Background: Ganglioglioma (GG) of the third ventricle is rare. Surgical excision of tumors in this location is associated with high morbidity due to nearby eloquent brain centers. Alternative treatments, when available, should be considered to reduce risks of surgical treatment.
Case Description: We present the case of a 21-year-old female diagnosed with a BRAF V600E mutated GG of the third ventricle. After an endoscopic biopsy and insertion of a ventriculoperitoneal shunt, the patient was started on the inhibitor dabrafenib, as an alternative to surgery or radiation. Nearly 2 years after starting dabrafenib, her tumor appearance on serial magnetic resonance imaging is stable, and she has maintained a good quality of life with no new neurological symptoms.
Conclusion: The disease control thus far suggests targeted medical therapy of GG of the third ventricle with inhibitors may have efficacy and should be a considered treatment modality.

Introduction: Endoscopic Third Ventriculostomy (ETV) is a well-established treatment for pediatric hydrocephalus, particularly in cases of aqueductal stenosis. The ETV Success Score (ETVSS) is a predictive tool widely used to estimate the likelihood of ETV success based on factors like age. Its accuracy, especially in infants under 3 months, is still debated.

Aim: Percutaneous vertebroplasty is generally considered a safe procedure, however, cases of cardioembolism and cardiac perforation have been reported.
Case Presentation: A 69-year-old woman was referred to our emergency department after an outpatient echocardiogram revealed a "thrombus-like" formation involving the right heart. Two weeks before she had undergone percutaneous vertebroplasty of the third to fifth lumbar vertebrae due to osteoporotic fractures.

Endoscopic third ventriculostomy with or without choroid plexus cauterization for preventing shunt dependence in pediatric hydrocephalus: preliminary results of a prospective clinical case series in a lower-middle-income country (Egypt).
Childs Nerv Syst
December 2024
Department of Neurosurgery, Boston Childrens Hospital, Harvard Medical School, Boston, MA, USA.
Purpose: Pediatric hydrocephalus imposes a significant clinical and financial burden in developing countries. Traditional treatment by ventricular shunting in this setting suffers a high rate of shunt infection and malfunction. This study aims at assessing the efficacy and safety of endoscopic third ventriculostomy (ETV), either alone or combined with choroid plexus cauterization (CPC), for preventing shunt dependence in pediatric hydrocephalus within a healthcare setting of a tertiary hospital in Egypt.
