摘要
目的探讨胚胎型横纹肌肉瘤(ERMS)的CT和MRI表现。方法回顾性分析经病理证实的26例ERMS的临床及影像学资料。结果 14例鼻部ERMS中,邻近骨质破坏11例,眼眶受累5例,翼腭窝及颅内侵犯各4例;5例腹盆腔及腹膜后ERMS中,3例包绕邻近大血管,2例腹膜种植转移;5例肌肉及肌间隙ERMS病变较局限,其中2例伴邻近骨质轻微破坏;1例ERMS位于左颌下腺区;1例ERMS为颅骨多发病灶。16例患者有区域淋巴结转移,5例呈环线状强化。结论 ERMS的临床及影像学表现缺乏特异性,对患者年龄、发生部位、强化方式、邻近骨质的破坏及区域淋巴结转移等进行综合分析有助于治疗前诊断。
Objective To investigate CT and MRI findings of the embryonal rhabdomyosarcoma （ERMS）. Methods Clinical data and CT or MR images of 26 patients with histologically proved ERMS were retrospectively reviewed. Results The nasal ERMS was found in 14 patients, including adjacent bone destruction （n= 11）, involvement of orbit （n= 5）, pterygopalatine fossa （n= 4） and intracranial （n= 4）. Among 5 patients of peritoneum and retroperitoneum ERMS, 3 showed adjacent blood vessel encasement, 2 showed peritoneum metastasis. All 5 muscle and intramuscular space ERMS were well circumscribed, 2 showed mild destruction of adjacent bone. Left submadibular gland was found in 1 patient and skull multiple lesions were found in 1 patient. Sixteen patients showed regional lymphadenopathy, 5 were grape-like enhanced after injection of contrast medium. Conclusion The clinical and imaging features of ERMS lack specificity. The accurate diagnosis correlates with aggregate analysis of the age, site, enhancing pattern, adjacent bone destruction, regional lymphadenopathy, and so on.
