2. NSIP
Nonspecific interstitial pneumonitis (NSIP) is temporally and spatially homogeneous, while UIP is typically heterogeneous, patchy, and irregular in size (1). Usual interstitial pneumonia (UIP) is the histopathologic and radiologic pattern of interstitial lung disease, which is the hallmark pattern for idiopathic pulmonary fibrosis (IPF). On imaging, usual interstitial pneumonia usually presents with a lung volume loss and a craniocaudal gradient of peripheral septal thickening, bronchiectasis, and honeycombing. The extent of honeycombing and traction bronchiectasis is greater in UIP than the extent of ground glass opacity or micronodules, which are more commonly associated with an NSIP pattern (1,2).
