Peripheral pulmonary infiltrates in sarcoidosis.

The chest roentgenograms are described in eight patients with sarcoidosis who demonstrated a peripheral distribution of pulmonary infiltrates quite similar in appearance to that classically observed in eosinophilic pneumonia. The presence of mediastinal/hilar lymph node enlargement (eight patients), a nodular component to the infiltrate (four patients), an often asymptomatic presentation (four patients), and absence of blood eosinophilia (eight patients) should suggest the correct diagnosis.
