The radiographic features of pulmonary Langerhans cell histiocytosis are characterized by a combination of micronodules and cysts that predominantly involve the upper and middle lung zones. All radiographic abnormalities may regress as a result of smoking cessation. Cystic spaces exhibit bizarre irregular configurations with bilobed or cloverleaf morphologies may result from coalescence of adjacent cysts. Uncommon radiographic features include consolidation, pleural effusion, and a solitary nodule.
