We present a 57-year-old man with Zollinger-Ellison syndrome who had undergone total gastrectomy 12 years previously. At that time, a cystic mass in the left lobe of the liver was palpated but was not removed. The patient currently had high serum gastrin levels. Abdominal ultrasound, CT and MR images showed a well defined liver mass with solid and cystic components. The lesion was resected and a primary hepatic carcinoid tumour was diagnosed. Post-operatively, serum gastrin levels were normal. A primary liver carcinoid may appear as multicystic liver mass with solid components. Careful exclusion of a primary tumour elsewhere is required to establish the diagnosis of this rare entity.
