Multiple cavitary pulmonary metastases from pancreatic cancer diagnosed using transbronchial lung cryobiopsy

Abstract

Abstract Multiple cavitary pulmonary metastases are rare, and cavitary lung lesions have various aetiologies and differential diagnoses. Therefore, radiological diagnosis of lung cavities is extremely difficult. Herein, we report a case of pancreatic cancer with multiple cavitary pulmonary metastases diagnosed using transbronchial lung cryobiopsy (TBLC), that required differentiation from pulmonary lesions of Sjögren's syndrome whose pulmonary manifestation may present as bronchiectasis and cystic change. TBLC may be useful for the diagnosis of multiple lesions because sufficiently large specimens can be obtained to allow pathological evaluation of the lung parenchyma and bronchiolar lesions.
