Hormones are substances that serve as chemical communication between cells. They are unique biological molecules that affect multiple organ systems and play a key role in maintaining homoeostasis. In this role, they are usually produced from a single organ and have defined target organs. However, hormones can affect non-target organs as well. As such, biochemical and hormonal abnormalities can be associated with anatomic changes in multiple target as well as non-target organs. Hormone-related changes may take the form of an organ parenchymal abnormality, benign neoplasm, or even malignancy. Given the multifocal action of hormones, the observed imaging findings may be remote from the site of production, and may actually be multi-organ in nature. Anatomic findings related to hormone level abnormalities and/or laboratory biomarker changes may be identified with imaging. The purpose of this image-rich review is to sensitize radiologists to imaging findings in the abdomen and pelvis that may occur in the context of hormone abnormalities, focusing primarily on sex hormones and their influence on these organs.

腹部和骨盆成像发现与性激素异常有关。

激素是充当细胞之间化学通讯的物质。它们是独特的生物分子，会影响多个器官系统，并在维持同位性中起关键作用。在这种作用下，它们通常由单个器官产生并具有确定的靶器官。但是，激素也会影响非目标器官。这样，生化和激素异常可以与多个靶器官以及非靶器官的解剖学变化相关。与激素有关的变化可能采取器官实质异常，良性肿瘤甚至恶性肿瘤的形式。考虑到激素的多焦点作用，观察到的影像学发现可能远离生产部位，并且实际上可能是多器官的。与激素水平异常和/或实验室生物标志物变化有关的解剖学发现可通过成像来识别。这篇富含图像的综述的目的是使放射科医生对在激素异常情况下可能发生的腹部和骨盆成像结果敏感，主要关注性激素及其对这些器官的影响。
