Case Report: Orbital metastasis as the presenting feature of lung cancer

Orbital metastasis from lung cancer as an initial presenting symptom is a rare entity, which may paradoxically delay the diagnosis and initiation of correct management, due to the confusion of it being primary orbital pathology. Herein we report a case of a 58 year old woman, who presented with painful orbital swelling along with diminution in her vision. The patient was initially thought to have a primary eye lesion; however chest X-ray was suggestive of a lung mass, which was confirmed by chest computed topography followed by ultrasound guided fine needle aspiration cytology. The patient was then referred to a cancer centre for further management. This case report aims to increase the knowledge about this metastasis as a probable cause of orbital symptoms in certain subsets of patients, so that correct therapeutic decisions may be made in the future.
