Abstract

The purpose of this two-part article is to review the cross-sectional imaging features of benign and malignant ampullary conditions with endoscopic and histopathologic correlation and to present the most common pitfalls in the evaluation of the ampulla. In this part, we will review the mesenchymal and secondary neoplasms of the ampulla, a vast array of benign ampullary conditions, causes of bulging papilla, and pitfalls. Familiarity with ampullary pathologic conditions and pitfalls, as well as the use of optimized MDCT and MRI techniques, may improve the diagnostic accuracy of radiologists facing ampullary abnormalities.

摘要

这篇分为两部分的文章旨在回顾壶腹良性和恶性病变的横断面成像特征，并与内镜及组织病理学表现进行相关性分析，同时介绍壶腹评估中最常见的陷阱。在本文的这一部分，我们将回顾壶腹的间叶性肿瘤和继发性肿瘤、一系列广泛的壶腹良性病变、乳头隆起的原因以及陷阱。熟悉壶腹病理状况和陷阱，以及运用优化的MDCT和MRI技术，可能会提高放射科医生面对壶腹异常时的诊断准确性。
