Hydatid disease is an endemic zoonotic disease in many areas of the world. Liver, followed by lung, is the most commonly affected organ and involvement of other organs is rare. When brain is involved, lesions are typically supratentorial, and infratentorial localisation is even rarer. We present a 45-year-old woman with hydatid disease located in premedullary location compressing the brain stem...

Primitive neuroectodermal tumor (PNET) is anundifferentiated neoplasm arising from the germinal matrix of the primitive neural tube. It is predominantly an infratentorial tumor of childhood. Adult supratentorial PNETs are less common and extraneural metastasis are extremely unusual. Only five sporadic cases were reported in the international literature.1–6 In this article, we report a rare case...

Superior sagittal sinus pressure, intracranial pressure and arterial pressure were recorded in an experimental series on 10 cats. During drug-induced, severe, acute arterial hypertension and parallel hypercapnia, venous pressure could exceed intracranial pressure in both the supra- and infratentorial compartment. From these data it is concluded that cerebral venous pressure during acute arteria...

Abstract INTRODUCTION Multinodular and vacuolating neuronal tumor (MVNT) is a rare entity that was first recognized by the World Health Organization Classification of Tumors Central Nervous System in 2016. The majority MVNT cases reported were supratentorial location only small subset included infratentorial involvement. In supratentorial, often nidus for seizure surgical resection control. Inf...

Ependymomas are glial neoplasms occurring in any location throughout the central nervous system and supposedly are derived from radial glia cells. Recent data suggest that these tumors may have different biological and clinical behaviors according to their location. Pediatric supratentorial and infratentorial ependymoma (SE and IE) were compared with respect to clinical and radiological paramet...

Santral sinir sisteminin en sık görülen ekstraksiyel tümörü olan menenjiyom %85-90 sıklıkla supratentorial yerleşim göstermekte olup, insidental olarak saptanır. Bu yazımızda, Acil Servis’e senkop ile başvuran 80 yaşındaki bir erkek hastayı sunmaktayız. Yapılan kranial bilgisayarlı tomografi (BT) ve magnetik rezonans görüntüleme (MRG) incelemelerinde posterior fossa orta hatta yerleşim gösteren...
