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.

Review Case Reports
Atezolizumab-induced Encephalitis in a Patient with Hepatocellular Carcinoma: A Case Report and Literature Review.
We herein report a case of encephalitis in a 42-year-old woman with hepatocellular carcinoma following atezolizumab plus bevacizumab therapy. After two weeks of treatment, she was admitted for a high fever, impaired consciousness, and convulsive seizure refractory to diazepam. Magnetic resonance imaging revealed a hyperintense splenial lesion. ⋯ Steroid pulse therapy improved the fever and seizure. However, her incomplete right-sided paralysis and aphasia persisted. This is the first case report of encephalitis caused by atezolizumab plus bevacizumab therapy for hepatocellular carcinoma.

Kikuchi disease, also called histiocytic necrotizing lymphadenitis, is an idiopathic and generally self-limiting disease affecting young adults and children. Kikuchi disease does not commonly manifest neurological complications at its initial presentation. We herein report two cases of Kikuchi disease that initially presented with aseptic meningitis and encephalitis rather than the more common signs of lymphadenopathy, rash, and arthritis. ⋯ Both patients improved after treatment with steroids. Kikuchi disease occasionally affects the central nervous system, to which lymphadenitis may be observed subsequently. A repeated, careful physical examination of the cervical lymph nodes may be helpful for the diagnosis.

Case Reports
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.

Case Reports
Acute Exacerbation of Anemia with Parvovirus B19 Infection One Year after Sleeve Gastrectomy for Severe Obesity.
Pancytopenia due to malnutrition sometimes occurs after gastric bypass but is rare after sleeve gastrectomy. A 35-year-old patient underwent sleeve gastrectomy for severe obesity. ⋯ In addition, IgM antibody against parvovirus B19 was detected, followed by IgG antibody. Parvovirus B19 infection was suggested to be involved in the rapid progression of anemia in this malnourished patient after bariatric surgery.
