Medulloblastoma is the most common malignant brain tumor of childhood. Group 3 medulloblastoma, the most aggressive molecular subtype, frequently disseminates through the leptomeningeal cerebral spinal fluid (CSF) spaces in the brain and spinal cord. The mechanism of dissemination through the CSF remains poorly understood, and the molecular pathways involved in medulloblastoma metastasis and self-renewal are largely unknown. Here we show that NOTCH1 signaling pathway regulates both the initiation of metastasis and the self-renewal of medulloblastoma...

Background: Myxopapillary ependymoma (MPE) with anaplastic features is extremely rare, with only three case reports in the literature. Case Description: We report the case of a MPE with anaplastic features in a 24-year-old female who presented with a dominant lumbar mass along with intracranial and sacral metastases. Upon gross total resection of the dominant tumor located at L2-L3, it appeared to arise from the filum terminale, and had a solid component in addition to soft or necrotic areas...

Extraneural metastasis (ENM) of primary central nervous system (CNS) tumors is an uncommon occurrence. Case reports and case series describe ENM after shunting, but this phenomenon has not been well characterized. In this review we aim to better understand the risk factors and clinical implications of ENM associated with shunting. A literature search of cases of ENM related to shunt placement in patients with primary CNS tumors reported through January 2018 was performed using PubMed and Google Scholar. We identified 106 cases of ENM of primary CNS tumors related to shunt placement...

Cauda equine syndrome (CES) is a neurological condition caused by compression of the cauda equine. Here, we demonstrate a case of CES as the primary symptom of leptomeningeal metastases from non-small cell lung carcinoma without brain metastases. A 59-year-old male suffered progressive lower extremity motor dysfunction, urinary dysfunction, and lower extremity sensory dysfunction. He was clinically diagnosed with CES. Nuclear magnetic resonance imaging demonstrated several vague nodules in the area of conus medullaris and cauda equine, without lumbar or thoracic herniated discs...

OBJECTIVE: Stereotactic radiosurgery (SRS) has redefined the treatment paradigm for cerebral metastases. The benefits of SRS after surgical resection of a metastatic brain tumor have been well-defined. However, it is unclear whether preoperative SRS can improve the outcomes in select patients. The present study examined the safety and efficacy of preoperative neoadjuvant SRS (NaSRS) for the treatment of cerebral metastases. METHODS: We performed a retrospective review of 12 patients treated at The University of Texas Southwestern Medical Center...

BACKGROUND: Group 3 tumors account for approximately 25-30% of medulloblastomas and have the worst prognosis. UAB30 is a novel synthetic rexinoid shown to have limited toxicities in humans and significant efficacy in the pediatric neuroectodermal tumor, neuroblastoma. We hypothesized that treatment with UAB30 would decrease tumorigenicity in medulloblastoma patient-derived xenografts (PDXs). METHODS: Three group 3 medulloblastoma PDXs (D341, D384 and D425) were utilized...

Rationale: Leptomeningeal metastasis (LM) is an important cause of mortality in patients with non-small cell lung cancer (NSCLC). As the symptoms of LM and its early clinical manifestations are nonspecific, early diagnosis of LM is difficult. However, there are few treatment options for LM, which leads to a poor prognosis; thus, increased clinical attention is necessary. The effects of most systemic chemotherapies on metastatic brain tumors (brain metastases and LMs) are limited as they cannot pass the blood-brain barrier; therefore, whole-brain radiation therapy is a therapeutic option...

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are effective in the treatment of advanced non-small-cell lung cancer (NSCLC) with leptomeningeal metastases (LM); however, a proportion of the patients with resistant tumors do not benefit from EGFR-TKI treatment. In the present study the case of a female patient with advanced lung adenocarcinoma harboring the EGFR L858R mutation (encoded in exon 21) who developed intracranial metastases following treatment with erlotinib after gefitinib failure is reported...

Brain metastasis is a serious complication in patients with systemic cancer. The main goal of the treatment in patients with brain metastasis is to control the disease in the brain, to prevent death from neurological disease and provide a satisfactory quality of life. Management of a patient with brain metastasis is important and sometimes demanding, and several factors such as tumor histology, status of primary disease, number of brain lesions, size of lesions, and performance status may influence the decision making process...

Acute lymphoblastic leukaemia (ALL) has a marked propensity to metastasize to the central nervous system (CNS). In contrast to brain metastases from solid tumours, metastases of ALL seldom involve the parenchyma but are isolated to the leptomeninges, which is an infrequent site for carcinomatous invasion. Although metastasis to the CNS occurs across all subtypes of ALL, a unifying mechanism for invasion has not yet been determined. Here we show that ALL cells in the circulation are unable to breach the blood-brain barrier in mice; instead, they migrate into the CNS along vessels that pass directly between vertebral or calvarial bone marrow and the subarachnoid space...

Leptomeningeal metastasis (LM), which occurs when malignant cells spread to the central nervous system, is becoming an increasingly common complication in patients with breast cancer. Diagnosis and treatment of LM is challenging. Moreover, prognosis of patients with LM is poor, with a median survival of 6 months after diagnosis. This review highlights the strengths and limitations of currently available diagnostic tools and therapies for LM. The current treatments for LM, including radiotherapy, systemic therapy, and intrathecal treatment, aim to maintain the quality of life of patients by correcting neurological deficits and arresting neurological degeneration...

Pure seminoma is a histological subtype of testicular cancer that accounts for 50% of testicular germ cell tumors. It has a very low rate of metastasis to the central nervous system, with only one previously reported case of neoplastic meningitis (cancer that has spread to the cerebrospinal fluid). Traditionally, neoplastic meningitis has an ominous prognosis when associated with primary tumors that commonly spread to the leptomeninges, like breast and lung. This article highlights a unique case of pure seminoma with neoplastic meningitis and illustrates the effectiveness of craniospinal irradiation as a treatment modality...

BACKGROUND AND PURPOSE: Contrast-enhanced 3D fast spin-echo T1 black-blood imaging selectively suppresses the signal of blood flow and could provide a higher contrast-to-noise ratio compared with contrast-enhanced 3D ultrafast gradient recalled echo (contrast-enhanced gradient recalled echo) and 2D spin-echo T1WI (contrast-enhanced spin-echo). The purpose of our study was to evaluate whether black-blood imaging can improve the diagnostic accuracy for leptomeningeal carcinomatosis compared with contrast-enhanced gradient recalled-echo and contrast-enhanced spin-echo and, furthermore, to determine whether the grade of leptomeningeal carcinomatosis evaluated on black-blood imaging is a significant predictor of progression-free survival...

In this study, we examined the characteristics and aimed to increase the knowledge of clinical features of leptomeningeal metastasis (LM). The clinical data, including initial diagnosis and treatment of primary tumor, clinical manifestations, neuroimaging findings, cerebrospinal fluid (CSF) examination, were analyzed. For the patients with adenocarcinoma/breast cancer, the incidence of cranial lesions and cranial nerve paralysis was obviously higher than patients with small cell lung cancer. Whereas, the incidence of involvement of intravertebral canal was obviously lower than that of small cell lung cancer...
