Fibrous dysplasia (FD) is a relatively uncommon disorder that affects primarily the cranial region; its occurrence in the cranial base in combination with hindbrain herniation and aneurysmal bone cyst (ABC) constitutes an extremely rare condition. We report a case of polyostotic fibrous dysplasia with progressive occipital, temporal, and clival involvement. Clinical findings and differential di...

We reported a rare case of hemorrhagic epidermoid cyst located in the anterior cranial fossa. A 66-year-old female presented with progressive nausea and vomiting for one month. Computed tomography revealed a mixed high and low density mass in the right lateral frontal basal region, with a few stippled calcifications at its inferior wall. Magnetic resonance imaging showed that the lesion was lar...

BACKGROUND Computed Tomography (CT) has become a widely used supplement to medico legal autopsies at several forensic institutes. Amongst other things, it has proven to be very valuable in visualising fractures of the cranium. Also CT scan data are being used to create head models for biomechanical trauma analysis by Finite Element Analysis. If CT scan data are to be used for creating individua...

OBJECTIVE Chiari malformations are regarded as a pathological continuum of hindbrain maldevelopments characterized by downward herniation of the cerebellar tonsils. The Chiari I malformation (CMI) is defined as tonsillar herniation of at least 3 to 5 mm below the foramen magnum. Increased detection of CMI has emphasized the need for more information regarding the clinical features of the disord...

Because of its vulnerable location, the frontal sinus may be involved in several types of maxillofacial trauma. This involvement may cause fractures of the anterior and/or posterior walls of the sinus,1 lodgment of foreign bodies in the sinus,2 and anterior cranial fossa dural tears, which may result in cerebrospinal fluid (CSF) rhinorrhea, meningitis, aerocele, and other intracranial complicat...

BACKGROUND The knowledge of the location and morphometric of the lateral venous sinus (transverse and sigmoid), and their relationship with the asterion and other surface anatomical landmarks, it is imperative for posterolateral approaches to the posterior cranial fossa to avoid vascular structures injury and surgical complications. OBJECTIVE Determine an anatomical area security for a drill ...

Rare Complication of Orthognathic Surgery: Intrusion Mandibular Condyle into the Middle Cranial Fossa

Cerebellum is known to play an important role in coordination and motor functions. In some resent studies it is also considered to be involved in modulation of mood, cognition and psychiatric disorders. Dandy Walker Malformation is a congenital malformation that is characterized by hypoplasia or aplasia of the cerebellar vermis, cystic dilatation of the fourth ventricle and enlargement of the p...

INTRODUCTION Medulloblastoma is one of the most common pediatric brain malignancies. The usual presenting clinical features are related to posterior fossa syndrome or/and hydrocephalus. Cauda equina syndrome is a very rare presentation for this disease. CASE PRESENTATION We describe the case of a three-year-old boy with cauda equina syndrome as the initial presenting clinical feature for medu...
