Solid pseudopapillary neoplasm of the pancreas with liver metastasis initially misinterpreted as benign haemorrhagic cyst

ABSTRACT

Solid pseudopapillary neoplasm (SPN) of the pancreas is considered a low-malignant neoplasm witha good prognosis. However, 5% to 15% of patients with SPNs develop metastatic disease, mostcommonly in the liver. Metastatic hepatic malignancies that show pseudocystic features are rare.Here we describe the case of a middle-aged female with a cystic liver metastasis from SPN. To thebest of our knowledge, SPN with a single cystic liver metastasis has not been described, althoughthese tumours frequently undergo haemorrhagic-cystic degeneration. Thus, in these patients themarked cystic change could be misinterpreted as a benign lesion.
