The key steps in management of pituitary lesions are determined by: 1) pituitary function, particularly by determining which hormones are being over- or under-produced; 2) the presence of neurological deficits (visual field disturbances, headache or ophthalmoplegia) that are directly related to a pituitary mass affecting local structures; 3) evidence of pituitary lesion growth on serial imaging. These factors will determine whether medical or surgical management, typically via transsphenoidal resection, should be pursued. Pituitary lesions that are shown to over- or under-produce hormones should undergo evaluation for surgery. The exception is a prolactin-secreting pituitary lesion, or prolactinoma, which can be medically managed with the use of dopamine agonists (cabergoline and bromocriptine), unless side effects prevent its use. Once hormonal abnormalities are identified, it is suitable to involve endocrine subspecialists. If a patient with visual field disturbances, ophthalmoplegia, or ...
Pituitary abscess is a rare condition with nonspecific symptoms that can be delayed. Proper diagnosis needs to occur preoperatively so that the management can be set up accordingly. Accurate diagnosis is challenging because many differential diagnoses can exhibit the same magnetic resonance imaging features. We report two cases of pituitary abscess. The first patient was a 66-year-old Arab woman who underwent a surgical procedure for a pituitary macroadenoma and presented 3 months later with chronic headaches and panhypopituitarism. A pituitary abscess was found on the follow-up magnetic resonance imaging. The second patient was a 64-year-old Arab man with no medical history who presented with a chiasmal syndrome with headaches and panhypopituitarism. Brain magnetic resonance imaging showed a heterogeneous pituitary mass that turned out to be a pituitary abscess intraoperatively. These two patients were treated with hormone substitution, endoscopic transsphenoidal drainage, and antibiotherapy, with

The contribution of autoimmune phenomena to dysfunction of hypophysis or hypothalamus is far to be unraveled and also the specific pathways of hypophysitis are poorly understood until now, mostly for the pediatric population. Primary hypophysitis is rare in children and often regarded as an autoimmune disorder, following the evidence of lymphoplasmacytic infiltration in the pituitary gland, detection of anti-pituitary antibodies (APA) and anti-hypotalamus antibodies (AHA) by indirect immunofluorescence on cryostatic sections of human or primate hypophysis and hypothalamus, and coexistence with other autoimmune disorders. The rarity of this condition and the lack of ad hoc studies make hard any assessment of the real incidence of hypophysitis in pediatric patients, and also the role of APA and AHA has been poorly investigated in children with idiopathic hypopituitarism. Potential target autoantigens studied in autoimmune hypophysitis have been various pituitary-specific factors, chaperone ...
Our neuroendocrine team treats pituitary disease and other neuroendocrine disorders using the latest minimally invasive surgical techniques.
Magnetic resonance imaging is the most important diagnostic method in the investigation of the pituitary lesions. Our aim is to determine whether T2-weighted coronal images may be helpful in the evaluation of the pituitary gland with suspected pituitary adenomas. One hundred and sixty-seven patients were examined prospectively with T2-weighted coronal and T1-weighted coronal images enhanced with intravenous contrast material. The images were evaluated for the presence, the size, the location, and the ancillary signs including sellar floor erosion or ballooning, infindibulary deviation, convexity of the superior border of the gland, diffuse enlargement of the gland, and the invasion of the cavenous sinuses on both images. In forty-six (28%) patients lesions were revealed on both sequences. In twenty-one (12%) patients the lesions that were revealed on the T1-weighted images were not detected on the T2-weighted images. Positive predictive value, negative predictive value, sensitivity,
Pituitary adenomas are found in 10%-25% of unselected autopsy series and are evident in about 10% of asymptomatic individuals by magnetic resonance imaging. Diagnosis of pituitary disorders is often delayed by lack of awareness and the subtlety of symptoms and signs. Hypopituitarism is suspected when peripheral hormone concentrations are low without an elevation in the corresponding pituitary tropic hormone(s). Severe adult-onset growth-hormone deficiency results in reduced muscle mass, increased fat mass and diminished quality of life, which are reversed by growth hormone replacement therapy. While trans-sphenoidal surgery remains first-line treatment for acromegaly, drug treatment has an important role in controlling residual growth-hormone excess and, in some circumstances, as first-line treatment. Dopamine-agonist therapy (cabergoline or bromocriptine) is the treatment of choice for micro- and macroprolactinomas. In patients with suggestive clinical features, elevated 24-hour urine free cortisol

Patients treated with immunosuppressive drugs, especially methotrexate (MTX), rarely develop lymphoproliferative disorders (LPDs), known as MTX-related LPD (MTX-LPD). The primary site of MTX-LPD is often extranodal. This is the first reported case of MTX-LPD in the pituitary. A 65-year-old woman was admitted to our hospital with symptoms of oculomotor nerve palsy and multiple subcutaneous nodules. She had been treated with MTX for 11 years for rheumatoid arthritis. Computed tomography showed multiple masses in the orbit, sinuses, lung fields, anterior mediastinum, kidney, and subcutaneous tissue. Brain magnetic resonance imaging revealed a sellar mass. She was diagnosed with hypopituitarism and central diabetes insipidus based on endocrine examination. Although pituitary biopsy could not be performed, we concluded that the pituitary lesion was from MTX-LPD, similar to the lesions in the sinuses, anterior mediastinum, and subcutaneous tissue, which showed polymorphic LPD on biopsy. MTX was ...
The pituitary gland is a tiny, pea-sized gland that controls the function of most other endocrine glands in the body. It is therefore sometimes called the master gland. It can over- or under-produce hormones that effect the thyroid, adrenal, testes and ovaries. It also controls growth and water balance. The gland is located at the base of your brain and can develop tumors that are almost always benign. Although the tumors are not generally cancerous, they can cause several difficulties, including vision problems, headaches and other health problems ...

Background: Lymphocytic hypophysitis and Sheehan s syndrome are rare disorders predominantely affecting women in the peripartum period. Patients usually present with various degrees of hypopituitarism and/or symptoms of a pituitary mass lesion.. Material and methods: We present two case-histories of postpartum hypopituitarism. We have also performed a review of literature from Medline and Pubmed databases.. Results and interpretation: Sheehan s syndrome is a pituitary necrosis due to hypotension during an obstetric bleeding. Lymphocytic hypophysitis is a chronic inflammatory process of the anterior pituitary gland, where the pathogenesis is believed to be autoimmune. The diagnoses should be considered when women present peripartum with non-specific symptoms related to varying deficiencies of anterior pituitary hormones, and/or headache and/or visual disturbances.. The treatment of hypopituitarism mainly consists of hormone-replacement therapy with careful follow-up ...
Hypothalamic-pituitary disease is a well-recognized, although uncommon, occurrence in sarcoidosis. Almost always the endocrine manifestations occur in a patient with widespread disease involving the lungs, skin or liver. A case is reported of central nervous system (CNS) sarcoidosis with no other clinical, biochemical or histological evidence of the disease.. ...
The vast majority of microprolactinomas and macroprolactinomas respond to ergot derived dopamine receptor agonists such as cabergoline or bromocriptine. For many patients cabergoline has a more satisfactory side effect profile than bromocriptine, and at doses used for pituitary disease, psychoses and clinically significant fibrotic reactions are rare. Microprolactinomas change little in size with treatment but macroprolactinomas can be expected to shrink, sometimes quite dramatically. Although not teratogenic, dopamine receptor agonists are withdrawn as soon as pregnancy is confirmed and visual fields checked at intervals to identify the small proportion of women whose macroprolactinomas enlarge significantly.. It is important that the objectives of microprolactinoma treatment are kept in mind. In a patient with galactorrhoea, reducing prolactin concentrations with dopamine analogues is clearly central, but for women in whom the problem of hyperprolactinaemia relates only to suppressed oestrogen ...
Cystic sellar lesions are a rare cause of hypopituitarism and extremely rare in the pediatric age group. The differential diagnosis is large and includes both primary pituitary abscesses and cystic components on pre-existing lesions, such as adenoma, craniopharyngioma, Rathkes cleft cyst, leukemia, granulomatous disease and lymphocytic hypophysitis. In the absence of a definitive diagnosis, treatment can be challenging. We report a case of a 15-year-old female, who presented with headaches, altered consciousness and diplopia after a molar extraction, for which she had received oral antibiotics. Broad-spectrum i.v. antibiotics were given for presumed meningitis. Blood cultures failed to identify pathogens. Cerebral magnetic resonance imaging showed a pituitary cystic lesion. Endocrine studies revealed abnormal pituitary function. In the absence of a therapeutic response, the patient underwent a transsphenoidal biopsy of the pituitary gland, which yielded a purulent liquid, but cultures were ...

A Rathkes cleft cyst is a benign growth found on the pituitary gland in the brain, specifically a fluid-filled cyst in the posterior portion of the anterior pituitary gland. It occurs when the Rathkes pouch does not develop properly and ranges in size from 2 to 40mm in diameter. Asymptomatic cysts are commonly detected during autopsies in 2 to 26 percent of individuals who have died of unrelated causes. Females are twice as likely as males to develop a cyst. If a cyst adds pressure to the optic chiasm, it may cause visual disturbances, pituitary dysfunction, and headaches. The majority of pituitary patients with chronic headaches have Rathkes Cleft Cysts. This is believed to be caused by the constant change in volume and the drastic changes in vasopressure from fluctuations in gonadotrophs and ADH. The treatment of choice for symptomatic cysts is drainage and taking a biopsy. Radical excision is more dangerous because of the potential of damaging the patients pituitary function e.g. ADH ...
This patient presented with hyperprolactinemia. MRI reveals T1/T2 hyperintense lesion in the left posterior aspect of the pituitary with convex superior margin with minimal enhancement on post contrast scans. The pituitary stalk is deviated to right. Fluid level is noted in the axial section. The optic chiasm & cavernous sinus appears normal. No parasellar abnormality. Differentials include first differential of rathkes cleft cyst versus other possibility of cystic adenoma. Rathkes cleft cysts are nonneoplastic, sellar or suprasellar epithelium-lined cysts arising from the embryologic remnants of Rathkes pouch in the pituitary gland. Hyperprolactinemia in Rathke cleft cyst is due infundibular stalk compression. ...
The Pituitary Network Association (PNA) is a nonprofit organization which was formed in 1992 in Los Angeles, California, as the Acromegaly Network Association. Patients referred to PNA receive information on pituitary adenomas and peer-counseling. The lack of clear and concise written information about the various pituitary adenomas, and the difficult and intricate illnesses and afflictions associated with the many types of adenomas led the Association to engage some of the worlds leading scientists, endocrinologists, and neurosurgeons to write information booklets and brochures, in laymans language.
