The ultrasonographic and MRI exploration of the radial forearm (Figure 2, Figure 3, Figure 4, Figure 5, Figure 6) demonstrated the presence of a fluid collection around the sheaths of the following tendons: the extensor pollicis brevis (EPB), the abductor pollicis longus (APL) and the extensor pollicis longus (EPL), especially at the level of their intersection with the extensor carpi radialis brevis (ECRB) and the extensor carpi radialis longus (ECRL).
