Neurenteric cysts (NC) are rare, endodermal-derived intracranial lesions, commonly located anteriorly in the posterior cranial fossa. We describe a rare case of a giant posterior fossa NC (6.5 × 5.9 × 4.3cm) located dorsal to the brain stem in a Chinese woman with a 1 week history of cerebellar symptoms. To our knowledge, this is the largest documented cyst of this type and the third dorsally l...

OBJECTIVES/HYPOTHESIS Examine a protective crumple zone effect of paranasal sinuses and nasal cavity on skull base fractures. STUDY DESIGN Randomized-control, cadaveric study. METHODS In the experimental group (n = 4), the nasal cavity and bilateral sinuses of cadavers were obliterated with bone cement, whereas the control group (n = 4) had native sinus architecture. Increasing frontal, gla...

BACKGROUND Bony wall damages in the region of the middle and posterior cranial fossa are usually observed in cases of chronic otitis media. These defects can also be congenital, post-traumatic, iatrogenic or due to tumors. They can potentially lead to the development of intracranial complications. MATERIAL/METHODS We analyzed patients who were diagnosed as having bony wall damage in the regio...

www.pedijatrijadanas.com Objective The aim of this study was to analyse the clinico-pathological characteristics, treatment, complications and outcome in patients with low grade astrocytomas (grade I and II). Patients and Methods This study was a retrospective analysis of 50 consecutive patients younger than 15 years who were hospitalized for surgical treatment of posterior cranial fossa tumour...

A 20-year-old woman suffered gradual progression of right pulsatile exophthalmos and slight headache. Computed tomography (CT) demonstrated outward and downward displacement of the right globe and an arachnoid cyst in the right middle cranial fossa associated with thinned and anterior protrusion of a bony orbit. Microscopic cystocisternotomy was performed and the cerebrospinal fluid (CSF) insid...

Involvement of the lower cranial nerves as false localizing signs of intracranial tumour is very rare. A laterally placed posterior fossa meningioma gave rise to contralateral cerebellar ataxia and palsies of the fifth, ninth, and tenth cranial nerves.

Dandy-Walker malformation (DWM) is a congenital abnormality of the posterior cranial fossa with reported incidence of 1:25,000 to 1:35,000 live births [1,2]. The classic clinical trials of the DWM are absence of cerebellar vermis, cystic dilatation of the fourth ventricle, and the enlargement of posterior cranial fossa [3]. In approximately 80% of diagnosed DWM cases, the syndrome is accompanie...
