BACKGROUND AND PURPOSE: Using an extended CT perfusion acquisition (150s), we sought to determine the association between perfusion parameters and malignant edema after ischemic stroke. METHODS: Patients (from prospective study PROVE-IT, NCT02184936) with terminal internal carotid artery±proximal middle cerebral occlusion were involved. CTA was assessed for clot location and status of leptomeningeal collaterals. The following CTP parameters were calculated within the ischemic territory and contralaterally: permeability surface area product (PS), cerebral blood flow (CBF) and cerebral blood volume (CBV)...

AIMS: Growing skull fracture (GSF) is a rare complication resulting from diastatic enlargement of a pediatric skull fracture. Orbitocranial GSF is a distinct variant with more complex management issues due to the displacement of the globe. This study aims to discuss surgical considerations in the management of GSF, with particular reference to orbitocranial variants. METHODS: We conducted a retrospective analysis of 7 children operated for GSFs at our institute from 2008 to 2015...

BACKGROUND: The role of cortical lesions (CLs) in disease progression and clinical deficits is increasingly recognized in multiple sclerosis (MS); however the origin of CLs in MS still remains unclear. OBJECTIVE: Here, we report a para-sulcal CL detected two years after diagnosis in a relapsing-remitting MS (RRMS) patient without manifestation of clinical deficit. METHODS: Ultra-high field (7T) MR imaging using magnetization-prepared 2 rapid acquisition gradient echoes (MP2RAGE) sequence was performed...

Primary melanocytic tumours of the central nervous system (CNS) are rare. According to the WHO classification (2007), these tumours include diffuse leptomeningeal melanosis, melanomatosis, melanocytoma, and primary CNS melanoma. Meningeal melanocytoma, most commonly seen in the infratentorial compartment and cervical spinal cord, is a benign primary melanocytic neoplasm. Primary CNS melanoma, on the other hand, represents the malignant end of the spectrum. Intermediate grade melanocytoma is a rare histological subtype of primary meningeal tumours and is characterised by the clinicopathological features between the two extremes...

Malignant infiltration of pia and arachnoid mater, referred to as leptomeningeal carcinomatosis (LMC), is a rare complication of gastric carcinoma. The most common underlying malignancy in patients with LMC are leukemia, breast cancer, lymphoma, and lung cancer. We report a case of gastric adenocarcinoma that presented with LMC in the absence of overt gastrointestinal signs or symptoms. A 56-year-old Hispanic woman presented to the hospital with a three-week history of intermittent headaches and visual blurring...

BACKGROUND: Cancer is a mosaic of tumor cell subpopulations, where only a minority is responsible for disease recurrence and cancer invasiveness. We focused on one of the most aggressive circulating tumor cells (CTCs) which, from the primitive tumor, spreads to the central nervous system (CNS), evaluating the expression of prognostic and putative cancer stem cell markers in breast cancer (BC) leptomeningeal metastasis (LM). METHODS: Flow cytometry immunophenotypic analysis of cerebrospinal fluid (CSF) samples (4...

OBJECTIVE: Relapse of ependymoma in childhood portends a grave prognosis. While the detection of local recurrence is usually simple, spotting leptomeningeal metastasis might be challenging. We aimed to evaluate possible "hotspots" where metastasis tend to appear. MATERIALS AND METHODS: Medical records and Magnetic Resonance (MR) studies of all patients diagnosed with brain ependymomas between the years 2000-2015 were reviewed. RESULTS: Leptomeningeal spread was detected among 42% of relapsed patients...

Gap junctions between cells in the pineal gland have been described ultrastructurally, but their connexin constituents have not been fully characterized. We used immunofluorescence in combination with markers of pineal cells to document the cellular localization of connexin43 (Cx43). Immunofluorescence labelling of Cx43 with several different antibodies was widely distributed throughout the pineal, whereas another connexin examined, connexin26, was not found in pineal but only in surrounding leptomeninges. Labelling apparently associated with plasma membranes was visualized either as fine Cx43-puncta (1-2 μm) or as unusually large pools of Cx43 ranging up to 4-7 μm in diameter or length...

BACKGROUND: Although the diagnosis of subdural hematoma is usually straightforward, occasionally it may be erroneous, leading to mistakes in the treatment. For example, leptomeningeal malignancies, even in the absence of bleeding, may clinically and radiologically mimic subdural hemorrhage. OBJECTIVE: To stress the importance of not only intuitive thinking but also in analytic thinking in appropriate and accurate treatment strategies. METHODS AND ILLUSTRATIVE CASE: In this report, the clinical and radiological pitfalls in differentiating malignant leptomeningeal infiltration and subdural hematomas are discussed...

INTRODUCTION: Diffuse leptomeningeal glioneuronal tumor is a new entity under the neuronal and mixed neuronal-glial tumors in the WHO 2016 updated classification and commonly found in children and adolescents. The initial diagnosis is challenging because of its non-specific radiologic feature and negative CSF cytology analysis. A 17 years male was presented with intractable headache subsequently followed by back pain and joint pain. MRI showed enhancement of arachnoid membrane at basal cistern, bilateral sylvian fissure and cerebral cistern with slight enlargement of ventricles...

Froin's syndrome is characterized by a combination of marked coagulation, elevated protein levels, and xanthochromia of the cerebrospinal fluid (CSF). It is due to blockage of CSF flow by a spinal cord mass or results from meningeal irritation during meningitis. However, Froin's syndrome has not been reported in hematological malignancies. Herein, we present two cases of lymphomatous leptomeningitis with Froin's syndrome. A 66-year-old man suffered consciousness disturbance during chemotherapy for a relapse of peripheral T-cell lymphoma, not otherwise specified...

OBJECTIVES: Several studies have shown that meningeal abnormalities with contrast enhancement go undetected in routine post contrast MPRAGE images. This study was to assess theusefulness of newer 3D T1-SPACE and 3D T2-FLAIR sequences in evaluation of meningeal abnormalities. METHODS: 78 patients presented with high suspicion of meningeal abnormalities were evaluated with post contrast 3D T2-FLAIR, 3D T1 MPRAGE and 3D T1 SPACE sequences. The images were evaluated independently by two radiologists for cortical gyral, sulcal space, basal cisterns and dural enhancement...

Spinal glioblastoma multiforme is not common among spinal cord tumors. According to our literature review, only 27 cases originating from the conus medullaris were reported. We herein reported a case of a 10-year-old child diagnosed with glioblastoma multiforme. The patient received adjuvant radiotherapy and standard temozolomide chemotherapy after total excision. Intracranial lesions were found 1 month after postoperative adjuvant therapy. We described the clinical characteristics and postoperative therapy of the patient, and reviewed all of the published cases of conus medullaris glioblastoma...

Leptomeningeal metastases (LM) from solid tumours, lymphoma and leukaemia are characterized by multifocal neurological deficits with a high mortality rate. Early diagnosis and initiation of treatment are essential to kerb neurological deterioration. However, this is not always possible as 25% of cerebrospinal fluid samples produce false-negative results at first cytological examination. The identification of biomarkers that allow stratification of individuals according to risk for developing LM would be a major benefit...

A 52-year-old woman presented with painless vision loss for 3 months. She was in custody for allegedly robbing a bank and had recently been diagnosed with paranoid schizophrenia. She had 20/100 VA OD, a 2+RAPD, and optic atrophy. Extensive diagnostic workup including MRI, Fluorescein Angiography, Infectious Disease Panel, lumbar puncture, and leptomeningeal biopsy were unrevealing. Vision in her right eye declined to NLP and her left eye declined to 20/200 VA. Anti N-methyl-D-aspartate (NMDA) Autoimmune Encephalitis was diagnosed based on CSF serology and clinical suspicion...
