We present the case report of a twenty-five-year-old Moroccan male patient who suffered from leptomeningeal carcinomatosis related to a signet-ring cell carcinoma of the rectum. He presented to the emergency department with abdominal pain, constipation, weight loss and rectal bleeding. The rectal examination showed a rectal tumor and a CT scan revealed a large bowel obstruction due to rectal diffuse thickening. An emergency transverse colostomy was performed, with a rectal biopsy and a cytological sample collection...

Melanocytes, the cells responsible for skin pigmentation, are present in other parts of the body, such as the ocular, auditory, nervous, and cardiac systems. Within these systems, their roles serve a different purpose than their classical counterparts in skin as pigment cells. Such roles include cell turnover in retinal pigment epithelium, maintenance of balance and prevention of environmental damage in the auditory neuroepithelium, role-playing as dendritic cells within the leptomeninges, and prevention of oxidative damage in adipose tissue...

We report a case of primary central nervous system vasculitis (PCNSV) mimicking a cortical brain tumor. A 25-year-old woman presented with a 2-week history of headache and transient right hemiparesis. Brain magnetic resonance imaging (MRI) revealed a cortical-involving lesion on the left frontal lobe. The 6-cm sized lesion showed low signal intensity on T1-weighted images and high signal intensity on T2-weighted images. The lesion had continual linear enhancement on the subcortical white matter and leptomeninges...

The authors describe an immunocompetent, 50-year-old man who complained of a daily transient blurring of his vision with bilateral papilloedema. His visual acuity was 20/20 OU, and the blind spot was enlarged bilaterally. There was intracranial hypertension, but imaging for systemic and brain tumours were negative. These findings suggested a diagnosis of the pseudotumor syndrome. However, MRI showed leptomeningeal enhancement, and acetazolamide successfully resolved his visual symptoms and papilloedema. Cytology and flow cytometry of the CSF led to the final diagnosis of primary leptomeningeal lymphoma (PLML)...

Intracranial glioblastoma multiforme (GBM) constitutes the most frequent and unfortunately aggressive primary central nervous system malignancy. Despite the high tendency of these tumors to show local relapse within the brain after primary therapy, dissemination into the spinal axis is an infrequent event. If spinal metastases occur they are leptomeningeal in the vast majority of cases and always in the context of intracranial progressive disease. Spinal intramedullary metastases of intracranial GBM have rarely been described to date...

PURPOSE: Prior studies suggest a high incidence of leptomeningeal failure (LMF) in breast cancer metastatic to brain. This study examines breast cancer-specific variables affecting development of LMF and survival after Gamma-Knife Radiosurgery (GKS). METHODS: Between 2000-2010, 149 (breast) and 658 other-histology patients were treated with GKS. Hormone/HER2, age, local/distant brain failure, prior craniotomy, and prior whole-brain radiotherapy (WBRT) were assessed...

Ovarian cancer, a leading cause of death in women, typically spreads locally and rarely metastasizes to the brain or seeds the leptomeninges. We present a case of a 62-year-old woman with a history of treated ovarian cell carcinoma who developed bilateral sensorineural deafness and right-sided facial weakness and on imaging was found to have bilateral internal auditory canal (IAC) masses and leptomeningeal carcinomatosis, pathologically proven by cerebrospinal fluid cytology. We discuss her magnetic resonance imaging and positron emission tomography-computed tomography findings and review the imaging characteristics of IAC metastases...

Medulloblastoma (MB) arising from the cerebellum is the most common pediatric brain malignancy, with leptomeningeal metastases often present at diagnosis and recurrence associated with poor clinical outcome. In this study, we employed mouse MB models to explore the relationship of tumor pathophysiology and dysregulated expression of the Notch pathway transcription factor ATOH1, which is present in aggressive MB subtypes driven by aberrant Sonic Hedgehog/Patched (SHH/PTCH) signaling. In experiments with conditional Atoh1 mouse mutants crossed to Ptch1(+/-) mice which develop SHH-driven MB[63], animals with Atoh1 transgene expression developed highly penetrant MB at a young age with extensive leptomeningeal disease and metastasis to the spinal cord and brain, resembling xenografts of human SHH MB...

An imaging case is presented on a patient referred to our department for an (18)F-FDG-PET/CT, as a paraneoplastic syndrome was suspected due to his clinical situation. He had a history of acute myeloid leukemia (AML) treated two years earlier, with sustained complete remission to date. (18)F-FDG-PET/CT findings revealed hypermetabolism in almost all nerve roots, suggesting meningeal spread, consistent with the subsequent MRI findings. Cerebrospinal fluid (CSF) findings confirmed a leptomeningeal reactivation of AML...

Patients with an epidermal growth factor receptor (EGFR) mutation are usually administered EGFR-tyrosine kinase inhibitors (TKIs) as standard-of-care treatment. However, acquired resistance occurs between 9 and 13 months. The T790M-resistant mutations are the most common, and osimertinib has been found to be effective in treating EGFR-T790M-positive patients. A 73-year-old female lung cancer patient with an EGFR-sensitizing mutation was receiving fourth-line chemotherapy when she complained of anorexia, headache, and irritability...

Leptomeningeal carcinomatosis (LC) is a rare and mainly secondary site of metastasis in solid tumors. In gastric cancer (GC), it is associated with a devastating prognosis, lacking an efficient and standardized treatment approach. We report a case of primary manifestation of LC due to metastatic GC with rapid deterioration and refractory course to conventional and intrathecal chemotherapy. We review the literature and discuss the therapeutic challenges.

Carcinomatous meningitis is a rare manifestation of malignancy. It is increasingly being recognized in lung carcinoma, breast carcinoma, melanomas, gastrointestinal malignancies, lymphomas, and leukemia and it is almost never seen in gallbladder malignancies. We present a case whose primary presentation was as a carcinomatous meningitis that was subsequently found to be secondary to a gallbladder primary.

Background and Purpose: Leptomeningeal collaterals maintain arterial perfusion in acute arterial occlusion but may fluctuate subject to arterial blood pressure (ABP). We aim to investigate the relationship between ABP and collaterals as assessed by computer tomography (CT) perfusion in acute ischemic stroke. Methods: We retrospectively analyzed acute anterior circulation ischemic stroke patients with CT perfusion from 2009 to 2014. Collateral status using relative filling time delay (rFTD) determined by time delay of collateral-derived contrast opacification within the Sylvian fissure, from 0 seconds to unlimited count...

Leptomeningeal metastases are a late manifestation of systemic cancer which affects up to 10% of patients with solid tumors. Prognosis is poor, and overall survival at 1 year is only approximately 10%. Management depends mainly on general and neurological condition, primary tumor, and patterns of metastasis, notably absence or presence of concurrent systemic or solid brain metastases. Here we set out to characterize current practice patterns of diagnosis and treatment of patients with leptomeningeal metastasis in Europe...

BACKGROUND: Sturge-Weber syndrome results in leptomeningeal vascular malformations, medically refractory epilepsy, stroke(s), and cognitive impairments. Cannabidiol, a cannabinoid without psychoactive properties, has been demonstrated in preclinical models to possibly have anticonvulsant, antioxidant, and neuroprotective actions. METHODS: Five subjects with Sturge-Weber syndrome brain involvement and treatment-resistant epilepsy were enrolled. Motor seizure frequency, quality of life, and adverse events were recorded from the eighth week of the pretreatment period, eight weeks after starting maintenance dose (week 14), and the most recent visit...
