Background: About 20% of COVID-19 patients can have digestive symptoms, apart from the typical chest-related symptoms, and 10% of patients may have only gastrointestinal (GI) symptoms during their entire disease course.
Aim and objective: The purpose of this study was to describe the spectrum of abdominal computed tomographic (CT) findings in a cohort of 15 COVID-19 patients (confirmed on reverse transcription polymerase chain reaction (RT-PCR)) who presented with various GI presentations without preceding respiratory symptoms.
Materials and methods: A total of 93 patients with COVID-19 (confirmed on RT-PCR) who underwent CT imaging (between September 28, 2020 and March 20, 2021) in our center were retrospectively searched from the existing database. Among those, 15 patients having index presentation with abdominal symptoms and underwent CT abdomen were further evaluated.
Results: Biliary stasis in the form of distended gallbladder and wall thickening was the most common finding, seen in 66.7% (n = 10) patients, followed by bowel wall thickening. Small bowel and large bowel thickenings were seen in 26.7% (n = 4) and 20% (n = 3) patients, respectively. Other findings include fluid-filled colon (n = 1), mesenteric venous thrombosis (MVT) (n = 2), paper-thin bowel wall and pneumatosis (n = 1), acute pancreatitis (n = 1), and ascites (n = 2). One patient who presented with abdominal pain did not show any obvious imaging findings on CT.
Conclusion: Patients with COVID-19 can present with initial GI symptoms preceding typical respiratory symptoms. CT imaging helps in identifying the GI involvement, to rule out alternate etiologies, and also aids in appropriate management planning.
