Abstract

Focal orbital amyloidosis is a rare entity and little is known about its magnetic resonance imaging (MRI) features. In this case report, imaging features of a case of focal orbital amyloidosis presenting as a mass have been documented together with its histopathological findings. On MRI, a well-defined mass was seen as isointense with rectus muscle on T1-weighted images and heterogeneously hypointense on T2-weighted images. Punctuate calcifications were observed on the computerized tomography (CT) examination.

摘要

局限性眼眶淀粉样变性是一种罕见的病症，人们对其磁共振成像（MRI）特征知之甚少。在本病例报告中，记录了一例表现为肿块的局限性眼眶淀粉样变性的影像学特征及其组织病理学结果。在MRI上，一个边界清晰的肿块在T1加权图像上与眼直肌呈等信号，在T2加权图像上呈不均匀低信号。在计算机断层扫描（CT）检查中观察到点状钙化。
