A 44-year-old woman with a subacute onset of an altered mental status, urinary retention, and fluctuating blood pressure was initially diagnosed with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis, meeting the criteria of Graus et al. Cardiac arrest occurred, which required pacemaker placement. ⋯ Enteroviruses or autoimmune encephalitis-associated autoantibodies were not detected. We herein report a case of acute flaccid myelitis with profound psychiatric symptoms and dysautonomia, resembling NMDAR encephalitis.

Case Reports
Effect of Thyrocervical Artery Embolization for Mediastinal Hemangioma with Pleural Effusion.
A 72-year-old man was admitted to our hospital with a complaint of breathlessness. Computed tomography revealed a tumor with intense early enhancement and pleural effusion. Although the pleural effusion was not bloody, the tumor showed a hypervascular area on angiography. ⋯ After embolization, chest radiography revealed decreased pleural effusion. The tumor was resected and pathologically diagnosed as a mediastinal cavernous hemangioma. To our knowledge, mediastinal hemangiomas with pleural effusion are extremely rare; thus, this is the first report of reduced pleural effusion in mediastinal hemangiomas after artery embolization.

A 78-year-old male was admitted to the hospital with acute renal failure and generalized erythema after starting dapagliflozin 10 mg/day for chronic kidney disease (CKD). A skin biopsy revealed superficial perivascular dermatitis with eosinophils. ⋯ The patient's renal function improved, and erythema disappeared. To our knowledge, this is the first report of DRESS caused by dapagliflozin, and the patient was successfully treated with prednisolone.

Immune checkpoint inhibitors can cause a range of immune-related adverse events, including myositis, Takotsubo cardiomyopathy, and myasthenia gravis. We herein report a rare case of a 78-year-old man with concurrent durvalumab-induced myositis, Takotsubo-like morphological changes caused by myocarditis, and myasthenia gravis. ⋯ However, he subsequently achieved successful recovery after the administration of intravenous immunoglobulin, plasmapheresis, and high-dose steroids. We advocate vigilant neurological monitoring of patients with immune checkpoint inhibitor-induced myositis, including the assessment of ptosis and other relevant signs, so that prompt treatment can be initiated at the time of emergence or progression of immune checkpoint inhibitor-induced myasthenia gravis.

A 34-year-old transgender woman presented with ventricular tachycardia and was diagnosed with takotsubo cardiomyopathy. Further evaluation revealed an underlying diagnosis of multiple sclerosis (MS) with brainstem lesions that may have triggered takotsubo cardiomyopathy. In this report, we also systematically reviewed published cases of takotsubo cardiomyopathy and MS and found that basal type takotsubo cardiomyopathy was the most common, and most patients presented with brainstem involvement of MS. An awareness of these associations by physicians, along with multidisciplinary collaboration, may facilitate the early diagnosis and improve the prognosis of these patients.
