Angiocentric glioma (AG) is an extremely rare tumor that often develops in adolescents. Awake surgery for AG occurring in the eloquent area has not been reported to date. We report a case involving a righthanded 15-year-old boy with AG. He presented with a first-time generalized tonic-clonic seizure and was rushed to the local hospital. CT of the head indicated a left frontal low-density mass with no calcification. He was subsequently referred to our hospital. Comparison with a CT scan obtained two years prior due to mild head trauma indicated that the lesion showed a trend toward enlargement. The lesion was located in the anterior and lateral portions of the primary motor cortex, and MRI showed homogenous hypointensity on T1-weighted and hyperintensity on T2-weighted images. Contrast-enhanced MRI showed a linear contrast effect. The patient underwent awake surgery with successful intraoperative brain mapping and total resection, and brain function was preserved. Pathological analysis revealed AG. He returned to his normal life and has shown no recurrence without additional treatment for 2 years. Thus, awake surgery for complete tumor resection while preserving brain function is effective and safe even in adolescents with AGs.

A 73-year-old woman presented at our hospital with dyspnea. Echocardiography showed severe aortic stenosis and a coronary angiography revealed right coronary artery disease. Therefore, we performed aortic valve replacement (AVR) and coronary artery bypass grafting (CABG) surgery. Proximal anastomosis was initially attempted to the ascending aorta. However, the ascending aorta was thin and weak, we decided to anastomose to the side of the aortic arch. Proximal anastomosis was performed with an anastomotic device. Postoperative coronary computed tomography (CT) showed that the graft was patent.

We report a case of ureteral endometriosis thought to have developed following relapse of pelvic peritoneal endometriosis after laparoscopic surgery. The patient was a woman in her late 40s who had undergone laparoscopic right adnexectomy for an endometrial cyst 5 years earlier. Electrocoagulation was performed for residual endometriosis of adherent cyst wall on the right sacrouterine ligament. The normal left ovary was preserved and she received no postoperative hormonal therapy. She developed right back pain during menstruation 5 years after the surgery. Pyeloureterography revealed stenosis of the ureter to the right of the uterus. Urinary cytology revealed endometrial cells with no atypia. Conservative management was opted for because malignant transformation of endometriosis was considered unlikely and she was expected to reach menopause within a few years. She is now doing well 24 months after initiation of progestin treatment with placement of a ureteral stent. Postoperative hormonal therapy is recommended for patients who are considered to have possible lesions of residual endometriosis and for whom ovarian function is preserved.
