Thirty-year clinical experience in gamma knife radiosurgery for trigeminal schwannomas.

We aimed to evaluate the radiographic and clinical outcomes after gamma knife radiosurgery (GKRS) for trigeminal schwannomas (TSs). A total of 87 patients who underwent GKRS for TSs between 1990 and 2020 were enrolled. The mean tumor volume was 4.

Predictive factors for high-grade transformation in benign meningiomas.

Objective: Although they are generally slow-growing benign tumors, meningiomas may recur after surgery with transformation into atypical meningiomas. The purpose of this study was to investigate the radiological and histopathological factors that predict the risk of tumor progression from a benign to an atypical meningioma.

Patients And Methods: All patients treated for recurrent meningiomas in whom the tumor showed histopathologically confirmed high-grade transformation (HGT) from a benign to an atypical meningioma between 2001 and 2017 were included.

Growth rate and fate of untreated hemangioblastomas: clinical assessment of the experience of a single institution.

Background: The growth rate and natural history of untreated hemangioblastomas remain unclear. This study investigated the natural history of untreated intracranial hemangioblastomas and predictors of tumor growth using volumetric assessment.

Method: This study retrospectively enrolled 31 patients with untreated hemangioblastomas between 2004 and 2017 who were followed up for at least 12 months.

Comparison of Surgical Results between Soft Ruptured Disc and Foraminal Stenosis Patients in Posterior Cervical Laminoforaminotomy.

Objective: Posterior cervical laminoforaminotomy is used to relieve cervical nerve root compression caused by a laterally herniated soft cervical disc or spondylotic spur and its several advantages and disadvantages compared with anterior cervical discectomy were reported. We compared surgical results between soft ruptured disc and foraminal stenosis in posterior cervical laminoforaminotomy.

Methods: We performed a retrospective review of 47 patients performed single level posterior cervical laminoforaminotomy for cervical radiculopathy between 2004 and 2012.

Two pregnancy cases of uterine scar dehiscence after laparoscopic myomectomy.

Uterine scar dehiscence following laparoscopic myomectomy rarely occurs but can compromise both maternal and fetal well-being in subsequent pregnancy. We here present two cases of pregnancy complicated by preterm birth that resulted from uterine scar dehiscence following laparoscopic myomectomy. First case was a nulligravida who had scar dehiscence at 26 weeks of gestation after having a laparoscopic myomectomy 3 months prior to conception.
