Magnetic
resonance imaging of arterial stroke mimics: a pictorial review. A 48-year-old woman with intracerebral haemorrhage presenting with left hemiplegia and left homonymous hemianopsia. DWI shows heterogeneous signal abnormalities involving the right lenticular nucleus on b1000 (a), apparent diffusion coefficient (ADC) (b) and fluid-attenuated inversion recovery (FLAIR) (c). The lesion appears as a peripheral hypointensity on T2 with gradient recalled echo weighted imaging (T2-GRE) (d, arrows)

neurological manifestations: correlation of cerebral MRI imaging and lung imaging—Observational study. A 50-year-old male presented with sever continuous headache during COVID infection, expressive aphasia. MRI revealed right occipital well defined intra axial space occupying lesion. a Axial T1 WI showed area of peripheral high SI with central area of iso intense signal intensity. b Axial FLAIR show area of peripheral edema (c) axial T2WI showed area of relative low SI with peripheral edema (d) ADC map and (e) DWI show area of peripheral restriction. Finding correlates with subacute intraparenchymal hematoma. f CT lung showed multifocal GGO and consolidation, very typical COVID abnormalities (CORAD-V)

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. The etiology, epidemiology, treatment and prognosis vary widely depending on the type of hemorrhage, and as such, these are discussed separately.

They are most often broadly divided according to whether they are spontaneous (primary) or due to an underlying lesion (secondary), and then further divided according to etiology and/or location.

  • primary hemorrhages (no underlying lesion)
  • secondary hemorrhages (some other lesion complicated by hemorrhage)
    • vascular malformation
    • cerebral venous thrombosis
    • tumor (primary or secondary)

    • Practical points

    With any intracerebral hemorrhage the following points should be included in a report as they have prognostic implications :

    • location
    • size/volume
      • the ABC/2 formula is widely used, but there may be more accurate formulas (e.g. 2.5ABC/6, SH/2) and analyzes available, some of which, however, may require the addition of specific software to the standard PACS tools
    • shape (irregular vs regular)
    • density (homogeneous vs heterogeneous)
    • presence/absence of substantial surrounding edema that may indicate an underlying tumor
    • presence/absence of intraventricular hemorrhage
    • presence/absence of hydrocephalus
    • when CT angiography is performed, the presence/absence of the CTA spot sign or a vascular malformation
