| 目的 探讨小儿腹盆腔横纹肌肉瘤的CT表现特征
。方法 对12例经手术病理证实的
腹盆腔横纹肌肉瘤的起源、形态、大小和组织学类型进行回顾性分析。结果
全部横纹肌肉瘤CT增强前后均表现为边界清楚的软组织肿块,平扫肿块密度基本均匀,增强
后肿瘤周边区明显强化,内部强化不均。结论 腹盆腔横纹肌肉瘤好发于
膀胱、前列腺和腹膜后及肝内外胆道,肿瘤无包膜,边界清楚,肿瘤的内部常发生变性坏死
,增强后肿瘤的周边部分强化比内部明显。 |

| Purpose To explore CT features of abdominal and p
elvic rhabdomyosa
rcomas in children. Methods The origin,morphology,size,and h
istological type of 12 pediatric patients with abdominal and pelvic rhabdomyosarcomas were analy
zed retrospectively. Results The margins and densities of all tumors were well-defined an
d homogenous on plain
CT scans.After administration of contrast media,the peripheral portions of les
ions were strikingly enhanced and central portions enhanced heterogeneously. Conclusion The urinary bladder,prostate,retroperitoneum,vagin
al and extrahepati
c bile tracts are the commonest sites of abdominal and pelvic rhabdomyosarco
mas,which are well-circumscribed,but not encapsulated,and with various necrosis. |
