Salient Features of Cystic Lung Diseases Associated With Nodules: Characteristics of Nodules Seen in Cystic Diseases

LIP	Centrilobular, ill-defined ground glass nodules, more profuse in subpleural regions, demonstrating a patchy distribution
LCDD	Nodules are irregular, multiple, and can be bilateral or unilateral
Amyloid	The nodules tend to be localized to lower lobes and subpleural areas. They have sharp, smooth lobulated contours, varying in size from 0.5 to 15 cm, with slow growth and often central cavitation or calcification
PLCH	Irregular mainly in upper and middle lobes, sparing the costophrenic angles

LCDD = light-chain deposition disease; LIP = lymphoid interstitial pneumonia; PLCH = pulmonary Langerhans cell histiocytosis.
