We encountered a 60-year-old man who had been diagnosed with heart failure of valvular disease and infective endocarditis; he was being treated with intravenous antibiotics and diuretics. On the 12th hospital day, he suddenly lost consciousness; computed tomography showed a right-sided huge subdural hematoma (SDH) with brain herniation. ⋯ A massive SDH was noted at autopsy, and microimaging demonstrated ruptured infective arteritis, without aneurysm, on the surface of the culprit lobe. Acute SDH usually occurs after head trauma, but an area of nonsaccular aneurysmal arteritis can also result in acute SDH.

We herein report a 34-year-old man who presented with recurrent palpitations that occurred while swallowing solid food. Holter monitoring revealed atrial tachycardia (AT) while eating. ⋯ The AT disappeared postoperatively. This case demonstrates that a mediastinal nodule can cause swallowing-induced AT.

A 46-year-old woman with lung cancer who received chemotherapy was admitted to our hospital for lower-lobe bilateral ground-glass opacity (GGO). GGO developed after the lung cancer diagnosis, deteriorated after the initiation of osimertinib, and incompletely decreased after interrupting osimertinib; therefore, flexible bronchoscopy was performed. Transbronchial lung biopsy histology and anti-granulocyte/macrophage colony-stimulating factor autoantibody positivity revealed autoimmune pulmonary alveolar proteinosis (aPAP) that did not require treatment. This rare case of aPAP comorbid with lung cancer suggested that using PAP findings to differentiate from drug-induced lung injury or lymphangitis is difficult and that osimertinib was suspected to exacerbate aPAP.

A 59-year-old woman presented to our hospital with liver dysfunction. Imaging revealed multiple lesions in the liver. The patient was diagnosed with peliosis hepatis using percutaneous and laparoscopic biopsies. ⋯ Her condition progressed rapidly, and she died two weeks after the diagnosis. Diagnosis of hepatic angiosarcoma in the early stages is difficult. It should be noted that hepatic angiosarcoma may be associated with the development of peliosis hepatis.

Case Reports
Asymptomatic Coarctation of the Aorta in Adults with Preserved Exercise Capacity: A Case Report.
We herein report a case of coarctation of the aorta (CoA) in an asymptomatic adult who had a preserved exercise capacity. A 56-year-old man with mild hypertension exhibited left ventricular hypertrophy on an electrocardiogram during an annual medical checkup. ⋯ He refused surgical repair and has been asymptomatic for five years. This case is of special interest, as CoA is usually rarely noticed during adulthood if there are no severe congenital anomalies, and in addition, this patient had good exercise capacity.
