High Detection Rate of Atrial Fibrillation With Insertable Cardiac Monitor Implantation in Patients With Cryptogenic Stroke Diagnosed by Magnetic Resonance Imaging
Background: Detection and treatment of atrial fibrillation (AF) is a major goal in preventing secondary stroke. Insertable cardiac monitors (ICMs) are available for diagnosis of arrhythmia monitoring in patients with cryptogenic stroke. Magnetic resonance imaging (MRI)-based diagnostic evaluation for acute ischemic stroke subtype classification is common in Japan and can be useful for specific diagnosis of cryptogenic stroke. Purpose: We aimed to investigate the detection rate of AF with an ICM in patients with cryptogenic stroke who were diagnosed by MRI.

Cerebral Autosomal Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalopathy Associated With a Novel In-Frame Mutation in the NOTCH3 Gene in a Japanese Patient
Here, we report a case involving a 67-year-old Japanese woman with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) associated with a novel in-frame complex rearrangement in the NOTCH3 gene. The patient had gradually developed cognitive impairment since the occurrence of an ischemic stroke at the age of 53 years. Her mother had a history of stroke and dementia. Fluid-attenuated inversion recovery magnetic resonance imaging of the brain showed hyperintense lesions in the bilateral temporal poles, external capsules, and periventricular white matter accompanied by multiple c...

Rectus Sheath Hematoma Following Intravenous Thrombolysis With Recombinant Tissue Plasminogen Activator for Cerebral Infarction: A Case Report
A 76-year-old Japanese man was admitted to our department because of aphasia and right hemiparesis. Brain magnetic resonance imaging showed cerebral infarction caused by occlusion of the left middle cerebral artery, and alteplase therapy was started. Thrombectomy was subsequently performed, resulting in recanalization. On day 4 after admission, he complained of epigastric pain when coughing. On day 8, contrast-enhanced computed tomography showed a left abdominal rectus sheath hematoma without extravasation.

Recurrent Cerebral Venous Thrombosis Treated with Direct Oral Anticoagulants in a Japanese Man with Hereditary Protein C Deficiency
We herein report a case involving a 32-year-old Japanese man with recurrent cerebral venous thrombosis due to hereditary protein C deficiency. He was admitted to our hospital with impaired consciousness. Brain magnetic resonance imaging demonstrated high intensities diffusely along the bilateral sulci and magnetic resonance venography revealed left transverse sinus and superior sagittal sinus stenoses. His father had a history of cerebral infarction and venous thrombosis. The protein C activity level examined by chromogenic synthetic substrate assay was markedly reduced.
