Case: A 39-year-old woman presented with a ganglion cyst in the carpal tunnel simultaneously compressing the right median nerve and the deep palmar branch of the ulnar nerve. During surgery, the soft tissue was exposed under the median nerve and on the deep palmar branch of the ulnar nerve running transversely in the deep area of the carpal tunnel.
Conclusion: Simultaneous compression of the median nerve and deep palmar branch of the ulnar nerve is extremely rare; however, such a pathoanatomical relationship must be considered while examining a patient because these nerves are located close to each other.
