[Irregular hepatic steatosis. Ultrasonic and computed x-ray tomographic aspects].

A 39-year-old moderately obese and alcoholic man complained of abdominal pain and nausea. An ultrasound examination of the liver showed large hyperechoic areas surrounding a limited pseudotumorous zone of relatively decreased echogenicity. CT scan showed a decreased density (35 UH) in the hyperechoic areas, suggesting fatty liver which was confirmed histologically; conversely, the hypoechoic area appeared normal on CT scan. Six months later, after reduction of caloric intake and cessation of alcohol ingestion, ultrasound examination and CT scan of the liver were normal.
