Primary tumours of the liver are uncommon in childhood. Of these, more than 
two-thirds are malignant. As such, benign hepatic tumours are often not 
considered in the differential diagnosis of a hepatic mass in childhood. We 
report a case of hepatic mesenchymal hamartoma, a rare benign tumour, in a 
10-month-old infant. This tumour is characterised by an admixture of ductal 
structures within a copious loose connective tissue stroma. Only approximately 
160 cases had been reported in the literature. Awareness of the ultrasound (U/S) 
and computed tomography (CT) features, although not diagnostic, is helpful in 
distinguishing it from the more common malignant tumours. A correct preoperative 
diagnosis is important as surgical excision is often curative.
