160 Non-Neoplastic Lymphadenopathy: Mediastinal Fibrosis

CASE 160


image Clinical Presentation


28-year-old woman with chest pain and dyspnea


image Radiologic Findings


PA chest radiograph (Fig. 160.1) demonstrates decreased right lung volume, right hilar fullness, and paucity of right lower lobe vasculature. Axial and coronal contrast-enhanced chest CT (mediastinal window) (Figs. 160.2, 160.3) shows a right hilar soft-tissue mass with multifocal internal calcifications that obliterates the lumen of the right pulmonary artery. Contrast-enhanced chest CT (lung window) (Fig. 160.4) reveals attenuation in the caliber of the right lower lobe pulmonary arteries and right lower lobe peripheral ground glass opacity.
