Pneumothorax (PTX) is a life-threatening condition that overdiagnosis could result in increases in mortality and morbidity of patients, this overdiagnosis would be increased if physicians do not manage the patient classically and do not pay attention to the physical exam and history of the patient.
A-71-year old man was admitted to the emergency department due to multiple trauma. His vital signs were stable and in examination, there were two lacerations on his scalp with venous bleeding source and galea transaction; there were also some abrasions all over his body including his thorax. In the physical exam, there was no sucking lesion, decreases in respiratory sounds in auscultation or chest deformity but he had little right hemithorax rib tenderness. In more evaluations, there was a suspected visceral line of pleura in his CXR and no plural sliding movement was seen in E-FAST by the operator. Due to the inconsistency in physical exam and radiologic findings we decided to take a chest CT-scan before the insertion of the chest tube that indicated no PTX for him and the suspected visceral line in CXR was skin fold of a permacath for hemodialysis.
Several conditions could mimic findings of PTX in CXR that every physician should know and pay attention to them besides special attention to the history taking and physical examination to reduce the mortality and morbidity of patients.
