However, as with the case presented here, the coincident existence of a sellar mass should not preclude the possibility of an ectopic source. [ncbi.nlm.nih.gov]

Hyperprolactinemia Prolactin secreting pituitary adenomas present four times as frequently in women as in men. It should be noted that both the age of presentation and symptomatology at presentation are markedly different in the sexes. [med.virginia.edu]

Exophthalmous is present only in Grave’s disease (primary hypersecretion).[ 5 ] Non-secreting adenomas (neurological presentation) Hormonally inactive tumors tend to get to a larger size before detection. Non-specific sympthoms include headache. [primarycare.imedpub.com]

• Weight Gain

  Patients are often diagnosed with Cushing’s disease after several years of symptoms which might include progressive weight gain, new onset hypertension or diabetes and mood changes. [pacificneuroscienceinstitute.org]

GENERAL PRINCIPLES OF DIAGNOSIS AND TREATMENT Patients presenting with signs and symptoms suggestive of a pituitary adenoma require a comprehensive workup and treatment plan reflecting a strong interdisciplinary effort with endocrinologists, neurosurgeons [med.virginia.edu]

While a majority of patients with endogenous Cushing syndrome have thyrotrophic adenomas (called Cushing Disease - see below), other tumors should also be considered as part of the endocrinologic workup, including adrenal tumors and especially ACTH-secreting [eyewiki.aao.org]

Dynamic pituitary MRI has high sensitivity and specificity for diagnosis of mild Cushing's syndrome and should be part of the initial workup. Horm Metab Res. 2007;39(6):451–456. 22. Rennert J, Doerfler A. Imaging of sellar and parasellar lesions. [aafp.org]

• Enlarged Sella

  Empty Sella An empty sella occurs as a result of herniation of the arachnoid through an incompetent diaphragma sellae. Over time, cerebrospinal fluid (CSF) pulsations may enlarge the sella and compress the gland against the floor of the sella. [emedicine.medscape.com]

Radiation and pharmaceutical treatment may be alternative for recurrent Cushing disease. [ncbi.nlm.nih.gov]

As the treatment time or treatment concentration increased, KML001 significantly increased the percentage of AtT-20 cells in apoptosis. [endocrine-abstracts.org]

Treatment for Cushing’s Disease The primary treatment for Cushing’s disease is surgery to remove the pituitary tumor. [mskcc.org]

Pituitary Tumor Treatment Without Surgery Medical management with drugs through an endocrinologist is the first-line treatment for pituitary adenomas secreting prolactin. Pituitary tumors rarely require any other treatment. [texasspineandneurosurgerycenter.com]

Treatment and prognosis Management depends on the specific etiology 6. [radiopaedia.org]

Surgical removal has a guardedly favorable prognosis, but long-term follow-up is required. [skullbaseinstitute.com]

People with small tumors that do not need immediate treatment or can be completely removed with surgery have an excellent prognosis. Even for large tumors that interfere with vision, surgery can stop further deterioration of vision. [drugs.com]

Prognosis Remission can be obtained in up to 90% of patients with microadenomas and in about 50% to 60% of those with macroadenomas. [ 1 ] [patient.info]

Additionally, it can result in Nelson syndrome in 10% to 30% of patients and carries a generally unfavorable prognosis. [ncbi.nlm.nih.gov]

Treatment and prognosis Management depends on the specific etiology 6. [radiopaedia.org]

In none of these cases, however, was the diagnosis of an ACTH-secreting chromophobe adenoma established at the outset, and the present evidence favoring a pituitary etiology is based on retrospective reasoning and demonstration of abnormally high levels [nejm.org]

[…] stimulation is also advocated in conjunction with the dexamethasone suppression test in order to increase sensitivity. 55 In patients where this testing is not compelling, inferior petrosal sinus sampling (IPSS) must be performed to confirm the pituitary etiology [ncbi.nlm.nih.gov]

Hyperprolactinemia Present Biologically inactive form of prolactin, with no pathologic association Useful to check in patients with hyperprolactinemia who have moderate elevations (100 to 300 mcg per L [4,348 to 13,043 pmol per L]) of serum prolactin with unknown etiology [aafp.org]

It also suggests, however, that pituitary adenomas may arrive by different pathophysiologic pathways. Non-hormone-secreting pituitary tumors tend to grow slowly and insidiously. [glowm.com]

Promising preventive measures may include preoperative routine sputum smear and India-ink stain for screening, preoperative treatment of cryptococcal pneumonia, postoperative antibiotic management, and a more secure skull base reconstruction. [ncbi.nlm.nih.gov]

It may be recommended as additional therapy after surgery to prevent regrowth of the tumor. Radiation may also be used as the sole treatment if the tumor cannot be removed surgically, or if the tumor regrows after surgery. [mskcc.org]

We believe seeing both specialists at the same time reduces anxiety and uncertainty for the patient, and prevents having to go back and forth between specialists. [uofmhealth.org]

Prevention Pituitary adenomas are not associated with any known lifestyle or environmental risk factors, so there are no available methods to prevent the condition. [innerbody.com]
