purpose: the aim of this study was to investigate the feasibility and effectiveness of endoscopic neurosurgery for patients with third ventricular colloid cysts without ventriculomegaly. methods: seventy-one patients with third ventricular colloid cysts were identified and recruited to this study. eighteen of these patients did not have concomitant hydrocephalus and underwent primary endoscopic...

Real time ultrasound was used to evaluate the anatomy of the fetal brain at different gestational ages. Anatomical correlation with the gross brain was utilized for more accurate identification of the neuroanatomical structures. The normal growth of the ventricular system was studied. Transaxial measurements of the anterior horn (AH) and maximum ventricular length (MVL) and width (MVW) were mad...

Ventriculoperitoneal (VP) shunt proximal tip disconnection is rarely seen as a shunt complication. Shunt dysfunction and hydrocephaly can develop due to this disconnection. Presented here is a case of a disconnection of the ventricular catheter from the shunt valve, which passed between both lateral ventricles by free floating in the brain CT. The patient was operated on for hydrocephaly. The d...

The philosopher Ludwig Wittgenstein chose as his prime exemplar of certainty the fact that the skulls of normal people are filled with neural tissue, not sawdust. In 1980 the British pediatrician John Lorber reported that some normal adults, apparently cured of childhood hydrocephaly, had no more than 5 % of the volume of normal brain tissue. While initially disbelieved, Lorber’s observations h...

Costello syndrome is a rare genetic disorder characterised by growth and mental retardation, macrocephaly, short neck and macroglossia. Cardiac involvement can also occur in Costello syndrome and is presented in the form of hypertrophic cardiomyopathy, tachyarrythmias and valvular dysfunction. Nervous system involvement including ventriculomegaly, hydrocephaly and Chiari type 1 malformation are...

Tectal gliomas are a distinct form of pediatric brainstem tumor usually present with increased intracranial pressure. The tumor may arise from different origins and the most common histologic form is low-grade astrocytoma. We would like to remind and emphasize why it is important to report a tectal glioma in magnetic resonance imaging reports giving two case samples.

Objective: Hydrocephaly is an important factor for neurological development. Microstructural changes of cerebral tissue are detected in diffusion-weighted imaging (DWI), and abnormal brain development can be early. In this study, it was aimed to evaluate fetuses with hydrocephaly by magnetic resonance (MRI). Method: our nineteen twenty-two without any pathology were analyzed retrospectively. Ap...
