Cerebral HemorrhageTraumaRuptured aneurysm HypertensiveHemorrhagic transformation of ischemic infarction (esp. venous)Venous infarctionTumor Vascular malformationsAngioinvasive infectionAmyloid angiopathy

Acute intraparenchymal hematoma

Acute subarachnoid hemorrhage

(and intraventricular)

Subdural vs. Epidural Hematoma

Mixed acute/chronic subdural hematoma

Traumatic Brain Swelling

Effacement of basal cisterns

Traumatic brain swelling with downward herniation

Traumatic brain swelling

Diffuse Axonal (Shear) Injury (DAI)

Diffuse Axonal (Shear) Injury (DAI)

T2*: Increased sensitivity to hemorrhage

Multiple Sclerosis (MS) Imaging

• MRI is the imaging study of choice

• Help establish “dissemination of lesions in time and space”

• Estimate disease burden

• Identify acute (inflammatory) vs. chronic lesions (enhancement = active inflammation)

Tumefactive MS

Infection• Torch(toxoplasmosis, rubella, CMV and HSV

• Meningitis

• Encephalitis

• Cerebritis and parenchymal abscess

• Empyema (subdural/epidural)

• Cysticercosis.

• Hydatid cyst.

• HIV.
