Background: Boerhaave's syndrome (BS) is a rare life-threating condition with poor prognosis. Unfortunately, due to its very low incidence, no clear evidences or definitive guidelines are currently available: in detail, surgical strategy is still a matter of debate. Most of the case series reports thoracic approach as the most widely used; conversely, transhiatal abdominal management is just described in sporadic case reports. Read More

Coronavirus disease 2019 (COVID-19) is a pandemic infection due to the spread of a novel coronavirus (severe acute respiratory syndrome coronavirus 2), resulting in a wide range of clinical features, from asymptomatic carriers to ARDS. The gold standard for diagnosis is nucleic acid detection by real-time reverse transcriptase-polymerase chain reaction in nasopharyngeal swabs. However, due to limitations in this technique's sensitivity, thoracic imaging plays a crucial, complementary role in diagnostic evaluation and also allows for detection of atypical findings and potential alternative targets for sampling (eg, pleural effusion).
