Abstract

Traumatic pulmonary pseudocyst (TPP) is a rare entity that occurs following a trauma to the chest. It usually presents as multiple cystic lesions on thoracic imaging. It is treated conservatively and tends to completely resolve after few months. In the absence of striking signs of trauma such as rib fractures, TPP can be mistaken for other cystic lung diseases. We present a case of TPP in a 17-year-old male who was seen for mild hemoptysis after falling off a cliff. The extent of his right lower lobe cystic lesions along with the lack of major signs of trauma led to an incorrect diagnosis of congenital pulmonary airway malformation. The patient was considered for lobectomy, which he refused. Imaging of the chest repeated one and three years later showed complete resolution of the lesions.

Highlights

Traumatic pulmonary pseudocysts (TPPs) are cystic and cavitary lesions that can develop in the lung parenchyma after a trauma to the chest [1]
[2] We present a case where TPP was initially misdiagnosed as congenital pulmonary airway malformation (CPAM) and highlight the potential consequence of such misdiagnosis
Cystic lesions typically affect the lower lobes of the lungs in CPAM and TPP and can be single or multiple and unilateral or, rarely, bilateral

Summary

Introduction

Traumatic pulmonary pseudocysts (TPPs) are cystic and cavitary lesions that can develop in the lung parenchyma after a trauma to the chest [1]. TPP remains a rare entity, awareness of this benign condition is imperative as it may mimic other more serious pulmonary cystic diseases. [2] We present a case where TPP was initially misdiagnosed as congenital pulmonary airway malformation (CPAM) and highlight the potential consequence of such misdiagnosis TPP remains a rare entity, awareness of this benign condition is imperative as it may mimic other more serious pulmonary cystic diseases.
