It has a flattened tendon distally and, after passing over the flexor retinaculum, inserts to the palmar aponeurosis superficially. As the exact opposite of this normal anatomy of palmaris longus muscle, reversed palmaris longus (RPL) has a tendinous part proximally and a muscular portion distally. RPL is a rare muscular abnormality. On MRI, RPL muscle belly is typically evident at the volar aspect of forearm, medial to the flexor carpi radialis tendon, which is of muscle signal on all sequences. Familiarity with the variant, ultrasound and MRI appearance of RPL and accurately describing relevant imaging findings is essential for guiding effective management decisions and optimizing treatment outcomes.}, number={1}, publisher={Maltepe Üniversitesi}
