A 66-year-old member from the United States developed acute symptoms of high-altitude cerebral edema (HACE) during an ascent of Kilimanjaro. After reaching Barafu Camp, he began experiencing severe headache, dizziness, shortness of breath and was unable to walk unaided. Given the signs of altitude-induced neurological impairment and the camp’s high elevation, Global Rescue approved a helicopter evacuation to a nearby hospital. The member was promptly evaluated and diagnosed with altitude sickness. He responded well to treatment and was discharged later that day. This case exemplifies the dangers of rapid altitude gain and the critical importance of recognizing HACE symptoms early. Timely aerial evacuation and supportive care allowed for a fast recovery and prevented potentially severe outcomes. The member later reported that his condition had improved and confirmed that no additional follow-up care was needed after discharge.
