결절종으로 오인된 하지정맥류로 인한 족근관 증후군: 증례 보고

Tarsal tunnel syndrome is a nerve entrapment syndrome of posterior tibial nerve as it passes through the tarsal tunnel. The patient presented posteromedial malleolar swelling, palpable mass and pain, and was misdiagnosed as ganglion cyst in the other clinic. Aspiration and steroid injection were done for years, which had no significant effect on symptom relief. As skin lesion and pigmentation abruptly appeared around the palpable mass, MRI and physical exam were done in our hospital. The patient was diagnosed as varicose veininduced tarsal tunnel syndrome and therefore tarsal tunnel decompression following dilatated varicose vein resection was done. The patient's symptom was improved after the surgery. Therefore, herein we report this case.
