The Reversed Palmaris Longus: Sonographic Findings and Anatomical Correlation With Implications for Carpal Tunnel Syndrome Diagnosis and Management

Year: 2025

Type: article

Abstract: Anomalous muscles of the forearm, including a reversed palmaris longus, may present as masses or median nerve compression syndromes, such as carpal tunnel syndrome. In both cases, ultrasound may be used as a first-line diagnostic test. This report presents a case of a reversed palmaris longus with sonographic findings and anatomic correlation. The diagnosis of these muscular anomalies, their relationship to compression syndromes, and implications for surgical planning are discussed.
