(26) classified pleural tags into three different categories, with type 1 as one or more linear pleural tags, type 2 as one or more linear pleural tags with soft-tissue component at pleural end, and type 3 as one or more soft-tissue cord-like pleural tags on the mediastinal window. The authors proposed that the presence of type 2 pleural tags in lung cancer that does not abut the pleura may predict visceral invasion with an accuracy of 71%, sensitivity of 36.4%, and specificity of 92.8% (26).
Also HRCT images were evaluated in the mediastinal window for the presence of thymic hyperplasia (TH) (increased thymic thickness with [greater than or equal to]13 mm), MLNE (MLNE) (increased short-axis diameter with [greater than or equal to]10 mm), pleural or pericardial abnormalities (effusion or thickening).

[sup.18]F-fluorodeoxyglucose PET/CT (GE Discovery 690, GE Healthcare, Milwaukee, USA) imaging displayed a poor-defined 55.9x29.5 mm irregular lesion with round low-density inside in the right S3 segment (Figure 1a) at mediastinal window setting.
Lung and mediastinal window images showed conglomerate sausage shaped bilateral masses with calcification, surrounding reticulations, and fibrosis predominantly involving the upper lobes of lungs.
Caption: Figure 2: Chest CT (mediastinal window) scan showed bilateral pulmonary nodules and a solid, enhancing mass with cavitation of 6.5 cm at its largest diameter.
Multidetector computed tomography (MDCT) of chest (mediastinal window, figures 3a and 3b) revealed diffuse ground-glass opacities in bilateral lung parenchyma, septal thickening, and calcification along the interlobar septa and subpleural regions with black pleural lines.
2a and b) of the chest in lung and mediastinal window settings are shown below.
Reconstruction of the CT images using the mediastinal window settings revealed scattered air bubbles in the MCA region, based on which the patient was definitively diagnosed as having developed CAAE (Figure 2).
Caption: Figure 3: Contrast-enhanced multislice CT of the chest (a) on mediastinal window showed no thoracic lymphadenopathy.
