Takotsubo syndrome (TTS) can develop after intense physical or emotional stress and is uncommon in children. We report a 2-year-old girl who developed TTS caused by acute hydrocephalus after posterior fossa tumor resection and required mechanical ventilation and administration of vasopressor/inotropic agents. Her cardiac function gradually recovered over the course of 2 weeks. Hydrocephalus after posterior fossa surgery can cause compression of the medulla oblongata, resulting in solitary nucleus dysfunction and TTS, a potentially life-threatening complication.

Aim: To assess the changes of intracranial pressure waveforms (ICPW) acquired noninvasively in a set of acute hydrocephalus patients prior to and posterior to interventions.
Material And Methods: Patients with clinical and radiological diagnoses of hydrocephalus were evaluated for alterations in ICPW by means of a system that detects cranial micro expansions just before and immediately after interventions. The system quantified the difference between ICPW peaks (P1 and P2), providing the P2/P1 ratio.

The pathogenesis of type I Chiari malformation (CIM) is complex and remains unclear. The theory of posterior cranial fossa incompatibility has gained widespread acceptance in recent years. In the patients with CIM combined with syringomyelia, scoliosis is a common occurrence, with severe cases often leading to complications that necessitate surgical intervention.

Background: This particular case is a world-first with no previous literature reports on patients presenting with both benign acoustic schwannoma and malignant ependymoma.
Case Presentation: A 60-year-old woman with unexplained right-sided hearing loss that had worsened progressively over 4 years, along with intermittent dizziness that had begun 3 years prior. Our preliminary diagnosis included: (1) Right acoustic neuroma; (2) Ependymoma of the fourth ventricle; and (3) Hydrocephalus.

Hydrocephalus is an imprecise term and refers to the imbalance of brain parenchyma and cerebral spinal fluid in the cranial vault. Ventriculomegaly, or enlargement of the ventricular system, is often the more precise term and is therefore preferred. Appropriate imaging and measurement techniques are critical to detect ventriculomegaly and grade its severity.

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.
