Acute CT Brain - Extra-axial haemorrhage - Radiology Masterclass Intracranial bleeding is either intra-axial (in the brain) or extra-axial (outside the brain) There are three types of extra-axial haemorrhage: extradural haematoma, subdural haematoma, and subarachnoid haemorrhage
How to recognize extra-axial hemorrhages on brain computed tomogr . . . One visual clue on CT that can help determine whether the patient has a chronic subdural hematoma, or a wide subarachnoid space is the shape and location of the cortical veins A subdural fluid collection will displace the cortical veins away from the inner table of the skull
Extra-Axial Hematomas | Neupsy Key The entities to be discussed include acute epidural hematoma (EDH), acute subdural hematoma (aSDH), subdural hygroma, subacute subdural hematoma (sSDH), and chronic subdural hematoma (cSDH) Special considerations of posterior fossa (PF) lesions and child abuse are also presented
Non-traumatic Intracranial Hemorrhage - The Radiology Assistant Hypertensive hemorrhage typically occurs in elderly patients and is usually in a central location This differentiates hypertensive bleeding from hemorrhage in patients with cerebral amyloid angiopathy (CAA) which are more peripheral in location, although overlap can occur
learningneuroradiology. com - Intracranial Hemorrhage The most common cause of subarachnoid hemorrhage is trauma with blood products seen in a peripheral sulcal distribution However, when subarachnoid hemorrhage is seen filling the basilar
Extra Axial Hematoma: Guide, Symptoms Causes A CT scan or MRI of the brain is crucial for identifying the presence, size, and location of the extra axial hematoma to determine the best course of treatment
1 Brain and Extra-axial Lesions(Table 1. 9 – Table 1. 10) - Radiology Key Axial image shows a subdural hematoma on the left with high attenuation and mass effect with subfalcine herniation rightward Also seen is a subarachnoid hemorrhage anteriorly and blood in the posterior portions of the lateral ventricles from head trauma
