Almost half of the individuals with lung cancer will develop central nervous system metastases during the course of their disease. We report a case of an adult female presenting with progressive horizontal diplopia. Neurological examination showed horizontal diplopia in all directions of gaze. Eye movements were disconjugate when looking to the left; there was no abduction of the left eye. Bilateral vertical eye movements and right horizontal eye movements were intact. A cranial computed tomography (CT) scan revealed multiple lesions in both brain hemispheres suggestive of metastasis. An investigation to search suspected neoplasia of unknown origin was started. Chest CT scan with contrast revealed a large lesion, which was localized in the upper right lobe. An abdominal CT scan showed multiple lesions in the liver. A liver biopsy and the immunohistochemistry were diagnostic of adenocarcinoma of the lung. Three months after, the patient died due to septic shock following pneumonia.
