Abstract:
We herein report a patient with giant cell arteritis (GCA) who developed pneumatosis intestinalis (PI) while she was in a clinically sustained remission phase. A 79-year-old woman with GCA involving the thoracic aorta and its first branches to the posterior tibial arteries had been treated with high-dose prednisolone. Nine weeks after initiating treatment and while in clinically sustained remission with a normal CRP level, PI and pneumoperitoneum were incidentally found during scheduled positron emission tomography-computed tomography, which also revealed slight residual inflammation of GCA. This is a very rare case of PI complicated by GCA, and we discuss the possible relationships.
