While parenchymal metastases are common in solid systemic cancers, subependymal metastases are rare. Approximately half of the reported cases of intraventricular metastases originate from renal carcinoma. A 65-year-old man presented with general fatigue, appetite loss, nausea, and disorientation. Radiological examination revealed diffuse periventricular tumors. The patient underwent an open biopsy via right frontotemporal craniotomy. The patient was diagnosed with metastatic small cell lung carcinoma after histopathological examination...

The outcome of severe acute subdural hematoma is unfavorable. In particular, patients with levels of consciousness of Glasgow Coma Scale(GCS)3 or 4 tend to be refractory to treatment. Decompressive craniotomy should be promptly performed to remove hematoma. However, if an operating room is not immediately available, emergency burr hole surgery is sometimes performed in the emergency room(primary care room)prior to craniotomy. A previous study has reported that the interval from injury to surgery influences the outcome of severe acute subdural hematoma...

A girl aged 3 months presented with multiple seizures within 12 hours and was noted to have a palpable swelling over the right temporal region. MRI of the brain revealed a large right frontotemporal tumour, suggestive of supratentorial primitive neuroectodermal tumour. She underwent a stealth-guided craniotomy and debulking of the tumour. Histopathology and immunochemistry of the specimen, however, indicated a high-grade tumour with glioblastoma and neuroblastic components. She underwent adjuvant chemotherapy following the surgery and is well at 7-month follow-up...

BACKGROUND: Anterior cranial fossa dural arterio-venous fistulas (DAVFs) represent 6% of all intracranial DAVFs; characteristically they show an aggressive behaviour with high risk of intracranial haemorrhage. Peculiar anatomical features, such as feeding by the ethmoidal arteries and the pattern of venous drainage (frequently with varices that mimic aneurysmal dilatation), can be evaluated in detail only by digital subtraction angiography (DSA), which represents the "gold standard" in the diagnosis of such cranial fistulas...

A healthy 26-year-old man with cerebral arteriovenous malformation underwent staged endovascular embolization with Onyx followed by awake craniotomy for resection. The perioperative course was complicated by tachycardia and severe intraoperative hypoxemia requiring significant oxygen supplementation. Postoperative chest computed tomography (CT) revealed hyperattenuating Onyx embolization material within the pulmonary vasculature, and an electrocardiogram indicated possible right heart strain, supporting clinically significant embolism...

In common with other stereotactic procedures, stereotactic laser thermocoagulation (SLT) promises gentle destruction of pathological tissue, which might become especially relevant for epilepsy surgery in the future. Compared to standard resection, no large craniotomy is necessary, cortical damage during access to deep-seated lesions can be avoided and interventions close to eloquent brain areas become possible. We describe the history and rationale of laser neurosurgery as well as the two available SLT systems (Visualase® and NeuroBlate®; CE marks pending)...

OBJECTIVE Gamma Knife surgery (GKS) is a promising treatment modality for patients with vestibular schwannomas (VSs), but a small percentage of patients have persistent postradiosurgical tumor growth. The aim of this study was to determine the clinical and quantitative MRI features of VS as predictors of long-term tumor control after GKS. METHODS The authors performed a retrospective study of all patients with VS treated with GKS using the Leksell Gamma Knife Unit between 2005 and 2013 at their institution...

OBJECTIVES: The most painful stages of craniotomy are the placement of the pin head holder and the skin incision. The primary aim of the present study is to compare the effects of the scalp block and the local anesthetic infiltration with bupivacaine 0.5% on the hemodynamic response during the pin head holder application and the skin incision in infratentorial craniotomies. The secondary aims are the effects on pain scores and morphine consumption during the postoperative 24h. METHODS: This prospective, randomized and placebo controlled study included forty seven patients (ASA I, II and III)...

BACKGROUND: Postoperative infection after craniotomy carries an increased risk of morbidity and mortality. Identification and correction of the risk factors should be prioritized. The association of intraoperative hyperglycemia with postoperative infections in patients undergoing craniotomy is inadequately studied. METHODS: A total of 224 patients were prospectively enrolled in 2 major medical centers to assess whether severe intraoperative hyperglycemia (SIH, blood glucose ≥180 mg/dL) is associated with an increased risk of postoperative infection in patients undergoing craniotomy...

Awake craniotomy (AC), defined as the performance of at least part of an open cranial procedure with the patient awake, has been tied to beneficial outcomes compared with similar surgery under general anesthesia. Improved anesthetic techniques have made a major contribution to the increasing popularity of AC. However, the heterogeneity of practice among institutions doing large numbers of ACs raises questions (often among those who only occasionally perform AC - i.e., practitioners in low-volume AC institutions) as to the ideal anesthetic technique for AC...

BACKGROUND: Brain abscess is an uncommon but life-threatening infection. It involves a focal, intracerebral infection that begins in a localized area of cerebritis and develops into a collection of pus, surrounded by a well-vascularized capsule. Brain abscess still poses a significant problem in developing countries but rarely in developed countries. Predisposing factors vary in different parts of the world. With the introduction of antibiotics and imaging studies, the mortality rate has decreased between 5% and 15%...

Farm workers are at increased risk for animal-inflicted head injuries that are associated with significant morbidity and occasionally may be fatal. These injuries may cause permanent eye damage with or without concomitant skull base fracture. Here, we present a male farmer who suffered a cow attack that resulted in perforating orbital injury with comminuted frontobasal cranial fracture caused by a cow's horn. The next day, the patient developed nasal and orbital cerebrospinal fluid (CSF) leak. Computed Tomography cisternography revealed CSF leakage to frontal and maxillary sinuses...

The rarity of hemangiopericytoma (HPC) and its controversial histological classification result in its frequent misdiagnosis and thus make the treatment quite challenging. It is often difficult to distinguish these tumors from meningiomas based on clinical features and radiological findings. This is a case report of a man, diagnosed clinically and radiologically as meningioma, which turned out to be anaplastic HPC on histological examination. A 30-year-old man presented with 3 months of progressively worsening of headache and blurring of vision...

INTRODUCTION: Awake craniotomy for brain tumor resection is usually well-tolerated and most of the patients are satisfied. However, in studies reporting the patients' postoperative perception of the awake craniotomy procedure, about half of them have experienced some degree of intraoperative pain. Pain was mild (intensity between 1 and 2 on the visual analogical score) short lasting in most cases, and did not challenge the procedure. Pain was reported as moderate in about 25% and exceptionally severe...

INTRODUCTION: The aim of brain glioma surgery is to maximize the quality of resection, while minimizing the risk of sequelae. Due to the frequent location of gliomas near or within eloquent areas, owing to their infiltrative feature, and because of major interindividual variability, the anatomofunctional organization and connectivity must be studied individually. Therefore, to optimize the benefit-to-risk ratio of surgery, intraoperative functional mapping is extensively used. MATERIAL AND METHODS: This article aims at describing the rationale, indications and practical aspects of intraoperative direct electrical bipolar electrostimulation for cortical and subcortical mapping under awake conditions using the asleep-awake asleep anaesthetic protocol in the setting of cerebral gliomas...
