BACKGROUND: Ventriculoperitoneal shunt (VPS) placement has been implicated in extraneural metastasis of many primary central nervous system tumors. Reported cases include, but are not limited to, medulloblastoma, germ cell tumor, astrocytoma, oligodendroglioma, lymphoma, ependymoma, melanoma, and choroid plexus tumors. However, a literature review reveals no reported cases of extraneural metastasis of solitary fibrous tumor/hemangiopericytoma (SFT/HPC). CASE DESCRIPTION: Here we report the case of a 34-year-old man with recurrent intracranial malignant SFT/HPC who had undergone surgical tumor resection and subsequent placement of a VPS for obstructive hydrocephalus in 2004...

Neoplastic leptomeningeal disease (LMD) represents infiltration of the leptomeninges by tumor cells. Knowledge of the frequencies of locations of LMD on MRI may assist in early detection, help elucidate the process of leptomeningeal spread of cancer and understand how LMD affects the central nervous system. Our goal was to identify intracranial sites of neoplastic LMD predilection on MRI in patients with cytologically-proven LMD. The presence of FLAIR signal hyperintensity and T1-weighted post-contrast enhancement in the sulci of the supratentorial compartment and cerebellum and enhancement of the cranial nerves (CNs), basal cisterns, pituitary stalk, and ependymal surface of the lateral ventricles, as well as the presence of parenchymal metastasis were recorded...

Leptomeningeal carcinomatosis is a devastating disease. Despite its numerous complications, intrathecal (IT) chemotherapy remains a longstanding treatment for leptomeningeal carcinomatosis. Using case studies with internationally reported results, we attempted to determine the necessity of IT chemotherapy in treating leptomeningeal carcinomatosis. We conducted a systematic review and pooled analysis to compare hormone therapy, chemotherapy, and IT therapy. We excluded articles on IT trastuzumab therapy. We performed our literature search without language restriction...

INTRODUCTION: Tumours of central nervous system constitute 1%-2% of tumours in adults. The incidence of brain tumours has been reported to be around 3.9 and 3.0/one lac/year in males and females respectively. A few studies are available from India which show a lower incidence of brain tumours compared to the developed countries. Not much is known about the epidemiology of brain tumours in the population from South India. AIM: To identify the age groups, gender distribution, topography and different histological types of brain tumours...

Objective: As solitary fibrous tumor (SFT) and hemangiopericytoma (HPC) share the same molecular genetics features, the 2016 WHO classification of central nervous system (CNS) tumors had created the combined term SFT/HPC and assigns three grades. This study aims to investigate the clinicopathologic characteristics, diagnosis, differential diagnosis and prognosis of CNS SFT/HPC. Methods: Seventy-one cases of CNS SFT and HPC were retrospectively reclassified and studied. Histopathological, immunohistochemical and imaging features were analyzed...

Glioblastoma multiforme (GBM) is the most common and aggressive brain tumor subtype. Despite that metastasis of GBM beyond the central nervous system (CNS) is rare, its malignancy is attributed to the highly infiltration trait, leading to the difficulty of complete surgical excision. Matrix gla protein (MGP) is a vitamin K-dependent small secretory protein, and functions as a calcification inhibitor. The involvement of MGP function in glioma cell dynamics remains to be clarified. The study showed that a low proliferative rat C6 glioma cell line named as C6-2 exhibited faster migratory and invasive capability compared to that observed in a high tumorigenic rat C6 glioma cell line (called as C6-1)...

WHAT IS KNOWN AND OBJECTIVE: Anaplastic lymphoma kinase (ALK)-rearranged non-small-cell lung cancer (NSCLC) is a distinct subtype with patients showing peculiar clinicopathological features and dramatic responses to the ALK tyrosine kinase inhibitor crizotinib. Patients with this cancer variant have a dismal prognosis and limited treatment options when it has progressed to intracranial metastasis because of inadequate drug penetration into the central nervous system (CNS). Factors associated with response to TKI therapy have been reported to include pharmacokinetic and biodynamic resistance phenomena...

INTRODUCTION: Isolated optic nerve metastases are extremely uncommon. Many cases are associated with involvement from locations such as the choroid, orbit, or central nervous system. Optic nerve metastases often have their origin in primary tumours of the breast, lung, and stomach, in adults. CASE REPORT: The case is presented of a 57 year-old woman with a diagnosis of lung adenocarcinoma. Her first complaint was a sudden loss of visual acuity in her right eye. The diagnosis of optic nerve metastases was made based on her history, and the results of the MRI scan...

Central nervous system (CNS ) metastasis is not only an increasing but still a very unsatisfying clinical problem, with very few treatment options nowadays and an unmet clinical need. Additionally, the patients suffer from severe neurological symptoms. Furthermore the preclinical studies are limited and thus innovative methods are needed to study the mechanism of CNS metastasis during the final steps. Especially nowadays, the most critical step during metastasis seems to be the contention of the microenvironment of host organs with the cancer cells coming from other organs...

Glioma is the most common form of primary malignant tumor that occurs in the central nervous system. The underlying molecular mechanism of the carcinogenesis and progression of glioma remains to be elucidated. It is well‑established that microRNAs (miRs) are associated with the regulation of glioma initiation and progression, and may represent a novel effective therapeutic strategy for the treatment of glioma. In the present study, the expression, roles and molecular mechanisms of miR‑205 in glioma were investigated...

Glioma is the most common malignant tumor of the central nervous system, with a low survival rate of five years worldwide. Although high expression and prognostic value of histone deacetylase 1 (HDAC1) have been recently reported in various types of human tumors, the molecular mechanism underlying the biological function of HDAC1 in glioma is still unclear. We found that HDAC1 was elevated in glioma tissues and cell lines. HDAC1 expression was closely related with pathological grade and overall survival of patients with gliomas...

In pediatric brain tumours, dissemination of malignant cells within the central nervous system confers poor prognosis and determines treatment intensity, but is often undetectable by imaging or cytology. This study describes the use of fluorescence lifetime (FLT) imaging microscopy (FLIM), a novel diagnostic tool, for detection of metastatic spread. The study group included 15 children with medulloblastoma and 2 with atypical teratoid/rhabdoid tumour. Cells extracted from the tumour and the cerebrospinal fluid (CSF) 2 weeks postoperatively and repeatedly during chemo/radiotherapy were subjected to nuclear staining followed by FLT measurement and cytological study...

Seeding of a central nervous system malignancy to the abdominal cavity is an uncommon but well documented complication of a ventriculoperitoneal (VP) shunt. However, the metastasis of a primary gastrointestinal cancer to the skin via a VP shunt is extremely rare. We report the clinical case of an 85-year-old male who presented with a right upper quadrant nodule over his shunt, which on histopathology and tumour marker profile was diagnosed as an adenocarcinoma of likely upper gastrointestinal origin. This case illustrates the importance of proceeding to biopsy to inform prognosis and management, despite the risks of shunt infection...

Non-small cell lung cancer (NSCLC) ranks as the leading cause of cancer-related death in the world. Brain metastasis (BM) is a common complication of NSCLC, with 25%-40% of patients developing BM during the course of the disease. A significant strategy of local disease control in the central nervous system is radiation therapy. With the development of precision medicine, the concept of treating lung cancer BM has gradually changed. In this case, we performed a surgical procedure to obtain enough tumor tissue for the detection of the target gene and other related experiments after the patient was informed...

Brain metastasis is the most frequent central nervous system malignancy. Although surgery and chemotherapy have roles to play in the treatment of brain metastasis, radiation therapy remains a mainstay of therapy. We will review the role of fractionated radiotherapy and stereotactic radiosurgery in the treatment of newly diagnosed and recurrent brain metastasis.
