There may also be multiple nodules. One or more lung nodules can be an incidental finding found in up to 0.2% of chest X-rays [3] and around 1% of CT scans. [4] The nodule most commonly represents a benign tumor such as a granuloma or hamartoma, but in around 20% of cases it represents a malignant cancer, [4] especially in older adults and ...
The findings on chest imaging in DIPNECH patients are bilateral and diffuse. The most frequent findings on a computed tomography (CT) of the chest are multiple primary nodules and/or masses, on a background of mosaic attenuation and airway wall thickening. [2] [9] The nodules have an indolent pattern of growth and are found throughout the lungs.
On radiological studies, pneumothorax is visualized using conventional chest x-rays and CT scans. In 90% of the cases, the pneumothorax is located on the right side. In some cases, small nodules can be seen in the pleura using CT scans. Confirmation can be done using video assisted thoracoscopic surgery (VATS). [8]
The cannonball sign is a radiological term used to describe the presence of multiple, well-circumscribed, round opacities seen on X-ray or CT imaging, typically in the lungs. [1] This finding is most commonly associated with hematogenous metastases, where malignant cells spread to the lungs via the bloodstream, forming discrete nodules that ...
Chest Imaging: either chest x-ray or CT scan, must show bilateral opacities that cannot be fully explained by other conditions such as effusion, lung/lobar collapse, or lung nodules. Origin of Edema: respiratory failure that cannot be fully explained by cardiac failure or fluid overload, this needs objective assessment such as an echocardiogram.
Contrasted CT scans of the chest are usually used to confirm diagnosis of for lung cancer and abscesses, as well as to assess lymph node status at the hila and the mediastinum. CT pulmonary angiogram , which uses time-matched ("phased") protocols to assess the lung perfusion and the patency of great arteries and veins , particularly to look for ...
The diagnosis of DPB requires analysis of the lungs and bronchiolar tissues, which can require a lung biopsy, or the more preferred high resolution computed tomography (HRCT) scan of the lungs. [7] The diagnostic criteria include severe inflammation in all layers of the respiratory bronchioles and lung tissue lesions that appear as nodules ...
Pulmonary hypertension, heart failure, pneumonia, pulmonary embolism [1] Usual onset: Gradual [1] Causes: Unknown [2] Risk factors: Cigarette smoking, certain viral infections, family history [1] Diagnostic method: CT scan, lung biopsy [3] Differential diagnosis: Sarcoidosis, other interstitial lung diseases, hypersensitivity pneumonitis [4 ...
