CTICasesPulmonary Hemorrhage Associated with Antiphospholipid Antibody Syndrome
Imaging findings
High-resolution CT and chest radiography demonstrate multifocal, patchy ground-glass opacities distributed throughout both lungs, consistent with acute alveolar hemorrhage.
Key takeaways
Antiphospholipid antibody syndrome (APS) is a systemic autoimmune condition characterized by recurrent vascular thrombosis and pregnancy-related complications. Alveolar hemorrhage is a recognized, albeit relatively uncommon, pulmonary manifestation of both primary and secondary APS and is typically managed with corticosteroids and immunosuppressive therapy.
