Article Figures & Data
Figures
- Fig. 1.
Chest radiograph. The chest radiograph (posterior-anterior, left) from the day of admission shows bibasilar peripheral hazy opacities in the middle and lower lobes.
- Fig. 2.
Chest computed tomogram. An image from the tomography pulmonary angiogram taken just inferior to the carina shows ground glass opacities, as well as prominent septal lines at the dependent pleural edge (arrowheads). The asterisk marks the site where the biopsy would be taken. No abnormalities are visible on the mediastinal window.
- Fig. 3.
Tissue biopsy with hematoxylin and eosin stain. Hyaline material is present in multiple small pulmonary arteries in the tissue biopsy obtained 4 months after the initial hospitalization (hematoxylin and eosin staining, high power).
- Fig. 4.
Dilated lymphatic vessels at the lung periphery. The lymphatic vessels (arrow) draining to the pleural surface are dilated (hematoxylin and eosin stain, low power).
- Fig. 5.
Lung biopsy stained for fibrin and hyaluronic acid (HA). Fibrin colocalized with HA in multiple small pulmonary arteries appears yellow; HA is identified by hyaluronan binding protein.5
