Chest CT has a potential role in the diagnosis, detection of complications, and prognostication of coronavirus disease 2019 (COVID-19). In primary pulmonary tuberculosis, the initial focus of infection can be located anywhere within the lung and has non-specific appearances ranging from too small to be detectable, to patchy areas of consolidation or even lobar consolidation. WebA CT scan also shows the airway (trachea and bronchi) in great detail and can help determine if pneumonia may be related to a problem within the airway. All authors read and approved the final manuscript. An adequate understanding of these differential features can contribute to the early diagnosis of L-PLADC and the subsequent therapeutic strategy. cancer.org/cancer/lung-cancer/about/key-statistics.html, lung.org/lung-health-diseases/lung-disease-lookup/lung-cancer/learn-about-lung-cancer/lung-cancer-research, cancer.org/healthy/stay-away-from-tobacco.html, cancer.org/cancer/lung-cancer/about/what-is.html. It ranks as the leading cause of cancer-related deaths.

Symptoms of lung cancer and pneumonia can look the same: Coughing (sometimes with blood) Wheezing; Chest pain; Shortness of breath; Tiredness or fatigue https://doi.org/10.1186/s13244-022-01200-z, DOI: https://doi.org/10.1186/s13244-022-01200-z. In clinical practice, a number of delayed diagnoses of localized pneumonic-type lung adenocarcinoma (L-PLADC) mimicking pneumonia have been identified due to the lack of knowledge regarding the radiological findings associated with this condition. Insights Imaging 13, 49 (2022). When LADC manifests as parenchymal consolidation, it is often difficult to distinguish from pneumonia, leading to delayed diagnosis. There are two main types of lung cancer: non-small cell and small-cell. The tumor diameter enlarged over time; attenuation increased; air bronchogram, air-space, and GGO component gradually disappeared; and the lesions ultimately became solid masses (Figs. WebA CT scan takes multiple X-rays of the chest, and a computer creates detailed images of the lungs and surrounding structures. For the model with clinical and CT characteristics that differed significantly between the groups, age58years (odds ratio [OR] 1.109; p<0.001); female sex (OR 5.079; p=0.004); GGO component (OR 35.086; p<0.001); irregular air bronchogram (OR 18.746; p<0.001); pleural retraction (OR 4.561; p=0.009); the absence of necrosis (OR 0.007; p<0.001); and the absence of pleural attachment (OR 0.157; p=0.008) were the independent predictors of L-PLADC via multivariate logistic regression analysis. An estimated 235,760 people in the United States will be diagnosed with lung cancer this year. Frontiers in Pediatrics. A chest CT scan can help figure out the cause of lung symptoms such as shortness of breath or chest pain. A history of smoking increases lung cancer risk.

A cancer may look like a round mass, but sometimes it can also either look like a pneumonia or cause a blockage of the air tubes or bronchi which leads to a lung collapse or pneumonia. A and B The two patients were misdiagnosed as pulmonary inflammatory lesion on initial CT. Sequential CT images of the lung window indicate enlarged focal consolidation, increased attenuation, gradual disappearance of air bronchogram and GGO component; eventually, the focal consolidation became a solid mass during follow-up. 136 Zhongshan Road Two, Yuzhong District, Chongqing, 400014, China, Department of Radiology, The Fifth Peoples Hospital of Chongqing, No. Join over 700,000 people who receive the latest news about lung health, including COVID-19, research, air quality, inspiring stories and resources. L-PLADC was identified using the following diagnostic criteria via CT: (1) pneumonia-like consolidation, characterized by an increased intensity of lung parenchyma with the obscuration of the underlying vessels and with a shape that could not be classified as round, oval, or lobulated (e.g., triangular, rectangular, or trapezoidal); (2) isolated and localized lesion, the largest slice of which involved less than half the area of a lobe on axial images.

The American Lung Association advises screening for lung cancer based on recommendations from the U.S. Preventive Services Task Force (USPSTF), a volunteer, independent panel of experts in evidence-based medicine and disease prevention. As expected, we found that patients with L-PLADC were predominantly women and nonsmokers. The model incorporating clinical and CT features can differentiate L-PLADC from L-PIL with a relatively high accuracy. These features mimic infection and may result in an erroneous diagnosis.

This coincides with the morphological evolution of L-PLADC exhibited herein, which indicated that air bronchogram gradually disappears with tumor growth. Hence, we think that L-PLADC may be an early manifestation of LADC and focal consolidation with irregular air bronchogram, GGO component, and pleural retraction should raise suspicion of cancer.
