The patient was a 66-year-old woman, G2P2. The patient presented a chief complaint of irregular postmenopausal bleeding 1 month ago. A transvaginal ultrasonography showed that bilateral ovaries were not enlarged and uterine endometrium was thickened, measuring at 9 mm. As a result of endometrial curettage, the simple endometrial hyperplasia was revealed. A blood examination showed an elevated estradiol level of 67 pg/mL, an elevated level of testosterone 0.64 ng/mL, and a slightly suppressed follicle-stimulating hormone (FSH) level of 34.86 mIU/mL. We conducted laparoscopic hysterectomy and bilateral salpingo-oophorectomy because the patient strongly suggested less invasive surgery. The result of pathological diagnosis was Sertoli-Leydig cell tumor (SLCT) in moderately differentiation. A blood examination after a month postoperatively revealed an elevated FSH level of 85.59 mIU/mL, depressed estradiol level of less than 10 pg/mL, and testosterone level of less than 0.03 ng/mL. There was no evidence of recurrence in the first year of follow-up.

To prevent aggressive surgery it is important to recognize that this tumor is a benign and unusual appearing variant of leiomyoma. A fertility-sparing surgical procedure should be considered if the patient wishes to preserve her fertility.

BackgroundEosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis of unknown cause involving the brain and accompanied by prominent eosinophilia. Intracardiac thrombosis is a major cardiac complication of EGPA that may cause thromboembolism.Case presentationA 53-year-old man presenting with abulia (consciousness disturbance) and left upper limb paralysis was admitted to our hospital. His case was complicated by penetrating branches, small vessel infarcts, and endocardial thrombosis in the right and left ventricle. Cardiomyopathy was also observed. Sixteen days after admission, the patient died from intracranial hemorrhage. Brain autopsy revealed two major findings: 1) large hemorrhagic infarction caused by cardiac embolism; and 2) granuloma and eosinophil infiltration. Vasculitis was accompanied by eosinophil infiltration in the cortical blood vessels and granuloma.ConclusionsIn this case study, we report autopsy findings of brain infarction in a patient with EGPA and endocardial thrombosis. The brain infarction was caused by the cardiac embolisms and vasculitis.
