title: Intrapulmonary schwannoma diagnosed with endobronchial ultrasound-guided transbronchial needle aspiration: case report.
abstract: A 47-year-old woman was referred to our hospital for further examination of a lung tumor. CT of the chest revealed a round, well-defined 2.4-cm nodule in S2, adjacent to right superior lobe bronchus. Endobronchial ultrasonography showed a well-defined, hypoechoic tumor with echogenic capsule and posterior acoustic enhancement. Diagnosis of schwannoma was confirmed from the specimen obtained by endobronchial ultrasound-guided transbronchial needle aspiration. She underwent tumorectomy due to the possibility of obstructive pneumonia. Pathology diagnosis from the surgical specimen was also schwannoma. Endobronchial ultrasound-guided transbronchial needle aspiration and findings with endobronchial ultrasonography might be helpful in the diagnosis of intrapulmonary schwannoma.
