Abstract:
A 52-year-old man was admitted for detailed examination of a mass with extensive calcification in the tail of the pancreas by fluoro-deoxy glucose-positron emission tomography/computed tomography (FDG-PET/CT). Abdominal CT and magnetic resonance imaging (MRI) findings showed a calcified tumor 5 cm in diameter with a smooth surface. The tumor mainly showed calcification at it center and a partially solid element around it margin which was enhanced in the early phase. With no definiture preoperative diagnossi, we performed distal pancreatectomy and splenectomy. Pathological and immunohistochemical studies revealed a nonfunctioning islet cell tumor with calcification. A nonfunctioning islet cell tumor with central calcification formation as it grew to a maximum diameter of 7 cm is rare. When diagnosing pancreatic tumors it must be kept in mind that some nonfunctioning islet cell tumors of the pancreas can show nontypical features such as calcification formation.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
