417 Possible Causes for Septal Thickening

Bronchoalveolar lavage revealed occult alveolar hemorrhage.[ncbi.nlm.nih.gov] Treatment with imatinib resulted in rapid clinical improvement and decrease of ground-glass opacities and lobular septal thickening on high-resolution computed tomography.[ncbi.nlm.nih.gov]

  • Pulmonary Alveolar Microlithiasis

    High resolution CT scan revealed diffuse ground-glass attenuation with superimposed septal thickening (“crazy-paving” pattern).[doi.org] High-resolution CT (HRCT) revealed diffuse ground-glass opacities throughout both lungs, micronodular densities, interlobular septal thickening, linear calcifications along[ncbi.nlm.nih.gov] High resolution CT scan revealed diffuse ground-glass attenuation with superimposed septal thickening ("crazy-paving" pattern).[ncbi.nlm.nih.gov]

  • Diffuse Pulmonary Lymphangiomatosis

    Diffuse interstitial septal thickening was found on a serial follow-up chest computed tomography scan, and lymphangitic metastasis was the primary radiologic differential[ncbi.nlm.nih.gov] Nineteen patients had interlobular septal thickening, 18 had diffuse ground-glass opacities, 22 had pleural effusion, 14 had extrapleural soft-tissue thickening, 20 had pericardial[ncbi.nlm.nih.gov] CT chest Described features include 4 increased interlobular septal thickening peribronchovascular thickening patchy ground glass opacities pleural thickening pleural effusion[radiopaedia.org]

  • Hypersensitivity

    Video-assisted thoracoscopy with biopsy revealed alveolar septal thickening and an inflammatory infiltrate composed mainly of lymphocytes, suggestive of chronic hypersensitivity[ncbi.nlm.nih.gov]

  • Idiopathic Acute Eosinophilic Pneumonia

    High-resolution chest computed tomography scan revealed patchy ground glass opacity and ill-defined nodules, diffuse interlobar and interlobular septal thickening, and bilateral[ncbi.nlm.nih.gov] CT Described features include 4,6,9 : bilateral ground-glass areas: common interlobular septal thickening : common pleural effusions : can be present in 80% (range 60-100%[radiopaedia.org]

  • Pulmonary Alveolar Proteinosis

    GGOs and interlobular septal thickening were observed bilaterally in all patients.[ncbi.nlm.nih.gov] There are areas of patchy ground-glass opacification with smooth interlobular septal thickening and intralobular interstitial thickening (white circles) a polygonal pattern[learningradiology.com] High-resolution computed tomography (CT) of the chest showed a bilateral ground-glass opacity with interlobular septal thickening, creating a mosaic, or “crazy paving,” pattern[nejm.org]

  • Hypertrophic Cardiomyopathy

    Short-axis cine end-diastolic magnetic resonance angiogram shows asymmetric hypertrophy with septal thickening (S). Cardiomyopathy, hypertrophic.[emedicine.com] thickening, particularly at the confluence of the anterior septum and anterior free wall Symmetric, apical and other atypical distributions of hypertrophy are also described[pathologyoutlines.com] This decreases the septal thickening and reduces the left ventricular outflow obstruction. It acts in the same way as a surgical myomectomy, but is less invasive.[symptoma.com]

  • Carcinomatosis

    thickening Thickening of the fissures from infiltration of lymphatics in the subpleural space Peribronchovascular thickening which predominates over interlobular septal thickening[learningradiology.com] Typically the appearance is that of interlobular septal thickening , most often nodular and irregular, although smooth thickening may also sometimes be seen 1-4 .[radiopaedia.org] […] in a minority of patients Polygonal arcades or polygons with prominence of the centrilobular bronchovascular bundle in association with interlobular septal thickening (50%[learningradiology.com]

  • Pulmonary Capillary Hemangiomatosis

    Radiologically, the presence of centrilobular nodules, interlobular septal thickening, and significant mediastinal adenopathy are useful in identifying this subgroup from[ncbi.nlm.nih.gov] However, there was no prominent interlobular septal thickening, pleural effusion, or mediastinal lymphadenopathy.[circ.ahajournals.org] thickening, mediastinal adenopathy on chest CT, hemosiderin-laden macrophages on BAL, lower DLCO, and more severe hypoxemia) Pulmonary Hypertension/Cor Pulmonale (see Pulmonary[mdnxs.com]
