ABSTRACT
Pulmonary artery pseudoaneurysms are a rare but life-threatening cause of hemoptysis. These are saccular dilatations of the pulmonary artery which do not involve all the three layers of the vessel and are prone to rupture. PAPAs are most commonly associated with infections but may also be caused by vasculitis, lung fibrosis, pulmonary hypertension and a multitude of other causes. CT pulmonary angiography is the diagnostic modality of choice allowing delineation of the PAPA, underlying cause and allowing planning of further management. Although treating the underlying cause is an important part of management, endovascular intervention is required in cases with hemoptysis. Long COVID is an entity that is still under evaluation. It has multisystem involvement. We describe the case of a 30-year-old teacher with hemoptysis after COVID who was diagnosed with a PAPA of segmental branch of left upper lobar pulmonary artery and treated with endovascular embolization with coils and glue. His hemoptysis has stopped since then. He also had pulmonary fibrosis and growth of multidrug resistant Klebsiella pneumoniae in sputum. These were treated medically and he has resumed his work as a teacher.
ABSTRACT
Coronavirus disease (COVID-19), caused by a highly contagious novel coronavirus, has seen a rapid surge of cases over the past 6 months spreading to more than 215 countries and posing a global threat to mankind. Reverse transcriptase-polymerase chain reaction (RT-PCR) from pharyngeal swabs is considered the gold standard for diagnosis of this disease. Portable chest radiography (CXR), point of care ultrasound, and computed tomography (CT) are crucial modalities in diagnosis and follow-up. Portable CXR can help in patients who are clinically unstable, and also to prevent the cumbersome process of steriliastion after every CT scan. However, chest CT is useful as a problem-solving tool, to look for progression and complications associated with the disease. In a few cases, in our experience (as has also been documented by others), RT-PCR was negative in early disease, and CT chest was able to detect the radiologi-cal findings raising suspicion of COVID-19. With this pictorial review, we aim to describe and illustrate the typical, and a few atypical, radiological findings of this disease.
