Core Tip
Core Tip: Nerve compression by a ganglion cyst is less common compared to other complications. Compression of the tibial nerve by a Baker’s cyst has been frequently reported. Cases of compression of the common peroneal nerve alone by an intraneural ganglion cyst have been reported sometimes. In our case, the peroneal nerve was compressed by an extraneural ganglion cyst, making it a very rare occurrence.
