Bilateral choroidal mass as an initial manifestation of lung cancer

DOI: 10.37039/1982.8551.20250087

ABSTRACT

Choroidal metastasis is the most common intraocular malignancy. However, bilateral involvement remains exceptionally rare. We describe a case of a 57-year-old patient with no comorbidity who presented with progressive decrease in visual acuity of both eyes for 5 months duration. Fundus examination of both eyes revealed choroidal masses in the posterior pole with serous retinal detachment. She did not exhibit any respiratory symptoms, and systemic examinations were normal. Systemic investigation including computed tomography thorax revealed patient had lung tumour with HPE of the biopsy of regional lymph node confirming it to be adenocarcinoma. The patient received 12 cycles of chemotherapy and oral tyrosine kinase inhibitor. At 4 weeks, visual acuity improved and fundus showed shrinkage of choroidal mass. Even though bilateral choroidal metastasis is rare, any choroidal lesion should be taken as secondary spread until and unless proven otherwise.
