The radiological presentation of Rasmussen aneurysm secondary to pulmonary tuberculosis and COVID-19: A case report

Rasmussen aneurysm is rare diagnosis occurring in patients with long-standing tuberculosis. TB-COVID-19 co-infection in the context of Rasmussen aneurysm is a rare occurrence, yet new cases are emerging. An elderly male was recently diagnosed with TB-COVID-19 co-infection and presented with sudden onset massive hemoptysis. The patient was diagnosed with Rasmussen aneurysm after being evaluated by computed tomography pulmonary angiogram due to a suggestive clinical presentation. Interventional radiologists planned for embolization of pulmonary artery, with an unidentifiable source. It was suspected that the patient's source of bleeding was hampered due to local tamponade effect or thrombosis of the aneurysm. The patient remained stable after 24 hours on computed tomography pulmonary angiogram. Our case emphasizes the importance of Rasmussen aneurysm as a differential diagnosis when presented with a TB-COVID-19 co-infection and sudden onset of hemoptysis symptomatically and radiologically. The timely diagnosis and management are key to improve mortality.
