Small Bowel Volvulus Due to Mesenteric Lymphadenopathy in a COVID-19-Positive Infant: A Case Report

Background: Segmental small bowel volvulus (SBV) is a lesser-known surgical condition that can affect both children and adults. It is characterized by twisting a segment of the small bowel at its mesentery. Delayed diagnosis can lead to detrimental results. Case Presentation: We present a rare case of SBV with normal intestinal rotation in an infant infected with COVID-19, which presented with bloody diarrhea, anuria, poor feeding, and lethargy. Due to dilated intestinal loops in radiological findings and refractory metabolic acidosis, the patient underwent laparotomy surgery which revealed huge mesenteric lymphadenopathy at the site of volvulus, and there was no sign of accompanying malrotation. Devolvulation was performed. After starting breastfeeding a few days later, the patient was discharged home without any complications. To our knowledge, this is the first report that addresses COVID-19-induced lymphadenopathy as a lead point for volvulus in an infant. Conclusion: All clinicians should be aware of SBV as a dangerous and rare disease with a variable presentation to provide the best care for their patients. Mesenteric lymphadenopathy and mesenteric defects can cause segmental volvulus.
