Isolated Sensory Impairment of the Thumb Due to an Intraneural Ganglion Cyst in the Median NerveFrom the Departments of Neurology and Plastic and Reconstructive Surgery, Medical College of Wisconsin, Milwaukee, Wisconsin, USA Correspondence: Safwan Jaradeh MD, Department of Neurology, MCW Clinic at Froedtert, 9200 West, Wisconsin Avenue, Mìlwaukee, Wisconsin 53226, USA. We describe an unusual case of digital neuropathy of the thumb due to compression of the median nerve in the distal forearm by an extruded ganglion cyst originating from the radio-scaphoid joint of the wrist. Electrophysiologically, both conduction slowing and block of median motor and sensory axons were present across the cyst. These changes improved after surgery.
