97 Possible Causes for Alveolar Septa Thickened

  • Desquamative Interstitial Pneumonia

    […] accumulation of macrophages and thickening of alveolar septa: bilateral and symmetric (86%) 7 basal and peripheral (60%) patchy (20%) diffuse (20%) 4 Other frequent CT findings[] […] of alveolar septa Architecture is preserved No scarring or honeycomb change Fibroblastic foci rare Mild interstitial infiltrate of plasma cells and lymphocytes Lymphoid follicles[] Alveolar septa are slightly thickened. e) The cytoplasm of most macrophages contains an abundant dust-brown pigment.[]

  • Mycoplasma Fermentans

    The alveolar epithelial (type I) cells and type II pneumocytes are diffusely damaged. There is interstitial edema and thickened septa.[] An eosinophilic alveolar membrane may form, and the alveolar space may fill with foamy macrophages.[]

  • Hemangiomatosis

    […] medial hypertrophy Microscopic (histologic) images Images hosted on other servers: (A)small veins demonstrate marked myointimal thickening; adjacent alveolar septa are thickened[] […] of venules in lobular septa with some septal veins completely occluded, increased elastic fibers in venous media (highlighted with elastin stain); intimal fibrosis narrows[] […] pulmonary capillary hemangiomatosis; (B) CD31 highlights endothelial cell proliferation Pulmonary capillary hemangiomatosis Images hosted on Flickr: Cytology description Alveolar[]

  • Pulmonary Vascular Disorders

    Image of diffuse alveolar hemorrhage. Alveoli are filled with blood and hemosiderin-laden macrophages. The alveolar septa are thickened.[] Image of thickened alveolar septa with that comes with chronic congestion. What is a saddle embolus and why are they so lethal?[] Image of chronic congestion with hemosiderin-containing macrophages (heart failure cells) in alveoli and thickened alveolar septa.[]

  • Radiation Pneumonitis

    Intermediate phase (1-6 months): This is characterized by dose-dependent leakage of proteins into the alveolar space, thickening of the alveolar septa, and development of[] […] of the alveolar septa.[] Pulmonary fibrosis is the repair process that follows the acute inflammatory response and is characterized by progressive fibrosis of the alveolar septa thickened by bundles[]

  • Pleuropulmonary Blastoma

    […] with thickening of the alveolar septa and occupation of the lumen by mucus and tumoral cells, in paracoccidioidomycosis with thickening of the alveolar septa, areas of fibrosis[] (Summary of Microscopic Findings - click here) The alveolar spaces are distended and the alveolar septa are thickened by fibrous tissue.[] […] and alveolar bronchopneumonic exsudate, in sarcoidosis with fibrosis or clustering of granulomas and in idiopathic pulmonary fibrosis with alveolar septa thickening due to[]

  • Chronic Eosinophilic Pneumonia

    The alveolar septa were thickened due to edema and an infiltrate of numerous mononuclear cells and eosinophils, with a few lymphocytes and occasional plasma cells.[]

  • Lipid Pneumonia

    […] with thickening of the alveolar septa and occupation of the lumen by mucus and tumoral cells, in paracoccidioidomycosis with thickening of the alveolar septa, areas of fibrosis[] […] infiltrate Moves to thicken interstitial septa , then Into macrophages enlarging lymphatics Finally produces a fibrosing reaction Imaging Usually lower lobes with predilection[] Thickening of the interlobular septa or fibrosis in the adjacent lung tissue, due to lipid-filled macrophage migration from the alveolar space into the lung interstitium,[]

  • Pneumocystis Carinii Pneumonia

    Histologic findings of lung-tissue samples showed granulomatous tissue (patient 1) and organizing pneumonia with thickening of alveolar septa (patient 2), and immunohistochemical[] A lung biopsy would show thickened alveolar septa with fluffy eosinophilic exudate in the alveoli.[] […] of the alveolar septa and alveoli , leading to significant hypoxia , which can be fatal if not treated aggressively.[]

  • Pulmonary Interstitial Glycogenosis

    There was diffuse interstitial thickening of the alveolar septa by mesenchymal cells, without prominent hyperplasia of type 2 pneumocytes, and without airspace exudates.[] High‐resolution computed tomography (HRCT) revealed ground‐glass opacification and thickened interstitial septae in both infants.[] Parafn-embedded samples showed diffuseinterstitial thickening, with no apparent hyperplasia ofthe alveolar septa by mesenchymal cells.[]
