摘要
硬纖維瘤是一種因為纖維組織過度增生的良性軟組織腫瘤，常對周圍正常組織做廣泛性浸潤，造成手術時完全切除之困難，而有很高的復發率。手術前的放射線學檢查，尤其是電腦斷層檢查，能提供良好的病灶定位及顯現病灶範圍，作為手術之參考藍圖。本文包括榮民總醫院及台中分院9個病例，報告其臨床與放射線學檢查發現。常規素片發現有異常軟組織腫塊者5例，骨骼變化4例（壓力性腐損3例、骨膜增生型1例）；接受電腦斷層掃瞄者有5例，在注射對比劑前之衰減值較正常肌肉組織低者2例、相等者2例、注射對比劑後3例（有1例為多發性有2處病灶）皆有影像增強現象，呈現高與高低混合衰減值區，2例只做對比後掃瞄者，各為高與高低混合值區；接受血管攝影檢查者4例，為程度不等的多血管區，無惡性腫瘤血管徵象。手術後復發率有5例11次。放射線學檢查以電腦斷層掃瞄為最理想工具。

Extra-abdominal desmoid tumor, a benign soft tissue tumor, due to unusual proliferation of fibrous tissue, chiefly composed of mature fibroblast (spindle-cell) and collagen fiber. Characterized by widespread infiltration of surrounding tissue with resultant high recurrent rate. Radiologic localization, especially CT scan study, is essential for surgical mapping. 9 cases of desmoid tumor from VGH Taipei and Taichung were reported. Findings of plain film include: soft tissue mass in 5 cases, associated bony change in 4 cases (pressure erosion 3 cases, periosteal thickening 1 case); 2 cases of iso-and hypo-dense lesion (compared with attenuation value of normal muscle tissue) is seen respectively in pre-contrast CT scan, all show picture of contrast enhancement, another 2 cases show hyperdense and mixed hyper-, hypodense area in which post-contrast CT scan were performed only; angiography were performed in 4 cases, which show a hypervascular mass with variable vascularity, without evidence of malignant vascular pattern (including tumor vessel, AV shunting, encasement, or early venous drainage). Recurrence were noted in 5 cases. CT scan study is the best choice of radiologic modality for pre-operative evaluation.
