Abstract
The authors analyzed whether the pituitary gland enlarges in intracranial h ypotension syndrome by studying 11 consecutive patients. Initial MRI scans showed pituitary gland enlargement with a convex superior margin. Follow-up MRI studies revealed that the size of the gland invariably diminished in a ll patients. The authors hypothesize that pituitary gland enlargement in in tracranial hypotension syndrome is due to hyperemia of dural and epidural v enous sinuses.
