashed arrow points to the peroneus longus, and ‘f ’ shows the lateral malleolus. P brev and p longus refer to the peroneus brevis and peroneus longus
