Intracranial metastasis of prostate cancer is rarely seen, and there are few studies in this regard in the literature. Most of these studies in the literature comprise the metastasis of prostate cancer to the sphenoid sinus, and metastasis to the frontal and ethmoid sinus is a much rare entity. Association of visual symptoms, epistaxis, headache, and hematuria may indicate a urologic malignancy in terms of the origin of the primary tumor. This study was aimed to present the prostate cancer case of a 73-year-old patient whose paranasal sinus tomograms revealed the presence of frontal and ethmoid sinus metastasis...

BACKGROUND: Pituitary carcinoma (PC) is a rare type of malignant intracranial neoplasm defined as distant metastasis of pituitary adenoma (PA). Although PC incidence is low because only 0.1% to 0.2% of PAs ultimately develop into PCs, the prognosis is poor and 66% of patients die within the first year. Existing therapeutic measures, including surgical removal, chemotherapy, and radiotherapy, have limited effectiveness. The lack of efficacy of current treatments is largely caused by the limited understanding of the molecular pathogenesis of PA and the malignant transformation to PC...

Seizures have considerable impact on a patient's quality of life. While guidelines have been articulated to direct clinicians in their management of patients with IMD who suffer from seizure, there have been few attempts to identify the seizure rate in IMD and to determine which primary cancers may be associated with an increased seizure incidence. To determine the incidence of seizure in patients with IMD. A systematic review on seizure incidence in patients with IMD from the magnetic resonance imaging (MRI) era was performed...

Intracranial hemangiopericytoma (HPC) is a rare brain tumor with aggressive biologic behavior associated with high recurrence rate and often with extracranial metastasis. The most common sites of extracranial metastasis of the intracranial HPC are the long bones, lung, liver and abdominal cavity in the order of frequencies. Extracranial metastases usually occur long after the initial diagnosis of the primary tumor. Metastatic intracranial HPC to the vertebra has been rarely reported. We present a case of intracranial HPC metastasized to the L2 vertebral body 13 years after multiple surgical resections and radiotherapy of the primary intracranial HPC...

OBJECTIVE: Elevated cell counts and protein levels in cerebrospinal fluid (CSF) result from disease activity in patients with leptomeningeal carcinomatosis (LMC). Previous studies evaluated the use of CSF profiles to monitor a treatment response or predict prognosis. CSF profiles vary, however, according to the sampling site and the patient's systemic condition. We compared lumbar and ventricular CSF profiles collected before intraventricular chemotherapy for LMC and evaluated the association of these profiles with patients' systemic factors and LMC disease activity...

Bone scintigraphy (BS) is a well--established commonly used imaging modality for staging and follow--up evaluation of cancer patients. Occasionally, BS may show asymptomatic unusual extraosseous lesions in the body which may or may not be related to primary disease. We here present an interesting case of carcinoma cervix in whom (18)F sodium fluoride positron emission tomography-computerized tomography (PET-CT) bone scan detected an intracranial lesion. Initially, this lesion was suspected as brain metastasis; however, later on, combined PET--CT images and contrast-enhanced CT confirmed this lesion as calcified falcine meningioma in the right posterior parietal region...

Melanoma is the malignancy with the highest rate of dissemination to the central nervous system once it metastasizes. Until recently, the prognosis of patients with melanoma brain metastases (MBM) was poor. In recent years, however, the prognosis has improved due to high-resolution imaging that facilitates early detection of small asymptomatic brain metastases and early intervention with local modalities such as stereotactic radiosurgery. More recently, a number of systemic therapies have been approved by the Food and Drug Administration for metastatic melanoma, resulting in improved survival for many MBM patients...

The authors present the history of two patients. The first patient, a 69-year-old woman was diagnosed with locally invasive triple negative breast cancer with pulmonary and cerebral metastases. Complete radiological remission of the clinically asymptomatic cerebral metastases was detected under systemic chemotherapy with carboplatin-docetaxel (75 mg/m(2)). Later, the patient received whole brain radiotherapy and a second line of chemotherapy. The overall survival was 20 months from the diagnosis of cerebral metastases with conservation of partial autonomy...

BACKGROUND AND PURPOSE: While standard guidelines assist in target delineation for head and neck radiation therapy planning, the complex anatomy, varying patterns of spread, unusual or advanced presentations, and high risk of treatment-related toxicities produce continuous interpretive challenges. In 2007, we instituted weekly treatment planning quality assurance rounds as a joint enterprise of head and neck radiation oncology and neuroradiology. Here we describe its impact on head and neck radiation therapy target delineation...

Intracranial hemangiopericytomas (HPC) are rare vascular tumors. They account for 0.4% of primary central nervous system tumors. HPC is more commonly located supratentorially and tends to occur in a younger age group, with average age at presentation of 38-42 years. The tumor was found throughout the entire CNS, usually superficially and closely related to the meninges. Moreover, they have a strong tendency for local recurrence and extracranial metastasis. Given the clinical, pathological and imaging similarities between Hemangiopericytoma and angioblastic/anaplastic meningioma and the necessity of differentiating these two (choosing the proper treatment and prognosis), we present a report of meningeal Hemangiopericytoma tumor in a 33-year-old female...

Residual or recurrent hemangiopericytoma (HPC) has been treated with radiosurgery; however, its long-term outcome is not well known. This study is to investigate the long-term outcome of gamma knife radiosurgery (GKS) for residual or recurrent HPCs. We conducted a retrospective analysis of 18 patients who underwent gamma knife radiosurgery for residual or recurrent HPCs. Of the 18 patients, 10 patients had high-grade HPCs (27 tumors) and 8 had low-grade HPCs (13 tumors). Median overall survival (OS) after the first GKS was 134...

The basement membrane collagen IV-degrading matrix metalloproteinases -2 and -9 (MMPs) are most often linked to the malignant phenotype of tumor cells by playing a critical role in invasion, metastasis, angiogenesis, and vasculogenesis. We verified the activity of these two MMPs in the sera of patients affected by brain tumors (20 gliomas, 28 meningiomas and 20 metastasis) by zymography. The sera of 25 healthy volunteers with no concomitant illnesses were used for controls. Zymography showed four dominant gelatinolytic bands of 240, 130, 92 (MMP-9) and 72 (MMP-2) kDa...

BACKGROUND: Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are remarkably effective for treating EGFR-mutant non-small cell lung cancer (NSCLC). However, the individual role of EGFR-TKIs in patients with brain metastasis (BM) arising from EGFR-mutant NSCLC remains unclear. METHODS: Patients with BM secondary to NSCLC and harboring EGFR-activating mutations were retrospectively screened. Patients who received gefitinib or erlotinib to control both extracranial lesions (ECLs) and intracranial lesions (ICLs) were eligible...

BACKGROUND: Minimally-invasive approaches are attractive alternative to standard craniotomy for large intracranial tumors with potentially lesser morbidity. In this report, we describe a sequential combination of two minimally-invasive surgical techniques to treat a large intracranial tumor. CLINICAL PRESENTATION: A 49year-old woman presented with a history of breast cancer and large left parietal metastasis with significant perilesional edema. This was initially managed by whole brain radiation therapy and stereotactic radiosurgery...

The outcome of recurrent brain metastasis is dismal. This study aims to assess the clinical outcomes and toxicity of reirradiation as a salvage treatment for progressive brain metastasis in patients with advanced breast cancer. Between July 2005 and September 2014, the medical records of 56 patients with brain metastasis from breast cancer were retrospectively reviewed. Of these patients, 39 received whole-brain radiotherapy (WBRT) followed by stereotactic radiosurgery (SRS) reirradiation (Group 1), and 17 received SRS followed by WBRT reirradiation (Group 2)...

Glioblastoma multiforme (GBM) is the most common and the most malignant primary intracranial tumor in adults and it is usually occurs between the age of 40 and 60 years. It is local invasive and recurrent tumor and hence that has a poor prognosis. However, recent advances in tumor surgery, irradiation and chemotherapeutic agent permit long survival and metastasis which is symptomatic. Previously studies reported spinal metastasis, but we report a first case of synchronous symptomatic cerebellar and cervical spinal metastasis after resection of symptomatic thoracic spinal metastasis from temporal GBM without any recurrence of excision areas...

OBJECTIVE Laser interstitial thermal therapy (LITT), sometimes referred to as "stereotactic laser ablation," has demonstrated utility in a subset of high-risk surgical patients with difficult to access (DTA) intracranial neoplasms. However, the treatment of tumors larger than 10 cm(3) is associated with suboptimal outcomes and morbidity. This may limit the utility of LITT in dealing with precisely those large or deep tumors that are most difficult to treat with conventional approaches. Recently, several groups have reported on minimally invasive transsulcal approaches utilizing tubular retracting systems...
