Myopericytoma is a rare perivascular tumor commonly arising in the superficial soft tissue and subcutaneous tissue of the distal extremities. We report the first case of myopericytoma occurring in the breast, focusing on the imaging and histopathological characteristics of the tumor. From an imaging perspective, myopericytoma presents a well-circumscribed, marked hypervascularity, and intense enhancement after injection of contrast material. Imaging examinations, such as ultrasonography and magnetic resonance imaging, can contribute to the detection of tumor invasion to adjacent structures or distant metastases, and provide evidence for a treatment plan.
肌周细胞瘤是一种罕见的血管周围肿瘤，通常发生于四肢远端的浅表软组织和皮下组织。我们报告了首例发生于乳腺的肌周细胞瘤，重点关注该肿瘤的影像学和组织病理学特征。从影像学角度来看，肌周细胞瘤表现为边界清晰、明显的血管丰富以及注射造影剂后强化明显。超声和磁共振成像等影像学检查有助于检测肿瘤对相邻结构的侵犯或远处转移，并为治疗方案提供依据。
