Scleroderma

HRCT in a 34-year-old woman with scleroderma shows reticulation, traction bronchiectasis, and ground-glass opacity with a posterior, subpleural, and lower lobe predominance. No definite honeycombing is present. The major fissures are displaced posteriorly (red arrows) as a result of fibrosis and volume loss. These findings are consistent with fibrotic NSIP associated with scleroderma. IPF without honeycombing could have a similar appearance. Note that the esophagus is dilated (blue arrow), a finding typical of scleroderma.
