INTERSTITIAL DISEASE
Imagine that the lungs are like a honeycomb of tissue paper. Interstitial disease is a process (i.e. infection, inflammation, cancer) that affects the tissue paper, but does not involve the air spaces within the honeycomb.
INTERSTITIAL EDEMA
Intermediate stage of pulmonary edema. Fluid accumulates in the “tissue” part of the lungs. Imagine that the lungs are like a honeycomb of tissue paper. In interstitial edema, the tissue paper is soaked with fluid, but the spaces within the honeycomb are still filled with air. In advanced pulmonary edema, the air spaces within the honeycomb starts filling up with fluid. Please look at “pulmonary edema” for a slightly different description that may help you understand this better.
INTERSTITIAL THICKENING
Imagine that the lungs are like a honeycomb of tissue paper. With interstitial thickening, the tissue paper becomes thicker (i.e. when soaked with fluid). This can be detected on a chest x-ray.
INTERTROCHANTERIC
