Chang9, Mitchel Berger9, Andrew W. Bollen1, Arie Perry1,9, Tarik Tihan1 and David A. Solomon1,3* Abstract Ganglioglioma is the most common epilepsy-associated neoplasm that accounts for approximately 2% of all primary brain tumors. While a subset of gangliogliomas are known to harbor the activating p.V600E mutation in the BRAF oncogene, the genetic alterations responsible for the remainder are largely unknown, as is the spectrum of any additional cooperating gene mutations or copy number alterations. We performed targeted next-generation sequencing that provides comprehensive assessment of mutations, gene fusions, and copy number alterations on a cohort of 40 gangliogliomas. Thirty-six harbored mutations predicted to activate the MAP kinase signaling pathway, including 18 with BRAF p.V600E mutation, 5 with variant BRAF mutation (including 4 cases with novel in-frame insertions at p.R506 in the β3-αC loop of the kinase domain), 4 with BRAF fusion, 2 with KRAS mutation, 1 with RAF1 fusion, 1 with biallelic NF1 mutation, and 5 with FGFR1/2 alterations. Three gangliogliomas with BRAF p.V600E mutation had concurrent CDKN2A homozygous deletion and one additionally harbored a subclonal mutation in PTEN. -
Pediatric and Adolescent Oligodendrogliomas
Pediatric and Adolescent Oligodendrogliomas Harold Tice, 1 Patrick D. Barnes, 1 Liliana Goumnerova,2 R. Michael Scott,2 and Nancy J . Tarbell3 PURPOSE: To review the clinical and imaging findings in pediatric and adolescent intracranial pure oligodendrogliomas. METHODS: The clinical, CT, and MR data in 39 surgically proved pure oligodendrogliomas were retrospectively reviewed. RESULTS: The frontal or temporal lobes were involved in 32 (82%) cases. Seventy percent of the tumors were hypodense on CT, three-fourths were hypointense on T1-weighted images, and all were hyperintense on spin-density and T2- weighted images. Fewer than 40% of the lesions demonstrated calcification, and nearly 60% had well-defined margins. Mass effect was seen in fewer than half of the cases, and edema could be separately identified in only one case. Tumor enhancement was seen in fewer than 25%. In 39 cases after partial (3), subtotal (16), or total (20) resection, follow-up studies demonstrated stability over a mean period of 5 years. CONCLUSION: The findings in this pediatric series of pure oligodendrogliomas (without mixed cell elements) differ from previous adult series in that ca lcifi cation, contrast enhancement, and edema are seen less frequently. In addition, very slow or no growth is often characteristic, and these patients have an excellent prognosis with su rgical resection.

The tumour, in a child aged 5 years with an enlarged head since infancy, presented as a large solid intra-cerebral mass. Histological examination showed four types of cells; (i) the stroma, forming the bulk of the tumour, was astrocytomatous; (ii) lobules of ill defined cells bearing small circular nuclei, representing immature neuroblasts; (iii) the same or other lobules containing neurons in various stages of development; and (iv) dense clusters of cells with hyperchromatic nuclei attempting rosettes, representing an overtly malignant neuro- blastoma.

Dysembryoplastic Neuroepithelial Tumor Originally Diagnosed As
ARTICLE Dysembryoplastic neuroepithelial tumor originally diagnosed as astrocytoma and oligodendroglioma Tumor neuroepitelial disembrioplásico diagnosticado originalmente como astrocitoma ou oligodendroglioma Diego Cassol Dozza1, Flávio Freinkel Rodrigues2, Leila Chimelli3 ABSTRACT Dysembryoplastic neuroepithelial tumor (DNT), described in 1988 and introduced in the WHO classification in 1993, affects predominantly children or young adults causing intractable complex partial seizures. Since it is benign and treated with surgical resection, its recognition is important. It has similarities with low-grade gliomas and gangliogliomas, which may recur and become malignant. Objectives: To investigate whether DNT was previously diagnosed as astrocytoma, oligodendroglioma, or ganglioglioma and to determine its frequency in a series of low-grade glial/glio-neuronal tumors. Methods: Clinical, radiological, and histological aspects of 58 tumors operated from 1978 to 2008, classified as astrocytomas (32, including 8 pilocytic), oligodendrogliomas (12), gangliogliomas (7), and DNT (7), were reviewed.Results: Four new DNT, one operated before 1993, previously classified as astrocytoma (3) and oligodendroglioma (1), were identified. One DNT diagnosed in 2002 was classified once more as angiocentric glioma. Therefore, 10 DNT (17.2%) were identified. Conclusions: Clinical-radiological and histopathological correlations have contributed to diagnose the DNT. Key words: dysembryoplastic neuroepithelial tumor, low-grade gliomas, epilepsy.
