ABSTRACT A rare case of chordoid meningioma in the lateral ventricle observed in an adult is reported. The first clinical manifestation of the disease was a prolonged fever of unknown origin. Abnormalities in the patient's blood chemistry, principally polyclonal hypergammaglobulinemia (immunoglobulin [Ig]G, IgA, and markedly IgE) and an elevated serum level of C-reactive protein, were associated with the disease. The tumor was histologically confirmed to be a chordoid meningioma, and its surgical removal resulted in complete resolution of the patient's symptoms. By combining reverse transcription-polymerase chain reaction and immunohistochemical analysis, it may be shown that cytokine production, including that of interleukin (IL)-6, IL-1beta, and vascular endothelial growth factor, plays a role in the pathogenesis of chordoid meningioma associated with Castleman syndrome.

    ABSTRACT: Meningiomas with prominent inflammation are traditionally classified as "lymphoplasmacyte rich meningioma" (LPM). Both inflammatory and neoplastic meningeal proliferations have recently been linked to IgG4 disease, although a potential association with LPM has not been previously explored. Sixteen meningiomas with inflammatory cells outnumbering tumor cells were further characterized by CD3, CD20, CD68 and/or CD163, CD138, kappa, lambda, IgG and IgG4 immunostains. There were 11 female and 4 male patients, ranging from 22-78 (median 59) years of age. Tumors consisted of 10 WHO grade I, 5 grade II and 1 grade III LPMs. Immunohistochemically, the most numerous cell type was the macrophage in all cases followed by CD3 positive T cells and fewer CD20 positive B cells. Plasma cells ranged from moderate-marked (N=5) to rare (N=7) or absent (N=4). Maximal numbers of IgG4 plasma cells/hpf ranged from 0-32, with only two cases having counts exceeding 10/high power fields. The IgG4/IgG ratio was increased focally in only 2 cases (30% and 31%). Additionally, plasma cells represented only a minor component in most examples, whereas macrophages predominated, suggesting that "inflammation rich meningioma" may be a more accurate term. The inflammatory stimulus for most cases remains to be elucidated.

    ABSTRACT: Background: There is a Th1/Th2 cytokine imbalance and expression of IL-17 in patients with brain tumours. We aimed to compare the levels of IL-17A and IL-6 in sera of glioma, meningioma and schwannoma patients as well as in healthy individuals. Materials and Methods: IL-17A and IL-6 levels were measured in sera of 38 glioma, 24 meningioma and 18 schwannoma patients for comparison with 26 healthy controls by commercial ELISA assays. Results: We observed an increase in the IL-17A in 30% of glioma patients while only 4% and 5.5% of meningioma and schwannoma patients and none of the healthy controls showed elevated IL-17A in their sera (0.29±0.54, 0.03±0.15 and 0.16±0.68 vs. 0.00±0.00pg/ml; p=0.01, p=0.01 and p=0.001, respectively). There was also a significant decrease in the level of IL-6 in glioma patients compared to healthy controls (2.34±4.35 vs. 4.67±4.32pg/ml; p=0.01). There was a direct correlation between the level of IL-17A and age in glioma patients (p=0.005). Glioma patients over 30 years of age had higher IL-17A and lower IL-6 in their sera compared to the young patients. In addition, a non-significant grade-specific inverse trend between IL-17A and IL-6 was observed in glioma patients, where high-grade gliomas had higher IL-17A and lower IL-6. Conclusions: Our data suggest a Th17 mediated inflammatory response in the pathogenesis of glioma. Moreover, tuning of IL-6 and IL-17A inflammatory cytokines occurs during progression of glioma. IL-17A may be a potential biomarker and/or immunotherapeutic target in glioma cases.

    ABSTRACT: AIMS: To discuss the clinical characteristics and prognosis of chordoid meningioma (CM). METHODS AND RESULTS: Tumour samples of CM from 30 patients were re-examined. The postoperative outcomes were analyzed on the basis of clinical observations. The survival probabilities were calculated using the Kaplan-Meier method. Thirty-two operations were performed in 30 cases, including 27 operations for total removal and five operations for subtotal removal. The median follow-up period was 34.0 months. Tumour recurred in five patients, with a median recurrence time of 32.0 months. No systemic manifestations of Castleman's syndrome were found. The majority (80%) of tumours were found in the supratentorial compartments. The MIB-1 labelling index (MIB-1 LI) varied from 1% to 10%. In univariate analyses, the presence of aggressive factors (P = 0.001) and the extent of resection (P = 0.037) were related to progression-free survival (PFS). The MIB-1 LI (P = 0.50) and postoperative radiotherapy (P = 0.62) were not related to PFS. CONCLUSIONS: Chordoid meningioma is a rare subtype of meningioma, and is often found supratentorially. There is an absence of association with Castleman's syndrome. Aggressive factors and the extent of resection are helpful in predicting recurrence. It might be more pertinent to downgrade CM to grade I, unless it shows aggressive factors.
