Postoperative hematoma: Postoperative hematomas are a cutaneous condition characterized by a collection of blood below the skin, and result as a complication following surgery.Epidural hematomaSubdural hematomaXYZ file format: The XYZ file format is a chemical file format. There is no formal standard and several variations exist, but a typical XYZ format specifies the molecule geometry by giving the number of atoms with Cartesian coordinates that will be read on the first line, a comment on the second, and the lines of atomic coordinates in the following lines.Cerebral hemorrhageDense artery sign: In medicine, the dense artery sign or hyperdense artery sign is a radiologic sign seen on computer tomography (CT) scans suggestive of early ischemic stroke. In earlier studies of medical imaging in patients with strokes, it was the earliest sign of ischemic stroke in a significant minority of cases.Bifrontal craniotomy: a bifrontal craniotomy is a surgical process which is used to target different tumors or malfunctioning areas of the brain.http://www.Subdural space: The subdural space (or subdural cavity) is a potential space that can be opened by the separation of the arachnoid mater from the dura mater as the result of trauma, pathologic process, or the absence of cerebrospinal fluid as seen in a cadaver. In the cadaver, due to the absence of cerebrospinal fluid in the subarachnoid space, the arachnoid mater falls away from the dura mater.Elias Rudolph Camerarius, Sr.: Elias Rudolph Camerarius, Sr. (1641–1695) was a professor of medicine who notably wrote books on the palpitations of the heart, pleurisy, skull fractures, and the use of medicinal plants.Falx cerebri: The falx cerebri is also known as the cerebral falx, named from its sickle-like form. It is a large, crescent-shaped fold of meningeal layer of dura mater that descends vertically in the longitudinal fissure between the cerebral hemispheres.Altered level of consciousnessLinea alba (abdomen): The linea alba (Latin, white line) is a fibrous structure that runs down the midline of the abdomen in humans and other vertebrates. In humans linea alba runs from the xiphoid process to the pubic symphysis.Closed head injury: Closed Head are a type of traumatic brain injury in which the skull and dura mater remain intact. Closed-head injuries are the leading cause of death in children under 4 years old and the most common cause of physical disability and cognitive impairment in young people.Intracranial hemorrhageHyperintensityClivus (anatomy): The clivus (Latin for "slope") is a part of the cranium at the skull base, a shallow depression behind the dorsum sellæ that slopes obliquely backward. It forms a gradual sloping process at the anterior most portion of the basilar occipital bone at its junction with the sphenoid bone.LaminectomyDrainage system (agriculture): An agricultural drainage system is a system by which the water level on or in the soil is controlled to enhance agricultural crop production.Spontaneous remission: Spontaneous remission, also called spontaneous healing or spontaneous regression, is an unexpected improvement or cure from a disease that appears to be progressing in its severity. These terms are commonly used for unexpected transient or final improvements in cancer.Retroperitoneal hemorrhageEsophageal disease: Esophageal diseases can derive from congenital conditions, or they can be acquired later in life.Suction (medicine): In medicine, devices are sometimes necessary to create suction. Suction may be used to clear the airway of blood, saliva, vomit, or other secretions so that a patient may breathe.Anticoagulant: Anticoagulants are a class of drugs that work to prevent the coagulation (clotting) of blood. Such substances occur naturally in leeches and blood-sucking insects.Spinal decompression: Spinal decompression is the relief of pressure on one or many pinched nerves (neural impingement) of the spinal column.Blunt splenic trauma: Blunt splenic trauma occurs when a significant impact to the spleen from some outside source (i.e.Extravasation (intravenous): Extravasation is the accidental administration of intravenously (IV) infused medications into the extravascular space/tissue around infusion sites, either by leakage (e.g.Orbital apex syndrome: Orbital apex syndrome, also known as Jacod syndrome, is a collection of cranial nerve deficits associated with a mass lesion near the apex of the orbit of the eye. This syndrome is a separate entity from Rochon–Duvigneaud syndrome, which occurs due to a lesion immediately anterior to the orbital apex.Subarachnoid hemorrhageGross examinationArachnoid granulation: Arachnoid granulations (or arachnoid villi) are small protrusions of the arachnoid (the thin second layer covering the brain) through the dura mater (the thick outer layer). They protrude into the venous sinuses of the brain, and allow cerebrospinal fluid (CSF) to exit the sub-arachnoid space and enter the blood stream.Cerebellar stroke syndromeWarfarinStereotactic surgeryExophthalmosNeurosurgery: Neurosurgery (or neurological surgery) is the medical specialty concerned with the prevention, diagnosis, treatment, and rehabilitation of disorders which affect any portion of the nervous system including the brain, spinal cord, peripheral nerves, and extra-cranial cerebrovascular system.AANS – Patient InformationInfectious intracranial aneurysm: An infectious intracranial aneurysm (IIA, also called mycotic aneurysm) is a cerebral aneurysm that is caused by infection of the cerebral arterial wall.Brain injury: A brain injury is any injury occurring in the brain of a living organism. Brain injuries can be classified along several dimensions.International Classification of Headache Disorders: The International Classification of Headache Disorders (ICHD) is a detailed hierarchical classification of all headache-related disorders published by the International Headache Society. It is considered the official classification of headaches by the World Health Organization, and, in 1992, was incorporated into the 10th edition of their International Classification of Diseases (ICD-10).Familial aortic dissection: Familial aortic dissection or FAD refers to the splitting of the wall of the aorta in either the arch, ascending or descending portions. FAD is thought to be passed down as an autosomal dominant disease and once inherited will result in dissection of the aorta, and dissecting aneurysm of the aorta, or rarely aortic or arterial dilation at a young age.
