Insights
Six children with tuberous sclerosis (TS) and intraventricular tumors underwent successful surgical removal. Early diagnosis and regular monitoring via CT scans are crucial for managing these subependymal giant cell astrocytomas.
Area of Science:
- Pediatric Neurosurgery
- Neurology
- Oncology
Background:
- Tuberous sclerosis (TS) is a genetic disorder that can lead to the development of tumors, particularly intraventricular tumors.
- Intraventricular tumors in TS patients are often subependymal giant cell astrocytomas (SGCA).
- These tumors can cause significant neurological complications if not managed.
Purpose of the Study:
- To describe the diagnosis and surgical treatment of intraventricular tumors in children with tuberous sclerosis.
- To analyze the growth pattern of subependymal giant cell astrocytomas in TS patients.
- To recommend follow-up protocols for TS patients at risk of developing these tumors.
Main Methods:
- Retrospective analysis of six pediatric patients diagnosed with TS and intraventricular tumors between 1987 and 1992.
- Diagnosis confirmed by Gomez criteria, CT, and MRI.
- Surgical tumor removal via frontal transcortical approach.
- Histopathological examination to identify SGCA.
Main Results:
- All six patients underwent successful total tumor removal with no postoperative complications.
- Histopathology confirmed subependymal giant cell astrocytoma in all cases.
- Observed growth patterns of SGCA in TS patients documented via sequential CT scans.
Conclusions:
- Surgical resection is an effective treatment for intraventricular SGCA in children with TS.
- Periodic CT scanning (at least every 2 years) is recommended for TS patients for early detection and management.
- Understanding the growth patterns of SGCA aids in timely surgical intervention.
Abstract:
Six children with intraventricular tumors associated with tuberous sclerosis (TS) were treated at the Children's Health Center, Department of Pediatric Neurosurgery, in the period 1987-1992. The age of the patients ranged from 7 to 15 years. TS was diagnosed according to Gomez diagnostic criteria. Computer tomography (CT) and magnetic resonance imaging showed intraventricular tumors associated with ventricular enlargement and multiple subependymal nodules commonly observed in cases of TS. All tumors were removed totally through frontal transcortical approach, with uneventful postoperative recovery. One patient, with two parallel tumors in the two frontal horns, underwent one-stage surgery with successful total removal. Histopathological examination in all cases showed subependymal giant cell astrocytoma (SGCA). The growth pattern of SGCA associated with TS, documented by sequential CT scans over several years, is described. The diagnosis and surgical treatment of the tumor are discussed, and periodic CT scanning, at least every 2 years, is recommended for patients with TS.
