Brain hamartomas and tumors associated with tuberous sclerosis

Area of Science:

• Neurology
• Oncology
• Pediatrics

Background:

• Tuberous sclerosis is a genetic disorder that can cause benign tumors (hamartomas) to grow in various organs, including the brain.
• Ventricular tumors in tuberous sclerosis predominantly affect children and young adults and are usually histologically benign.
• These tumors can present acutely, leading to increased intracranial pressure and significant morbidity or mortality.

Purpose of the Study:

• To review the characteristics, clinical presentation, and prognosis of ventricular tumors associated with tuberous sclerosis.
• To emphasize the benign nature of these tumors and the effectiveness of surgical intervention.

Main Methods:

• Review of existing literature on tuberous sclerosis and associated ventricular tumors.
• Analysis of clinical presentations, diagnostic challenges, and treatment outcomes.

Main Results:

• Ventricular tumors in tuberous sclerosis are predominantly hamartomas or benign neoplasms.
• No definitive gross or histological differences are consistently found between "candle gutterings" and "tumors".
• Acute presentation with increased intracranial pressure is a significant risk, but surgical removal or decompression leads to a favorable prognosis.

Conclusions:

• Ventricular tumors in tuberous sclerosis are typically benign with a good prognosis after surgical management.
• Malignant transformation of these lesions is exceptionally uncommon.
• Prompt diagnosis and intervention are crucial for managing acute presentations and improving patient outcomes.
