Radiology Case Reports
|January 2, 2023
Summary
Appendiceal schwannoma, a rare nerve sheath tumor, can obstruct the appendix, leading to acute appendicitis. This case highlights the importance of considering appendiceal tumors in patients presenting with appendicitis symptoms.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Oncology
Background:
- Schwannomas are typically nerve sheath tumors, rarely found in the gastrointestinal tract.
- Gastrointestinal schwannomas predominantly occur in the stomach and small intestine.
Observation:
- A case of an 83-year-old woman presenting with acute appendicitis symptoms.
- Computed tomography revealed a 1.3 cm mass at the appendix orifice, causing obstruction and distal appendiceal changes.
Findings:
- Histopathological examination confirmed the mass as a schwannoma.
- The appendiceal schwannoma was associated with acute suppurative appendicitis.
Implications:
- This case adds to the limited literature on appendiceal schwannomas.
- Recognizing appendiceal tumors is crucial for diagnosing acute appendicitis, especially in atypical presentations.

01:22Appendicitis-I: Introduction
373
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...

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

166
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

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...
