摘要

後腹腔惡性間葉瘤是一種高度惡性且預後極差的腫瘤。我們報告一位罹患後腹腔惡性間葉瘤之三十二歲男性。臨床上病患表現出左側下肢疼痛性水腫、無痛性左腹腫塊及腹脹。病患接受腹部電腦斷層檢查顯示左側後腹腔有一巨大，顯影不均勻且含有鈣化成分之腫瘤。在磁振造影檢查中，此腫瘤在T1為主影像（T1-weighted images）表現主要為高訊號強度，在T2為主影像（T2-weighted images）表現主要為高訊號強度且腫瘤中央參雜有中度訊號強度。該腫瘤並向下擴展且侵犯到該側腰大肌。除了手術切除腫瘤外，病患並接受化學治療。然而，一個月後之電腦斷層追蹤發現有局部復發之病灶。而病患於手術十七個月後死亡。

Retroperitoneal malignant mesenchymona is a rare retroperitoneal neoplasm with poor prognosis. Here we present a patient with retroperioneal malignant mesenchymoma. A 32-year-old man presented with progressive painful swelling on his left lower leg, abdominal fullness and a palpable left abdominal mass. Imaging studies of abdomen included sonography, contrast-enhanced computed tomography (CECT) and magnetic resonance imaging (MRI). CECT showed a huge, heterogeneously enhanced tumor with multifocal intratumorous calcifications in the left retroperitoneum. On MRI, the neoplasm was predominantly hyperintense on T1-weighted MR images and predominantly hyperintense, mixed with central isointense areas on T2-weighted images. Surgical resection of this retroperitoneal neoplasm was performed, and two courses of postoperative adjuvant chemotherapy were then administered. Unfortunately, a follow-up CT study obtained 1.5 months and 11 months after the operation showed local tumor recurrence. The patient died 17 months after the initial operation.
