[An elderly case of lung cancer presenting with symptoms of orbital metastasis]

An 88-year-old woman was first referred to an eye clinic in mid-May 2000 because of limitation of ocular movement. A right orbital tumor was recognized on orbital CT scans and she was referred to our hospital. A chest X-ray film showed an abnormal mass in the right middle lung field, so she was admitted for further investigations. Adenocarcinoma was diagnosed by transbronchial lung biopsy. The right orbital tumor was thought to be a metastasis from the lung cancer. She received radiation therapy for the metastatic orbital tumor. However, two months after the onset of symptoms, she died due to progressive systemic metastasis. In summary, we report an elderly lung cancer patient whose initial symptoms were related to orbital metastasis.
