Objective In this study, we investigate our institutional experience of patients who underwent endoscopic endonasal transsphenoidal approach for treatment large and giant pituitary adenomas emphasizing the surgical results approach-related complications. Method The authors reviewed 28 consecutive surgery between March, 2010 2014. Results mean preoperative tumor diameter was 4.6 cm. Gross-total resection achieved in 14.3%, near-total 10.7%, subtotal 39.3%, partial 35.7%. Nine experienced...

This study was conducted to investigate the success rate of using facial motor evoked potential (FMEP) orbicularis oculi and oris muscles for nerve function monitoring with use a stepwise protocol, its usefulness in predicting outcome during cerebellopontine angle (CPA) surgeries.FMEPs were recorded intraoperatively from 60 patients undergoing CPA surgeries. Transcranial electrocortical stimulation (TES) performed corkscrew electrodes positioned at hemispheric montage (C3/C4 CZ). The...

<b>Background and Objective</b> Supplementary motor area (SMA) syndrome, an executive disorder with speech dysfunctions, is rather unpredictable typically a complete or almost functional recovery within weeks months. Compensatory mechanisms are associated contralateral cortical recruitment of the lateral premotor circuitry. We sought to investigate role healthy SMA for following surgery in medial frontal lobe. <b>Methods</b> A 48-year-old right-handed man presented focal seizures. The...

While the pathophysiology of space-occupying lesions inside tarsal tunnel causing syndrome (TTS) is obvious, occurrence a posterior tibial nerve (PTN) mass outside but mimicking or in combination with TTS symptomatology less clear. Therefore, we report three rare cases patients presenting symptoms combined distal leg PTN schwannoma, all whom were treated tumor resection and decompression. All had long-lasting history ankle pain radiating to medial aspect foot toes. Pain was especially...

The ventriculus terminalis is a small cavity inside the conus medullaris that formed during embryonic development. Previous reports regarding cystic lesion of (CLVT) in adults have detailed broad and diversified distribution terms clinical symptoms, evolution, neurological findings, treatment. Therefore, nonstandardized management has led to unsatisfactory outcomes. Thus, authors propose new classification system which presentation taken into account standardize cases facilitate proper these...

ABSTRACT Objective In this study, we review the institution’s experience in treating malignant peripheral nerve sheath tumors (MPNSTs). A secondary aim was to compare outcomes between MPNSTs with and without neurofibromatosis type 1 (NF1). Methods Ninety-two patients MPNSTs, over a period of 20 years, were reviewed. retrospective chart performed. The median age 43.5 years (range, 3–84 years) 55.4% female; 41 (44.6%) had NF1-associated tumors. Results Mean tumor sizes 15.8 ± 8.2 cm 10.8 6.3...

The principle of patient autonomy is a cornerstone bioethics. According to this concept, patients should be given the power make decisions related their treatment. It an important component modern medical ethics, which has received much interest in current literature. However, rate participation and willingness participate are variable according cultural, social family environments they inserted. aim paper promote brief descriptive review on autonomy, preferences use informed consent as...

The insertion of a ventriculoperitoneal shunt (VPS) is considered the standard care for several forms hydrocephalus. Abdominal complications are most common with this procedure, comprising up to 30% all shunt-related problems. Conversely, visceral perforation or extrusion apparatus rare. Herein we report rare complication VPS in which peritoneal catheter was spontaneously extruded through urethra patient neobladder. We further discuss pathogenesis, diagnosis, and treatment condition.

Background The occurrence of trigeminocardiac reflex (TCR) is known to be a negative prognostic factor for hearing preservation in cerebellopontine angle tumor surgery. Our study was conducted investigate brainstem auditory evoked potential (BAEP) changes after this surgery and evaluate their impact on postoperative function. Methods Five 102 consecutive patients had an intraoperative TCR (4.9%) were retrospectively evaluated the BAEP function (7 10 d surgery). One 5 preoperatively deaf...

Endoscopic third ventriculostomy (ETV) has been established as an effective method in the treatment of tumoral obstructive hydrocephalus. Delayed closure ETV stoma attributed to scarring involving ventricular floor. Secondary obstruction due intraventricular tumor seeding is extremely rare condition, with only one case described date. The authors report on a unique late caused by metastatic recurrent medulloblastoma 9 years after initial treatment. patient was submitted second endoscopic...

Traumatic posterior fossa epidural hematomas are uncommon lesions. Among these lesions, retroclival (REDH) particularly rare conditions that usually occur in the pediatric population due to predisposing anatomical features this patient group. We describe a typical case of traumatic REDH from mechanism trauma outcome. This 8-year-old girl was involved motor vehicle accident leading whiplash cervical injury and cranial nerve palsy. Any children severe with such sequence events should raise...
