Dirofilariasis is a helminthic zoonosis occurring in many parts of the world. We report the findings in a 61-year-old woman who had painless right exophthalmos caused by orbital dirofilariasis. A vivid worm was embedded inside an inflammatory nodule in the right orbit. On T1-weighted MR images, the parasite was visible as a discrete, low-intensity, tubular signal in the center of the nodule surrounded by contrast-enhancing inflammatory tissue.
丝虫病是一种发生在世界许多地区的蠕虫性人畜共患病。我们报告了一名61岁女性的病例,她因眼眶丝虫病导致右侧无痛性眼球突出。一条鲜活的蠕虫嵌在右侧眼眶的炎性结节内。在T1加权磁共振图像上,寄生虫在结节中心表现为离散的、低强度的管状信号,周围是强化的炎性组织。
