This can be due to severe hypothyroidism or adrenal insufficiency with resultant over-production of TSH (for thyroid) and/or ACTH (adrenal). Other causes include pituitary lumps (adenoma) or normal variant. A complete look at the pituitary hormones and a followup MRI with focus on the pituitary is the usually course of action.
