[Ultrasonic aspect of neo-natal adrenal hematoma. 7 cases (author's transl)].

The authors report 7 cases of neo-natal adrenal hematoma diagnosed by ultrasound. A traumatic delivery was found in 4 cases. In 4 cases a flank mass was palpated. In 3 cases the adrenal hematoma was asymptomatic, discovered by echotomography. I.V.P. showed a typical appearance in only 1 case out of 5. The first ultrasonic examination was performed between day 5 and day 12. It showed a fluid filled mass in 5 cases and a predominantly fluid mass in 2 cases. Both sides were involved twice. The ultrasonic follow-up 8 days later always showed a decrease in size, in 1 cases calcifications appeared. The authors compare their results with those of the literature and discuss the differential diagnosis with neo-natal neuroblastoma.
