Abstract

Metastases to the orbit usually affect the intraorbital fat and bone than the extraocular muscles. Metastasis to the extracoular muscles commonly occurs unilaterally, and diffuse enlargement of the bilateral extraocular muscles due to metastasis is extremely rare. In this report, we will describe a case of diffuse metastasis to the bilateral extraocular muscles from nasal rhabdomyosarcoma masquerading as thyroid associated orbitopathy. We will also discuss about the MR imaging findings helpful for differential diagnosis from thyroid associated orbitopathy.

안와에 발생하는 전이암은 주로 안와 지방이나 뼈에 발생하며 한쪽에 국한되어 발생하고, 양쪽 외안근의 미만성비대 형태로 발생하는 경우는 매우 드물다. 저자들은 코에 생긴 횡문근육종 환자에서 치료 후 추적 관찰 중 발생한 안와의 전이암이 양쪽 외안근의 미만성 비대 형태로 발생하여 갑상선 안병증으로 오인되었던 1예를 보고하고 갑상선 안병증과 감별하는데 도움을 받을 수 있는 소견이 무엇인지에 대해 분석해 보고자 한다.
