Pituitary or pituari is an important part of the endocrine system and is often called the master gland since it controls several other hormones such as adrenaline gland and thyroid. The pituitary gland is located in a hollow bone called the pituitary fossa which is behind the nose and at the base of the brain, adjacent to the optic nerve. The pituitary gland is a pea and consists of two parts or lobes.
PITUITARY INFARCTION SYMPTOMS
Pituitary tumor is intracranial neoplasm is relatively common, and is 10-15% of all intracranial neoplasm. This type of tumor is often difficult to treat and is not uncommon, although Chan has done surgical action. Although there has been a lot of research on the pathogenesis of pituitary tumors, the occurrence of these tumors has not been entirely clear. Generally considered that pituitary neoplasm is a primary tumor pituitary. Biomolecular research suggests that the pituitary tumor, either functioning or non functioning, derived from one clone growth (monoclonal).
PITUITARY INFARCTION PREGNANCY
Posterior pituitary does not produce its own hormones, but retain fluids secreted by the hypothalamus to balance hormone called anti-diuretic hormone (ADH) and oxytocin. Antidiuretic hormone (ADH) or vasopressin because it inhibits the production of dilute urine in the body. The hormone oxytocin plays an important role in the contraction of the uterus during and after childbirth. These hormones also affect milk production, and hormone affection to build an emotional bond.
PITUITARY INFARCTION POSTPARTUM
Pituitary adenomas are found on CT or MRI without any symptoms or signs that indicate the presence of a pituitary disorder often called incidentaloma. The prevalence of pituitary incidentaloma found on MRI by approximately 10%, and almost 99.5% of them are microadenomas.
Microadenomas also reportedly found in the 1.5 - 27% of autopsy cases without suspicion pituitary disorders. Most pituitary tumors are found in young adults, but can also be found in adolescents and the elderly. While other sources wrote that pituitary tumors can be found at all ages, but the incidence increases with increasing age of 8.9 years, and a peak between the third and fifth decade.
PITUITARY INFARCTION PROGNOSIS
In order to obtain the best estimate of the prevalence of pituitary adenomas in population, has made a meta-analysis of 12 manuscripts (7 autopsy examination and radiological examination 5). The results showed that, there is a clear relationship between the prevalence of the methodology used.
With a sensitive technique microadenomas the prevalence of about 20%, at least 1/3 of the tumor is clinically important because it produces one or more anterior pituitary hormones, macroadenomas found in 1/555 of the population aged over four decades. Based on these findings mean many patients with micro- and macroadenomas often undiagnosed. So that efforts should be made to improve tumor detection
