A 44-year-old woman was admitted to our hospital with a fever, dizziness, and gait disturbance after undergoing allogeneic hematopoietic stem cell transplantation for acute myeloid leukemia followed by graft-versus-host disease. She presented with cerebellar ataxia, nystagmus, and numbness of the lower extremities. Brain magnetic resonance imaging and perfusion scintigraphy showed progressive cerebellar involvement. ⋯ Anti-ganglioside antibodies were detected, but their levels did not follow the patient's clinical course. The patient did not respond sufficiently to steroids or other immunotherapies. We herein report the clinical characteristics of this case and a literature review.

Review Case Reports
Duodenal Heterotopic Pancreas with a Large Retention Cyst: A Case Report and Literature Review.
A 75-year-old man was referred to our hospital with a suspected pancreatic cyst. Imaging tests revealed a 3-cm cystic lesion located ventrally in the duodenal bulbus, which was suspected to be a duplication cyst with its muscularis propria contiguous to that of the duodenum. ⋯ The diagnosis was a large, non-malignant retention cyst. Inflammation due to impaired outflow of pancreatic juice from the HP was identified as the cause of cyst enlargement.

Review Case Reports
Lung and Cerebral Nocardiosis Caused by Nocardia elegans in a Lung Transplant Recipient: A Case Report and Literature Review.
Patients after lung transplantation are at risk for Nocardia infections. We herein report a case of lung and cerebral nocardiosis caused by Nocardia elegans, a rare species of Nocardia, in a lung transplant recipient. ⋯ A literature review of N. elegans infections showed that 12 of 14 cases (85.7%) were reported from East Asia, particularly Japan (9 cases, 64.2%). The lungs were the predominant site (12/14 cases, 85.7%), and most of the cases were susceptible to ST (9/10 cases, 90%).

Review Case Reports
Epidural Spinal Cord Compression as the Presenting Manifestation of Acute Myeloid Leukemia: A Case Report and Literature Review.
We herein report a rare case of spinal cord compression due to epidural involvement of acute myeloid leukemia (AML). A 14-year-old boy presented with a 7-day history of back pain, paraplegia and hypoesthesia. Contrast-enhanced computed tomography revealed an epidural mass. ⋯ Chemotherapy was initiated, and complete remission was achieved. Neurological sequelae remained after the treatment. Based on the present and previous reports, spinal cord compression from epidural AML involvement may progress rapidly.

Review Case Reports
Subendocardial Ischemia Caused by Acute Severe Aortic Regurgitation Due to Aortic Root Dissection: A Case Report and Literature Review.
Electrocardiogram (ECG) findings showing ST-segment depression in a wide range of leads and ST-segment elevation in aVR are found in patients with acute coronary syndrome with multivessel coronary lesions and left main trunk lesions. A 64-year-old man with a history of eosinophilic granulomatosis presented with chest pain and dyspnea. Although an ECG showed the above findings, he was diagnosed with acute severe aortic regurgitation (AR) complicating aortic root dissection and successfully underwent urgent Bentall operation. These ECG findings indicated that acute severe AR caused subendocardial ischemia.
