Metastatic Lung Cancer Masquerading as Endophthalmitis.

A 41-year-old man presented to the emergency department with a painful and red left eye associated with chronic vision loss. He had a history of homelessness and polysubstance abuse including intravenous drug use. Fundus examination revealed several cream-colored lesions encroaching on the macula of the right eye, and a total retinal detachment with secondary neovascular glaucoma in the left eye. Further work-up with imaging and endobronchial ultrasound-guided fine needle aspiration revealed stage IV epidermal growth factor receptor (EGFR) mu- tant (L858R) lung adenocarcinoma with brain, bone, adrenal, lymph node and bilateral choroid- al metastases. Herein we present a case of metastatic lung cancer masquerading as endophthalmitis.
