We herein report the first case of dyspnea with hemidiaphragm elevation in a 68-year-old woman with active giant cell arteritis (GCA), including successful treatment. Contrast-enhanced computed tomography showed a reduced density of the left ophthalmic artery and the left superficial temporal artery with increased soft tissue compared to the other side, indicating that the GCA had flared up and suggesting that the hemidiaphragm elevation might be caused by vasculitis-associated ischemia of the right phrenic nerve. Hemidiaphragm paralysis due to vasculitis-associated ischemia in patients with GCA needs to be distinguished from local infection, tumors, and hepatomegaly, which are the major causes of hemidiaphragm elevation.

A 74-year-old woman developed acute severe colitis after receiving her sixth mRNA vaccine against coronavirus disease 2019 (COVID-19). On the day after vaccination, she experienced bloody diarrhea, abdominal pain, and high-grade fever. Laboratory tests revealed leukocytosis and increased C-reactive protein. ⋯ Her symptoms and laboratory findings improved immediately after the initiation of prednisolone therapy. Pre-discharge total colonoscopy revealed mucosal repair in most of the colon. Clinicians should acknowledge that severe acute colitis can occur after COVID-19 vaccination.

Case Reports
Case of Pulmonary Tumor Embolism due to Oropharyngeal Carcinoma Diagnosed by a Transbronchial Lung Biopsy.
Pulmonary tumor embolisms (PTEs) are primarily caused by adenocarcinoma. However, only a few cases of oropharyngeal carcinoma have been reported. ⋯ A transbronchial lung biopsy revealed a mass of squamous tumor cells forming emboli in the small vessels, resulting in the diagnosis of PTE due to oropharyngeal carcinoma. Therefore, PTE should be considered for patients with a history of hypoxia.

Successful Treatment of Bilocular Walled-off Necrosis with Transmural Naso-cyst Continuous Irrigation: A Case Report.
Recently, transmural naso-cyst continuous irrigation (TNCCI) has been reported as an effective and safe treatment for walled-off necrosis (WON). We herein report a case of bilocular WON that was successfully treated with TNCCI. ⋯ Subsequently, a lumen-apposing metal stent (LAMS) was placed in the main cavity and TNCCI was successfully performed in the subcavity. TNCCI with LAMS was effective in treating bilocular WON.

A 79-year-old woman developed herpes zoster ophthalmicus (HZO) with a vesicular rash on the nasal root, which developed soon after intravenous acyclovir therapy. Although varicella zoster virus DNA was undetectable in the cerebrospinal fluid, she presented with ophthalmoplegia without optic nerve dysfunction 32 days after the onset of HZO. ⋯ Ophthalmoplegia did not immediately respond to these therapies but resolved 4 months later. We should be aware that ophthalmoplegia can occur, even after HZO and meningitis are completely treated.
