| Abstract | ||||
| Background: Dural venous sinuses (DVSs) are venous channels that connect the endosteal and meningeal layers of the dura mater in the brain. They include the superior sagittal sinus (SSS), inferior sagittal sinus (ISS), straight sinus (SS), confluence of sinuses (torcular Herophili), transverse sinuses (TS), and sigmoid sinuses. Objective: We conducted this study to use the MRV to depict the prevalence of anatomical variants of DVSs in Sohag population, which can help to avoid potential pitfalls in the diagnosis of DVS thrombosis, and venous hemorrhage. Patients and methods: This cross-sectional study was carried out on 169 patients (80 male, 89 female) attended to Sohag University Hospitals. Routine MRI brain sequences were done with complementary maximum intensity projection (MIP) 3D TOF MRV. Results: This study included 169 patients with age range from 3 months to 84 years, MRI examination of studied patients showed that 35 patients (20.7%) had left attenuated/asymmetrical transverse sinus, right attenuated/asymmetrical transverse sinus prevailed in 7.1%. MRI examination of sigmoid sinus of studied patients showed that 24 patients (14.2%) had left attenuated/asymmetrical sinus, right attenuated/asymmetrical sinus prevailed in 2.4%. Concerning SSS, a larger percentage of patients (89.9%) had type I. About 10% of patients had abnormal SSS. Conclusion: Neuroradiologists must be familiar with common dural venous anatomical variations to accurately differentiate normal variance from pathology. | ||||
