Pupillary sparing oculomotor palsy from metastatic carcinoma
Surgical Neurology
|April 1, 1983
Abstract:
A 60-year-old male with adenocarcinoma of the rectum had the acute onset of complete oculomotor palsy with pupillary sparing. Computed tomography scan and sellar tomograms demonstrated an ipsilateral parasellar mass with bony destruction. This case illustrates the need for a thorough search for metastatic disease in patients with third nerve palsy and known carcinoma.
Insights
A rare case of rectal cancer metastasizing to the brain caused a sudden oculomotor nerve palsy. This highlights the importance of searching for metastatic disease in cancer patients with third nerve palsy.
Area of Science:
- Neurology
- Oncology
- Ophthalmology
Background:
- Adenocarcinoma of the rectum is a common malignancy.
- Oculomotor nerve palsy can have various causes, including neoplastic and non-neoplastic etiologies.
- Pupillary sparing in oculomotor nerve palsy can suggest specific underlying pathologies, such as parasellar masses.
