Abstract:
A congenital diverticulum of the ileum (Meckel's diverticulum), approximately 10 mm long, was detected in a rat and examined histologically. The histological findings were basically the same as in the ileum. Although Meckel's diverticulum is uncommon in the rat, the present report demonstrated the possibility of discovering new cases.
Insights
A rare Meckel's diverticulum was found in a rat and studied. Histology showed it resembles the ileum, suggesting new cases can be identified.
Area of Science:
- Veterinary Pathology
- Gastrointestinal Anatomy
Background:
- Meckel's diverticulum is a congenital anomaly of the small intestine.
- Its occurrence in rats is considered uncommon.
Purpose of the Study:
- To report the histological findings of a Meckel's diverticulum in a rat.
- To highlight the potential for identifying such anomalies in rat models.
Main Methods:
- A congenital diverticulum of the ileum was identified in a rat.
- Histological examination of the diverticulum was performed.
Main Results:
- The diverticulum measured approximately 10 mm in length.
- Histological features were comparable to those of the normal ileum.
Conclusions:
- Meckel's diverticulum, though uncommon, can be found in rats.
- This case demonstrates the possibility of discovering and characterizing new instances of this anomaly in rats.
