Case Presentation: A 23-year old male presented with right lower quadrant abdominal pain. Further evaluation revealed a diagnosis of acute appendicitis. The patient developed a febrile episode on second post-operative day of laparoscopic appendectomy. ECG revealed features consistent with BS. Prompt control of temperature in the patient resolved the ST-segment elevation and prevented potentially life-threatening arrhythmias. Conclusion: Febrile episodes in susceptible patients may unmask a concealed BS. Prompt control of temperature is advocated to reduce the risk of life-threatening arrythmias Arrythmias, Brugada Syndrome, fever, Electrocardiogram, appendectomy. 43 45 http://caspjim.com/browse.php?a_code=A-10-81-2&slc_lang=en&sid=1 Jharendra Rijal jrijal.1@gmail.com 10031947532846002620 10031947532846002620 Yes Staten Island University Hospital Smith Giri smithgiri963@gmail.com 10031947532846002621 10031947532846002621 No University of Tennesse Health Science Center Sumesh Khanal sumesh.khanal@gmail.com 10031947532846002622 10031947532846002622 No Institute of Medicine, Tribhuvan University Teaching Hospital Khagendra Dahal kdahal@gmail.com 10031947532846002623 10031947532846002623 No Lakes Region General Hospital
