Abstract. ... sellar and parasellar lesions, and intracranial hemorrhage. Reversal of anticoagulation must be initiated simultaneously with diagnosis, treatment, and disposition. To appreciate the MR appearance of hemorrhage in the brain, the radiologist needs to be conversant with two paramagnetic phenomena that are seen only in MRI because of unpaired electrons.1 These paramagnetic phenomena are the dipole—dipole interactions, which shorten T1 (like gadolinium), and the magnetic susceptibility effects, which shorten T2 and T2*. 25. An intracerebral hemorrhage, or intraparenchymal cerebral hemorrhage, is a subset of an intracranial hemorrhage and encompasses a number of entities that have in common the acute accumulation of blood within the parenchyma of the brain. 168 (3):803-7, 1988. Radiology residents have a wide range in knowledge, as there is a steep learning curve during this time. Corpus ID: 21268462. In MRI, calcification appears with various signal intensities on conventional spin echo (SE) T1- or T2-weighted images (3-5), which makes it difficult to identify definitively as calcium. Some authors have suggested CNS injury may be compounded by ligation of the internal jugular vein and common carotid artery.

The common causes of ICH are hypertension and aneurysm. These are usually classified by the time frame over which the dominant hemoglobin species is manifest: hyperacute, acute, early subacute, late subacute, and chronic. The etiology, epidemiology, treatment and prognosis vary widely depending on the type of hemorrhage, and as such, these are discussed separately. Intracranial hemorrhage (ie, the pathological accumulation of blood within the cranial vault) may occur within brain parenchyma or the surrounding meningeal spaces. 4. This high-resolution intracranial VW- MRI approach is increasingly used on a clinical basis at many centers to solve diagnostic problems, especially in patients with ischemic stroke or intracranial hemorrhage. Gomori JM et al: Mechanisms responsible for the MR appearance and evolution of intracranial hemorrhage. Brain bleeds go by a few different names: cerebral hemorrhage, intracerebral hemorrhage and intracranial hemorrhage. Bleeding can happen in several different areas: within the brain, beneath the brain membranes or beneath the skull. 2006;26 Suppl 1:S19–41; discussion S42–3. ICH is most commonly caused by hypertension, arteriovenous malformations, or head trauma. Normally, the walls of the cavernous sinus should always be straight or concave.
