摘要
目的探讨动态增强CT扫描对肝脏局灶性结节增生(FNH)的诊断价值。方法对19例FNH行三期动态增强CT扫描的影像资料进行回顾性分析。结果 19例均为单发病灶,3个病灶直径小于30mm,16个病灶直径31~73mm。动脉期17个病灶呈明显均匀强化,2个病灶呈略不均匀强化,14个病灶周围或内部见增粗迂曲肝动脉。门脉期9个病灶呈等密度,7个病灶呈略高密度,3个病灶呈略低密度。平衡期10个病灶呈等密度,5个病灶呈略高密度,4个病灶呈略低密度。11个病灶内可见瘢痕状低密度区。结论 CT扫描肝内病灶动脉期呈明显均匀强化,病灶内或病灶周边可能显示增粗迂曲肝动脉;门脉期、平衡期病灶呈等、略低或略高密度;病灶内可能含有瘢痕状低密度区,以上征象的出现高度提示FNH的诊断。
Objective To evaluate the value of dynamic enhanced CT in diagnosing focal nodular hyperplasia (FNH) of liver. Methods A retrospective analysis was done for data in 19 patients with FNH underwent triphase dynamic enhanced CT scans. Results All the 19 patients had a single lesion, of which, three were less than 30 mm in diameter, 16 ranged 31- 73 mm. In the arterial phase, 17 lesions demonstrated homogeneous enrichment, two showed slightly uneven enrichment, and thickened and circuitous hepatic arteries could be seen inside or around 14 lesions; In portal venous phase, nine showed isodense, seven showed slightly-high density, and three with low density; In balanced phase, 10 appeared as isodense, five as slightly-high density, and four as low density. A scar-form low density area could be seen inside of the 11 fool. Conclusion In CT scanning, the lesions of liver show well-distributed enrichment in arterial phase, thickened and circuitous hepatic arteries could be seen inside or around the lesions. In portal venous phase and balanced phase, the lesions show isodense, slightly-high density or low density, and scar-form low density area is likely to be found in the lesions as well. All the above signs are strongly suggestive of the diagnosis of FNH.
