The Skull, Meninges and Blood Supply By Dr Sharon Truter
Pathology: Base of Skull/Basilar Fracture Typically involving the temporal bone, occipital bone, sphenoid bone, and/orethmoid bone. Also anterior bones. Such fractures can cause tears in the meninges, with resultant leakage of the cerebrospinal fluid (CSF). CSF may dribble out through a perforated eardrum (CSF otorrhea), into the nasopharynx (causing a salty taste), or drip from the nose (CSF rhinorrhea) Battles Sign Bilateral Raccoon eyes
Base of Skull Fracture Battle s sign (William Henry Battle) Bilateral raccoon eyes
Pathology: Meningitis Inflammation of meninges (-itis = inflammation) Caused by viruses, bacteria or other micro organisms. Common symptoms: Headache Neck stiffness Fever Confusion or altered consciousness, Vomiting Photophobia and phonophobia A lumbar puncture diagnoses. Meningitis can lead to serious long-term consequences such as: deafness, epilepsy, hydrocephalus and cognitive deficits
Pathology: Epidural and Subdural Haematoma
Pathology: Subarachnoid haemorrhage Scalp Haematoma
Scalp Haemtoma Occur on the outside of the skull between the bone and the skin of the scalp. There are numerous layers to the scalp and the hematoma may be located in any of those layers. While a scalp hematoma cannot press on the brain and cause symptoms, it is a signal that a head injury has occurred and there may also be underlying brain injury. This is especially true for neonates and infants.
Arteries and Veins Arteries Veins
Cerebral Arteries Anterior Cerebral Artery Posterior Cerebral Artery Middle Cerebral Artery
Blood Flow ACA = Anterior cerebral artery MCA = Middle Cerebral Artery PCA = Posterior Cerebral Artery
Circle of Willis Made up of: Anterior cerebral artery (left and right). Anterior communicating artery. Internal carotid artery (left and right). Posterior cerebral artery (left and right). Posterior communicating artery (left and right).
Circle of Willis The basilar artery and middle cerebral arteries, supplying the brain, are not considered part of the circle. If one part of the circle becomes blocked or narrowed (stenosed) or one of the arteries supplying the circle is blocked or narrowed, blood flow from the other blood vessels can often preserve the cerebral perfusion well enough to avoid the symptoms of ischemia.
Pathology of the Arteries and Veins Cerebral ischemia (stroke). Thrombosis: blood clot in vessel. Embolism: blood clot from larger vessel forced into a smaller one. Reduction in blood flow: cerebral arteriosclerosis. Transient ischemia. Cerebral haemorrhage (bleeding). Angioma: Congenital collections of abnormal vessels that divert normal blood flow. Aneurisms: Vascular dilations from localised defects in the elasticity of the vessels.
Pathology: Stroke A sudden appearance of neurological symptoms as a result of severe interruption of blood flow.
Angiography A substance that absorbs X-rays is injected into the blood stream.
Pathology: Headaches Headaches Pain caused by pressure, displacement or inflammation. Pain sensitive structures: dura mater, large arteries of the brain, branches of some of the cranial nerves (5th, 9th & 10th). Migraine (Greek: hemi = half; kranion = skull) Aura: constriction of one or more cerebral arteries has produced ischemia of the occipital cortex. Actual headache: begins as the vasoconstriction reverses and vasodilation takes place. Types: Classic. Common. Cluster headache. Hemiplegic migraine (loss of movement of limbs). Opthalmologic migraine (loss of movement of eyes).
