Myopericytoma is a rare, usually benign soft tissue tumour that arises most commonly in the dermis and subcutaneous soft tissue of the lower extremities. In this article, we present an unusual case of myopericytoma occurring in the deep soft tissue around the knee that mimicked a neurogenic tumour. Myopericytoma can be confused with neurogenic tumour when located in deep soft tissue and adjacent to nerve bundles. Preoperative MRI and colour Doppler ultrasound may help differentiate myopericytoma from neurogenic tumour by revealing the hypervascular nature of the tumour.
肌周细胞瘤是一种罕见的、通常为良性的软组织肿瘤，最常见于下肢的真皮和皮下软组织。在本文中，我们报告了一例发生在膝关节周围深部软组织的不寻常的肌周细胞瘤病例，该病例酷似神经源性肿瘤。当肌周细胞瘤位于深部软组织且与神经束相邻时，可能会与神经源性肿瘤混淆。术前磁共振成像（MRI）和彩色多普勒超声通过显示肿瘤的高血管特性，可能有助于将肌周细胞瘤与神经源性肿瘤区分开来。
