106 CHAPTER 6 n Head Trauma fibrous membrane that adheres firmly to the internal surface of the skull. At specific sites, the dura splits into two “leaves” that enclose the large venous sinuses, which provide the major venous drainage from the brain. The midline superior sagittal sinus drains into the bilateral transverse and sigmoid sinuses, which are usually larger on the right side. Laceration of these venous sinuses can result in massive hemorrhage. Meningeal arteries lie between the dura and the internal surface of the skull in the epidural space. Overlying skull fractures can lacerate these arteries and cause an epidural hematoma. The most commonly injured meningeal vessel is the middle meningeal artery, which is located over the temporal fossa. An expanding hematoma from arterial injury in this location can lead to rapid deterioration and death. Epidural hematomas can also result from injury to the dural sinuses and from skull fractures, which tend to expand slowly and put less pressure on the underlying brain. However, most epidural hematomas constitute life-threatening emergencies that must be evaluated by a neurosurgeon as soon as possible. Beneath the dura is a second meningeal layer: the thin, transparent arachnoid mater. Because the dura is not attached to the underlying arachnoid membrane, a potential space between these layers exists (the subdural space), into which hemorrhage can occur. In brain injury, bridging veins that travel from the surface of the brain to the venous sinuses within the dura may tear, leading to the formation of a subdural hematoma. The third layer, the pia mater, is firmly attached to the surface of the brain. Cerebrospinal fluid (CSF) fills the space between the watertight arachnoid mater and the pia mater (the subarachnoid space), cushioning the brain and spinal cord. Hemorrhage into this fluid-filled space (subarachnoid hemorrhage) frequently accompanies brain contusion and injuries to major blood vessels at the base of the brain. Brain The brain consists of the cerebrum, brainstem, and cerebellum. The cerebrum is composed of the right and left hemispheres, which are separated by the falx cerebri. The left hemisphere contains the language centers in virtually all right-handed people and in more than 85% of left-handed people. The frontal lobe controls executive function, emotions, motor function, and, on the dominant side, expression of speech (motor speech areas). The parietal lobe directs sensory function and spatial orientation, the temporal lobe regulates certain memory functions, and the occipital lobe is responsible for vision. The brainstem is composed of the midbrain, pons, and medulla. The midbrain and upper pons contain the reticular activating system, which is responsible for the state of alertness. Vital cardiorespiratory centers reside in the medulla, which extends downward to connect with the spinal cord. Even small lesions in the brainstem can be associated with severe neurological deficits. The cerebellum, responsible mainly for coordination and balance, projects posteriorly in the posterior fossa and connects to the spinal cord, brainstem, and cerebral hemispheres. Ventricular System The ventricles are a system of CSF-filled spaces and aqueducts within the brain. CSF is constantly produced within the ventricles and absorbed over the surface of the brain. The presence of blood in the CSF can impair its reabsorption, resulting in increased intracranial pressure. Edema and mass lesions (e.g., hematomas) can cause effacement or shifting of the normally symmetric ventricles, which can readily be identified on brain CT scans. Intracranial Compartments Tough meningeal partitions separate the brain into regions. The tentorium cerebelli divides the intracranial cavity into the supratentorial and infratentorial compartments. The midbrain passes through an opening called the tentorial hiatus or notch. The oculomotor nerve (cranial nerve III) runs along the edge of the tentorium and may become compressed against it during temporal lobe herniation. Parasympathetic fibers that constrict the pupils lie on the surface of the third cranial nerve; compression of these superficial fibers during herniation causes pupillary dilation due to unopposed sympathetic activity, often referred to as a “blown” pupil (n FIGURE 6-3). The part of the brain that usually herniates through the tentorial notch is the medial part of the temporal lobe, known as the uncus (n FIGURE 6-4). Uncal herniation also causes compression of the corticospinal (pyramidal) tract in the midbrain. The motor tract crosses to the opposite side at the foramen magnum, so compression at the level of the midbrain results in weakness of the opposite side of the body (contralateral hemiparesis).
