The NAAT result obtained by RT-PCR detection of SARS-CoV-2 from blood specimens of the patient … Image 4 is a CT image through the apex of the lung showing thickened secondary lobules in a patient with mild emphysema, and 5 shows marked thickening of the interlobular septa in a patient with end stage sarcoidosis. The most common abnormalities on HRCT were ground-glass opacities (n = 17), consolidation (n = 14), interlobular septal thickening (n = 15) and centrilobular nodules (n = 8). They are composed of connective tissue and contain lymphatics and pulmonary venules. Lymphatics are not usually seen but in this instance since they are obstructed, they have become distended with milky white lymph and measure about .05mms . Often the large node may be reactive and may not contain malignant disease. Gegenüber dem Begriff knotig ist der Begriff irreguläre Septumverdickung zu bevorzugen. The first image in the upper left shows marked thickening of the interlobular septa caused by granulomatous changes along the lymphatics. These lobules are well formed at the lung apices, lung bases and particularly at the periphery of the lung. interlobular septum in English translation and definition "interlobular septum", Dictionary English-English online. Re-evaluation of the transbronchial lung biopsy specimen revealed fibrous thickening of the interlobular septum and oedematous thickening of the alveolar wall, with congestive capillary proliferation (capillary haemangiomatosis) , compatible with PV occlusion.

Thickening of the interlobular septa is commonly seen in patients with interstitial lung diseases (15,16), but may also be seen in normal elderly patients (17) and otherwise normal smokers. These are the well known Kerley lines, often spoken about but rarely seen. Surprisingly little volume loss has occurred. Lung. 1). They become larger towards the hila, reaching diameters of between 5 to 10mm. CT angiography confirms characteristic findings of a hypoplastic lung with ipsilateral mediastinal shift, interlobular septal thickening likely because of the dilation of pulmonary lymphatics and bronchial veins, a diminutive ipsilateral PA, and absence of ipsilateral pulmonary vein drainage into the left atrium. Certain diseases have a predilection for the lymphatic system at the subpleural level including sarcoidosis. It may be due to fluid, cellular infiltration, or fibrosis.

The A-P and lateral view of the chest is from a patient with sarcoidosis showing classical egg shell calcification of the mediastinal nodes and hilar nodes. Lymphoid aggregates are uncommon in the lung under normal circumstances. The lobule, defined as the smallest unit of lung structure marginated by connective tissue septa (interlobular septa), is supplied by a centrally located bronchiole and pulmonary artery branch. Note also how thin the alveolar septa are: they contain a single capillary. Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), is a group of lung diseases affecting the interstitium (the tissue and space around the alveoli (air sacs of the lungs).
