Abstract
BackgroundReduction in visual acuity combined with blurred vision is rarely the first sign of lung cancer and very few cases have been announced globally.Case presentationA case of a 46-year-old man who admitted with blurred vision is presented. His medical history, apart from a mild gastritis under treatment was negative. Ocular examination revealed a decrease in visual acuity due to a choroidal tumor. Further image body scans demonstrated a right lung lesion with dissemination to other organs. Diagnosis of a non-small cell lung cancer established after a VATS biopsy carried out.ConclusionBlurred vision due to choroidal metastasis as the primary symptom of lung cancer is very uncommon. A great index of suspicion is essential when a choroidal lesion appears.
Highlights
Reduction in visual acuity combined with blurred vision is rarely the first sign of lung cancer and very few cases have been announced globally.Case presentation: A case of a 46-year-old man who admitted with blurred vision is presented
The incidence of ocular metastases from lung cancer is reported to be 2-7% according to the international literature [1,2]
It is generally considered that these kind of metastatic lesions occur at the final stage of the disease, where the mean survival is not expected to be more than 6 months and the majority of the patients already suffer from the typical lung cancer symptoms [6]
Summary
The incidence of ocular metastases from lung cancer is reported to be 2-7% according to the international literature [1,2]. Case presentation A 46-year-old man noticed, three months ago, that for the past two weeks his left eye suffered from reduction in vision with a concomitant blurredness. He had no medical history apart from a mild gastritis under treatment. A transthoracic needle biopsy of the right upper lobe lung mass could not provide enough material to establish an accurate histopathological diagnosis. The patient experienced a Video Assisted Thoracic Surgical biopsy and the diagnosis of a low-grade squamous cell carcinoma was established (Fig 3).
