The presenting signs and symptoms of pulmonary veno-occlusive disease (PVOD) lack specificity. Most of the symptoms mimic other pulmonary and cardiac entities. The most common presenting symptoms are exertional dyspnea, fatigue, and cough. Sometimes, a respiratory tract infection–like illness may be identifiable preceding the diagnosis. Chronic cough (either productive or nonproductive) is present in some individuals.

In the later stages of PVOD, symptoms attributable to right ventricular failure, including chest pain and dizziness with exertion, abdominal pressure and tenderness secondary to hepatic congestion, and exertional syncope, may be noted. Hemoptysis with diffuse alveolar hemorrhage has been reported as a presentation. [32]

The suggestion of occult alveolar hemorrhage in bronchoalveolar lavage findings, however, is not uncommon. [33] Postural dyspnea or orthopnea may be reported by patients with PVOD but these findings are unusual among patients with primary pulmonary hypertension.
