Geometric survey on magnetic resonance imaging of growth hormone producing pituitary adenoma.

abstract：CONTEXT:Outcome of acromegaly surgery is assessed by IGF-1 and glucose-suppressed GH, but whether the latter provides additional clinically relevant information when IGF-1 is normal is unclear. The role of GH suppression testing after surgery requires clarification. METHODS:We studied 97 acromegaly patients with norma...

abstract：:Aggressive pituitary adenomas are notoriously difficult to manage due to their size, invasiveness, speed of growth and high frequency of recurrence. Except for prolactinomas, surgery (usually transsphenoidal but sometimes transcranial) is the first-line option, but re-growth of aggressive tumors is almost inevitable a...
