Insights

This case report details a rare association of mesenteric schwannoma with intestinal malrotation and an ileal diverticulum in an elderly male. The study highlights diagnostic and therapeutic challenges in managing these uncommon gastrointestinal conditions.

Area of Science:

  • Gastroenterology
  • Surgical Pathology
  • Abdominal Imaging

Background:

  • Mesenteric schwannomas are rare, benign neoplasms originating from nerve sheath cells within the mesentery.
  • Ileal diverticula and intestinal malrotation are infrequently diagnosed in adults, often presenting asymptomatically.
  • The co-occurrence of these conditions presents unique diagnostic and management complexities.

Observation:

  • An 86-year-old male presented with severe abdominal pain and distension.
  • Radiological imaging suggested intestinal malrotation.
  • Exploratory laparotomy revealed intestinal malrotation with intermesenteric bands, a mesenteric mass, and an ileal diverticulum.

Findings:

  • Histological examination of the mesenteric mass confirmed it to be a schwannoma.
  • The patient underwent a segmental enterectomy for treatment.
  • This represents the first reported case of concurrent mesenteric schwannoma, intestinal malrotation, and ileal diverticulum.

Implications:

  • This case underscores the importance of considering rare diagnoses in complex abdominal presentations.
  • Early and accurate diagnosis is crucial for effective surgical planning and patient outcomes.
  • Further research into the etiology and management of such rare associations is warranted.

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Gastrointestinal Motility Disorders01:20

Gastrointestinal Motility Disorders

Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Renewal of Intestinal Stem Cells01:23

Renewal of Intestinal Stem Cells

The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...

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...

Inflammatory Bowel Disease II: Crohn's Disease

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
