Abstract:
A 39-year-old man with a known diagnosis of lung adenocarcinoma developed intermittent double vision with right pupil dilatation. His symptoms eventually progressed to complete oculomotor nerve palsy on the right. Postmortem examinations revealed a metastasis of the adenocarcinoma involving the root of right oculomotor nerve.
Insights
Lung adenocarcinoma can metastasize to cranial nerves, causing oculomotor nerve palsy. This case highlights a rare presentation of lung cancer spreading to the nerves controlling eye movement.
Area of Science:
- Neurology
- Oncology
- Ophthalmology
Background:
- Lung adenocarcinoma is a common malignancy.
- Oculomotor nerve palsy can result from various neurological conditions.
Observation:
- A 39-year-old man with lung adenocarcinoma presented with diplopia and right pupil dilation.
- Symptoms progressed to complete right oculomotor nerve palsy.
Findings:
- Postmortem examination confirmed lung adenocarcinoma metastasis.
- The metastasis involved the root of the right oculomotor nerve.
Implications:
- This case underscores the potential for lung adenocarcinoma to metastasize to cranial nerves.
- Understanding rare metastatic patterns is crucial for diagnosis and treatment of lung cancer patients.
