Posterior cranial fossa

craniopharyngiomas may reach enormous size by expanding into the posterior fossa along the retroclival area, which is very unusual finding. A 5-year-old boy presented with headache for 2 month. On the neurological examination, it was normal. Initial magnetic resonance (MR) images revealed a huge, thin-capsuled multi-cystic mass, which extended around brain stem & extending bilaterally along the base of the middle and posterior cranial fossa. Subtotal excision of the cystic wall was done followed by applying

As the maxilla develops in the region posterior to the maxillary tuberosity, the anterior cranial fossa, the palate, and the body of the mandible also has to follow the growth pattern of maxilla and increase in length.21 The mandible follows this growth pattern by remodeling the anterior part of the ramus posteriorly, leaving an offset relationship between the upper and lower arches with the maxilla more forward than the mandible (Class II type relationship).19,21 To keep pace with the anteriorly

the upper spinal cord to the rear of the cerebrum; posterior to the brainstem is the cerebellum. The cerebrum is largest structure in the brain, and it is responsible for motor functions, perception, communication, and memory. It is divided into two hemispheres, and those hemispheres are divided into lobes: the frontal lobe, parietal lobe, occipital lobe, and temporal lobe. The frontal lobe is located in the anterior cranial fossa (frontal cranial depression, in simpler terms). The central

neurophysiology and cranial development. 2. The signs and symptoms of raised intracranial pressure in paediatric neurosurgical cases are age specific. 3. Blood loss due to surgery or tumor bleed into the cavity constitutes a major fraction of total blood volume in the paediatric population. 4. Capnography is the most feasible and safer method to monitor venous air embolism in children. Introduction The majority of tumors (60-70%) in pediatric age group occur in the posterior fossa. The reason behind

direction. ~Superior- above ex. the nose is superior to the mouth ~Inferior- below ex. the abdomen is inferior to the chest ~Anterior- front ex. the face and the arms are in the anterior body surface. ~Posterior- back ex. the spine is posterior to the heart ~Medial- toward the midline ex. the heart is medial to the lungs. ex. the sternum is medial to the ribs

were located mostly over the frontal area of the head and were aggravated by sneezing and coughing. He denied any vertigo, vomiting, lateralising weakness, fever or neck stiffness. On examination, he had a Glasgow Coma Score (GCS) of 15 with no cranial nerve deficits. No cerebellar signs were elicit, he however had grade IV/V

Cranial Nerves The human body is a unique and fascinating entity. There is not much notice taken of the features the human body is capable of. The brain is necessary to perform day-to-day actions, such as the ability to speak, and see amongst us. This brain is made up of simple mater (Pia mater, Arachnoid mater, Dura mater) and the cranial surface to protect the brain. We live our daily lives without acknowledging the importance of this organ, the brain, unless you’re a medical student of

University of Phoenix Material The Skeletal System Exercises After viewing the animation answer these questions. * Exercise 5.1: Coloring Exercise * * Scan completed coloring exercise and submit as a separate document. * * * Exercise 5.2: Appositional Bone Growth * After viewing the animation, answer the following questions: 1. Define appositional bone growth. Formation of new bone on the surface of older bone or cartilage 2. Which cells produce

This type of trauma can lead to upward migration of the condylar head which in turn can result in fracture of the glenoid fossa with condyle dislocation into the middle skull base. Furthermore, this type of dislocation can result in more serious injuries like facial nerve injury, intracranial hematomas, cerebral contusion, leakage of CSF, and impairment to the eighth cranial nerve which is can lead to deafness. • Lateral dislocations: Those are usually commonly accompanied with mandible fractures

from bone and not adjacent structures. The extension of chordomas is primarily posterior, with involvement of the pontine cistern and, occasionally, of the premedullary cistern. On MRI, posterior extension may show as a thumb indenting the pons and/or of the medulla (fig 37-1). Extension can be upward to the sella turcica, displacing the pituitary gland, downward to the nasopharynx or laterally to the middle cranial fossa. Most chordomas demonstrate T1 signal hypointensity and T2 signal
