The conventional MR imaging appearance of gangliogliomas is often variable and nonspecific. Conventional MR images, relative cerebral blood volume (rCBV) and vascular permeability (K(trans)) measurements were reviewed in 20 patients with pathologically proven grade 1 and 2 gangliogliomas (n = 20)
Amino acid uptake is higher in high-grade than in low-grade gliomas; this is the rationale for using radioactively labelled amino acids for the non-invasive grading of brain neoplasms. We present a 14-year-old boy with a low-grade desmoplastic infantile ganglioglioma (DIG) that exhibited marked
Desmoplastic ganglioglioma is a rare, markedly desmoplastic variant of ganglioglioma that usually presents in the first year of life. It is a mixed glial and neuronal cerebral tumor. A few cases of desmoplastic ganglioglioma have been reported in non-infantile patients. We report a case of
Thirteen cases of pathologically proved intracranial gangliogliomas were reviewed in order to define the characteristic computed tomography (CT) and magnetic resonance image (MRI)-features. All patients were evaluated with CT and four of them were studied by MRI. Six tumors were cystic dominant
OBJECTIVE
The purpose of this study was to compare MR imaging features of gangliogliomas in children less than 10 years old with those seen in patients at least 10 years old.
METHODS
Our study population consisted of 15 female patients and 10 male patients with a mean age of 20 years. The early
OBJECTIVE
To date there have been only scattered case reports comparing the nuclear medicine characteristics of gangliogliomas with their histologic grade. We sought to determine the relative usefulness of nuclear medicine scanning, CT, and MR imaging in predicting the histologic grade of these
Gangliogliomas are rare tumors of the central nervous system, usually containing neoplastic ganglion cells and astrocytic components. Few cases of ganglioglioma containing only oligodendrocytic tissue have been reported to date. We present a case of a 40-year-old woman with ganglioglioma consisting
OBJECTIVE
Dysembryoplastic neuroepithelial tumors (DNET) and gangliogliomas (GG) are generally associated with epilepsy in young patients. Presurgical work-up and postsurgical results vary from center to center. Seizures are commonly focal with secondary generalization, and surgical treatment is
Three patients (ages 5, 16 and 21 years) with chronic, refractory, partial epilepsy and temporal lobe ganglioglioma were evaluated for surgical treatment. Noncontrast CT revealed a low attenuation, cystic temporal lesion in 2 patients. One neoplasm demonstrated focal calcification and temporal
OBJECTIVE Tumor-related edema of the optic tract (EOT) corresponds to a preferential posterior distribution of peritumoral edema along the white matter tract of the visual system. To date, the consequences of EOT have never been evaluated specifically in the pediatric population. In this study, the
OBJECTIVE
To review the imaging features of infratentorial gangliogliomas (GGs) and compare between Infratentorial GGs located within the cerebellum and brainstem.
METHODS
The cases of 24 patients with histologically-confirmed infratentorial GGs were reviewed retrospectively. These subjects' cases
We present three cases of desmoplastic infantile ganglioglioma in patients admitted to our institution in the past 8 years. CT and MR findings are discussed. Typically, these lesions are located in the frontal and parietal lobes, appearing as cystic tumors with a solid cortical component within the
OBJECTIVE
Our purpose was to describe the MR imaging features in a series of spinal intramedullary gangliogliomas and to compare these findings with the MR features of intramedullary astrocytomas and ependymomas.
METHODS
A retrospective analysis was performed of 76 MR examinations in 27 patients
The differentiation of infratentorial ganglioglioma and pilocytic astrocytoma may be therapeutically relevant, which is sometimes challenging to both pathologists and neuroradiologists.To evaluate the conventional magnetic resonance imaging (MRI), A 57-year-old man suffered a generalized seizure. Brain MRI showed a Gadolinium (Gd) enhanced lesion with massive edema in the left frontal lobe. He received in a brain biopsy a diagnosis of ganglioglioma, probable. After two weeks from the biopsy, brain MRI showed spontaneous remmision of the
