Abstract
Eighty-two cases of hepatic amoebiasis were diagnosed and treated at the University of Nigeria Teaching Hospital during a 4-year period. Typical or classical features were observed in 75 (91.4%) of the cases while the remaining seven presented atypically or unusually. These were obstructive jaundice (three cases), coma (two cases) and pyrexia of unknown origin (two cases). All the cases had positive gel diffusion precipitation test for amoebic antibodies, and in all but one there was demonstration of an abscess cavity. In the three cases of obstructive jaundice, the abscess cavities were located close to the hilum and compressed the main bile duct. There was no mortality recorded especially in the jaundiced cases despite the grave prognosis associated with jaundice in hepatic amoebiasis. This study demonstrates the need to consider hepatic amoebiasis in an area when patients present with either obstructive jaundice, coma or pyrexia of unknown origin and to do ultrasonography as an initial investigation in such patients.
