Cystic neoplasms of the pancreas: A clinical and radiological study of eight cases

Abstract

Four patients with benign serous cystadenoma, one with mucinous cystadenoma, and three with mucinous cystadenocarcinoma treated in the university hospital of Göttingen between 1985 and 1988 were investigated. The main initial symptoms of these cystic tumors were abdominal pain (7/8), weight loss (3/8), maldigestion (3/8), and palpable abdominal mass (3/8), while laboratory investigations revealed nonspecific alterations (elevated ESR, mild hypochromic anemia). CA 19-9 was elevated in two patients, one of whom had cystadenocarcinoma; CEA also was elevated in this patient only. In all cases size, localization, and cystic character of the tumors were shown clearly by sonography and computed tomography; fine needle biopsy helped to distinguish between serous and mucinous cystadenoma in four of six cases. Because of their malignant potential, total extirpation of mucinous cystic tumors is the treatment of choice, while serous cystadenomas are benign and therefore may be treated conservatively in uncomplicated cases or high-risk patients.
