Overview
In MCTD, the tomographic images may show radiographic abnormalities related to interstitial lung disease and the presence of esophageal dilatation. Chest CT scan findings include ground glass opacities, irregularity of the interfaces between the peripheral pleura and aerated lung parenchyma, septal and nonseptal lines, intralobular reticular opacities, bronchiolectasis or traction bronchiectasis, areas of cystic spaces (honeycombing), areas of decreased attenuation and air trapping on expiratory computed tomography.
CT scan
- Computed tomography may be helpful in early diagnosis of interstitial lung disease.[1]
- In MCTD, the tomographic images may show radiographic abnormalities related to interstitial lung disease and the presence of esophageal dilatation:[2][3]
- Areas of increased attenuation in which the bronchi and vessels remain visible (ground glass opacities)
- Irregularity of the interfaces between the peripheral pleura and aerated lung parenchyma or small lines perpendicular to the pleura (Interface sign)
- Septal and nonseptal lines (linear opacities)
- Intralobular reticular opacities
- Bronchiolectasis or traction bronchiectasis: dilatation of the airways in the peripheral portion of the lungs
- Areas of cystic spaces (diameter <1 cm) with thickened walls (honeycombing)
- Areas of decreased attenuation and air trapping on expiratory computed tomography
- Esophageal dilatation (esophagus may be fluid filled or has an air-fluid level)
