Learning objectives
"BRAIN ATTACK" is an emergency code entitled to the patients presenting with sudden onset of neurological symptoms,
without history of recent trauma.
Neuroimaging is vital for the diagnosis and subsequent management.
Radiologists should be aware about the imaging features and possible differential diagnosis of various neuroemergencies.
The aimof this poster is thus directed to:
1.
Reviewthe protocols and current state of imaging for evaluation of non- traumatic neuro emergencies,
with emphasis to stroke.
2.
Briefly discuss the possible clinical entities and their pertaining imaging features,...
Background
“Brain attack” is a term used to describe non traumatic acute presentation of neurologic symptoms,
may be secondary to stroke or any other neurological conditions/stroke mimics.
Different imaging techniques and protocols have been developed to aid in determining the cause of these acute neurologic symptoms and to assess brain tissue status.
A standardized imaging approach is proven to be practical and efficient in the prompt diagnosis of Brain attack cases so that urgent and appropriate action may be undertaken.
Important considerations in developing an imaging...
Findings and procedure details
The examiantions were all performed on either 16,64 or 256 slice CT scanner and 1.5T or 3.0 T MRI machines depending on the indication and availability.
Case no 1.( Fig. 7 )
60 yrs old male,
Hypertensive with acute onset left-sided hemiparesis presented to the ER within 1 hour of the symptoms.
Case no 2.(Fig. 8&Fig. 9)
28 yrs old female and 6 wks pregnant,
presentened with severe headache since one week,
two episodes of seizure,
left-sided weakness and loss of consciousness few hours prior...
Conclusion
Stroke represents the majority of non-traumatic neuro emergency,
however,
several other clinical conditions like infection,
inflammation,
demyelination or tumors present with similar clinical features as stroke.
Conventional as well as advanced neuro imaging plays a vital role in timely diagnosis of the disease and subsequent management.
Radiologists should be well knowledged about theimaging features of stroke and non-stroke related diseases presenting with acute neurological symptoms.
