Metastatic carcinoid tumour presenting as a hepatic pseudocyst

Although hepatic metastases from gastrointestinal carcinoid tumours are common, cyst formation in these secondaries is only rarely reported. The present report describes a patient presenting with a cystic mass in his liver due to a metastasis from a carcinoid tumour. As prolonged survival is possible in patient with a carcinoid tumour, even in the presence of liver metastases, cyst formation in a carcinoid secondary should be considered when a patient is found to have a cystic mass in the liver.
