摘　　要：目的探讨肝脏肉芽肿的早期和晚期CT表现并与病理对照分析,进一步提高对本病的认识和诊断的准确性。方法对31例经手术病理证实的肝脏肉芽肿进行回顾性分析,全部行上腹CT平扫、动态增强扫描。结果肉芽肿早期病灶,平扫为边缘模糊的低密度灶,形态可为圆形、花瓣型、索条形,增强动脉期不均匀强化或明显强化,持续至门脉期、延迟期有逐渐增加的趋势。31例肝脏肉芽肿共35个病灶,其中9个为早期肉芽肿。纤维化期平扫示边界清晰的低密度灶,形态为圆形、卵原形等,增强无明显强化或边缘环状强化,31例肝脏肉芽肿共35个病灶,26个为纤维化期病灶。结论肝脏肉芽肿的多期CT表现可以反映其所处的病理时期,可以与肝脏的其它肿物鉴别。Objective To investigate the early and late stages of liver granuloma CT and pathologic analysis of performance and further enhance the awareness of this disease and diagnostic accuracy. Methods 31 patients with pathologically proved liver granuloma were analyzed retrospectively, all OK abdominal CT scan, dynamic contrast - enhanced scans. Results Early granuloma lesions, plain lowdensity lesions at risk ambiguity, shape can be round, petal type, cord bar, enhanced arterial phase enhancement or uneven obviously enhanced and sustained to the portal phase, latency period is gradually increasing trend. 31 cases of liver granuloma lesions were 35, including nine of early granulonm. The fibrotie stage of the boundary scan clear low - density lesions, morphology round, egg prototype so as to, enhance the edge of no significant enhancement or rim enhancement,31 cases of liver granulomas were 35 lesions,26 for the fibrotic stage lesions. Conclusion Of the muhi - phase CT hepatic granuloma may reflect their performance in the period in which the pathology can be identified with the liver and other tumor.
