Study of Median Palmar Cutaneous Nerve Involvement in a Patient with Wrist Ganglion

Background: Few reports represent palmar cutaneous nerve neuropathy in the wrist due to a ganglion cyst. Case Presentation: A 25-year-old female was presented with a mass at volar side of the wrist and hypoesthesia at the base of thenar eminence. At ulrasonographic examination, a simple cyst was detected. Sensory response of palmar cutaneous branch of median nerve was absent at the affected side. Treatment: Ultrasound guided drainage of the cyst was performed. At 3 months follow up examination, the patient was symptom-free. Learned Lessons: This case was rare among cases involving palmar cutaneous branch of median nerve due to the wrist ganglion documented by Nerve Conduction Studies (NCS).
