Extravasation of contrast medium is a complication of contrast-enhanced computed tomography studies. Clinical presentations include minimal swelling, erythema and, when the extravasated volume is large, ulceration, compartment syndrome, and skin necrosis. Here we present an 80-year-old woman with progressive swelling and extensive soft tissue necrosis of the dorsal left hand due to contrast medium extravasation. After treatment by skin graft, she showed no long-term complications. Patients at risk for contrast medium extravasation should be closely monitored and appropriately managed.

電腦斷層掃描造影劑外滲引致的廣泛性軟組織壞死

造影劑外滲是電腦斷層（CT）增強掃描的一種併發症，臨床表現包括輕微腫脹和紅斑。如果大量造影劑外滲，更會出現潰爛、筋膜間室綜合徵和皮膚壞死。本文報告一名80歲女性因造影劑外滲而出現漸進性腫脹，以及左手手背廣泛性軟組織壞死。病人接受皮膚移植治療，無長期併發症發生。應密切監察造影劑外滲病人並施以適當治療。
