| | Pituitary Tumors |
 | | Pituitary adenomas are benign tumors (meaning that they are non-cancerous and do not travel to other parts of the body) that arise exclusively within the anterior pituitary. | | | Large adenomas may also present with headaches due to: 1) the adenoma pressing against nearby brain structures, 2) an increase in intracranial pressure (the pressure within the skull, which can compress the brain if the pressure increases), or 3) a blockage of the ventricles within the brain causing hydrocephalus. | | | Pituitary tissue is acquired through biopsy at the time of surgical removal. |

| | The conventional surgical methods for removal of pituitary adenomas involve incisions under the upper lip or in the nostril. | | | endoscopic pituitary surgery is performed through a natural nasal air pathway without any incisions (unlike the conventional microscopic surgery performed with an incision made under the upper lip or inner aspect of a nostril). | | | Although this patient was referred for an invasive craniotomy surgery due to the hard fibrotic nature and large suprasellar protrusion of the tumor, endoscopic transspehnoidal surgery via a nostril was performed instead. |

| | This approach allows for more accurate tissue destruction of an adenoma, and therefore spares normal brain tissue.[1] This technique is also useful for recurrent pituitary adenomas prior to surgery and/or radiation. Considering your patient's age, clinical picture, and general health, she sounds like an ideal candidate for medical therapy. | | | The neurosurgeon she was referred to is considering medical treatment with bromocriptine. | | | However, approximately 25% to 30% of patients have pituitary tumors that are not associated with a hypersecretory component.[2] The tumors not associated with increased hormone secretion are referred to as clinically nonfunctioning adenomas. |

| | The symptoms of a pituitary adenoma depends on what hormone it secrets. | | | • Pituitary adenomas used to be classified by the color of their cytoplasm, acidophilic, chromophobe and basophilic, but these colors give no clue as to which hormone is being secreted. | | | •Cytoplasm may be acidophilic, pale pink or basophilic but usually is of only one color in a single adenoma. |

| | Pituitary Adenoma |
| | ituitary adenomas typically exert pressure on the chiasm in the midline from below. | | | The exact sites of nerve fiber compression may show some variation, depending on whether the chiasm is prefixed (has short optic nerves), in the middle position (by far the commonest case), or postfixed (with long optic nerves). | | | Ventral crossed fibers, which originate from the inferior nasal retinas, are thus the ones that show the earliest signs of involvement, accounting for bilateral superior temporal defects in the visual fields (superior bitemporal quandrantanopia). |

| | pituitary adenoma |
| | Increased levels of hormones can lead to either Cushing disease or acromegaly. | | | Secondary effects of tumor growth can lead to compression of the optic chiasm which has a position slightly above and in front of the pituitary gland. | | | Initially the tumor results in either an increase or decrease of hormone production depending on whether or not the adenoma is composed of cells capable of producing hormone. |
