Imaging studies failed to identify the embolic source of the stroke, although a lesion protruding into the proximal portion of the left internal artery lumen was demonstrated on carotid ultrasonography. Specifically, the protruding lesion was a crescent-shaped membranous structure however, we did not initially regard the protruding lesion as the embolic source. Therefore, he was treated with warfarin and followed in the outpatient clinic. Serial carotid ultrasonographic examinations performed at each outpatient clinic visit revealed no structural changes in the crescent-shaped membranous structure, but a thrombus distal to the membranous structure was detected 6 months after the stroke onset in spite of warfarin therapy. At that time, we determined that the protruding lesion was a carotid web and the embolic source of the stroke. He underwent a carotid endarterectomy, the warfarin was discontinued, and he has had no recurrent strokes. A carotid web is an important embolic source of an ischemic stroke, but has not been widely reported. It is essential to recognize a carotid web as a potential embolic source to prevent stroke recurrence.","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135443099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 70-year-old man was admitted to our hospital with heart failure. He had a persistent fever and the inflammatory response increased. Serum β-D-glucan level was elevated, and Candida albicans was identified from blood culture. He was diagnosed with a fungal infection. A central venous catheter had been inserted into the right internal jugular vein for 3weeks. The ultrasonography showed a full mass image of 6 × 5mm which was attached to a string-like organizing thrombus of approximately 25mm long in the right internal jugular vein. The echogram presented a spherical and smooth outline, and slightly heterogeneous inside of the mass with scattered vesicular structures. We attempted to retrieve a foreign body using a catheter under ultrasound guidance. However, it cannot be detached from the vessel wall. Next, surgical resection was planned under intraoperative ultrasound examination, however, the surgical procedure was not performed because his general condition deteriorated. Fortunately, the level of β-D-glucan decreased after administration of amphotericin B and the foreign body, suspected fungal mass, became smaller on ultrasonography. We experienced a suspected patient with a fungal mass in the right internal jugular vein. Ultrasonography was useful in diagnosis, treatment or follow-up.","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135442741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present an unusual 79-year-old man with cerebral embolism caused by CPF in CR. The patient presented with right upper limb paresis and was diagnosed with left centrum ovale infarction. Atrial fibrillation and severe stenosis of the cerebral and carotid artery were not found in various examinations. Although transthoracic echocardiography showed no abnormalities, transesophageal echocardiography (TEE) revealed a mobile string-like structure measuring approximately 11 mm at the tip of the CR. We suspected a thrombus attached to the CR, and anticoagulation therapy was administered, however the structure did not dis-appear. Therefore, the patient was diagnosed as cardiac tumor and underwent tumor excision and surgical clo-sure of the left atrial appendage. The tumor was confirmed to be CPF on histopathology. Warfarin therapy was continued, and there was no recurrence of tumor or cerebral embolism at 4 months after surgery. CPF should be considered in cryptogenic stroke, especially in embolic stroke of undetermined sources cerebral embolism.","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"21 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89495433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
