Diffuse and tiny foci of susceptibility artifact. No restricted diffusion.
Very important small regions of susceptibility artifact (more than a 100) leading to the diagnosis of cerebral fat embolism. Especially with a history of bone infarct which is the etiology of embolism rather than bone fracture as usual. This patient had sickle cell disease with cerebral fat embolism that should evoke bone infarct.
Those lesions are visible in T2*, but better with SWI
Differential are amyloid angiopathy or chronic hypertensive encephalopathy but those hemorrhagic lesions are bigger and fewer.
