Antiphospholipid syndrome (APS) is an entity characterized by thrombotic phenomena (arterial and/or venous), fetal losses, and persistent increase in the serum level of antiphospholipid antibodies.

The most common pulmonary complications of APS are pulmonary thromboembolism and thromboembolic pulmonary hypertension. Alveolar hemorrhage is a rare, potentially life-threatening manifestation (catastrophic APS). The diagnosis is confirmed when more than 20 % of the macrophages in a sample taken by bronchoalveolar lavage (BAL) are positive for hemosiderin. Radiographic findings most commonly show ground-glass opacities or consolidations that are usually diffuse, bilateral, more central than peripheral. The DLCO is another diagnostic method, with values above 120 % of the predicted value.

We present the case of a patient with APS with a history of deep vein thrombosis (DVT) and anticoagulated pulmonary thromboembolism (PTE), who was admitted with a diag nosis of alveolar hemorrhage (AH).

Palabras clave : Primary antiphospholipid syndrome; Alveolar hemorrhage.
