A Baker's Cyst Causing Common Peroneal Nerve and Tibial Nerve Entrapment Neuropathy : A Case Report / 대한정형외과학회잡지

ABSTRACT

Degenerative disc disease of the lumbar spine caused leg pain with associated calf weakness and atrophy. However, an unusual case of leg pain and calf atrophy due to neural compression is reported. We reported a rare case of a Baker's cyst causing common peroneal nerve and tibial nerve entrapment neuropathy. Initially, after arthroscopic menisectomy and cyst decompression, Baker's cyst was recurred and then open excision was done. Until 1 year after surgery, the cyst was not recurred, increased muscle bulk was noted and EMG showed improved findings. But she continued to complain of lower leg weakness and sole paresthesia owing to delayed diagnosis and cyst decompression.
