        • Definitions

          • Diseases that characteristically compromise peribronchovascular interstitium
          • Peribronchovascular distribution often coexists with perilymphatic distribution given continuum of peribronchovascular lymphatic channels (e.g., sarcoidosis, lymphangitic carcinomatosis, silicosis, and bronchus-associated lymphoid tissue lymphoma or BALToma)
          • Predominant peribronchovascular involvement
            • Hydrostatic pulmonary edema
            • Organizing pneumonia
            • Kaposi sarcoma
            • Pulmonary interstitial emphysema
            • Interstitial pulmonary hemorrhage
