Typical patterns of HAPE identified at CT scan of a young woman after her arrival in La Paz, Bolivia at 3500 m. Note the patchy and bilateral presentation of edema, areas where oxygen transport to pulmonary capillaries is severely compromised, generating low V’/Q’ areas responsible for the severe hypoxemia that can be encountered. The patient evolved favorably in 3 days and was able to fly back home on a scheduled flight, without sequalae.
