title: Necrotizing granuloma of the lung: imaging characteristics and imaging-guided diagnosis.
abstract: OBJECTIVE
  The purpose of this study was to assess CT findings and the sensitivities of imaging-guided fine-needle aspiration (FNA) biopsy and core needle biopsy in the diagnosis of necrotizing granuloma of the lung.
  
  
  CONCLUSIONS
  The CT characteristics of necrotizing granuloma are indistinguishable from those of malignant tumors; tissue diagnosis therefore is necessary. Core needle biopsy is a sensitive method for diagnosing necrotizing granuloma of the lung, but FNA biopsy is insufficient for diagnosis.
