Cushing Disease After Treatment of Nonfunctional Pituitary Adenoma

We describe a very rare case of nonfunctional pituitary adenoma (NFPA) that exhibited corticotrophic activity after resection and radiotherapy. The possible mechanisms of the transformation from NFPA to Cushing disease (CD) are discussed.A 43-year-old man presented with impaired vision, bilateral frontal headaches, and hyposexuality. He had no symptoms suggestive of hypercortisolism, and 8 am p...

Relapse in pituitary adenoma after resection

Pituitary adenoma in children is rarely reported. Acromegaly is one of clinical manifestation in GH releasing-pituitary adenoma. Recurrence of clinical manifestation after resection must be evaluated for possibility of pituitary adenoma relapse. N,male,15-yo, came to pediatric endocrinology outpatient clinic with the main complain of acromegaly and decreased of visual field which was getting wo...

Fibrosarcoma after high energy radiation therapy for pituitary adenoma.

Pituitary sarcoma is a rare late complication of radiotherapy for pituitary tumors. Although early case reports involved multiple courses of relatively low-energy radi ation therapy, pituitary sarcoma has been seen with single courses of high-energy x-ray or heavy particle radiotherapy . This report describes a fibrosarcoma of the pituitary occurring 5 years after 4,500 rad (45 Gy) of X-irradia...

Short-term preoperative octreotide treatment for TSH-secreting pituitary adenoma.

Preoperative control of hyperthyroidism in patients with TSH-secreting pituitary adenomas (TSHoma) may avoid perioperative thyroid storm. Perioperative administration of octreotide may control hyperthyroidism, as well as shrink tumor size. The effects of preoperative octreotide treatment were assessed in a large number of patients with TSHomas. Of 81 patients who underwent surgery for TSHoma at...
