Summary
Mineralized cecal trichobezoars, a rare condition in rhesus macaques, were surgically removed from a five-year-old female. Recurrence was observed 13 months later, highlighting the need for further investigation into this gastrointestinal issue.
Area of Science:
- Veterinary Medicine
- Primate Health
- Gastroenterology
Background:
- Trichobezoars are masses of ingested hair or foreign material that can cause gastrointestinal obstruction.
- Cecal trichobezoars are uncommon, particularly in non-human primates.
- Mineralization of trichobezoars presents unique diagnostic and therapeutic challenges.
Observation:
- A five-year-old female rhesus macaque (Macaca mulatta) exhibited poor body condition and palpable abdominal masses.
- Radiographic and surgical findings confirmed the presence of mineralized cecal trichobezoars.
- Recurrence of similar masses was noted 13 months post-surgery.
Findings:
- This case report details the first documented instance of a mineralized cecal trichobezoar in a rhesus macaque.
- Surgical intervention was performed for the removal of the abdominal masses.
- The trichobezoar was found to be mineralized, indicating a complex composition.
Implications:
- This finding expands the understanding of gastrointestinal pathologies in rhesus macaques.
- It underscores the importance of considering mineralized trichobezoars in the differential diagnosis of abdominal masses in non-human primates.
- Further research may be warranted to explore the etiology and long-term management of this condition in this species.
