Cardiac tamponade as the first presentation of thymoma: A case report during COVID-19 pandemic

ABSTRACT

We report a case of neoplastic cardiac tamponade, a life-threatening condition, as the initial presentation of an anterior mediastinal malignancy. A 69-year-old gentleman with no known history of malignancy presented to the emergency department with shortness of breath, reduced effort tolerance and chronic cough. Clinically, he was not in distress but tachycardic. He was subjected to echocardiography which revealed large pericardial effusion with tamponade effect. Pericardiocentesis drained 1.5 L of haemoserous fluid. CECT thorax, abdomen and pelvis revealed an anterior mediastinal mass with intrathoracic extension complicated with mass effect onto the right atrium and mediastinal vessels. Ultrasound-guided biopsy histopathology examination revealed thymoma. Due to locally advanced disease, tumour resection was not possible, and patient was referred to oncology team for chemoradiotherapy. We report this case study not only due to the rarity of the case but also to highlight its diagnostic challenge due to the COVID-19 pandemic. Copyright © The Author(s) 2022.
