A 56-year-old man presenting with abdominal pain had an elevated serum immunoglobulin 4 (IgG4) concentration. Computed tomography angiography revealed a celiacomesenteric trunk aneurysm with wall. After admission, the celiacomesenteric trunk aneurysm grew rapidly along with wall thinning. Emergency transcatheter arterial embolization was completed using detachable coils. After transcatheter arterial embolization, the patient's abdominal pain disappeared completely. Steroid administration, which continues to the present day, was started 1 month after the transcatheter arterial embolization. No clinical symptoms associated with recurrent arteritis or other IgG4-related disease have been confirmed.
