Conclusion
PE case reports are increasingly rising with the difficult to notice among HAPE patients given their presentation similarities. A high index of suspicion based on clinical examination and investigations should prompt a clinician to include or exclude it. Early diagnosis is key especially if a patient is not improving despite the measures taken for managing HAPE. However, further studies are needed to understand more on the occurrence of PE in high altitudes and the possible development of a screening tool that could assist in early diagnosis to prevent development of serious complications.
