Background
Pulmonary sequestration (PS) associated with massive hemoptysis, hemothorax, and elevated tumor markers or even lung malignancy has been reported in several studies. These clinical features combined with lung lesions on chest imaging are sometimes hard to differentiate from lung malignancies and often complicate the diagnostic procedure.
Case presentation
A 45-year-old man with PS presented with massive hemoptysis, hemothorax, and extremely elevated carcinoembryonic antigen (CEA) in pleural effusion was initially misdiagnosed with advanced lung carcinoma, but was ultimately diagnosed with PS with Aspergillus infection.
Conclusions
PS is rarely concurrent with lung cancer; most of the time, it is misdiagnosed as a malignancy, especially when presenting with a fungal infection, which could remarkably elevate CEA in pleural effusion.
Background: Pulmonary sequestration (PS) associated with massive hemoptysis, hemothorax, and elevated tumor markers or even diagnosed with lung malignancy has been reported many times. But all these clinical features have never been reported in the patient diagnosed with PS without malignant disease.Case presentation: A 45-year-old man with PS presented with massive hemoptysis, hemothorax, extremely elevated carcinoembryonic antigen (CEA) in the pleural effusion, was initially misdiagnosed with advanced lung carcinoma, and was finally diagnosed with PS with Aspergillus infection.Conclusions: PS is rarely concurrent with lung cancer; most of the time, it is easily misdiagnosed as a malignancy, especially when presenting with a fungal infection, which could remarkably elevate CEA in the pleural effusion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
