Essentials in pituitary carcinomas:. Only 1% of pituitary adenomas are carcinomas. Pituitary carcinomas showing nearby or distant mts, such as seeders and to the lung. ACTH-secreting pituitary carcinomas have tendency to metastases outside CNS. Histologic verification solely in clinico-morphologic background. Spread along the spinal subarachnoid space may lead to metastases in the spinal cord or cauda equina. Clinical Features and Therapy. The onset of diabetes insipidus early in the course of the diseas...

Benign Pituitary Cysts

http://www.neurooncology.ws/benignpituitarycyst.htm

Essentials in benign pituitary cysts:. Benign pituitary cysts are a common finding in autopsy studies and can occasionally become large enough to cause symptoms by compression of the intrasellar or suprasellar structures. Although cysts in the sella and suprasellar region are a diverse group of entities, they are often indistinguishable on the basis of clinical and radiographic findings, and a diagnosis can often be made only by gross and histologic examination. CT typically shows an enlarged sella turci...

Pituitary Apolpexy

http://www.neurooncology.ws/pituitaryapoplexy.htm

Essentials in pituitary apoplexy:. There are now hundreds of case reports of pituitary apoplexy in the literature, which have provided useful data on the incidence, predisposing factors, pathologic findings, putative pathophysiologic mechanisms, clinical features, radiologic concomitants, and treatment of this fascinating condition. Ller-Jensen and L ϋ. Other symptoms of an abrupt and potentially catastrophic intracranial ictus, possibly secondary to acutely increased intracranial pressure and/or hypotha...

Prolactinomas

http://www.neurooncology.ws/prolactinomas.htm

Any space-occupynig lesion lesion in the sella can cause elevation of prolactine up to 150 ng/ml. The golden treatment of prolactinomas is surgical removal, irrespective of their size. The most common complication in transsphenoidal surgery is CSF leak. The physiologic effects of prolactin are not completely understood, but it is believed to act in concert with several other hormones, including estrogen, progestins, oxytocin, corticosteroids, growth hormone, and insulin. As with other pituitary tumors, p...

Empty Sella Syndrome

http://www.neurooncology.ws/emptysella.htm

Essentials for empty sella syndrome:. Empty sella syndrome is not a rare finding and it can be seen in 30% of population over the age of 30 years. This finding must be considered with context with other pathological features. The most common cause is a wide aperture in the diaphragma sella, which is a normal anatomical variation. Little clinical attention was initially paid to Busch's interesting findings. Both radiologists and neurosurgeons usually regarded nontumoral sellar enlargement as reflectin...

Nonsecretory Pituitary Adenomas

http://www.neurooncology.ws/nonsecretorypituitaryadenomas.htm

Essentials in nonsecretory pituitary adenomas:. Chromophobe adenomas could rise prolactin levels up to 200 ng/ml. Mass effect is the main determinant in clinical picture. Surgery and radiation is the accepted modality of treatment. Complications are the same for other space-occupying lesions in the sellar region. Loss of libido is found most often in men. There may also be other symptoms and signs of panhypopituitarism in either men or women, with amenorrhea, sexual disinterest, smooth, pale skin, an...

Endocrine Diagnosis in Pituitary Adenomas

http://www.neurooncology.ws/endocrinediagnosis.htm

Table-1 Screening tests after total hypophysectomy. Table-2 Normal endocrine value. Thyroid stimulating hormone (TSH). Follicle stimulating hormone (FSH). Assessment of Normal Pituitary Function. Stimulates the release of growth hormone through the alpha-adrenergic receptor mechanism and is more effective in women than in men. After its infusion in normal individuals, growth hormone levels generally rise to more than 5 ng/m! Again, any detectable level indicates the presence of surviving somatotropes.

Imaging of Sellar Lesions

http://www.neurooncology.ws/imagingsellarlesions.htm

Essentials in imaging of the sellar region:. Evaluation of the sella using MRI requires images with optimal spatial and contrast resolution and minimal background noise. Many lesions in this area are very small. This requires small pixel size and thin slices. T1-weighted MR images are currently the best method for demonstrating the anatomy of the sella and parasellar regions. The most common lesions in this region are the pituitary adenoma, craniopharyngioma, meningioma, carotid aneurysm, and optic and h...
