[Minute Pulmonary Meningothelial-like Nodule:A Case Report and Literature Review]

Minute pulmonary meningothelial-like nodule(MPMN)is a rare respiratory disease with no specific clinical manifestations and requires bronchial or percutaneous lung biopsy for diagnosis.Here we report a case of an old male patient with recurrent cough and sputum as the main manifestations,which failed to be cured by antibiotic.His chest computed tomography showed a mass-like tumorous lesion located in the posterior segment of the right upper lobe,and the pathological diagnosis by percutaneous lung biopsy confirmed MPMN with lung infection.At the same time,we reviewed 34 cases to summarize the clinical data,pathological manifestation,diagnosis,treatment,and prognosis of MPMN.
