Carotid pseudoaneurysms of petrous localization are rare. They are mostly due to trauma, tumoral or infectious diseases, or a result of iatrogenic complications after skull base surgery. Symptoms such as facial paralysis are exceptional and have rarely been described in the literature until now. We report the case of a 64-year-old woman, who developed left peripheral facial paralysis induced by...

Accurate identification of acute hemorrhage is a critical step in planning appropriate therapy. The correct characterization of underlying pathology, such as neoplasia, vascular malformation, or infarction, is equally important for conclusive diagnosis. Computer-aided diagnosis (CAD) systems have been the focus of several research endeavors and it is solely based on the idea of analyzing images...

We describe the case of a nine-day-old female Holstein calf which had cheiloschisis, a moderate dome-shaped head, ataxia and opisthotonus since birth. No significant findings except the dome-shaped head were observed on survey radiography of the skull. Computed tomography (CT) images showed bilateral lateral ventriculomegaly, cerebellar hypoplasia and a cyst-like lesion communicating with the r...

thought to be variations of a single gene disorder turn out to be genetically diverse with different genetic and!/or clinical implications for a family. The twenty-eight articles in this book discuss as precisely as is now possible the penetrance and variable expression in several kinds of malformation syndromes. The broad, well-organized range of subjects includes syndromes involving primarily...

The Klippel-Feil syndrome is a congenital malformation of the skull flap involving complex cervical vertebrae and organs, characterized by a classic triad: short neck, limitation of movement of the head due to cervical spine fusion and low hairline in occipital region. It results from an error in the axial skeleton segmentation of the embryo; its incidence is estimated at 1/40,000-42,000 births...

While developing a method for doing perinatal necropsies some 4,000 necropsies ago, we were disturbed about the contamination of the cerebrospinal fluid with blood whilst opening the skull, and a technique was devised of opening the dura over the base of the skull, sampling the cerebrospinal fluid and inspecting the foramenmagnum frombelow before the skull was touched. That method (Emery, 1960)...

Lion (Panthera leo) populations have dramatically decreased worldwide with a surviving population estimated at 32,000 across the African savannah. Lions have been kept in captivity for centuries and, although they reproduce well, high rates of stillbirths as well as morbidity and mortality of neonate and young lions are reported. Many of these cases are associated with bone malformations, inclu...

A cranial osteoma typically develops in the accessory nasal sinus of young and middle aged women.1–3 In contrast, a giant osteoma (≥ 10 cm diameter) preferentially grows on the parietal skull1 as a single lesion. A 24yearold woman developed a series of lumps on the scalp of the right frontal to parietal skull since her teens. From the age of 20, the cephalic lump gradually grew (Figure 1). No h...

Introduction. Acrania is a very rare lethal congenital malformation characterized by an absence of the cranial vault with developed cerebral hemispheres. It sometimes confused anencephaly in which both forebrain and neurocranium are not developed. Although these two conditions principally differ their morphology pathogenesis, acrania may be precursor development through process known as Acrania...

The Arnold-Chiari malformation is a congenital abnormality of CNS, characterized by downward displacement the parts of the cerebellum, fourth ventricle, pons and medulla oblongata into the spinal canal. This malformation is one of causative factor of death in neonates and infants. A thorough understanding of the direct and indirect sonographic findings is necessary for diagnosis of Chiari II ma...
