Abstract
BACKGROUND: Nodular regenerative hyperplasia (NRH) of the liver is a multi-acinar regenerative nodular lesion in a non-cirrhotic liver. It is a rare entity, especially in children, and remains of unknown aetiology. OBJECTIVE: NRH is often seen in association with other diseases or drug intake. In half of patients it is complicated by portal hypertension. Radiologically, its nodular appearance may look like neoplasia. RESULTS: We report a case of NRH with enormous hepatomegaly and multiple huge nodules. CONCLUSION: We wish to emphasise the importance of open wedge biopsy to establish diagnosis, since the prognosis of NRH in the absence of portal hypertension is good. Complications such as rupture of a nodule are rare.
