SSK Ankara Eğitim ve Araştırma Hastanesi Nöroşirürji Kliniği, Ankara OBJECTIVE: A case with venous aneurysm causing peroneal nerve compression is presented. To our knowledge, all the cases reported on venous aneurysm-induced peripheral neuropathy have been in the upper extremity, and this is the first case of a nerve compression involving the lower extremity.

METHOD: A 43-year-old man presented with a 1-year history of weakness and numbness of his left foot. He had had a car accident 3 years ago. His symptoms had gradually worsened and resulted in a foot drop. Laboratory investigations revealed peroneal nerve compression at the caput fibula level. During surgery a venous aneurysm on the popliteal vein, which was compressing the peroneal and tibial nerves was explored in the popliteal fossa and resected completely. Following the operation his symptoms improved within some months.

CONCLUSION: Venous aneurysm should be included in the differential diagnosis in peripheral neuropathy patients with a history of trauma and also with a subcutaneous mass. The diagnosis can be made with duplex ultrasound scanning, a simple and safe method. Anahtar Kelimeler : Entrapment neuropathy, peripheral nerve compression, peroneal nerve, venous aneurysm
