May 13, 2022 · Differentiating extradural (EDH) from subdural (SDH) hemorrhage in the head is usually straightforward, but occasionally it can be challenging. SDHs are more common and there are a few distinguishing features which are usually reliable.

Nov 10, 2024 · In almost all cases, extradural hematomas are seen on CT scans of the brain. They are typically bi-convex (or lentiform) in shape, and most frequently beneath the squamous part of the temporal bone. EDHs are hyperdense, somewhat heterogeneous, and …

Jul 31, 2023 · 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. It is confined by the lateral sutures (especially the coronal sutures) where the dura inserts.

Mar 19, 2024 · Extradural hemorrhages (EDH) represent collections of blood in the extradural (epidural) space. The hemorrhage sits between the skull superficially and the dura which overlies the brain parenchyma. The bleed in relation to the dura mater is the key anatomical difference between an extradural and a subdural hemorrhage. As a student, a helpful ...

Jun 20, 2024 · An extradural haematoma (EDH) is an acute haemorrhage between the dura mater and the inner surface of the skull. An EDH can compress local brain structures and raise intracranial pressure. If this pressure continues to rise, cerebellar herniation may occur, leading to brainstem death.

Extradural haematoma (EDH), also known as epidural haematoma, refers to a collection of blood in the extradural space between dura and skull. It is most often due to trauma and commonly associated with a skull fracture (75-95% of cases). EDH is most commonly due to trauma from a direct head injury.

The “classical” EDH occurs from a laceration of the middle meningeal artery after blunt trauma and is biconvex (lens-shaped) in appearance. Hypodense blood within an EDH represents acute unclotted hemorrhage, while hyperdense blood corresponds to acute clotted hemorrhage.

Subjects and methods: The neuroradiologic studies of four patients (CT in four, MR imaging and MR venography in one) were evaluated for EDH shape, size and appearance. Results: EDHs were biconvex in three patients and crescentic in one patient.

Dec 1, 2000 · On this image, the EDH appears to have a biconvex shape. The hemorrhagic cerebrospinal fluid collection (arrows) is predominantly hyperintense. Note the residual deformity of the brain adjacent to the surgical resection bed following removal of the large meningioma.
