Acute Pulmonary Edema as a Cardiovascular Manifestation of Pheochromocytoma

Figure 1. Chest radiograph demonstrating bilateral pulmonary infiltrates (case 1).

Figure 2. CT abdomen with contrast (case 1) - right-sided mixed semi-cystic mass (white arrows) lying inferior to liver and superior to but not arising from the right kidney. CT: computed tomography

Figure 3. ECG (case 1) - normal sinus rhythm, no evidence of ischemia. ECG: electrocardiogram

Figure 4. Hematoxylin and eosin stain of pheochromocytoma (case 1).

Figure 5. Synaptophysin immunohistochemistry staining of pheochromocytoma (case 1).

Figure 6. Chest radiograph demonstrating bilateral pulmonary infiltrates (case 2).

Figure 7. CT abdomen with contrast (case 2) - patchy crazy paving pattern opacification (arrows) seen on lung window at the lung bases. Crazy paving: ground-glass opacification with superimposed interlobular and intralobular septal thickening. CT: computed tomography

Figure 8. CT abdomen with contrast (case 2) - large right-sided cystic mass (arrow) seen below the liver but above the level of the kidney. CT: computed tomography

Figure 9. ECG (case 2) - sinus rhythm, Q-waves in V1-V3, subtle ST-depression in V4-V6, I, II, and aVF. ECG: electrocardiogram

Figure 11. Hematoxylin and eosin staining of pheochromocytoma showing nested growth (case 2).

Figure 12. S-100 protein immunohistochemistry stain of pheochromocytoma showing partially retained sustentacular cell network (case 2).
