Abstract
目的 回顾分析慢性血吸虫病腹部CT表现与病理结果,以求进一步提高对其的诊断准确性. 方法 103例患者进行腹部CT平扫,81例行CT增强扫描;全部病例均获得手术标本及作病理切片,并注意切片方向与CT扫描层面相近的平面进行. 结果 CT显示肝硬化84例,以肝脏右叶改变最重;肝内不同形态钙化71例,以分隔状钙化最多;肝癌12例;脾脏增大78例,脾脏钙化13例;结肠壁增厚27例,以降、乙状结肠及直肠增厚居多;结肠壁钙化31例,其中全结肠弥漫性钙化5例;结肠癌9例.病理观察肝内不同程度纤维化并形成假小叶,纤维增生间隔及假小叶内均可见虫卵及钙化;结肠黏膜下及区域淋巴结内可见虫卵及钙化.结肠壁纤维组织及黏膜组织增生明显;脾内可见纤维增生及钙化,但未见虫卵. 结论慢性血吸虫病对腹部脏器的损伤以肝脏及结肠为重,CT的病理性改变也相对明显,而脾脏改变大多是肝硬化的伴随变化.CT腹部扫描检查是慢性血吸虫病脏器病理损害和程度的重要影像诊断方法。
