Key result
Conservative medical management resolves hemoptysis from left-sided PAPVC with no recurrence at 1 year.
Why the study?
Partial anomalous pulmonary venous connection can present with hemoptysis, but such presentations are rare and require detailed imaging for diagnosis.
Case Report (n=1)
Vascular anomalies such as partial anomalous pulmonary venous connection (PAPVC) should be considered in the differential diagnosis of hemoptysis, as they can cause varix-like endobronchial lesions due to localized venous hypertension.

May support conservative management of hemoptysis in left-sided PAPVC; hypothesis-generating and requires validation in larger cohorts.
A 20-year-old man presented with recurrent hemoptysis.Chest CT revealed bilateral ground-glass opacities, predominantly in the right lower lobe (Picture A).

Takechi et al. (2026) conducted a case report in Partial Anomalous Pulmonary Venous Connection (PAPVC) (n=1). Conservative management (antibiotics and hemostatics) was evaluated on Recurrence of hemoptysis. Conservative management with antibiotics and hemostatics successfully treated hemoptysis secondary to left-sided partial anomalous pulmonary venous connection, with no recurrence at the one-year follow-up.
