Presentation
Middle-aged woman presented with long standing vague abdominal pains.
Patient Data
Axial and coronal contrast-enhanced CT scan shows a large cystic multiloculated mass located on the body of pancreas. The mass has extensive wall calcifications, enhancing solid parts and enhancing septa.
A turbid bloody fluid was aspirated from the cyst, and sent for evaluation for CA 19-9 and hydatid scolices, both of which came back negative.
Case Discussion
According to the presence of a macrocytic lesion in the body of pancreas with wall calcifications, in a middle-aged woman, our first consideration was mucinous cystic neoplasm. The patient reported the presence of the same lesion since 20 years ago that was not consistent with MCN. As we live in an endemic place for hydatid, my next differential diagnosis was hydatid disease. The patient underwent core needle biopsy. To our surprise, the histologic diagnosis was neuroendocrine tumor.
