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.
Implication for health policy/practice/research/medical education: Focal orbital amyloidosis is a rare entity and little is known about imaging features on MRI. This article may help radiologists and clinicians to understand the imaging features of focal orbital amyloidosis on MRI and CT examinations.
