Mixed connective tissue disease CT
Introduction
Overview
Overview
In MCTD, the tomographic images may show abnormalities related to interstitial lung disease and the presence of esophageal dilatation. Chest CT scan findings include ground glass opacities, irregularities between the peripheral pleura and parenchyma, septal and non-septal lines, intralobular reticular opacities, bronchiolectasis or traction bronchiectasis, areas of cystic spaces (honeycombing pattern), 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 abnormalities related to:[2][3]
- interstitial lung disease
- Ground glass opacities
- Irregularities between the peripheral pleura and parenchyma or small lines perpendicular to the pleura (Interface sign)
- Septal and non-septal lines (linear opacities)
- Intralobular reticular opacities
- Bronchiolectasis or traction bronchiectasis
- Cystic spaces (diameter <1 cm) with thickened walls (honeycombing pattern)
- Areas of decreased attenuation and air trapping on expiratory computed tomography
- esophageal dilatation
- esophagus may be fluid filled or has an air-fluid level
- interstitial lung disease
