A 40-year-old woman was admitted to our hospital because of left hemiplegia. She was affected with myocardial infarction and cerebral infarction. Echocardiogram revealed that the aortic and mitral valves had thick and uneven echoes suggesting vegetations. Judging from the finding that repeated blood cultures were negative, we had considered in her lifetime that myocardial and cerebral infarctions were due to embolization associated with nonbacterial thrombotic endocarditis (NBTE). At autopsy, histological diagnosis was made as ovarian cancer with disseminated intravascular coagulation. From the clinical course and the histological findings, we diagnosed this patient as NBTE.

Group B streptococcus (Streptococcus agalactiae) is a common etiology of bacteremia among adults. Pyomyoma is a rare infectious complication of uterine leiomyomas. We report the case of a diabetic postmenopausal woman with a giant pyomyoma simulating an ovarian cancer. It was associated with S. agalactiae endocarditis and deep venous thrombosis of the right external iliac and femoral veins. Treated initially with intravenous penicillin, amikacin, and anticoagulation, the patient later had abdominal hysterectomy with an uneventful recovery. We also review the cases of pyomyoma reported since 1945. Of 14 cases described (including ours), mortality was 21%. Endocarditis was never reported in association with pyomyoma. The presence of bacteremia and a leiomyoma should raise suspicion for this disease.

Interleukin-6 (IL-6) is reportedly increased in serum and CSF from acute stroke patients. However, the cellular origin and possible role of IL-6 in CNS after stroke are unclear. We describe a woman with recurrent stroke, disseminated intravascular coagulation (DIC) and non-bacterial thrombotic endocarditis (NBTE) caused by ovarian cancer (Trousseau syndrome). The patient died 50 days after the final episode of cerebral embolism. The immunohistochemical study revealed IL-6 protein to have been expressed both in cerebral neurons spared from ischemic insult and in epithelial cells of the ovarian tumor. We speculate that IL-6 produced in ovarian cancer may be associated with the hypercoagulable state and the development of NBTE in this patient. In contrast, IL-6 induction in cerebral neurons may contribute to the survival of these neurons after a stroke.

A cerebrovascular thromboembolic event may precede the identification of cancer, and be the first clinical evidence of an underlying malignancy. The malignancy can cause either nonbacterial thrombotic endocarditis or hypercoagulable state, both of which may have clinical manifestions such as thrombotic or embolic occlusion of multiple major cerebral vessels. We present three cases with unusual cerebrovascular events. The first case is a 62-year-old woman who was admitted due to acute left limbs weakness and consciousness disturbance. Brain computed tomographic (CT) scan showed right middle cerebral artery (MCA) and posterior cerebral artery (PCA) infarctions with uncal herniation. The second case is a 44-year-old woman who was hospitalized due to acute bilateral limb weakness and consciousness disturbance. Bilateral MCA, left PCA, anterior cerebral artery (ACA) infarctions and deep vein thrombosis in the left leg were diagnosed. The third case is a 63-year-old man who developed sudden onset of right hemiplegia and consciousness disturbance. Brain CT scan showed bilateral MCA and left ACA infarction. The results of a series of examinations including biochemistry, lipid profile, carotid duplex, and transthoracic and transesophageal echocardiography were unremarkable. All patients had positive disseminated intravascular coagulation (DIC) tests with elevated D-dimers and fibrinogen degradation products (FDP). Further systemic evaluation for malignancy revealed ovarian cancer in the first patient, endometrial carcinoma in the second patient, and adenocarcinoma of lung in the third patient. They all died of the underlying malignancy. Because the hemostatic system can be altered by malignancy, intravascular coagulation abnormalities of these malignancy-related strokes may be disclosed by laboratory assays of hemostasis.

Non bacterial thrombotic endocarditis is the most frequent cause of ischemic stroke in cancer patients. Up to 9% of autopsies of cancer patients show non infectious valvular masses. However, bivalvular involvement is not frequently occurring in 9% of non bacterial thrombotic endocarditis. We report a patient with ovarian cancer who presented aphasia. The MRI was compatible with cerebral ischemia. The transthoracic echocardiogram was normal and a transesophageal echocardiogram showed vegetations in aortic and mitral valves. We emphasize the importance of suspecting non bacterial thrombotic endocarditis in patients with cancer and systemic embolism and the low frequency of bivalvular involvement.

Candida spp is a common pathogen of nosocomial infections that has increased in recent decades, with mortality rates close to 40% in cases of systemic candidiasis. One type of presentation is infective endocarditis, which, by its prolonged need for treatment, represents a constant challenge for clinicians. We describe a 36-year-old woman, recently diagnosed with ovarian cancer, who developed aortic valve infective endocarditis caused by Candida parapsilosis and who was treated with oral antifungal medication, with no surgical intervention required.

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.
