Results
All WMH identified in the current study involved the subcortical and deep white matter of the supratentorial regions,
while none infratentorial WMH were detected (Tables 1 & 2).
WMH (Fig.
7 & 8) were found in 15/30 (50%) of migraineurs with SV>50 μl,
in 5/22 (22.7%) of migraineurs with SV<50 μl and in 5/16 (32%) of normal controls.
SV in patients (80.4±43.9 μl) was significantly higher (p<0.05) than in controls (64.4±31.3 μl).
All controls with WMH had SV>50 μl and no WMH were detected in controls with SV<50 μl.
Type III VRS (Fig.
9) were found only in the migraineurs group (15.3%).
ALV was identified in 30.7% and 12.5% of patients and controls,
respectively.
Minimal to mild sinusitis,
probably without clinical significance,
was diagnosed in 16/52 (30.7%) of migraineurs and in 3/16 (18.7%) of controls.
55.7% of patients and 62.5% of control subjects were diagnosed with CVS agenesis or hypoplasia (Fig 10).
In these cases,
however,
there was no evidence of development of collateral drainage through secondary extracranial venous channels to suggest previous venous thrombosis.
No significant difference was found regarding the size of the suprasellar cistern between the migraineurs and the normal subjects.The total area of the suprasellar cistern in the migraineurs ranged from 93 mm2 to 242 mm2 (mean 162.7 mm2) and in the normal subjects from 72 mm2 to 234 mm2,(mean 166.9 mm2).
However,
the height of the pituitary gland was higher in the migraineurs than in the normal subjects,
ranging from 2.8 mm to 7.6 mm (mean 5.1 mm) in the migraineurs compared to a range between 1.8 mm and 6.3 mm (mean 4.2 mm) in the normal subjects.
No definite pituitary adenoma was detected,
although the presence of a tiny,
non-functional adenoma could not be definitively excluded since the pituitary gland was not examined with the proper dynamic post contrast protocol.
