Insights
Colloid cysts of the 3rd ventricle are rare in children but increasingly detected. Early diagnosis and treatment of these benign brain tumors lead to excellent outcomes and symptom resolution.
Area of Science:
- Pediatric Neurosurgery
- Neuropathology
- Neuro-oncology
Background:
- Colloid cysts of the 3rd ventricle are uncommon intracranial tumors, particularly in pediatric populations.
- Despite their rarity, these benign neoplasms offer an excellent prognosis when identified and managed promptly.
Purpose of the Study:
- To analyze the clinical presentation, radiological findings, surgical management, and outcomes of pediatric colloid cysts.
- To evaluate the efficacy of different surgical approaches for treating third ventricular colloid cysts in children.
Main Methods:
- Retrospective analysis of 18 pediatric patients (<18 years) treated for colloid cysts between 1998 and 2003.
- Review of clinical data, neuroimaging (CT), surgical techniques (transcallosal, transcortical, endoscopic), and patient outcomes.
Main Results:
- Headache and vomiting were the most frequent symptoms; papilledema was the most common sign.
- CT scans typically revealed hyperdense, non-enhancing lesions. Transcallosal and endoscopic approaches were most common.
- Most patients achieved asymptomatic status post-operatively, with a mean follow-up of 10.2 months.
Conclusions:
- Colloid cysts, though rare, are being diagnosed more frequently in children.
- Timely recognition and surgical intervention for pediatric colloid cysts yield highly favorable results.
Introduction:
Colloid cysts of the 3rd ventricle are relatively rare intracranial tumours, more so in children. They are benign tumours with excellent prognosis if diagnosed and treated early.
Methods:
A retrospective analysis of 18 cases of colloid cysts in children below 18 years, operated in our institution between September 1998 and November 2003 (5 years) was made. Clinical presentation, radiological findings, surgical approaches and outcome were analysed.
Results:
Age ranged from 7 to 18 years. The male-to-female ratio was 12:6. Headache and vomiting were the most common symptoms. Papilloedema was the most common clinical sign. Pre-operative CT showed a hyperdense non-enhancing lesion in the majority. Twelve patients underwent a transcallosal, 2 a transcortical and 4 an endoscopic approach. Ventriculoperitoneal shunts were done in 5 patients. Postoperatively 2 patients developed epidural haemorrhage which required evacuation. One patient was re-explored for symptomatic residue. A mean follow-up of 10.2 months was available in 9 patients; the majority were asymptomatic.
Conclusion:
Colloid cysts though rare are increasingly detected in children. Their early recognition and treatment give excellent results.
