BACKGROUND: Leptomeningeal metastasis (LM) is an uncommon form of metastatic disease in many cancers. There remains a paucity of literature with regard to the course and management of LM in colorectal cancers (CRCs). The aim of this study was to estimate the incidence of LM in patients with CRC seen at our institution over a 15-year period, and to describe the clinical course and outcome of these cases. METHODS: LM in CRC primary cases between 2000 and 2014 were identified in the Mayo Clinic databases...

Background: There is controversy about the global distribution of intracranial tumors (ICTs). The previous reports from Africa suggested low frequency and different pattern of distribution of brain tumors from what obtains in other continents. The limitations at that time, including paucity of diagnostic facilities and personnel, have improved. Objective: The objective of this study is to analyze the current trend and distribution of histology confirmed brain tumors managed in Enugu, in a decade...

Myeloid sarcoma, a rare consequence of myeloproliferative disorders, is rarely seen in the central nervous system, most commonly in the pediatric population. Although there are a handful of case reports detailing initial presentation of CNS myeloid sarcoma in the adult population, we have been unable to find any reports of CNS myeloid sarcoma presenting as a large mass lesion in a herniating patient. Here, we present the case of a patient transferred to our facility for a very large subdural hematoma. Based on imaging characteristics, it was felt to be a spontaneous hematoma secondary to coagulopathy...

Melanoma is the most lethal of skin cancers, in part because of its proclivity for rapid and distant metastasis. It is also potentially the most neurotropic cancer in terms of probability of CNS metastasis from the primary lesion. Despite surgical resection and radiotherapy, prognosis remains guarded for patients with brain metastases. Over the past five years, a new domain of personalized therapy has emerged for advanced melanoma patients with the introduction of BRAF and other MAP kinase pathway inhibitors, immunotherapy, and combinatory therapeutic strategies...

The goal of the study is to examine the practice pattern and survival outcome of adult and pediatric patients with intracranial germinoma. Patients from the National Cancer Database (NCDB) brain tumor registry between the years 2004-2014 with intracranial germinoma were extracted for analysis. Patients who had distant metastasis, received no treatments, or only surgery/chemotherapy alone were excluded. An age cutoff of > 21 years old was used to define the pediatric population. Patients were stratified by the treatments radiation therapy alone (RT) and chemotherapy followed by radiation therapy (C + RT)...

BACKGROUND: Brain metastases are observable in 20-40% of non-small cell lung cancer patients, but standard treatments for such metastases may be intolerable to some. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) were found to be effective against mutant-EGFR lung adenocarcinomas, but data regarding their effectiveness, especially for the second-generation EGFR-TKI afatinib, is limited. This study compared key outcomes for afatanib monotherapy versus afatinib combined with whole-brain radiotherapy (WBRT) in treatment-naïve lung adenocarcinoma patients harboring EGFR mutations...

Patients with primary or metastatic brain tumors are at increased risk of developing venous thromboses. However, the potential benefit of therapeutic anticoagulation in these patients must be weighed against the deadly complication of intracranial hemorrhage. In this review, we summarize available evidence and recent studies of intracranial bleeding risks in primary and metastatic tumors and the impact of therapeutic anticoagulation. We find that for the majority of primary and treated metastatic brain tumors, the risk of spontaneous bleeding is acceptable and not further increased by careful therapeutic anticoagulation with low molecular weight heparin or direct oral anticoagulants, although thrombocytopenia (platelet count less than 50,000/μL) and other coagulopathies are relative contraindications...

Primary brain tumors comprise 28% of all tumors and 80% of malignant tumors. Pathophysiology of high-grade gliomas includes significant distortion of white matter architecture, necrosis, the breakdown of the blood brain barrier, and increased intracranial pressure. Diffusion tensor imaging (DTI), a diffusion weighted imaging technique, can be used to assess white matter architecture. Use of DTI as a non-invasive pathophysiological tool to analyze glioma impact on white matter microstructure has yet to be fully explored...

RATIONALE: Garcin syndrome is characterized by the gradual involvement, and ultimately, unilateral paralysis of at least 7 and sometimes all cranial nerves, without intracranial hypertension or any long tract signs. PATIENT CONCERNS: We report the case of a 59-year-old woman who presented with Garcin syndrome, which gradually progressed over a period of 2 years. DIAGNOSIS: A left parotid gland biopsy revealed parotid gland adenoid cystic carcinoma (PGACC) with perineural invasion of a peripheral nerve bundle and lymph node metastasis...

BACKGROUND AND PURPOSE: To prospectively evaluate hippocampal radiation dose volume effects and memory decline following cranial irradiation. MATERIAL AND METHODS: Effects of hippocampal radiation over a wide range of doses were investigated by combining data from three prospective studies. In one, adults with small cell lung cancer received hippocampal-avoidance prophylactic cranial irradiation. In the other two, adults with glioblastoma multiforme received neural progenitor cell sparing radiation or no sparing with extra dose delivered to subventricular zone...

Volumetric Modulated Arc Therapy (VMAT) techniques for fractioned stereotactic brain radiotherapy (FSBRT) can achieve highly conformal dose distribution to intracranial lesions. However, they can potentially increase the dose to hippocampus (H) causing neurocognitive toxicity during the first four months after irradiation. The purpose of this study was to assess the feasibility of hippocampal-sparing (HS) treatment plans in 22 patients with brain metastasis treated with VMAT technique. Firstly, we retrospectively analyzed hippocampal doses in all 22 VMAT original (not hippocampal-sparing, NHS) plans...

We report a case of renal cell carcinoma (RCC) metastasis to the calvarium and describe a strategy for percutaneous embolization of hypervascular calvarial tumors with intracranial extension. An elderly patient with history of RCC presented with left-sided weakness. Imaging studies showed a large right frontoparietal calvarial mass with intra- and extracranial extension. The tumor was devascularized by direct puncture tumor embolization using Onyx 18, allowing subsequent operative resection without significant blood loss or the need for flap reconstruction of the scalp...

Sixth nerve palsy is frequently due to infectious orbital lesions, trauma, elevated intracranial pressure, brainstem lesions, and vasculopathies. Here, we describe a rare cause of sixth cranial nerve (CN) palsy secondary to calvarial and orbital metastasis of prostate carcinoma. The diagnosis of the prostate carcinoma with sixth CN palsy is a very rare condition. A 66-year-old male patient presented with complaints of blurred vision, double vision, and inability to move outward in the right eye for 3 weeks...

Meningioma is a common intracranial and intraspinal neoplasm accounting for 25-30% of all primary neurological tumours. It is associated with high rates of recurrence especially in higher-grade tumours and lesions located at the skull base. Cancer stem cells are increasingly recognised as the origin of cancer and are attributed to loco-regional recurrence, metastasis and treatment resistance. This review presents the accumulating evidence of the presence of tumour stem cells within meningioma and the stem cell markers being used to characterise this putative primitive population within this common tumour...

Malignant brain tumors, including gliomas, brain metastases and anaplastic meningiomas, are associated with poor prognosis, and represent an unmet medical need. ASA404 (DMXAA), a vascular disrupting agent, has demonstrated promising results in several preclinical tumor models and early phase clinical trials. However, two phase III trials in non-small cell lung cancer reported insufficient results. The aim of the present study was to determine the effects of ASA404 on brain tumors. The effects of ASA404 were evaluated in vitro and in vivo using subcutaneous, and orthotopical models for malignant glioma (U-87, LN-229, U-251, LN-308 and Tu-2449), brain metastasis (HT-29) and malignant meningioma (IOMM-Lee)...

PURPOSE: Metastasis to the brain from breast cancer remains a significant clinical challenge, and may be targeted with CAR-based immunotherapy. CAR design optimization for solid tumors is crucial due to the absence of truly restricted antigen expression and potential safety concerns with "on-target off-tumor" activity. Here, we have optimized HER2-CAR T cells for the treatment of breast to brain metastases, and determined optimal second generation CAR design and route of administration for xenograft mouse models of breast metastatic brain tumors, including multifocal and leptomeningeal disease...

Basosquamous carcinoma is a rare, highly aggressive variant of basal cell carcinoma with elevated rates of recurrence, perineural invasion, and metastasis. We describe a patient who presented with unilateral complete ophthalmoplegia, ptosis, optic neuropathy, and trigeminal neuropathy due to perineural intracranial invasion of nasal basosquamous carcinoma via the sphenopalatine fossa to the cavernous sinus, orbit, and infratemporal fossa. To our knowledge, this is the first reported case of basosquamous carcinoma with perineural invasion involving the cavernous sinus in the English language ophthalmic literature...

In adults, meningiomas occasionally display aggressive behavior and may occasionally metastasize. By contrast, pediatric meningiomas are rare, and there is limited information regarding their clinical characteristics, treatment and prognosis. We herein report the case of a 3-year-old boy with anaplastic meningioma with a history of local recurrence and late pulmonary metastasis. At diagnosis, a 70-mm mass lesion in was identified in the right frontal lobe, with intratumoral hemorrhage. The tumor was attached to the falx cerebri and was completely resected...
