Abstract

Pulmonary venous malformation is extremely rare. We present imaging and clinical findings of a 17-year-old male with multifocal subcutaneous venous malformations and multiple cystic lesions in the liver and spleen, suggestive of slow flow vascular malformation. In the right lung, chest radiography followed by chest CT demonstrated large tortuous pulmonary veins and cystic emphysematous changes. Tc99m-MAA (pertechnetate-labeled macroaggregated albumin) lung perfusion scan demonstrated only 3% of normal perfusion to the right lung, with no evidence of arteriovenous shunting. The child had diffuse intraparenchymal hemorrhage throughout the right lower and middle lobes and underwent resection. Pathology confirmed the diagnosis of venous malformation complicated with bleeding.
