Summary
This case report details a rare paracaecal amoeboma causing abdominal pain and rectal bleeding. The amoeboma involved fistulae to the appendix and bladder, successfully treated with surgery and medication.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Surgical Pathology
Background:
- Amoebiasis is a parasitic infection typically affecting the colon.
- Intestinal amoebiasis can present with diverse clinical manifestations, including inflammatory masses.
Observation:
- A 63-year-old woman presented with abdominal pain, a palpable right iliac fossa mass, and rectal ulceration.
- Laparotomy revealed an inflammatory paracaecal mass with fistulae involving the appendix, small bowel, and urinary bladder.
Findings:
- Microscopic examination confirmed invasive amoebae within the resected mass.
- Surgical excision followed by metronidazole and diloxanide treatment resulted in successful re-anastomosis.
Implications:
- This is the first reported case of a paracaecal amoeboma presenting with fistulae to both the appendix and urinary bladder.
- Highlights the importance of considering amoebiasis in the differential diagnosis of complex abdominal masses, even with unusual fistulating patterns.
