[11] [18] This is sometimes accompanied by the development of a crazy paving pattern and interlobular septal thickening. [18] In many cases the most severe pulmonary CT abnormalities occurred within 2 weeks after symptoms began. [17] At this point, many individuals begin showing resolution of consolidation and GGOs as symptoms improve.
The gross appearance of a lipid pneumonia is that in which there is an ill-defined, pale yellow area on the lung. This yellow appearance explains the colloquial term "golden" pneumonia. [7] At the microscopic scale foamy macrophages and giant cells are seen in the airways, and the inflammatory response is visible in the parenchyma. [citation ...
On radiological studies, diffuse lesions are visualized throughout the thoracic cavity using CT scans. The location of the lesions is mostly in the upper lobes of the lungs, usually in a lymphatic distribution. Thickening of the pleura and interlobular septal is also evident.
It is an area that is insensitive to pain due to its association with the lung and innervation by visceral sensory neurons. [8] Visceral pleura also forms interlobular septa (that separates secondary pulmonary lobules). [9] Interlobular septa contains connective tissue, pulmonary veins, and lymphatics. [10]
They may be seen in any zone but are most frequently observed at the lung bases at the costophrenic angles on the PA radiograph, and in the substernal region on lateral radiographs. [3] Causes of Kerley B lines include pulmonary edema, lymphangitis carcinomatosa and malignant lymphoma, viral and mycoplasmal pneumonia, interstitial pulmonary ...
Pulmonary interstitial emphysema (PIE) is a collection of air inside the lungs but outside the normal air space of the alveoli, found as pneumatoses inside the connective tissue of the peribronchovascular sheaths, interlobular septa, and visceral pleura.
Indium lung is a rare occupational lung disease caused by exposure to respirable indium in the form of ... interlobular septal thickening, honeycombing, and ...
Crazy paving refers to a pattern seen on computed tomography of the chest, involving lobular septal thickening with variable alveolar filling. The finding is seen in pulmonary alveolar proteinosis, [1] and other diseases. [2] Its name comes from its resemblance to irregular paving stones, called crazy pavings. [3]
