X Ray

Shrinking lung (radiograph):  unexplained dyspnoea. restrictive pattern onpulmonary function tests.

Chest x-ray often shows small but clear lungs with diaphragmatic elevation. Occasional basal atelectasis may be present. 

Pleural fibrosis: Pleural thickening

Pulmonary infarct

• wedge-shaped (less often rounded) juxtapleural opacification (Hampton hump) without air bronchograms
• more often in the lower lobes

Pulmonary hypertension

• elevated cardiac apex due to right ventricular hypertrophy
• enlarged right atrium
• prominent pulmonary outflow tract
• enlarged pulmonary arteries
• pruning of peripheral pulmonary vessels

Plumonary alveolar hemorrhage:

Patchy bilateral and acinar areas of increased opacity, predominantly in the lower lungs

Respiratory muscle dysfunction

elevated hemidiaphragms at chest radiography

linear atelectasis and an ill-defined juxtadiaphragmatic areas of increased opacity 

Wiedemann HP, Matthay RA. Pulmonary manifestations of collagen vascular diseases.Clin Chest Med 1989; 10:677-696

Mesentric vascuitis:

• Plain radiographic studies:
  • Thumb-printing sign: Due to bowel wall edema or intramural hemorrhage
  • Segmental bowel dilatation
  • Air-fluid levels, pneumatosis
  • Narrowing of the lumen
  • Pseudo-obstruction
  • Portal venous gas

Arthritis

• Pericapsular soft-tissue edema
• Synovitis around small joints
• Juxtaarticular osteoporosis

Carpal instability

• Radioulnar deviation: An static deformity
