Abstract

BACKGROUND:

Sarcoidosis is a multisystemic disorder of unknown cause that primarily affects the lungs. The diagnosis is based on the clinical manifestations, radiological findings and histological examination.

OBJECTIVES:

To review and illustrate the typical and atypical radiological findings of sarcoidosis in the chest.

METHODS:

We analyzed the radiographic thoracic findings of all patients who had biopsy-proven sarcoidosis over the last 10 years.

RESULTS:

There were 100 consecutive patients (36 men and 64 women, age 20-84 years) with an established diagnosis of sarcoidosis. Thoracic lymphadenopathy was detected in 89 patients (89%). Lung parenchyma involvement was found in 60 patients. These changes were variable and included: ground-glass attenuation (n=39), multiple small nodules (n=44) and irregular thickening of the interlobular septa (n=16). Larger nodules (1-3 cm) were identified in 12 patients and frank consolidations were seen in 12 patients. Pleural thickening with subpleural nodules was identified in 17 patients.

CONCLUSIONS:

Sarcoidosis has a wide variety of radiological manifestations in the chest. Familiarity with the various radiographic findings is important for diagnosis and management.
