Neuro_MR_Brain: 17 M, Duchenne's muscular dystrophy, cardiac arrest.

MRI BRAIN WITHOUT CONTRAST:

 

CLINICAL HISTORY: 17 years of age, Male, with Duchenne's muscular dystrophy with cardiac arrest with ROSC following resuscitation. MRI for prognostic management.

 

FINDINGS: 

 

There is diffuse symmetric restricted diffusion with associated T2 signal hyperintensity in the cortex and subcortical white matter with associated T2 signal hyperintensity in the cortex and subcortical white matter of the bilateral cerebral hemispheres posteriorly, bilateral hippocampal formations, bilateral internal capsules, posterior lentiform nuclei, and cerebellum, cerebellar white matter greater than hemispheres. Anterior basal ganglia are swollen and T2 hyperintense without definite diffusion restriction. Findings compatible with hypoxic/ischemic injury. There is mild crowding of the cerebellar tonsils at the foramen magnum, with slight inferior tonsillar displacement measuring up to 5 mm. Basal cisterns are patent. 

There is slight prominence of the lateral ventricles, stable from prior exam. 

There is no mass or hemorrhage. 

No abnormal extracerebral collections are present. 

There are bilateral mastoid effusions, mucosal thickening with layering debris in the left maxillary sinus and sphenoid sinuses, and pooled secretions in the visualized nasopharynx and oropharynx.

 

IMPRESSION: 

 

1.  Findings compatible with diffuse acute hypoxic/ischemic injury, as described above, involving the bilateral cerebral hemispheres posteriorly, hippocampi, basal ganglia, and cerebellum.
