Staphylococcus lugdunensis is part of the native flora in the inguinal region of the body. Inguinal surgeries, such as vasectomy, place carriers of this aggressive pathogen at risk for contamination. Native-valve endocarditis caused by coagulase-negative S. lugdunensis has a rapid and complicated clinical course. The pathogenicity of this organism is not limited to cardiac valvular destruction. We report the case of a 36-year-old man who presented with S. lugdunensis endocarditis, dysarthria, and hemiparesis 5 weeks after a vasectomy. To our knowledge, this is the first report of embolic stroke caused by S. lugdunensis endocarditis. In addition, we discuss the relevant medical literature.

A 52-year-old woman was admitted to our hospital for acute right hemi-paresis, left homonymous hemianopia, and fever. Magnetic resonance imaging of the brain showed multiple cerebral infarctions and transesophageal echocardiography (TEE) revealed a vegetation on the posterior leaflet of her mitral valve. Mitral valve repair was performed under a diagnosis of infective endocarditis (IE). Further multiple cerebral infarctions occurred on the 11th postoperative day, resulting in left hemiplegia and dysarthria. TEE revealed vegetations on her mitral valve and mitral valve replacement (MVR) was performed. Microscopic examination of the resected valve showed mild lymphocytic infiltration, but no bacterial or fungal organisms were detected. On the 66th day after the initial surgery, she developed deep vein thrombosis and acute pulmonary embolism. Abdominal computed tomography showed a huge ovarian tumor, and TEE demonstrated vegetations on the left atrial wall, the aortic valve, and the mechanical valve immobilizing one of the leaflets. The patient was finally diagnosed as having Trousseau syndrome caused by an ovarian tumor and non-bacterial thrombotic endocarditis( NBTE). Three months after the initial operation, redo MVR was performed and aortic valve vegetations were removed. Four days later, the ovarian cancer was resected. Her postoperative course was uneventful and she was discharged on foot on the 143rd day after the initial operation. NBTE caused by malignancy is rare but must be considered when managing endocarditis.

We report a case of multiple embolic cerebral infarcts associated with nonbacterial thrombotic endocarditis (NBTE) in a patient with adenomyosis. The patient presented with dysarthria, left perioral sensory change, and left-hand weakness. Magnetic resonance imaging revealed multiple vascular territory infarctions involving the bilateral cerebellum and the right precentral gyrus. Magnetic resonance angiography was normal. d-Dimer, carbohydrate antigen (CA) 19-9, and CA125 levels were elevated. Abdominal and pelvic computed tomography with iodine contrast enhancement revealed a huge adenomyosis with left ovarian cyst. Transesophageal echocardiography (TEE) with agitated saline injection test demonstrated shaggy vegetation at the coapting edge of both mitral leaflets and mitral regurgitation. A diagnosis of NBTE was established and treatment with anticoagulation was initiated. Two weeks later, the thrombi reduced significantly on follow-up TEE and transthoracic echocardiography. The patient underwent an abdominal hysterectomy with bilateral salpingo-oophorectomy, and pathological specimens confirmed adenomyosis. The possibility that adenomyosis can be associated with NBTE suggests one of the underlying thromboembolic mechanisms in adenomyosis. Clinicians should be aware of the potential thromboembolic risk of adenomyosis. Further reporting of similar cases is needed to confirm the thromboembolic mechanism.

Cardiac myxoma typically is thought to be a slow-growing, benign primary. Atrial myxomas can lead to many complications and can also mimic mitral stenosis, infective endocarditis, and other vascular diseases associated with systemic embolization. A 75-year-old woman with a history of lung cancer (pT1cN1, adenocarcinoma), atrial fibrillation, and a cerebral infarction presented with dysarthria and visual disturbances. In our case, we had to consider some questionable issues with the left atrial mass, and whether the recurrence of cerebral events was due to the thrombotic material in the left atrium or from locally recurrent lung cancer from the stump margin of the previously resected left superior pulmonary vein. We present a case with a rapidly-growing left atrial myxoma with a growth rate of 12.60 mm/month, rather than a thrombus or local recurrence of tumor under a medication of non-VKA oral antagonists.

Infectious intracranial aneurysm (IIA), a rare type of cerebral aneurysm, is often observed in patients with infective endocarditis. Hemorrhage or infarction often occurs; however, the presentation of both hemorrhagic and ischemic components is rare. A 41-year-old man with progressive motor weakness, dysarthria, and severe headache was admitted to our hospital. Brain computed tomography scan revealed a scanty subarachnoid hemorrhage (SAH), and diffusion magnetic resonance imaging confirmed acute cerebral infarction around the external capsule and insular lobe. A digital subtraction cerebral angiogram revealed an obstruction in the middle cerebral artery (MCA). The patient's neurological symptoms improved remarkably on the fifth day, and a follow-up angiogram revealed recanalized MCA with pseudoaneurysm, which was not observed on the previous angiogram. A blood culture result confirmed bacteremia, and the patient was then diagnosed with infective endocarditis. The pseudoaneurysm was treated with anastomosis of the superficial temporal artery and MCA with trapping of the parent artery. He was discharged with no neurological deficits. Herein, we present a patient with IIA, who sequentially developed SAH and cerebral infarction, and underwent extracranial-intracranial bypass with trapping of the parent artery. Although the treatment strategy for IIA is controversial, the treatment plan should be cautiously discussed with the patient. In addition, the assessment of an underlying infectious disease is required.
