Imaging findings
Chest CT demonstrates diffuse ground-glass opacities and denser consolidation with a prominent dependent distribution, accompanied by bilateral pleural effusions and a fine micronodular component. Bronchoalveolar lavage (BAL) and stool cultures recovered Strongyloides stercoralis larvae on a background of abundant red blood cells, reflecting diffuse alveolar hemorrhage.
Key takeaways
Strongyloides stercoralis can persist asymptomatically in the host for decades and cause life-threatening hyperinfection syndrome when the patient becomes immunocompromised, such as in advanced HIV/AIDS. The pulmonary phase of hyperinfection is associated with severe alveolar hemorrhage, which characteristically presents as dependent-predominant dense consolidations due to the gravity-dependent settling of blood.
