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.
