Spontaneous dissection of the brachiocephalic artery is rare, and there is insufficient evidence for optimal treatment. We herein report a case of ischemic stroke due to spontaneous dissection of the brachiocephalic to the right common carotid artery. The patient was treated medically but died suddenly 18 days after the onset because of aortic dissection. Although almost all reported cases of spontaneous dissection of the brachiocephalic artery have had good outcomes with medical management, it is important to note that sudden development of aortic dissection might occur, even without initial findings suggestive of this condition.

Case Reports
A Case of Pembrolizumab-induced Focal Pancreatitis Diagnosed by Endoscopic Ultrasound-guided Fine-needle Aspiration.
A 69-year-old man with advanced non-small-cell lung cancer was treated with pembrolizumab for 4 months. Three months after pembrolizumab was discontinued, computed tomography showed enlargement of the pancreatic head, with hypoattenuating areas in the pancreatic head to body. ⋯ Endoscopic ultrasound-guided fine-needle aspiration showed inflammatory cell infiltration in the stroma but no neoplastic lesions. CD8-positve T cells were dominant over CD4-positive T cells in the infiltrating lymphocytes, and the patient was diagnosed with pembrolizumab-induced pancreatitis.

A patient with follicular lymphoma treated with obinutuzumab and bendamustine experienced prolonged coronavirus disease-2019 (COVID-19). One month after the symptoms transiently improved, the patient experienced exacerbated COVID-19 symptoms. ⋯ A careful observation to detect any subsequent relapse of COVID-19 symptoms is necessary in immunocompromised patients. Chemotherapy should be based on the disease status and type of lymphoma.

KMT2B-related dystonia (DYT28, DYT-KMT2B) is an inherited dystonia that generally begins in the lower limbs during childhood and evolves into generalized dystonia. We herein report a case of adult-onset DYT28 with dystonic tremor. ⋯ Although the disease generally develops during childhood, we diagnosed the woman with DYT28, as genetic testing revealed a mutation in KMT2B. Adult-onset patients with DYT28 might also show uncommon symptoms as well as DYT-TOR1A (DYT1).
