Gangliogliomas: pathological and clinical correlation
Journal of Neurosurgery, 1981
✓ Fourteen cases of ganglioglioma are analyzed. This tumor can be found anywhere within the central nervous system. The histological appearance is highly variable and does not relate to the biological behavior. The prognosis depends on the location and possible modes of treatment. Overall, the lesion appears to be nonaggressive and consistent with long survival.
Ganglioglioma: a clinical study with long-term follow-up
Surgical Neurology, 1991
Gangliogliomas are uncommon tumors of mixed neoplastic glial and neuronal elements. Because of their low incidence, few large series exist that fully describe the clinical characteristics of patients afflicted with this tumor. We have reviewed the medical records of 20 patients at Duke University Medical Center with histologically proven gangliogliomas. These patients typically presented within the first three decades of life and their most common presenting symptom was seizures. Therapies included surgical resection, either partial or total, radiation therapy, and/or chemotherapy. Long-term follow-up was achieved by chart review and by telephone interview. Patients who underwent gross total resection alone seemed to fare the best when comparing all treatment groups, and we therefore recommend this as the main form of treatment.
Central nervous system gangliogliomas
Journal of Neurosurgery, 1993
The records of 58 patients with gangliogliomas surgically treated between January 1, 1980, and June 30, 1990, were retrospectively reviewed in order to determine long-term survival, event-free survival, and functional outcome resulting after radical resection and to assess the impact of histological grading on outcome. Tumors were located in the cerebral hemisphere in 19 cases, the spinal cord in 30, and the brain stem in nine. Forty-four patients had gross total resection and 14 had radical subtotal resection. Only six patients underwent postoperative irradiation or chemotherapy and, therefore, the outcome was generally related to surgery alone. Of the 58 gangliogliomas, 40 were classified as histological grade I, 16 were grade II, and two were grade III. The median follow-up period was 56 months. There were no operative deaths, and the operative morbidity rate was 5%, 37%, and 33% for cerebral hemisphere, spinal cord, and brain-stem gangliogliomas, respectively. The 5-year actuari...
A case report of rare location of ganglioglioma
Egyptian Journal of Neurosurgery, 2019
Background Gangliogliomas are rare tumors of the central nervous system. They can occur anywhere in the central nervous system but are most commonly located in the temporal lobe and are mainly found in children. Anaplastic ganglioglioma can result from either de novo or transformation of a pre-existing lesion. Case presentation We report a case of de novo anaplastic ganglioglioma in the parieto occipital region, which is a rare location. A 34-year-old lady presented with features of raised intracranial pressure (ICP) with right side hemiparesis. Contrast-enhanced magnetic resonance imaging (CEMRI) of the brain showed well-defined intense heterogenously enhancing solid cystic mass lesion 5.3 × 5.2 cm in the left parieto occipital region with mass effect and midline shift. Intraoperatively, a cystic mass lesion with reddish brown nodule was seen in the left occipital lobe. Complete tumor excision was done. Microscopic and IHC examination was suggestive of anaplastic ganglioglioma. The...
Intracranial ganglioglioma: A rare case report
Gangliogliomas are considered rare tumors which account for 0.4-0.9% of intracranial neoplasms. The peak of its incidence occurs between 10 and 20 years of age. These tumors are composed of glial and ganglion cells and they are relatively low grade neoplasms associated with good prognosis. We report a rare case of intracranial ganglioglioma in a 10 year old boy who underwent surgery and adjuvant radiotherapy.

Ganglioglioma (GG) is a rare mixed glial-neuronal neoplasm accounting for 0.5-5% of all pediatric central nervous system (CNS) tumors. Rarity of this tumor has precluded defining robust treatment guidelines. This retrospective study evaluates the prognostic factors and outcomes of this rare neoplasm. Retrospective analysis of 55 patients with GG was conducted to describe clinical findings, and outcomes. Kaplan-Meier survival and Cox-regression analyses were performed to assess the overall survival (OS) and progression-free survival (PFS). The mean age at diagnosis was 11.8 years (range 1-21 years) with a median follow-up period of 9.5 years. 53 patients (92.7%) had low grade GG and 2 patients had anaplastic GG. 25 patients had tumor progression, whose median PFS was 12 years. Six patients with low grade GG progressed to a higher grade, with median survival of 9.1 month after transformation. The 5 and 10 year PFS were 65 and 57%, respectively. The 5 and 10 year OS was 96 and 86% resp...
Anaplastic ganglioglioma: a report of three cases and review of the literature
Journal of Neuro-Oncology, 2015
Gangliogliomas are rare tumors of the central nervous system that are thought to arise from a glioneuronal precursor and consist of both neuronal and glial elements. Grade III, or anaplastic ganglioglioma (AGG), most commonly affects children and young adults, generally arises in a supratentorial location, is highly epileptogenic, and often results in diffuse local and distant failure within the craniospinal axis. Pathologically, these tumors are graded by the degree of malignancy in their glial portion and radiologic diagnosis is difficult due to the wide variation in its degree of solid and cystic components, contrast uptake, and calcification patterns. This report presents three cases of AGG, with initial treatment including subtotal resection followed by conformal radiotherapy. In the case where the AGG developed in the setting of an existent low-grade astrocytoma, the patient received no chemotherapy. Both of the other de novo cases were managed with adjuvant chemoradiotherapy with temozolomide. Recurrence occurred at 6, 16, and 20 months following therapy. Two of the three patients experienced symptomatic decline at recurrence, but experienced Karnofsky performance status (KPS) improvement after salvage therapy, including the reduction of cranial neuropathy and balance. All patients had a significant reduction in presenting symptoms following salvage therapy. Patients died at 23, 20, and 22 months following initial surgical management, respectively. A review of anaplastic and malignant gangliogliomas is presented in the context of these three cases.
Temporal lobe gangliomas in children
Child's Nervous System, 1986
The ganglioglioma, a mixed tumor with neuronal and glial elements, occurs occasionally in children and young adults. Its incidence, clinical presentation, radiological features, and natural history have not been clearly defined. A review of 111 primary brain tumors treated at our institution shows that 9.0% were gangliogliomas. The temporal lobe was the most common site involved. All patients presented with seizures but were neurologically intact. The CT scan showed a partially calcified mass, frequently isodense or nearly so, with minimal enhancement. Complete removal produced dramatic improvement in seizure control. Radiotherapy and/or chemotherapy are reserved for tumors showing malignant changes in the astrocytic component. Patients with chronic epilepsy, or whose seizures escape control despite anticonvulsants, should be examined with this tumor in mind. Following removal of these low-grade temporal lobe tumors, fewer seizures are seen, and the long-term prognosis is very good.

Object The object of this study was to delineate long-term results of the surgical treatment of pediatric tumors classified as ganglioglioma or gangliocytoma. Methods A cohort of consecutive patients 19 years or younger who had undergone primary resection of CNS tumors during the years 1980-2016 at a single institution were reviewed in this retrospective study of surgical morbidity, mortality, and academic achievement and/or work participation. Gross motor function and activities of daily living were scored using the Barthel Index (BI). Results Patient records for 32 consecutive children and adolescents who had undergone resection for a ganglioglioma were included in this study. Of the 32 patients, 13 were in the first decade at the first surgery, whereas 19 were in the second decade. The male/female ratio was 1.0 (16/16). No patient was lost to follow-up. The tumor was localized to the supratentorial compartment in 26 patients, to the posterior fossa in 5 patients, and to the spinal cord in 1 patient. Only two of the tumors were classified as anaplastic. Of the 30 low-grade tumors, 2 were classified as gangliocytomas, 6 were desmoplastic infantile gangliogliomas, and 22 were ordinary gangliogliomas. The aim of primary surgery was gross-total resection (GTR) and was achieved in 23 patients (71.9%). Altogether, 43 tumor resections were performed. Eight patients underwent a second resection from 1 to 10 years after primary surgery and three of these also had a third resection from 2 to 24 years after initial surgery. The reason for further resection was clinical (seizure control failure/recurrence of epilepsy or progressive neurological deficit) and/or residual tumor progression/recurrence. There was no operative mortality in this series and all 32 patients are alive with follow-up periods from 0.5 to 36 years (median 14 years). Observed 14-year survival is thus 100%. One out of two children with primary anaplastic tumor received local radiotherapy (proton) postoperatively. The other 31 patients did not have any kind of non-surgical adjuvant therapy. Twenty-one out of 26 children with supratentorial tumor had epilepsy as one of their presenting symptoms. Nineteen of these became seizure-free after initial surgery (18 of them after GTR), but 3 patients experienced recurrence of seizures within some years. Functional outcome in terms of ADL, schooling, and work participation was gratifying in most patients. Five patients have persistent hydrocephalus (HC), treated with ventriculoperitoneal (VP) shunts. Conclusion Low-grade gangliogliomas (GGs) can be surgically treated with good long-term results including seizure and tumor control as well as school and working participation.
