The case is presented of 70-year-old man with a history of chronic obstructive pulmonary disease and steroids in short courses for exacerbation of his disease. He had acute onset of cough with purulent sputum associated with progressive dyspnea that progressed to acute respiratory failure. It was considered to be secondary to severe community-acquired pneumonia due to the need for invasive mechanical ventilation and vasopressor support. A bronchoalveolar lavage was performed that showed filariform larvae of Strongyloides stercoralis, with parasitic pneumonia and hyperinfection syndrome being diagnosed.
