Third Ventricular Colloid Cysts in Children

Abstract

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.

Immediate morbidity and mortality associated with transcallosal resection of tumors of the third ventricle

“…Its anatomical components, surgical technique, and outcomes have been described. 2,4,6,[8][9][10][11][12][17][18][19][20][21][22][23][24] The published rates of complications for transcallosal surgery vary widely and range from 6% to 67%, 2,6,[8][9][10][11][13][14][15]18,21,22,[25][26][27][28][29][30] depending on the definition of complications. The morbidity risk we observed was 50%, which falls within the range of previously published rates.…”

Management of pediatric colloid cysts of anterior third ventricle: A review of five cases

“…Most major published series by Mathiesen et al .,[8] Nitta and Symon,[9] Little et al .,[10] Masqood et al . [11] indicate a male predilection. The rate of growth of the cyst is uncertain and whether these cysts eventually become symptomatic is unclear.…”

Occipital Lobe Infarction due to Acute Hydrocephalus Secondary to Third Ventricle Colloid Cyst in a Child

“…[1][2][3][4] Colloid cysts of the third ventricle are rare in children. [5][6][7][8] Obstruction of the foramen of Monro by the colloid cyst in the anterosuperior portion of third ventricle may result in noncommunicating hydrocephalus, which may be complicated by central transtentorial herniation manifesting with brainstem compression and posterior cerebral artery infarction. 5,6,9 We report an 11-year-old boy who presented with acute-onset headache, vomiting, and decreased level of consciousness.…”

Imaging with computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated acute hydrocephalus due to third ventricle colloid cyst with occipital lobe infarction resulting from transtentorial herniation.…”
