Abstract :

Purpose:

MR venography is an important tool for evaluation of vascular headache and its helps to identify the cereal venous thrombosis. This study is to identify the anatomical variations in the cereal venous sinus and the gender difference in the population who have attended the headache clinic for evaluation .Knowledge of normal variant in the cereal dural venous sinus anatomy seen on magnetic resonance(MR) venography is essential to diagnosis of normal variant cereal venous sinus and to avoid overdiagnosis of cereal venous thrombosis.

Materials and Methods:

A retrospective study was conducted to study the normal anatomy of the intracranial venous system and its normal variation, as depicted by 3D MR venography, and any gender–related differences in patients those were treated for vascular headache from October 2017 to november2017 in K.A.P.V.Govt.Medical College and Mahatma Gandhi Memorial Govt.Hospital

Results:

A total of 40 patients (13 men, 27 women, age range 06 to 70years) were included in the study.

Hypoplastic in left transverse sinus and sigmoid sinus was the most common anatomical variation in 15 (37.5%) patients. Left transverse sinus was hypoplastic in more commonly in female in comparison to male (80% versus 20%).

Hypoplastic in right transverse sinus and sigmoid sinus was the most common anatomical variation in 04 (10 %) patients. Right transverse sinus was hypoplastic in more commonly in female in comparison to male (75% versus 25%).

Normal anatomical variation of transverse sinus and sigmoid sinus in 21 (52.5%) patients.

Conclusion:

Hypoplastic left transverse sinus is the most common anatomical variation and more common in female compared to male in the present study. Other anatomical variations of dural venous sinuses are not significantly differ among both genders.
