Abstract

We report a case of a pulmonary venous malformation in a 4-year-old boy who presented with recurrent pneumonia. A radiograph revealed a right infrahilar mass and a hyperlucent right lung. Computed tomography (CT) demonstrated a mass containing intensely enhancing areas and multiple phleboliths located in the right lower lobe and encasing the right bronchus and right inferior pulmonary vein. Magnetic resonance imaging (MRI) precisely revealed the mass demarcation. A right lower lobectomy was performed and a pathological examination confirmed the diagnosis of a venous malformation. To the best of our knowledge, a venous malformation in pulmonary tissue has not been reported in the English literature. Herein, we report a case of a pulmonary venous malformation, with the radiograph, CT, MRI, and blood pool scan findings, along with its pathologic correlation.

  Fig. 1 4-year-old boy with repeated episodes of pneumonia. A. Chest radiograph shows right lower lobe mass (arrow), unilateral hyperlucency, and decreased volume of right lung. B. Precontrast CT scan shows multiple phleboliths within mass (arrows). C. After injection of contrast material, anterior portion of mass was intensely enhanced (arrow). D. Mass caused luminal narrowing of right lower lobar bronchus (arrowhead) and right inferior pulmonary vein (arrow). E. T2-weighted coronal images show high-intensity mass encasing pulmonary artery (large arrow), bronchus (small arrow), and pulmonary vein (arrowhead). F. Whole body blood pool scintigraphy demonstrates intense blood pooling at right infrahilar region (arrow), similar to that of heart and multifocal faint blood poolings in right upper and left lower extremities (arrowheads). G. Microscopic image demonstrates typical erythrocyte-filled vascular spaces lined with flattened mature nonhypercellular endothelium without elastic tissue in wall of vessels (Elastic Stain, ×10).
