Inflamed Mesenteric Pseudocyst Associated with Meckel’s Diverticulitis: Cause or Consequence

Abstract

Introduction: Mesenteric pseudocyst describes an abdominal mass that appears on small bowel mesentery or mesocolon, or at any part of the abdomen and retroperitoneum. This paper aims to emphasize the non-specific clinical appearance and highlight Meckel’s diverticulitis as a potential cause of the development of pseudocyst. Case Report: A 26-year-old male with a palpable mass in the right upper abdominal quadrant and an increased body temperature of 38.3∘C was admitted for further medical investigation. Computed tomography (CT) presented a cystic mass with a diameter of 5.5 cm, and emergency laparotomy was performed. Wedge resection of pathologic findings of small bowel, its mesenterium, and the cyst mass associated with nearby Meckel’s diverticulum was performed. Discussion: Meckel’s diverticulum can be considered as a risk for developing mesenteric pseudocyst, because of its frequent exacerbation of chronic inflammation. This report adds to the limited literature on the association between Meckel’s diverticulum and mesenteric pseudocysts, providing valuable insights that can guide future clinical evaluations and surgical interventions. Early and accurate diagnosis, aided by imaging techniques such as CT and magnetic resonance imaging (MRI), is essential for effective management. This case highlights the potential link between chronic inflammation in Meckel’s diverticulum and the formation of mesenteric pseudocysts. Conclusion: This case highlights the need to consider Meckel’s diverticulitis in patients with mesenteric pseudocysts, suggesting a possible pathophysiological link between them. Surgical resection is recommended for effective management.
