Methods Eighty cases of supratentorial tumor resection were randomly divided into a group A and a group S, 40 cases in each group. All the patients were anesthetized with 2% Sevoflurane. The patients in group A received eleetroacupuneture at Hegu （合谷 LI 4） and Waiguan （外关 TE 5）, Jinmen （金门 BL 63） and Taichong （太冲 LR 3）, Zusanli （足三里 ST 36） and Qiuxtu（丘墟 GB 40） from anesthesia beginning to the end of operation, and in group S without electroacupuncture. tidal Sevoflurane concentration, minimum alveolar concentration （MAC）, bispectral index （BIS） and the information during anesthesia recovery stage were recorded, respectively. Results The end-tidal concentration and MAC of Sevoflurane in group A at all times were significant lower than those in group S （P〈0.05, P〈0.01） with a Sevoflurane saving of 9.62% on average. The BIS in group A during a few phases were higher than that in group S （all P〈0.05）. During anesthesia recovery stage, the time of each phase in group A was significantly shorter than that in group S （all P〈0.01）. No dysphoria and one case with nausea and vomiting were shown in group A, but in group S, 2 patients had dysphoria and 3 patients had nausea and vomiting. Conclusion Electroacupuncture combined with Sevoflurane anesthesia can decrease the dosage of Sevoflurane, shorten the recovery time of anesthesia and improve the quality of anesthesia recovery of the patients undergoing resection of supratentorial tumor.展开更多

It is a rare tumor in the central nervous system, with an even rarer occurrence during adulthood. It may develop at an atypical and uncommon site, such as the cerebellopontine angle （CPA）, and such tumors rarely present with supratentorial extension. The present study reports an adult case of medulloblastoma in the CPA extending to the supratentorial area. The patient presented with complaints of headache, vertigo, hearing difficulty in the left ear, nausea/vomiting, and unsteady gait. Disequilibrium began 4 weeks earlier. Examination revealed normal cranial nerves, and computed tomography showed a hyperdense lesion, with a heterogeneously enhancing mass, in the left CPA region. The patient underwent a nearly total excision of the lesion in the CPA region. Histopathological examination confirmed medulloblastoma, WHO grade IV. Postoperatively, the patient received radiotherapy and remained asymptomatic for 30 months. However, he received two more surgeries for relapse and progression of medulloblastoma and eventually died. A CPA medulloblastoma with supratentorial extension is relatively rare in the clinic.展开更多

The aim of this study was to investigate whether the presence of SAE among acute SICH with coma would predict a poor outcome. Methods: A retrospective of consecutive patients was selected for study. All registered an adult intensive care unit (ICU) of university teaching hospital between June, 2013 and July, 2015. Brain computed tomography (CT) scans were analyzed on admission and at coma onset or after coma onset. Univariate and Cox regression analyses were performed. Results: A total of 379 SICH with coma was studied. Among these, 245 (64.6%) SICH patients with coma due to SAE and 134 (35.4%) SICH with coma no SAE was compared. Our data showed that the frequency of the SAE in SICH patients increased at about double the proportion over the four SIRS criteria. The SICH patients with SAE were more likely to present with infection (100% vs 35.8%) and multiple organ failure (1.2 ± 0.9 vs 0.1 ± 0.3), especially nosocomal brain failure (60.4%). The 30 days mortality was significantly higher in the SAE group than those who did not (60.8% vs 11.2%). In Cox multivariate logistic analysis, the SAE (RR, 4.4;95% CI, 2.296 - 8.422;P = 0.000) was more likely to related to risk on death in SICH patient with coma. Conclusions: SAE is a frequent complication of SICH, which greatly increased risk of death among SICH patients with coma.展开更多

We report the case of a 78-year-old Philipino female who was found to have a large right fronto-parietal mass after a minor fall. She had a small amount of hemorrhage within the cyst but was stable for discharge the following day. She was readmitted 5 days later with acute onset severe headache and leftside weakness. On repeat imaging, her cyst had grown in size and had large acute hemorrhage within it. She was taken to the operating room for craniotomy and cyst resection. She recovered well post-operatively. This is the first known case of a giant supratentorial enterogenous cyst presenting with symptomatic enlargement due to large hemorrhage within the cyst. Enterogenous cysts should be considered on the differential diagnosis of hemorrhagic supratentorial giant cysts.展开更多

Only 50 cases are reported in the literature including pediatric and adult patients. We report a 30-year-old male with sensory-type seizures who was found to have a right posterior frontal cortical lesion with large cystic component. The lesion was resected completely and histopathology and immunohistochemistry examinations confirmed anaplastic ependymoma WHO grade III. The patient received radiotherapy treatment post-surgery, and he was tumor free one year after treatment.展开更多
