A bull horn fragment found on colonoscopy

Area of Science:

• Gastroenterology
• Medical Diagnostics
• Endoscopy

Background:

• An 81-year-old male presented with mild iron deficiency anemia and a positive fecal occult blood test.
• The patient was asymptomatic, highlighting the importance of screening in detecting underlying conditions.

Observation:

• Colonoscopy was performed to investigate the cause of the positive fecal occult blood test.
• A foreign body was identified 40 cm from the anal verge, impeding colonoscope advancement.

Findings:

• The foreign body appeared hard and fixed upon manipulation with biopsy forceps.
• This unusual finding obstructed the colonic lumen, preventing complete examination.

Implications:

• Further investigation is required to identify the nature and origin of the foreign body.
• This case underscores the potential for unexpected findings during endoscopic procedures, even in asymptomatic individuals.
