[Comparison between portography-CT and lipiodol-CT in the staging of hepatocellular carcinoma].
Eighteen patients (13 men and 5 women) with uni- and multifocal hepatocellular carcinomas (HCC) were examined. Mean patients age was 63.3 years (range: 47-74 years). All patients had alcoholic or posthepatitis cirrhosis; they were submitted to both CT during arterial portography (APCT) and Lipiodol-CT. The diagnosis of HCC was confirmed by fine-needle biopsy (FNB) in all cases. APCT and Lipiodol-CT results were compared for number, size and site of lesions-32 lesions in all. APCT demonstrated all the lesions: 9 of them were smaller than 2 cm, 14 ranged 2-5 cm and 9 were bigger than 5 cm; moreover, APCT demonstrated other lesions in 3/18 patients (16.6%) which had been missed by US, CT and angiography. Also Lipiodol-CT demonstrated all the 32 lesions and showed smaller lesions in 4/18 patients (22.2%); these nodules were smaller than 2 cm. Based on APCT results 11/18 patients (61.1%) were considered operable, vs. 7/18 patients (38.8%) based on Lipiodol-CT results. To conclude, both APCT and Lipiodol-CT are useful in the preoperative staging of HCC; Lipiodol-CT is preferable to APCT in the study of lesions smaller than 2 cm.
