CTICasesSevere Pulmonary Lymphangitic Carcinomatosis from Gastric Cancer
Imaging findings
On initial staging CT for gastric cancer, there is diffuse, nodular thickening of the interlobular septa and bronchovascular bundles throughout both lungs, with prominent, "shaggy," irregular pulmonary veins and involvement extending to the interlobar fissures; essentially no normal lung parenchyma remains.
Key takeaways
Nodular septal and peribronchovascular thickening with shaggy, irregular pulmonary veins -- rather than the smooth septal thickening of hydrostatic edema -- indicates pulmonary lymphangitic carcinomatosis; while historically most associated with gastric cancer, breast and lung cancer are now the most common primaries given the decline in gastric cancer incidence.
