Acute Epiploic Appendagitis in a COVID-19-Positive Patient With Antiphospholipid Syndrome.

As the coronavirus disease 2019 (COVID-19) pandemic is still underway, a range of clinical presentations and pathologies continue to present themselves in unexpected ways. One such pathology is that of epiploic appendagitis, an uncommon and underdiagnosed cause of acute abdominal pain. We present the case of a 50-something-year-old male who presented with left lower quadrant abdominal pain in the setting of acute COVID-19 infection, found to have acute epiploic appendagitis. After persistent moderate to severe abdominal pain, epiploic appendagitis was diagnosed by computed tomography (CT) imaging findings. The patient was managed for his COVID-19 pneumonia over the course of his hospitalization, as well as conservatively managed with pain control measures for his epiploic appendagitis. This is the second reported case in the literature to the best of our knowledge that shares the case of acute epiploic appendagitis in a patient presenting with acute abdominal pain, who is also found to be COVID-19-positive. Procoagulant changes in coagulation pathways are found in patients with severe COVID-19, and contribute to venous thromboembolism in this patient population. Diagnosing and conservatively managing epiploic appendagitis will lead to decreasing misdiagnosis, preventing invasive or inappropriate treatments that may increase harm to patients, and more adequately understanding the complications associated with COVID-19.
