The thymus gland is quadrilateral with convex borders. It fills the perivascular space.
Case Discussion
The appearance of the large normal thymus gland in pediatrics should be familiar to the radiologist and not be mistaken for a pathology. on CT, it appears quadrilateral with convex borders in children younger than 5 years. As the child grows, it gets smaller in size and becomes triangular in appearance with straight or concave borders.
