The effects of local mass effect on the pituitary gland are a feature associated with mass increases of the pituitary gland, visual field abnormalities caused by compression on optic nerves, and chiasm by expanding the pituitary gland. A pituitary adenoma may result in elevated Intracranial Pressure symptoms such as nausea, vomiting, and headache.
What are the Effects of Local Mass Effects on the Pituitary Gland?
Illustrative case. A 22-year-old male patient presented with visual field defects. A: Initial MRI showed pituitary adenoma. B: Suspicious residual mass identified after the operation. C: 1-yr postoperative MRI showed progression. The patient was lost to follow-up without any further treatment. D: 6-yr postoperative MRI showed significant progression with hydrocephalus. E: After the second operation, intracerebral hemorrhage with intra-ventricular hemorrhage occurred. F: An adjuvant gamma knife radiosurgery was conducted on the residual tumor.
