I had a brain mri done because I been having very bad headaches, it showed I had a 6 mm cystic microadenoma at the left lateral aspect of the pituitary gland. What problems does this cause? Can it cause headaches??
Most of the time a 6mm cystic lesion in the pituitary gland causes no symptoms. Rarely it can be a source of headaches. When the headaches are caused by pituitary cysts, they usually are daily and have a occipital projection (back of the head).
Other symptoms can be present if the cyst is a functional adenoma. In this situation hormones are produced by the tumor and they cause changes in the body. These changes are related to Cushing's disease, acromegaly, prolactinemia (milk production etc).
