Rhabdomyosarcoma is a diagnostic and therapeutic problem in the management of pediatric tumors, representing the most common malignant orbital tumor of childhood. In this discussion of the diagnosis of rhabdomyosarcoma, the role of CT is detailed through the case reports and the radiographs presented. CT can accurately define the anatomic location of the orbital mass, the involvement of various intraorbital structures, and the extension of the pathologic process into the periorbital regions such as sinuses, nasal cavity, and intracranial compartment. Thin-needle aspiration biopsies can be done under CT guidance without complications as well as follow-up monitoring of tumor regression following therapy.
横纹肌肉瘤是儿童肿瘤治疗中的一个诊断和治疗难题，是儿童最常见的眼眶恶性肿瘤。在本次关于横纹肌肉瘤诊断的讨论中，通过病例报告和所展示的X线片详细阐述了CT的作用。CT能够准确界定眼眶肿物的解剖位置、眶内各结构的受累情况以及病理过程向眶周区域如鼻窦、鼻腔和颅内腔隙的扩展。细针穿刺活检可在CT引导下进行，不会出现并发症，还可用于治疗后肿瘤消退情况的随访监测。
