Answer

High-resolution computed tomography (HRCT) and scintigraphy reveal thickening of the alveolar walls and intestinal tissue and honeycomb-appearing lungs.

Gastrointestinal tract changes may be depicted. Scintigraphy of the esophagus may reveal a disturbance of the esophageal passage. [34] Manometric esophageal changes may be observed during invasive examination. Upper gastrointestinal tract evaluation should be performed only in systemic sclerosis, but not in morphea. [35]
