Aims and objectives
It is well known that migraines are associated with brain white matter hyperintensities (WMH) in magnetic resonance imaging (MRI) studies (1-16).
Migraines are often debilitating headaches,
which might cause white matter changes,
and to a lesser degree,
silent posterior vascular territory infarcts (8,10).
However,
several studies reported supratentorial,
but not infratentorial,
WMH in migraineurs,
probably due to differences in patient selection (9).
A lot of studies attempted to analyze the underlying pathophysiology of migraines (11-16) suggesting several causes of WMH in migraine,
such as oligemia and focal hypoperfusion (11,12),
autoimmune (13),
or inflammatory (14-16) processes.
The main purpose of the current MRI study was to investigate the relation between WMH in migraineurs,
as well as in control subjects,
and the aqueductal flow characteristics of the cerebrospinal fluid (CSF).
Morphological characteristics,
such as the suprasellar cistern size and pituitary gland height were also studied.
In addition,
the prevalence of Virchow Robin spaces (VRS),
agenesis/hypoplasia of the cerebral venous sinuses (CVS) (to exclude previous venous thrombosis),
asymmetry of the lateral ventricles (ALV) and minimal-mild sinusitis were comparatively assessed in the two groups studied.
