Insights

Infected mesenteric cysts are rare but can cause acute abdominal pain. This case highlights the importance of surgical removal for mesenteric cysts, even when asymptomatic, to prevent severe complications like infection.

Area of Science:

  • Gastroenterology
  • Surgical Pathology

Background:

  • Mesenteric cysts are uncommon intra-abdominal tumors, often asymptomatic and incidentally discovered.
  • Complications like infection, bleeding, torsion, rupture, or obstruction can lead to acute abdominal conditions.

Observation:

  • A 26-year-old woman presented with acute abdominal pain and a palpable right abdominal mass.
  • Computed tomography revealed a cystic mass in the mesenteric region of the ascending colon.
  • Laparotomy identified two mesenteric cysts in the ascending colon, filled with turbid fluid and infected with E. coli.

Findings:

  • The mesenteric cysts were diagnosed as pseudocysts due to E. coli infection.
  • Histological examination showed fibrotic walls without epithelial lining.
  • The patient underwent a right hemicolectomy for treatment.

Implications:

  • Mesenteric cysts, despite being rare, can lead to life-threatening complications such as spontaneous infection.
  • Complete surgical excision of mesenteric cysts is recommended, regardless of initial presentation or incidental diagnosis, to mitigate risks.

Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Appendicitis01:19

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...
Cholecystitis01:20

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
Giardiasis01:12

Giardiasis

Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
