This case report highlights a unique radiological presentation of angiomatoid fibrous histiocytoma featuring arterial vascular channels and a feeding branch, which can complicate diagnosis.
Unusual MRI vascularity may complicate AFH diagnosis; leaves open the imaging spectrum pending larger series.
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.
