A member asked:
What is this mean on cta ? the left transverse sinus is diminutive?
3 doctors weighed in across 2 answers
The transverse sinus is part of venous structure that collects blood form the brain and drains to the jugular. A diminutive sinus means the vein is congenitally smaller than typical. There is a lot of normal variation in the transverse sinuses in terms of size and drainage pattern, and these variations usually cause no issues. Interestingly, the left transverse sinus has more normal variation.

This represents a congenital structural variant and has no clinical correlative significance. Meet with your doctor to discuss the next steps in view of this outcome.
