A Unique Case Presentation of Bilateral Anomalous Flexor Digitorum Superficialis

OBJECTIVE: Our case presents a unique clinical presentation of bilateral abnormal palmar mases with examination findings consistent with right sided carpal tunnel as a resultant of Type III FDS anomaly. The clinical significance of such findings may help guide future clinicians to the appropriate surgical management. METHODS: This unique case report includes clinical presentation with images, preoperative imaging studies, and intraoperative surgical details/images. All work is presented in a systematic way with detailed imaging studies and background research to give the listener a further understanding of this unique case presentation and step-wise management. RESULTS: Clinically, the patient presented with abnormal palmar mass that exhibited compressive neuropathy in the median nerve distribution. Imaging studies confirmed the anomalous FDS muscle. The anomalous muscle was surgically removed and the patient had full recovery with resolution of pain and compressive neuropathic symptoms and return of adequate hand function. CONCLUSION: This case serves to provide a systematic approach to clinical and diagnostic studies for an abnormal palmar mass that may guide the clinician's diagnosis and aid in the next step in management and treatment.
