【摘要】：目的探讨婴儿纤维性错构瘤(FHI)的CT、MRI表现并与病理对照。方法回顾性分析经手术病理证实的15例FHI患儿的临床、CT、MRI及病理学资料。结果 15例FHI中,单灶13例、双灶2例,共17个病灶,CT、MRI表现为皮下型、皮肤型和混合型病灶分别占58.82%(10/17)、17.65%(3/17)和23.53%(4/17)。皮下型、混合型病灶呈"云雾征"(包括"淡云征"及"浓云征"),其中"淡云征"病灶以成熟脂肪细胞为主,"浓云征"病灶的成熟脂肪细胞、致密纤维细胞及原始间叶细胞三相成分构成比较一致。皮肤型病灶呈"倒峦征",以原始间叶细胞为主。结论 FHI的CT、MRI表现复杂但也有一定的特点,可较好地反映其组织病理学特性。
[Abstract]:Objective to investigate the CT findings of infantile fibrous hamartoma (FHI) and compare them with pathology. Methods the clinical CT findings of 15 cases of FHI proved by operation and pathology were analyzed retrospectively. Results among the 15 cases of FHI, 13 cases had single focus and 2 cases had double focus. Cutaneous and mixed lesions accounted for 10 / 17 / 17 / 17.65 / 17 and 23.53 / 17 / 17, respectively. Subcutaneous type. The mixed lesions showed "cloud sign" (including "light cloud sign" and "dense cloud sign"), in which "light cloud sign" focus mainly consisted of mature adipocytes, and "dense cloud sign" showed mature adipocytes. The three-phase components of dense fibroblasts and primitive mesenchymal cells were consistent. The lesions of skin type were characterized by "inverted lube sign" and mainly consisted of primitive mesenchymal cells. Conclusion CT scan of FHI. MRI features are complex but also have certain characteristics, which can well reflect its histopathological characteristics.

【正文快照】： 软组织肿瘤为儿童常见肿瘤之一,在良性肿瘤中约占50%、恶性肿瘤中约占11%,其组织起源多样、种类繁多、病理分类分型复杂多变,良性、中间性和恶性尤其小儿中间型软组织肿瘤诊断与鉴别颇为不易[1-2]。婴儿纤维性错构瘤(fibrous　hamartoma　of　infancy,FHI)发病率低,但为早期
