Interlobular Septal Thickening. She had no history of smoking, allergy or respiratory disorders. Crazy paving in ILD is a CT feature of interstitial lung disease and is characterised by diffuse ground glass caused by a combination of interlobular septal and intralobular septal thickening resulting well demarcated patchy densities in the lungs. (F) Chest CT scan of a 70-year-old male patient after 3 days of treatment. Interlobular septal thickening, centrilobular nodular nodules, and ground glass opacities are frequently observed on chest computed tomography (CT). An open-lung biopsy is the best method of diagnosing this condition, as less invasive techniques do not provide an adequate tissue specimen. In case 1, the post‐treatment chest CT revealed that GGO in bilateral lungs were increased, furthermore intra‐ and interlobular septal thickening region, bronchiectasis within GGO were emerged. Pathol. It is often seen as fine linear or reticular thickening. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers.

Treatment and Prognosis Oral trimethoprim-sulfamethoxazole (TMP-SMX) is first-line treatment of patients with PJP. thickening in the lesion, 16 (47.1%) with air broncho-gram sign, 29 (85.3%) with interlobular septal thickening, 22 (65.2%) with “feather signs”, 18 (52.9%) with “dande-lion sign” and 21 (61.8%) with pulmonary fibrous tissue proliferation. Thickening of the interlobular septa is a common and easily recognizable finding at high-resolution computed tomography (HRCT; 1-2 mm collimation high-spatial-frequency reconstruction algorithm). A computed tomography chest scan with contrast demonstrated new bilateral pleural effusions and symmetric alveolar infiltrates with interlobular septal thickening, consistent with taxane-induced pneumonitis (Fig 1A). There are many causes of interlobular septal thickening, and this should be distinguished from intralobular septal thickening. However, in most patients, interstitial thickening is not extensive. This report features an ex-coal miner, thought to … On HRCT, numerous clearly visible septal lines usually indicates the presence of some interstitial abnormality. Insights Imaging. 2.

Interlobular septal thickening is commonly seen in patients with interstitial lung disease. Some of them have a rounded shape and interlobular septal thickening; note new ground-glass opacities in Figure 1B. Another form of iatrogenic pulmonary oedema occurs as a consequence of rapid re-expansion of atelectatic lung, following drainage or evacuation of moderate-to … The septa are usually perpendicular to the pleura in the lung periphery. Chest high-resolution computed tomography revealed patchy ground-glass opacities and interlobular septal thickening without pleural effusion. Thickening of the interlobular septa can be smooth, nodular or irregular, with many entities able to cause more than one pattern. It may be due … The septal thickening pathologically corresponds to inflammatory infiltration or fibrosis (5,10). Criado E, Sánchez M, Ramírez J, Arguis P, de Caralt TM, Perea RJ, Xaubet A.
