Meningeal neoplasms associated with cerebral vascular malformations

Surgical Neurology, 1987
Two patients with meningeal neoplasms and nearby vascular anomalies are reported. The lesions were excised and histologically confirmed. One patient had a meningotheliomatous meningioma and an arteriovenous malformation involving the right frontal lobe; the other, a hemangiopericytoma and an arteriovenous malformation in the right parietooccipital ...

Analysis of the inflammatory tumor microenvironment in meningeal neoplasms

Clinical Neuropathology, 2020
Properties of the inflammatory tumor microenvironment are associated with disease subtype, grade, and prognosis in various cancer entities. As immune-modulatory therapies are currently being explored in patients with meningeal neoplasms, we investigated their inflammatory microenvironment (meningiomas and solitary fibrous tumor/hemangiopericytoma (SFT ...

Chromosome abnormalities in meningeal neoplasms: Do they correlate with histology?

Cancer Genetics and Cytogenetics, 1994
Thirty-three meningeal neoplasms were karyotyped, and the results were compared with histologic features. Thirteen neoplasms had no discernible abnormality or sex chromosome loss only; nine had monosomy or structural abnormality involving only chromosome 22; and 11 had other chromosome abnormalities with or without chromosome 22 involvement. Histologic

Computed tomography of disseminated meningeal and ependymal malignant neoplasms

Neurology, 1981
We studied computed tomography (CT) scans of 50 patients with clinical signs and symptoms compatible with disseminated meningeal tumor, all documented by cerebrospinal fluid cytology, surgical biopsy or autopsy. Twenty-three patients also had nuclear scans, and 13 had cerebral angiograms.

Management of Meningeal Neoplasms: Meningiomas and Hemangiopericytomas

Current Treatment Options in Oncology, 2011
Meningiomas are the most frequently diagnosed primary brain tumor accounting for nearly one third of all primary brain and central nervous system tumors reported in the United States. According to the 2007 World Health Organization classification scheme, Grade I meningiomas are benign, Grade II defines atypical lesions, while Grade III meningiomas are ...

Cerebrospinal fluid findings in patients with hematologic neoplasms and meningeal infiltration

Acta Neurologica Belgica, 2020
Neoplastic cell infiltration into the central nervous system (CNS) is a serious complication of hematological neoplasms. Cytomorphology (CM) and flow cytometry (FC) have been used to detect meningeal infiltration. The association between CSF findings with the results of CM and FC is still poorly understood.

Meningeal melanocytosis: a possibly useful treatment for a rare primary brain neoplasm

Journal of Neurology, 2011
Meningeal melanocytosis (MM) is a rare primary leptomeningeal neoplasm of melanotic cells with a slow growing diffuse pattern [1]. It may occur as neurocutaneous melanosis associated with congenital cutaneous nevi, or as isolated MM. MM has a poor prognosis both due to melanocyte malignization and because of progressive meningeal thickening [2–4].

Hypoglycorrhachia (Low Cerebrospinal-Fluid Sugar) in Diffuse Meningeal Neoplasm

New England Journal of Medicine, 1963
IN the difficult and diagnostic problem case of poorly localized Central-nervous-system disease a low concentration or absence of sugar in the spinal fluid may indicate neoplastic infiltration of the leptomeninges. Little attention to this helpful clinical finding has been paid in the medical literature for some time.
