High-altitude Cerebral Edema and High-altitude Pulmonary Edema Diagnosed in the Desert: A Case Report
1Desert Regional Medical Center, Palm Springs, California.
Introduction:
Acute mountain sickness, high-altitude pulmonary edema (HAPE), and high-altitude cerebral edema (HACE) are a spectrum of high-altitude conditions, with HACE being the most life-threatening. Most cases develop at altitudes of greater than 4,000 meters (∼13,000 feet) above sea level and after one to five days.
Case Report:
A previously healthy 46-year-old female presented to the emergency department with ataxia, altered mental status, and vomiting that developed after rapidly ascending to ∼2,400 meters (∼7,800 feet) above sea level. She was treated for HACE and HAPE with resolution of her symptoms within 24 hours.
Conclusion:
High-altitude pulmonary edema and HACE can develop rapidly and at moderate altitudes. Expeditious recognition and treatment is imperative to avoid life-threatening complications.
