There are few cases describing the association of eosinophilia with hypercalcemia, and drug-induced eosinophilia with hypercalcemia has not been reported. A 74-year-old man had been diagnosed with asthma 4 months earlier. He was admitted due to eosinophilia with hypercalcemia. ⋯ After the discontinuation of clopidogrel, the eosinophilia with hypercalcemia, lung nodule and mediastinal lymphadenopathy improved. Clopidogrel-induced eosinophilia can potentially cause hypercalcemia. Obtaining a detailed clinical history is important in diagnosing the cause of eosinophilia.

Large Gallstones Stacked Together in the Common Bile Duct after Choledochojejunostomy: A Case Report.
A 65-year-old man had a history of cholecystectomy and treatment for cholelithiasis with a common bile duct incision. Owing to frequent cholangitis, he underwent choledochojejunostomy. ⋯ Percutaneous transhepatic cholangioscopy using a SpyGlass™ DS (Boston Scientific, Marlborough, USA) showed gallstones and bile sludge in the bile ducts, but no tumors were noted. Electrohydraulic shockwave lithotripsy with double-balloon enteroscopy enabled complete stone removal; a direct visual biopsy with peroral cholangioscopy showed no malignancy in the bile duct.

A 69-year-old man was diagnosed with immunoglobulin (Ig) G4-related disease (IgG4-RD) at 62 years old. At that time, he had high serum IgG4 levels and bilateral submandibular gland swelling on CT; thus, a gland biopsy was performed. ⋯ The patient was subsequently followed up without treatment. His forced vital capacity and radiological findings progressively deteriorated, consistent with UIP pattern interstitial lung disease but different from a lung lesion of IgG4-RD.

Significance of Cortical Ribboning as a Biomarker in the Prodromal Phase of Sporadic Creutzfeldt-Jakob Disease.
A 63-year-old woman who presented for orofacial dystonia showed cortical ribboning, a typical MRI finding in sporadic Creutzfeldt-Jakob disease (sCJD). However, real-time quaking-induced conversion (RT-QuIC), the most sensitive method for an early diagnosis of sCJD, was negative. ⋯ The cerebral blood flow showed a decrease in the cerebral cortex (especially in the supramarginal gyrus) consistent with cortical ribboning, but an increase in the basal ganglia, probably involved in orofacial dystonia. Cortical ribboning on MRI might be a better biomarker than RT-QuIC in the prodromal phase of sCJD.

Course of Cardiac Magnetic Resonance Imaging Findings in Acute Myocarditis after COVID-19 mRNA Vaccination.
Myocarditis is being increasingly reported as a rare complication of coronavirus disease 2019 (COVID-19) mRNA vaccines. We herein report a case of myocarditis following COVID-19 mRNA vaccination in a man. ⋯ Follow-up CMRI performed six months later revealed improvement in the myocardial edema and LGE findings. CMRI is a useful non-invasive imaging modality for making an initial diagnosis as well as for follow-up in cases of myocarditis after COVID-19 mRNA vaccination.
