Neuro_MR_Brain: 2 M, GAS infection and multiorgan failure.

MRI BRAIN, ANGIOGRAM NECK WITHOUT CONTRAST:

 

CLINICAL HISTORY: 2-year-old male with sepsis secondary to Group A streptococcus infection.

 

FINDINGS: 

 

BRAIN: 

 

Parenchyma: Interval decrease in degree of restricted diffusion in the bifrontal periventricular white matter and bilateral cerebellar white matter, with stable associated T2/FLAIR abnormality. Extensive foci of susceptibility in the cerebral white matter, internal capsule, cerebellum, and corpus callosum. Stable extent of disease.

 

Ventricles and extra-axial spaces: Appropriate for age. 

 

Orbits: Normal. 

 

Visualized paranasal sinuses: Fluid in the bilateral maxillary and ethmoid sinuses. 

 

Mastoid air cells: Bilateral mastoid effusions. 

 

Bones: Normal. 

 

Additional comment: None. 

 

INTRACRANIAL ANGIOGRAM: 

 

Anterior circulation: No flow-limiting stenosis or aneurysm. 

 

Posterior circulation: No flow-limiting stenosis or aneurysm.   

 

Additional comment: None.   

 

EXTRACRANIAL ANGIOGRAM:  

 

Motion limited.   

 

Proximal great vessels: No flow-limiting stenosis or dissection.   

 

Cervical vessels: No flow-limiting stenosis or dissection.  

 

Additional comment: None.   

 

PERFUSION: Normal.  

 

 IMPRESSION:   

 

1.  Evolving findings compatible with hemorrhagic leukoencephalitis, not significantly changed in extent.

 

2.  No flow-limiting stenosis, occlusion, or aneurysm in the intracranial and extracranial circulations.
