Abstract

Pulmonary sclerosing pneumocytoma (PSP) is a rare condition, occupying only approximately 1% of all benign lung neoplasms and the description of this disease through a radiological perspective is limited. Only approximately a third of PSP has been correctly diagnosed pre-operatively through contrast-enhanced computed tomography (CECT) thorax. To date, only few radiological features have been described to ascertain this disease and there is still a significant portion of patients being misdiagnosed with a malignant neoplasm. We report a case of PSP that was initially misdiagnosed as lung adenocarcinoma stage IIA and the histopathological findings of surgical resection confirmed the diagnosis of PSP. We try to add some points from this case into the previous radiological description of this uncommon disease with a common presentation.
