Intussusception of the Appendix that Reduced Spontaneously during Follow-up in a Patient on Hemodialysis Therapy
A 63-year-old man on long-term hemodialysis therapy was hospitalized due to right lower abdominal pain. CT scan demonstrated a multiple concentric structure in the ileocecal region. Colonoscopy showed a polyp-like tumor arising from the expected location of the appendix, with a dimple at the top. Barium enema study revealed a submucosal tumor-like filling defect in the cecum with non-filling of the appendix. A diagnosis of intussusception of the appendix (IA) was made. During the follow-up, IA reduced spontaneously. The present case report is the first description of IA in a patient on hemodialysis therapy. Furthermore, spontaneous reduction of IA is indeed rare.
