Critical asthma syndrome is the most severe consequence of an acute asthma exacerbation. Allergic bronchopulmonary aspergillosis is one of the most frequent pathologies that mimic critical asthma syndrome and is associated with a high mortality risk when timely diagnosis is not achieved in difficult-to-control asthmatic patients. We present the case of a 15-year-old male who was admitted to the intensive care unit with critical asthma signs and symptoms, where a diagnosis of allergic bronchopulmonary aspergillosis was made. He responded favorably with voriconazole and corticoids. In our context, the diagnosis of allergic bronchopulmonary aspergillosis should be considered in all patients with critical asthma or with a chronic lung disease that is difficult to control. Early diagnosis and treatment improve the quality of life and prognosis of patients.
