Article Abstract

We herein present a case involving a 62-year-old woman with a 1-month history of persistent dry cough. A thoracic computed tomography scan revealed multiple cystic lesions with well-defined thin septal thickening, tiny nodules, and areas of irregular consolidation characterized by irregular septal thickening in the right lower lobe. This thickening formed pentagonal and hexagonal patterns resembling a soccer ball. A ground-glass nodule was observed in a different area of the anterior basal segment of the right lung (S8) and was suspected to be adenocarcinoma in situ. This diagnosis was confirmed, along with placental transmogrification of the lung, after the patient underwent right lower lobectomy via video-assisted thoracoscopic surgery. Irregular septal thickening with pentagonal and hexagonal patterns resembling a soccer ball may suggest placental transmogrification of the lung in patients with multiple cystic lesions in a unilateral lung.

Placental transmogrification of the lung (PTL) is a rare cystic lesion characterized by a distinctive microscopic architecture resembling placental villi. Although its etiology remains unclear, PTL is frequently observed with emphysema, suggesting a potential association between these conditions. However, the precise nature of this relationship remains ambiguous, and whether PTL causes or results from emphysema remains unclear.

Congenital lung anomaly (CLA) refers to a rare group of malformations that are typically identified prenatally or in early childhood. However, a significant proportion of cases evade detection until adulthood and either are incidentally discovered or manifest with symptoms of recurrent respiratory infection or pulmonary hemorrhage. While most CLAs have characteristic imaging findings at CT and MRI, they remain a diagnostic challenge due to the infrequency with which they are encountered in adults.
