Angiomatoid fibrous histiocytoma (AFH) are rare soft tissue mesenchymal neoplasms that commonly affect children and young adults. They are classified as "intermediate tumours of uncertain differentiation". We present a case of an 8-year-old child with a left thigh AFH and antecedent history of minor trauma showing perilesional oedema and enhancement at MRI, leading to an initial working diagnosis of infected haematoma that contributed to the challenge in reaching the final diagnosis. Although most of the imaging features of AFH previously described in the literature are demonstrated in this case, the presence of arterial vascular channels within the tumour and feeding branch from the left profunda femoris artery is unusual and to our knowledge the first to be published in the literature.
血管样纤维组织细胞瘤（AFH）是罕见的软组织间叶性肿瘤，常见于儿童和年轻人。它们被归类为“分化不确定的中间型肿瘤”。我们报告一例8岁儿童，左大腿患有AFH，有轻微外伤史，MRI显示病灶周围水肿及强化，最初的诊断考虑为感染性血肿，这给最终诊断带来了挑战。尽管本例显示了文献中先前描述的AFH的大多数影像学特征，但肿瘤内存在动脉血管通道以及来自左股深动脉的供血分支并不常见，据我们所知，这是首次在文献中发表。
