This is defined as a collection of blood in the extradural space and can be referred to as an extradural hemorrhage. Signs of intracranial hematomas include headache, vomiting, drowsiness, dizziness, confusion, slurring of speech, and unequal pupil size. Sometimes, this may occur in the spinal column as well. Prognosis and clinical relevance of anisocoria craniotomy latency for epidural hematoma in comatose patients. Pathologic anisocoria reflects an abnormality in the musculature of the iris (iris diseases) or in the parasympathetic or sympathetic pathways that innervate the pupil. It is confined by the lateral sutures (especially the coronal sutures) where the dura inserts. Go to the emergency room or call 911 if emergency symptoms develop after treatment, including breathing difficulties, convulsions/seizures, decreased responsiveness, loss of consciousness, enlarged pupils, and uneven pupil size. An epidural hematoma is defined as a collection of blood in the space between the dura (protective lining that covers the brain) and the skull bone. Idiopathic Intracranial Hypertension, anisocoria Anisocoria Unequal pupil size, which may represent a benign physiologic variant or a manifestation of disease. A FDP is a grave prognostic sign following TBI commonly resulting in long term ophthalmological sequelae however, a favourable outcome is still attainable. An epidural hematoma (EDH) is an extra-axial collection of blood within the potential space between the outer layer of the dura mater and the inner table of the skull. Most patients with bilateral FDP did not survive (88%) however, of those who did survive, none was left in a persistent vegetative state or with any ophthalmological sequelae. Of those patients who survived an FDP, 72% were left with some form of ophthalmological deficit. In 34% of cases CT demonstrated a lateralising condition ipsilateral to the side of the FDP and in 9% cases the FDP was contralateral to the side of the CT abnormality. In patients presenting with a unilateral FDP, the CT-defined condition was most commonly diffuse brain injury (49%) with no obvious lateralising condition.

In approximately three-quarters of cases, some form of road traffic incident was the mechanism of injury. Hematoma inside the skull includes: Epidural hematoma: Blood in the space between the dura mater and the skull. Cohen J, Montero A, Israel Z: Prognosis and clinical relevance of anisocoria- craniotomy latency for epidural hematoma in comatose patients. The objectives of this study were to determine the underlying condition responsible, the natural history of recovery of third nerve palsy and the ultimate clinical outcome in 60 patients admitted to a regional neurosurgical centre with a diagnosis of TBI and unilateral or bilateral fixed, dilated pupils (FDP). Summary Recently we treated 54 patients with acute epidural haematoma, diagnosed by early CT scan and operated on quickly, within 6 hours after trauma. Pupillary abnormalities are commonly seen in patients presenting with severe traumatic brain injury (TBI). It is concluded that even volumes of over 150 cc can be compatible not only with survival but also with very low morbidity, if rapid surgical treatment is performed.
