ACE and vasculitis: Substantial overlap is seen between nodular sarcoidosis and NSG pattern in terms of clinical symptoms and extrapulmonary manifestations.[1] Patients with NSG pattern are reported to be less likely to have hilar or mediastinal lymphadenopathy with increased serum angiotensin-converting enzyme than those with nodular sarcoidosis.[1,3,4] Vasculitis such as GPA or eosinophilic GPA can also present multiple lung nodules with solid or ground-glass opacity that often show air bronchogram or necrosis with cavitation.
