[Reversible segmental cerebral vasoconstriction: the value of duplex transcranial Doppler in its diagnosis and follow up].
BACKGROUND
Reversible segmental cerebral vasoconstriction, also known as Call Fleming syndrome, is a clinical entity that consists of segmental vasoconstriction of the arteries in the brain, which can course with focal neurological deficits and which is characteristically reversible. Diagnosis and follow up of reversible segmental cerebral vasoconstriction is performed using cerebral arteriography, but no previous evaluation has been conducted of the role that duplex transcranial Doppler can play in this syndrome.


METHODS
Here we describe the case of a 57 year old female patient who began suffering from sudden bouts of headaches with no other accompanying clinical features. After ruling out the possibility of a subarachnoid haemorrhage by means of a spinal tap, a suspicion diagnosis of reversible segmental cerebral vasoconstriction was made through duplex transcranial Doppler and this was later confirmed by arteriography, which revealed a segmental stenosis in the upper branch of the left middle cerebral artery. Following treatment with nimodipine, the patient presented a clear clinical improvement and the reversibility of the cerebral vasoconstriction was confirmed by duplex transcranial Doppler.


CONCLUSIONS
Contrast enhanced duplex transcranial Doppler would enable us to obtain an early diagnostic approximation in patients in whom segmental vasoconstriction is suspected; it could also constitute the choice non invasive follow up method in these patients.
