Incidental lung mass: a rare case of intrapulmonary schwannoma mimicking a pulmonary hydatid cyst

Schwannomas are rare, mostly asymptomatic neoplasms originating from peripheral nerves, with primary occurrence in the lung being exceptionally rare. Diagnosis is primarily incidental or prompted by symptoms caused by mass effect on nearby organs. Lacking characteristic clinical or radiological features, their appearance as cystic lung lesions are very likely to be confused with pulmonary hydatidosis, especially in the endemic regions. Thus, whenever an individual presents with an incidental lung mass, schwannoma needs to be considered as one of the differentials alongside other benign cystic lesions or neoplasms.
