Malignant Fibrous Histiocytoma of the Hand: MRI

惡性纖維組織細胞瘤在手部位之磁振造影影像

摘要


惡性纖維組織瘤是成人最常見之軟組織肉瘤。常見發生部位為四肢尤其下肢,頭頸部,及後腹膜腔。我們報告一病例臨床發現一無痛性軟組織腫瘤在右手部位約數月之久。磁振造影T1影像呈現中間至低訊號,在T2影像呈現高訊號影像及腫瘤內有中隔形成,經注射顯影劑後影像特徵為周邊結節狀加強顯影。手術後證實為惡性纖維組織瘤,由於其發生的部位較罕見,故提出報告。

Malignant fibrous histiocytoma is the most common soft tissue sarcoma in adults. The most common sites of involvement include the extremities, retroperitoneum, head and neck. Hand is an unusual location. We report magnetic resonance imaging (MRI) findings of a case with malignant fibrous histiocytoma. It presents as a painless soft tissue mass in the right hand.
