目的:探讨孤立型纤维性肿瘤的CT及病理学特点,提高对该疾病的诊断水平。方法:结合文献回顾性分析3例经手术病理证实的孤立型纤维性肿瘤的临床、CT及病理学资料。结果:孤立型纤维性肿瘤在临床上可无症状或因肿瘤压迫出现不典型症状。在CT上3例表现为实性肿块,增强后实性部分轻度强化或明显强化。SFT因有完整的包膜,故多为境界清楚的软组织密度肿瘤。结论:CT对SFT确诊价值有限,诊断必须结合既往病史、临床症状,确诊有赖于病理学与免疫组织化学诊断。
Objective: To investigate CT and pathological features of solitary fibrous tumors and to improve the diagnosis of this disease. Methods: The clinical, CT and pathological data of 3 isolated fibrous tumors confirmed by surgery and pathology were retrospectively analyzed. Results: Solitary fibrous tumors may be clinically asymptomatic or have atypical symptoms due to tumor compression. In CT 3 cases showed solid mass, enhanced solid part of the slight enhancement or significant enhancement. SFT due to a complete capsule, so mostly clear-cut soft tissue density tumors. Conclusion: The CT diagnosis of SFT is limited. Diagnosis must be combined with past medical history and clinical symptoms. Diagnosis depends on pathology and immunohistochemical diagnosis.
