We treated recurrent hydrocephalus in a previously shunted patient by neuroendoscopic third ventriculostomy. A tear was noted in the septum pellucidum. As the foramen of Monro was found to be occluded, we first fenestrated the floor of the lateral ventricle and then performed third ventriculostomy through the fenestration. A tough membrane believed to be Liliequist's membrane isolated the space immediately beneath floor of the third ventricle from the cistern below. Cerebrospinal fluid pulsation appeared after fenestration of this membrane. These obstructions presumably resulted from congenital and/or inflammatory causes. In cases such as this, successful neuroendoscopic third ventriculostomy presents a challenge to surgical judgment.

Postoperative fever following neuroendoscopic procedures has been well-documented, yet specific differentiation based on the nature and site of the procedure remains lacking. Given the anatomical involvement of the hypothalamus in temperature regulation, we propose that endoscopic third ventriculostomy (ETV) may have a distinct impact on postoperative fever. This study aims to investigate this phenomenon.

The widening of the vestibular dimension of lateral ventricles > 10 mm should be considered a symptom rather than a definitive diagnosis. In fact, fetal ventriculomegaly (VM) is a defect with 'multifaceted' clinical consequences in the child's further neurodevelopment. Isolated fetal ventriculomegaly can cause neurological defects ranging from mild neurodevelopmental delay to severe complications in the form of ongoing palliative care to the death of patients at various developmental periods.

Background: Subdural hematoma (SDH) typically occurs due to traumatic brain injury but can arise as a rare complication of procedures like endoscopic third ventriculostomy (ETV).
Case Presentation: We report an unusual case in a 9-year-old male with previous resection of a fourth-ventricle ependymoma at 2 years of age. Seven years post-surgery, he presented with worsening hydrocephalus and underwent ETV.

Autosomal recessive hypophosphatemic rickets type 2 (ARHR2) is an uncommon hereditary form of rickets characterised by chronic renal phosphate loss and impaired bone mineralisation. This results from compound heterozygous or homozygous pathogenic variants in ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), a key producer of extracellular inorganic pyrophosphate (PPi) and an inhibitor of fibroblast growth factor23 (FGF23). ENPP1 deficiency impacts FGF23 and increases its activity.

Purpose: Arachnoid cysts constitute approximately 1 % of intracranial mass lesions, with quadrigeminal cistern arachnoid cysts being 5-18 % of those. This study presents a series of 31 cases of quadrigeminal cistern arachnoid cysts, constituting the most extensive series reported to date.
Methods: A retrospective analysis was conducted on 31 patients diagnosed with quadrigeminal cistern arachnoid cysts, focusing on clinical presentation, demographics, treatment approaches, and outcomes.
