Pneumatosis intestinalis in COVID-19

Area of Science:

• Gastroenterology
• Infectious Diseases
• Radiology

Background:

• COVID-19, caused by SARS-CoV-2, is primarily a respiratory illness but can affect the gastrointestinal tract.
• Pneumatosis intestinalis (PI) is characterized by the presence of air within the bowel wall.
• The pathogenesis of PI is not fully understood and its association with COVID-19 is rarely reported.

Observation:

• A 44-year-old male patient hospitalized with COVID-19 pneumonia developed incidental pneumatosis intestinalis (PI) involving the cecum and right colon.
• The PI was discovered as a collateral finding on a contrast-enhanced CT scan performed to rule out pulmonary embolism.
• No gastrointestinal symptoms were reported by the patient during hospitalization.

Findings:

• The patient received treatment for COVID-19 and was also treated with antibiotics for the PI.
• A follow-up CT scan after two weeks showed complete resolution of the pneumatosis intestinalis.
• This case represents the first reported instance of PI in the context of COVID-19.

Implications:

• The study hypothesizes a multifactorial etiology for PI in COVID-19 patients, potentially involving SARS-CoV-2-induced bowel wall damage and microbiota alterations.
• It suggests that a conservative management approach may be appropriate for asymptomatic cases of PI in COVID-19 patients.
• Further research is needed to elucidate the exact mechanisms linking SARS-CoV-2 infection to PI and to confirm the efficacy of conservative management.
