Ulcerating Ileocolitis in Severe Amatoxin Poisoning

Area of Science:

• Toxicology
• Gastroenterology
• Internal Medicine

Background:

• Amatoxin poisoning, often from mushroom ingestion, carries significant mortality and potential complications.
• While acute gastroenteritis is common, late-onset gastrointestinal issues are rarely documented.

Purpose of the Study:

• To report a rare case of delayed gastrointestinal complication following severe amatoxin poisoning.
• To emphasize the importance of considering unusual presentations in Amanita intoxication.

Main Methods:

• Case report of a 57-year-old female with severe amatoxin poisoning.
• Clinical presentation, diagnostic imaging (CT scan), and endoscopic biopsies were utilized.
• Exclusion of infectious and other etiologies was performed.

Main Results:

• The patient developed severe abdominal pain and watery diarrhea on day 8 post-ingestion.
• Computed tomography revealed bowel wall thickening consistent with ileocolitis.
• Biopsies confirmed distinct ileitis and colitis, with no alternative causes identified.

Conclusions:

• This case suggests a likely causal link between amatoxin poisoning and the development of ulcerating ileocolitis.
• Delayed gastrointestinal complications should be considered in patients with a history of mushroom poisoning.
• Prompt diagnosis and management are essential for favorable outcomes in severe amatoxin poisoning.
