摘要
目的:探讨免疫抑制状态下肝脏真菌感染的临床和CT表现及CT诊断价值。方法:9例经临床和/或病理证实的免疫抑制状态下肝脏真菌感染的患者,采用16层CT机行平扫及3期增强扫描。9例患者经抗真菌治疗1～3个月后复查,肝、脾病灶体积缩小,病灶数量减少或完全消失。结果:9例中7例CT表现为肝内多发类圆形低密度影,2例肝内弥漫分布小结节状低密度影,直径0.4～4.8cm,部分病灶边界清楚,增强扫描后病灶无强化或呈轻度～中度环形强化;其中2例可见脾内多发低密度影,强化方式与肝内病灶相同。结论:CT检查能很好显示肝真菌感染,并能对抗真菌治疗后疗效进行评价。
Objective：To study the CT findings and clinical manifestations of liver fungal infection in immuno-compro raised patients. Methods：9 immuno-compromised patients with clinical and/or pathology proved hepatic fungal infection had CT examinations,including precontrast, arterial, portal as well as delayed phase after contrast enhancement. All of these 9 patients had follow up CT 1-3 months after anti-fungal therapy, showing disappearance, shrinkage or lessening of the liver and spleen lesions. Results ： Of the 9 patients,multiple round shaped, hypo-attenuated lesions were showed in 7 patients, diffuse small hypo-attenuated nodular lesions in 2 patients. The diameter of these lesions ranges from 0.4 to 4.8cm, part of them showed well-defined margin. After contrast media administration, no or mild to moderate ring-like enhancement were assessed. Two patients had involvement of spleen with the enhanced pattern similar to that of liver. Conclusion： Liver fungal infection in immuno compromised patients could be clearly displayed on CT images,the efficacy of anti-fungal therapy could also be well evaluated.
