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.

Case Reports
Successful Treatment of Chylothorax and Chylopericardium by Radiotherapy in Lung Cancer.
A 58-year-old man was diagnosed with stage IVB lung adenocarcinoma in the right upper lobe and underwent systemic chemotherapy. Seven months after the diagnosis, large left pleural and pericardial effusion was detected. ⋯ After radiotherapy, the chylothorax and chylopericardium gradually resolved, and no further chyle leaks were identified on follow-up computed tomography. This case indicates that radiotherapy can be used to ameliorate lung cancer-related chylothorax and chylopericardium.

We herein report a 60-year-old woman who experienced severe flare of rheumatoid arthritis (RA) and Epstein-Barr virus (EBV) positivity following administration of the messenger ribonucleic acid (mRNA)-type severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine. Since 40 years old, she had been in long-term remission of anti-citrullinated protein antibody-positive RA. ⋯ Tocilizumab was introduced to treat RA. The RA disease activity disappeared, and anti-EA DR IgG and EBV-DNA became negative.

Mesenteric hematoma is an uncommon condition caused by focal bleeding in the mesenteric vessels. Hematomas are related to trauma, pancreatitis, arteriopathy, and the use of antithrombotic agents. ⋯ We herein report a case with a large mesenteric hematoma that caused duodenal stenosis by compressing the third portion of the duodenum. Stenosis was successfully ameliorated after long-term use of a double elementary diet tube.

Case Reports
Atrial Fibrillation-triggered Ventricular Fibrillation in a Patient with Early Repolarization Syndrome.
A 54-year-old man with early repolarization syndrome (ERS) implanted with an implantable cardioverter-defibrillator (ICD) developed persistent atrial fibrillation (AF) three years after the implantation. Similarly, the remote monitoring system begun frequently detecting ventricular fibrillation (VF) and polymorphic ventricular tachycardia (PVT). Longer RR intervals were repeatedly observed just before the initiation of PVT/VF. Catheter ablation for AF successfully diminished both the PVT and VF events.
