Abstract

A sarcoidosis is a multisystemic granulomatous disorder that has a predilection for pulmonary involvement, and the common radiological findings for the disease are bilateral nodular or reticulonodular patterns. Pseudoalveolar sarcoidosis is a rare presentation of sarcoidosis. The radiological finding is an alveolar pattern that involves or compresses the alveoli by clustered interstitial granuloma. A 58-year-old man was admitted due to incidental findings of a unilateral consolidative lesion as seen on chest radiography. A chest computed tomography (CT) examination showed multiple bronchoalveolar consolidations that were suspicious of a malignancy. However, a percutaneous needle biopsy revealed non-caseating granuloma with an asteroid body that was compatible with sarcoidosis. After one month, the consolidative lesions improved without any treatment.

Figure 2
(A, B) Initial chest HRCT scans shows a mass-like opacity in the superior and posterobasal segment of the right lower lobe. (C, D) Follow-up chest HRCT (4 months later) scans shows a resolution of previous lesions in the superior and posterobasal segment of the right lower lobe.

The pathologic findings of transthoracic needle biopsy reveals (A) chronic non-caseatng granulomatous inflammation and giant cell (H&E stain, ×200). (B) In high power field, there is a asteroid body (white arrow) in giant cell (H&E stain, ×400).
