Das mikrozystische seröse Zystadenom des Pankreas

Zusammenfassung

Mikrozystische seröse Zystadenome sind seltene zystische Neoplasien des Pankreas und mit sehr seltenen Ausnahmen benigne. Aufgrund ihrer typischen Morphologie (Honigwabenmuster, ausgeprägte septale Vaskularisation, zentrale Narbe) können sie im Regelfall durch abdominelle Sonografie, Endosonografie, Computertomografie oder Magnetresonanztomografie sicher diagnostiziert werden. Die Abgrenzung der selteneren oligozystischen serösen Zystadenome zu muzinösen Pankreasneoplasien ist dagegen schwierig. Seröse Zystadenome sind bevorzugt in Korpus und Cauda des Pankreas lokalisiert. Frauen sind etwa 3mal häufiger betroffen als Männer, das mittlere Erkrankungsalter liegt im 6. oder 7. Lebensjahrzehnt. Etwa die Hälfte der serösen Zystadenome sind zum Zeitpunkt der Diagnose asymptomatisch. Eine chirurgische Therapie ist nur bei Symptomen und bei großen Tumoren indiziert. 

Abstract

Serous microcystic cystadenoma is a rare cystic neoplasm of the pancreas, and in almost all cases it has a benign biological behavior. Due to its typical morphology (honeycombing, distinct septal vascularization, central scar) diagnosis by transabdominal ultrasound, endoscopic ultrasound, computed tomography or magnetic resonance imaging in most cases is not difficult. The infrequent oligocystic variant of serous cystadenoma may be difficult to distinguish from mucinous cystic neoplasms. Serous cystadenomas mostly are found in the body or tail of the pancreas, and are seen predominantly in female patients (f : m = 3 : 1) in the 6^th oder 7^th decade of life. Approximately half of all serous cystadenomas are asymptomatic at the time of presentation. Surgical treatment is indicated only in symptomatic patients and in the case of large tumors.
