Sonographic diagnosis of congenital tuberculosis: an experience with four cases.

Abdominal sonography of four infants with pyrexia and hepatomegaly demonstrated multiple hypoechoeic hepatic and splenic foci, guided biopsies of which showed caseating granulomas with acid-fast bacilli. Evidence of tuberculosis in maternal endometrium and its exclusion in the contacts further confirmed a diagnosis of congenital tuberculosis. Clinical suspicion supplemented by careful sonography facilitated early detection and antemortem diagnosis of this potentially fatal disease.
