Cerebral venous sinus thrombosis.

c erebral venous sinus thrombosis is an uncommon condition, which over the past 10 years has been diagnosed more frequently due to greater awareness and the availability of better non-invasive diagnostic techniques. Because of the generally good prognosis and variable clinical signs, many cases remain clinically undetected but some patients suffer complications and die. CVST is slightly more common in women, particularly in the age group 20–35, due to pregnancy, puerperium and oral contraceptive use. The mean age in different studies was 37–38 years, although all ages can be affected [1-4]. The clinical spectrum, however, is wide and recognition remains a challenge for the clinician [1-8].
