Traumatic pulmonary pseudocyst a case report: surgery? Follow-up?

Traumatic pulmonary pseudocysts represent uncommon parenchymal sequelae ensuing from thoracic trauma, typically arising subsequent to blunt force trauma. Generally benign in nature, these lesions frequently resolve spontaneously without necessitating specific therapeutic interventions. The significance of these acute cystic formations lies in the potential for misinterpretation by clinicians unfamiliar with their characteristics, leading to erroneous diagnoses such as malignancies or benign lung lesions. In this case report, we wanted to show that traumatic pulmonary pseudocysts, even if large in size, can resolve with follow-up without the need for surgery.
