摘要
目的探讨小儿骶尾部畸胎瘤的MR表现,评价MR的诊断价值。方法对15例经MR检查的患儿,进行回顾性分析。结果其中2例患儿肿瘤位于臀部生长.以囊性为主,呈圆形或椭圆形,内可见分隔,并可见脂肪信号,增强扫描可见囊壁及间隔强化;1例肿瘤全部位于盆腔内生长,呈囊实性混杂信号,增强可见实性部分、囊壁及间隔明显不均匀强化;12例可见肿瘤瘤体大部分位于盆腔内,小部分位于臀部生长,瘤内以囊性为主的囊实性混杂信号,增强扫描性实性部分囊壁及间隔有强化。结论MR检查能准确的显示小儿骶尾部畸胎瘤的位置和形态,有助于骶尾部畸胎瘤的诊断和良恶性的鉴别,并可以帮助临床选择合适的手术方式,对该病的诊断和治疗有重要意义。
Objective To discuss the MR manifestations of infantile teratoma in sacrococcygeal region and to evaluate the diagnostic value of MR. Methods Retrospective analysis was adopted on the MR results of 15 affected infants. Results The tumors in 2 cases located in hip, which is mainly cystic, circular or ellipse shaped with septum and fat signal can be seen. The wall and septum of the cysts can be reinforced in contrast enhanced imaging. The tumor in 1 case located total in pelvic cavity, presenting cystic and solitary mixed signal. The solitary part, cystic wall and septum can be obviously unequally reinforced in contrast enhanced imaging. In the rest 12 cases, the most parts of tumors located in pelvic cavity and small parts in hip presenting mainly cystic and partly solitary mixed signal. The solitary part, cystic wall and septum can be reinforced in contrast enhanced imaging. Conclusion MR can accurately display the location and shape of teratoma in sacrococcygeal region and is contribute to diagnose and differentiate benign or malignant lesion, in order to help clinician to choose operation method.
