We describe magnetic resonance imaging in the preoperative evaluation of children with popliteal pterygium syndrome to identify the position of the popliteal artery and peroneal nerve. A nine-year-old boy, with known popliteal pterygium syndrome, had a problem straightening both knees since birth. This was due to bands connecting his hamstrings to his calf muscles. He was referred for magnetic resonance imaging to evaluate the position of popliteal arteries and peroneal nerves in relation to the soft tissue bands. The magnetic resonance imaging delineated the position of the popliteal artery and peroneal nerve accurately with respect to the pterygium band. This information is crucial in the preoperative planning of treatment for children with popliteal pterygium syndrome.

磁共振成像在診斷膕翼狀胬肉綜合徵中的作用

D Chinchure、A Littooij

本文報告一宗利用磁共振成像為患有膕翼狀胬肉綜合徵的兒童進行術前評估以確定膕動脈及腓總神經位置的病例。一名9歲男童患有膕翼狀胬肉綜合徵，由於他的大腿後側肌群及小腿後側肌群有帶狀連接，自出生後兩膝關節都不能伸展。病人經轉介接受磁共振成像檢查，以評估膕動脈及腓總神經的位置及與軟組織帶的關係。磁共振成像能準確地勾畫出相對於翼狀贅片，膕動脈及腓總神經的位置。這些資料對膕翼狀胬肉綜合徵兒童患者進行術前評估相當重要。
