Neurologic problems at high altitudes are well known. What is probably less emphasized are neurologic problems at altitude outside the setting of high-altitude cerebral edema. Because neurologic symptoms for these kinds of problems at high altitude are often transient, neuroradiologic scanning for these problems is usually not done or reported. Furthermore, diagnostic testing facilities may be unavailable in these remote high-altitude settings. A patient is described here with transient seizure and right-sided hemiparesis at high altitude with no preceding symptoms of acute mountain sickness. Computed tomography of the head was obtained in a hospital at lower altitude where the patient was taken promptly. The findings of the scan revealed probable focal cerebral edema in the left parietal lobe in keeping with his temporary right-sided weakness. Possible treatment modalities on the mountain for this problem are also discussed.
