Background Giant cell tumors (GCTs) are rare osseous tumors that rarely appear in the skull. Methods We review the clinical course of a 28-year-old previously healthy woman with a complicated GCT. Results The reviewed patient presented with a middle cranial fossa tumor acutely complicated by reactive mastoiditis. Left tympanomastoidectomy was performed for drainage of the mastoiditis and for biopsies of the tumor. Due to the challenging tumor location, the patient was treated with denosumab, a fully humanized monoclonal antibody against receptor activator of nuclear factor kappa-B ligand, for 7 months, which resulted in significant preoperative tumor shrinkage...

BACKGROUND: Despite recent advances in the medical and surgical fields, complications such as infection, pneumonia, or brain swelling may occur after a craniotomy. In some patients, perioperative antibiotic prophylaxis causes adverse effects such as itching, rash, or digestive conditions. Certain patients still develop infections severe enough to require a repeat operation despite antibiotic prophylaxis. Acupuncture has been used to treat inflammatory conditions, and many basic and clinical studies have provided evidence of its anti-inflammatory and immune regulatory effects...

BACKGROUND: Peripheral nerve injury causes physiological changes in primary afferent neurons. Neuropathic pain associated with peripheral nerve injuries may reflect changes in the excitability of the nervous system, including the spinothalamic tract. Current alternative medical research indicates that acupuncture stimulation has analgesic effects in various pain symptoms. However, activation changes in the somatosensory cortex of the brain by acupuncture stimulation remain poorly understood...

Brain abscess commonly occurs secondary to an adjacent infection (mostly in the middle ear or paranasal sinuses) or due to hematogenous spread from a distant infection or trauma. Pulmonary arteriovenous fistulas (AVFs) are abnormal direct communications between the pulmonary artery and vein. We present two cases of brain abscess associated with asymptomatic pulmonary AVF. A 65-year-old woman was admitted with a headache and cognitive impairment that aggravated 10 days prior. An magnetic resonance (MR) imaging revealed a brain abscess with severe edema in the right frontal lobe...

Focal cerebral ischemia (i.e., ischemic stroke) may cause major brain injury, leading to a severe loss of neuronal function and consequently to a host of motor and cognitive disabilities. Its high prevalence poses a serious health burden, as stroke is among the principal causes of long-term disability and death worldwide(1). Recovery of neuronal function is, in most cases, only partial. So far, treatment options are very limited, in particular due to the narrow time window for thrombolysis(2,3). Determining methods to accelerate recovery from stroke remains a prime medical goal; however, this has been hampered by insufficient mechanistic insights into the recovery process...

OBJECTIVE The aim of the present study was to evaluate the usefulness of navigated transcranial magnetic stimulation (nTMS) as a prognostic predictor for upper-extremity motor functional recovery from postsurgical neurological deficits. METHODS Preoperative and postoperative nTMS studies were prospectively applied in 14 patients (mean age 39 ± 12 years) who had intraparenchymal brain neoplasms located within or adjacent to the motor eloquent area in the cerebral hemisphere. Mapping by nTMS was done 3 times, i...

OBJECTIVE Fragmentation of care has been recognized as a major contributor to 30-day readmissions after surgical procedures. The authors investigated the association of evaluation in the hospital where the original procedure was performed with the rate of 30-day readmissions for patients presenting to the emergency department (ED) after craniotomy for primary brain tumor resection. METHODS A cohort study was conducted, involving patients who were evaluated in the ED within 30 days after discharge following a craniotomy for primary brain tumor resection between 2009 and 2013, and who were registered in the Statewide Planning and Research Cooperative System (SPARCS) database of New York State...

OBJECTIVE Maximum extent of resection (EOR) for lower-grade and high-grade gliomas can increase survival rates of patients. However, these infiltrative gliomas are often observed near or within eloquent regions of the brain. Awake surgery is of known benefit for the treatment of gliomas associated with eloquent regions in that brain function can be preserved. On the other hand, intraoperative MRI (iMRI) has been successfully used to maximize the resection of tumors, which can detect small amounts of residual tumors...

INTRODUCTION: Adequate functioning of the blood-brain barrier (BBB) is important for brain homoeostasis and normal neuronal function. Disruption of the BBB has been described in several neurological diseases. Recent reports suggest that an increased permeability of the BBB also contributes to increased seizure susceptibility in patients with epilepsy. The endothelial glycocalyx is coating the luminal side of the endothelium and can be considered as the first barrier of the BBB. We hypothesise that an altered glycocalyx thickness plays a role in the aetiology of temporal lobe epilepsy (TLE), the most common type of epilepsy...

Intracranial aspergillosis (ICA) is very rare in the immunocompetent individuals, usually misdiagnosed as a tumor or an abscess. A high index of clinical suspicion is required in patients who present with focal neurological deficits, headache, or seizures. We report the case of a 25-year-old immunocompetent female, who presented with a 15-month history of headache, seizures, left-sided proptosis and ophthalmoplegia, and right hemiparesis. Recovery from the symptoms and decrease in the lesion size seen on the radiological assessment were achieved through two decompressive craniotomies followed by prolonged combined systemic antifungal therapies...

Chronic subdural hematoma (cSDH) is a common condition, the frequency of which further increases due to an aging population and more frequent use of antithrombotic drugs. It leads to unspecific symptoms and neurological deficits and is usually treated surgically. Burr hole trepanation and twist drill craniostomy have become the therapeutic standards with craniotomy being rarely used for recurrent cases. Although recurrences are relatively common, in most cases a good outcome can be achieved even in the elderly; however, as cSDH is associated with other comorbidities, it is indicative of an increased morbidity and mortality...

BACKGROUND: The middle meningeal artery (MMA) is well known to function as an important collateral channel to the territory of the anterior cerebral artery in moyamoya disease. This study was aimed to evaluate whether indocyanine green (ICG) videoangiography could visualize the anterior branch of the MMA before craniotomy during surgical revascularization for moyamoya disease. METHODS: This study included 19 patients who developed TIA, ischemic stroke or hemorrhagic stroke due to moyamoya disease...

PURPOSE: This work aims to determine dose variability via a brain metastases resection cavity shrinkage model (RC-SM) with I-125 or Cs-131 LDR seed implantations. METHODS: The RC-SM was developed to represent sequential volume changes of 95 consecutive brain metastases patients. All patients underwent serial surveillance MR and change in cavity volume was recorded for each patient. For the initial resection cavity, a prolate-ellipsoid cavity model was suggested and applied volume shrinkage rates to correspond to 1...

BACKGROUND: Thalamic dysfunction has been implicated in overall chronic neurological dysfunction after traumatic brain injury (TBI), however little is known about the underlying histopathology. In experimental diffuse TBI (dTBI), we hypothesize that persisting histopathological changes in the ventral posteromedial (VPM) nucleus of the thalamus is indicative of progressive circuit reorganization. Since circuit reorganization in the VPM impacts the whisker sensory system, the histopathology could explain the development of hypersensitivity to whisker stimulation by 28days post-injury; similar to light and sound hypersensitivity in human TBI survivors...

BACKGROUND: Despite selection process before awake-craniotomy, some patients experience an unexpected decline in language functions in the operating-room (OR), compared to their baseline evaluation, which may impair their functional monitoring. To investigate this phenomenon we prospectively compared language function day-before surgery and upon entrance to the OR. METHODS: Data was prospectively collected from consecutive patients undergoing awake-craniotomy with intra-operative cortical mapping for resection of gliomas affecting language areas...
