Figure 5 Colonoscopy in December 2021: Appendiceal orifice
Subsequently, the patient experienced recurrent intermittent right lower
abdominal pain, with no fever or alterations in bowel habits. In May
2023, a repeat colonoscopy indicated mucosal congestion and erosion at
the appendiceal orifice (Figure 6 ). Histopathological
examination revealed acute and chronic mucosal inflammation, superficial
epithelial changes with erosions, and shallow ulceration, along with
evidence of cryptitis and an increased number of lamina propria plasma
cells. The mucosal surfaces in other parts of the colon remained
unremarkable. Mesalazine was reintroduced, resulting in the resolution
of abdominal pain symptoms, and the patient continues to be regularly
monitored on mesalazine therapy.
