Anomalous muscles of the upper extremity are encountered occasionally and in most cases, identification has been made at operation. Plain radiographs do not visualize soft tissues well. Magnetic resonance imaging provides good definition of soft tissue structures. We report a case of an anomalous flexor digitorum superficialis muscle in the palm, that was seen initially as a mass associated with a previous injury and pain. Magnetic resonance studies showed the mass to be a muscle belly in the palm. Preoperative identification of anomalous muscles is possible with magnetic resonance imaging.
上肢的异常肌肉偶尔会遇到，在大多数情况下，是在手术中才得以识别。普通X线平片对软组织的显影效果不佳。磁共振成像能很好地显示软组织结构。我们报告一例手掌部异常的指浅屈肌病例，该病例最初被视为与既往损伤及疼痛相关的肿块。磁共振检查显示该肿块为手掌部的一块肌腹。通过磁共振成像术前识别异常肌肉是可行的。
