Well-Differentiated Pancreatic Neuroendocrine Tumor with Solitary Hepatic Metastasis Presenting as a Benign Cystic Mass: A Case Report

초록

Pancreatic neuroendocrine tumors and their hepatic metastases have an inconsistent appearance with only a small percentage of lesions appearing as cystic masses in computed tomography (CT) and magnetic resonance imaging (MRI). Therefore, they can be mistaken as benign or infectious lesions, which can lead to a false diagnosis with delayed or inadequate treatment. We reported a patient with upper abdominal pain that lasted for several months, caused by a huge cystic neuroendocrine carcinoma of the liver. This was mistakenly interpreted as a complicated or hydatid cyst, and the findings in the CT and MRI was presented.
