Learning objectives
To understand the physiopathology and clinical characteristics of CVT,
PRES and RCVS.
To learn on their clinical and radiological criteria.
To know the particular imaging findings leading to final diagnosis
Background
Cerebral venous thrombosis (CVT),
Posterior reversible encephalopathy syndrome (PRES) and Reversible cerebral vasoconstriction syndrome (RCVS) may have similar clinical presentation,
being non-specific and usually variable,
what makes radiological exams play a crucial role (Fig.3).
Posterior reversible encephalopathy syndrome (PRES):
It is a radiological and clinical entity characterised by a variety of symptoms including headache,
altered mental status,
seizures and visual disturbances,
and by a potentially reversible imaging pattern.
There are a number of factors that favour the development of this syndrome (Fig.4)
Although the pathophysiology...
Conclusion
Radiological exams are of the utmost importance for final diagnosis in these potentially reversible brain syndromes,
whose clinical diagnosis may be challenging.
Primary and secondary imaging findings within an appropriate clinical setting will be the diagnostic key that emergency and general radiologists should recognise (Fig.39).
