Surgery after administering bevacizumab should be carefully considered particularly because of wound healing concerns. A 27-year-old man presented with multiple tumor recurrences after gross total removal of a left temporal oligodendroglioma (1p/19q-noncodeleted). Whole brain radiotherapy with concomitant temozolomide and bevacizumab was immediately prescribed; however, the patient's condition deteriorated because of brain herniation. Three days after administering bevacizumab, an emergency tumor removal with external decompression and a ventriculo-peritoneal shunt was performed...

BACKGROUND: Vertex epidural hematoma (VEH) is an uncommon presentation of extra-axial hematomas. It can represent a surgical dilemma regarding when and how to operate, particularly considering the potential implication of the superior sagittal sinus (SSS). OBJECTIVE: Here, we illustrate the surgical technique for VEH as well as review of the existing literature. METHODS: A 60-year-old male sustained a ground level fall resulting in complete diastasis of the sagittal suture with underlying large VEH causing significant mass effect on the SSS and bi-hemispheric convexities...

INTRODUCTION: Awake craniotomy allows continuous monitoring of patients' neurological functions during open surgery. Anesthesiologists have to sedate patients in a way so that they are compliant throughout the whole surgical procedure, nevertheless maintaining adequate analgesia and anxiolysis. Currently, the use of α2-receptor agonist dexmedetomidine as the primary hypnotic-sedative medication is increasing. METHODS: Nine patients undergoing awake craniotomy were treated with refined monitored anesthesia care (MAC) protocol consisting of a combination of local anesthesia without scalp block, low-dose infusion of dexmedetomidine, propofol, and remifentanil, without the need of airways management...

We compared the surgical efficacy of the supraorbital key-hole approach (SKA) to conventional unilateral frontotemporal craniotomy (UFTC) for the treatment of patients with unilateral-dominant bilateral frontal contusions (BFCs). A retrospective analysis of 62 patients with unilateral-dominant BFCs who underwent surgery at our institute between 2014 and 2017 was performed. There were 26 patients who underwent SKA (group A) and 36 who underwent UFTC (group B). Postoperative computed tomography scans showed satisfactory evacuation of the frontal cerebral contusions in both groups (p > 0...

Of all brain metastases, the most common primary lesion is derived from the lung. These types of metastases enlarge aggressively with unfavorable prognoses. We report the case of a 75-year-old male patient who had a history of pulmonary resection for Stage IA non-small cell lung cancer(NSCLC), and received chemotherapy. One year after NSCLC surgery, he experienced a cardiogenic cerebral infarction, and anticoagulant therapy was initiated. Mass lesions with hemorrhage were detected bilaterally in the frontal lobes through magnetic resonance imaging three years after the NSCLC surgery...

Metastatic tumors are the most common mass lesions in the brain. This case reports a rare form of sarcoma with metastasis to the brain. The appropriate management of a patient with metastatic alveolar soft part sarcoma to the brain is discussed. Author describes a 32-year-old gentleman diagnosed with primary tumor at gluteus and distant metastases at lower lobe of right lung and the brain. Histopathology proves diagnosis as alveolar soft part sarcoma. Craniotomy with excision of brain lesion was done. Repeated magnetic resonance imaging of the brain after 2 months showed rapidly growing new lesions...

We report an eight years female child of symptomatic giant Rathke's cleft cyst extending from right parasellar, paraventricular region to right fronto-temporo-parietal cortical surface which is an unusual site for Rathke's cyst. MRI Brain scans of patient who presented with diminution of vision in right eye with headache and vomiting revealed a large cystic mass in right parasellar, paraventricular region with peripheral enhancement and midline shift. In this case, we performed the right fronto-temporo-parietal craniotomy with drainage and marsupilization of cyst wall...

REVIEW
Christian Hoppe, Juri-Alexander Witt, Christoph Helmstaedter, Thomas Gasser, Hartmut Vatter, Christian E Elger
Besides other innovative stereotactic procedures (radiofrequency thermocoagulation, focused ultrasound, gamma knife) laser interstitial thermotherapy (LiTT) provides minimally invasive destruction of pathological soft tissues which could be especially relevant for epilepsy surgeries involving adult and pediatric patients. Unlike standard resections, no craniotomy is required; just a tiny borehole trepanation is sufficient. Damage to cortical areas when accessing deep lesions can be minimized or completely avoided, and treating epileptogenic foci near eloquent or even vital brain areas becomes possible...

INTRODUCTION: We performed a cost-minimization study comparing the supraorbital and endoscopic, endonasal (EEA) approaches with or without the addition of craniotomy for the resection of olfactory groove meningioma. METHODS: We built a decision tree using probabilities of gross total resection and CSF leak rates with the supraorbital approach versus EEA with and without additional craniotomy. The cost (not charge or reimbursement) at each 'stem' of this decision tree, for both surgical options was obtained from our hospital's finance department...

BACKGROUND  : Radiosurgery is being increasingly used post craniotomy for brain metastasis, instead of whole-brain radiation. We report a case of scalp metastasis following craniotomy and radiosurgery, along with a systematic review of the literature. METHODS        : Our patient was a 70-year-old male who presented with a scalp metastasis, two years after craniotomy and radiosurgery, for a solitary brain metastasis from esophageal carcinoma. Using Medline® (United States National Library of Medicine, Bethesda, MD), we performed a systematic review of the literature to identify cases of isolated scalp metastases following craniotomy for brain lesions...

Lack of scientific reproducibility is a growing concern and weak experimental practices may contribute to irreproducibility. Here, we describe an optimized and versatile protocol for stereotaxic intrahippocampal administration of Kainic Acid (KA) in mice with a C57Bl6 background. In this protocol, KA administration is combined with in vivo recording of neuronal activity with wired and wireless setups. Following our protocol, KA administration results in a robust dose-dependent induction of low-level epileptiform activity or Status Epilepticus (SE) and induces previously characterized hallmarks of seizure-associated pathology...

Xiaopeng Guo, Junji Wei, Lu Gao, Bing Xing, Zhiqin Xu
RATIONALE: Postoperative coma is not uncommon in patients after craniotomy. It generally presents as mental state changes and is usually caused by intracranial hematoma, brain edema, or swelling. Hyperammonemia can also result in postoperative coma; however, it is rarely recognized as a potential cause in coma patients. Hyperammonemic coma is determined through a complicated differential diagnosis, and although it can also be induced as a side effect of valproate (VPA), this cause is frequently unrecognized or confused with upper gastrointestinal hemorrhage (UGH)-induced hepatic encephalopathy...

BACKGROUND: There is a significant increase and large variation in craniotomy costs. However, the causes of cost differences in craniotomies remain poorly understood. OBJECTIVE: To examine the patient and hospital factors that underlie the cost variation in tumor craniotomies using 2 national databases: the National Inpatient Sample (NIS) and Vizient, Inc. (Irving, Texas). METHODS: For 41 483 patients who underwent primary surgery for supratentorial brain tumors from 2001 to 2013 in the NIS, we created univariate and multivariate models to evaluate the effect of several patient factors and hospital factors on total hospital cost...
