Leptomeningeal metastasis is a fatal manifestation seen in advanced cancer patients. Its incidence is increasing, reaching 3.8% in molecularly unselected non-small cell lung cancer patients and up to 5% and 9% in ALK-rearranged and EGFR-mutant lung cancer patients, respectively. The prognosis remains poor despite systemic treatment, intrathecal chemotherapy, radiation therapy and personalized treatments in molecularly selected patients. However, new therapies with improved cerebral-spinal fluid penetration have been developed for subgroups of molecular selected patients indicating they could be promising therapeutic options for managing leptomeningeal disease...

CAR T cells targeting IL13Rα2 proved effective against recurrent multifocal leptomeningeal glioblastoma, according to a case report. Direct delivery of the therapy into the cerebrospinal fluid was well tolerated, completely eliminating the patient's brain and spinal tumors for 7.5 months, during which the patient resumed his normal activities.

Paraneoplastic neurological disorders are uncommon presentations of head and neck cancers. We present a case of a 68-year-old male patient who presented with dizziness, nausea and memory problems. MRI of his brain showed bilateral cerebellar leptomeningeal enhancing signal abnormality with cervical lymphadenopathy. CT imaging of his neck raised the suspicion of a tonsillar primary, which was later confirmed on biopsy. His poorly differentiated HPV positive squamous cell carcinoma was treated with chemoradiotherapy...

BACKGROUND: The clinical manifestations of neurosarcoidosis are highly variable and it should be considered as a potential differential diagnosis in any neurological presentation. AIM: This study was designed to describe the clinical, diagnostic, and treatment patterns and functional outcome in a Caucasian neurosarcoidosis population. DESIGN: A retrospective analysis was performed on prospectively recorded data in patients attending our neurology clinic between 2008 and 2014 with a diagnosis of definite or probable neurosarcoidosis according to Zajiek criteria...

Nucleic acid-editing enzymes of the apolipoprotein B mRNA-editing enzyme (APOBEC) family have been associated with somatic mutation in cancer. However, the role of APOBEC catalytic subunit 3B (APOBEC3B) editing in the pathogenesis of base substitutions in meningiomas is unknown. In the present study, the expression of APOBEC3B was examined by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot analyses in five fetal and one adult human leptomeninges and 38 meningiomas. Genomic DNA was sequenced using the Illumina Tru-Seq Cancer Panel...

Leptomeningeal carcinomatosis is rare, and its precise incidence is unknown. It is associated with a wide spectrum of solid and hematological malignancies. To complicate its diagnosis, the clinical presentation of leptomeningeal carcinomatosis can be variable. We report a case of a 38-year-old male with bilateral facial nerve paralysis as first presentation of lung adenocarcinoma. To our knowledge, this is the only case describing bilateral facial nerve palsy as the first and only manifestation of lung adenocarcinoma...

The management of brain metastases has been important in neurosurgical oncology. Resection of a brain metastasis carries an increased risk of leptomeningeal dissemination than other treatment modalities such as irradiation or pharmacotherapy. We have utilized intraoperative wash cytology of cotton patties covering the brain surface. The cytology information contributes to making a decision of postoperative whole brain radiation. We named the method as "cotton dam", that serves as a check and catch of neoplastic cells on the brain surface during resection surgery...

Hereditary cystatin C amyloid angiopathy (HCCAA) is a genetic disease caused by a mutation in the cystatin C gene. Cystatin C is abundant in cerebrospinal fluid and the most prominent pathology in HCCAA is cerebral amyloid angiopathy due to mutant cystatin C amyloid deposition with associated cerebral hemorrhages, typically in young adult carriers. Analyses of post-mortem brain samples shows that pathological changes are limited to arteries and regions adjacent to arteries. The severity of pathological changes at post-mortem has precluded the elucidation of the evolution of histological changes...

BACKGROUND: Leptomeningeal carcinomatosis is a relatively rare metastatic form of non-small cell lung cancer, which can impact prognosis. There is an increasing need for selecting suitable epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors among those currently included in standard care for EGFR mutation-positive patients. We compared the efficacy of gefitinib and erlotinib in survival of patients with leptomeningeal carcinomatosis. PATIENTS AND METHODS: The medical records of 269 patients who received tyrosine kinase inhibitors at a single center were retrospectively reviewed...

Coccidioides species are endemic to the southwestern United States and typically cause a mild or asymptomatic primary infection. In some instances, infection can disseminate and involve the central nervous system with meningitis being the most common manifestation. Non-osseous spinal cord involvement is exceedingly rare. We report a case of disseminated coccidioidomycosis in an otherwise healthy 20 year old man with diffuse leptomeningeal enhancement, cerebrospinal fluid findings suggestive of meningitis, and intramedullary spinal cord abscesses...

In the surgical case of a mature cystic teratoma of the ovary that arose in a 16-year-old girl, a large amount of well-differentiated and highly organized cerebellar tissue was found. Three layers of the cerebellar cortex were well formed, and synaptophysin-positive "glomeruli" were found in the granule cell layer. Some Purkinje cells exhibited focal expansion and a dysmorphic appearance of the dendrites. Adjacent to the cerebellar tissue, a large space lined by the ependymal layer and a club-shaped CNS tissue mass resembling the brainstem were found, and structures reminiscent of the midbrain tectum and pontine nuclei were distinguished within this mass...

Leptomeningeal metastases (LM) currently lack standardization with respect to response assessment. A Response Assessment in Neuro-Oncology (RANO) working group with expertise in LM developed a consensus proposal for evaluating patients treated for this disease. Three basic elements in assessing response in LM are proposed: a standardized neurological examination, cerebral spinal fluid (CSF) cytology or flow cytometry, and radiographic evaluation. The group recommends that all patients enrolling in clinical trials undergo CSF analysis (cytology in all cancers; flow cytometry in hematologic cancers), complete contrast-enhanced neuraxis MRI, and in instances of planned intra-CSF therapy, radioisotope CSF flow studies...

Leptomeningeal metastases occur in 1% of patients with non-small-cell lung cancer. There have been several reports on the treatment of leptomeningeal metastases with afatinib. Our patient was a 41-year-old woman who had never smoked and was diagnosed with stage IV adenocarcinoma of the lung with an epidermal growth factor receptor (EGFR) mutation. She was treated with afatinib for the recurrence of leptomeningeal metastases. After the treatment with afatinib was initiated, the neurological symptoms dramatically regressed, and she achieved progression-free survival for 7 months...

The occurrence of secondary EGFR mutation T790M in exon 20 and histologic "transformation" are common mechanisms underlying resistance to EGFR first- or second-generation tyrosine kinase inhibitors (TKI). We describe here on a hitherto unreported mechanism of EGFR TKI resistance synchronously combining squamous-cell carcinoma change and occurrence of the EGFR exon 20 S768I secondary mutation in a 43 year-old woman with stage IV adenocarcinoma harbouring EGFR exon 21 L858R mutation. After 8 months of response to gefitinib, the patient experienced EGFR TKI resistance and died of leptomeningeal neoplastic dissemination...

Ischaemic neuropathological changes associated with Cytauxzoon felis infection in cats have been reported recently. This paper describes the associated glial changes and the evidence for apoptosis in the brain of cats infected naturally by C. felis. Sections of brain from eight affected cats and eight age- and sex-matched control cats were evaluated by immunohistochemistry for expression of glial fibrillary acidic protein, CD18 and cleaved caspase-3. Vascular changes in the leptomeninges and parenchyma, the number of positive astrocytes and phagocytic cells (microglia or macrophages) and the average astrocytic cytoplasmic area and number and length of astrocytic processes were quantified, and a mean value for the grey and white matter in both groups was generated...

At diagnosis of the cerebral and spinal tuberculous meningitis magnetic resonance (MR) imaging is the primary imaging technique. Magnetic resonance images reveal cerebrospinal fluid collection and obliteration of the spinal subarachnoid space. The contrast-enhanced MR imaging shows nodular and thick intradural enhancement. Herein, the authors reported advanced MR imaging findings of the cerebral and spinal tuberculous leptomeningitis.
