A Rathke's cleft cyst is a benign growth on the pituitary gland in the brain, specifically a mucin-filled [1] cyst in the posterior portion of the anterior pituitary gland. [ 2 ] [ 3 ] It occurs when the Rathke's pouch does not develop properly and ranges in size from 2 to 40 mm in diameter.
[63] [64] Pituitary microadenomas are smaller than 10 mm in diameter and are generally considered benign, yet the presence of a microadenoma has been positively identified as a risk factor for suicide. [65] [66] "... patients with pituitary disease were diagnosed and treated for depression and showed little response to the treatment for ...
It grows at the base of the brain from the pituitary gland. This tumor is thought to be derived from the parenchymal cells of the posterior lobe of the pituitary gland, called pituicytes. Some researchers [1] believe that they arise from the folliculostellate cells in the anterior lobe of the pituitary. As such, it is a low-grade glioma.
Pituitary adenomas are tumors that occur in the pituitary gland. Most pituitary tumors are benign, approximately 35% are invasive and just 0.1% to 0.2% are carcinomas. [1] Pituitary adenomas represent from 10% to 25% of all intracranial neoplasms, with an estimated prevalence rate in the general population of approximately 17%. [1] [2]
In contrast to major depression, dementia is a progressive neurodegenerative syndrome involving a pervasive impairment of higher cortical functions resulting from widespread brain pathology. [ 7 ] A significant overlap in cognitive and neuropsychological dysfunction in dementia and pseudodementia patients increases the difficulty in diagnosis.
This is a shortened version of the third chapter of the ICD-9: Endocrine, Nutritional and Metabolic Diseases, and Immunity Disorders. It covers ICD codes 240 to 279 . The full chapter can be found on pages 145 to 165 of Volume 1, which contains all (sub)categories of the ICD-9.
Frontal arachnoid cysts have been associated with depression. [12] Cysts on the left temporal lobe have been associated with psychosis. [13] [14] A left fronto-temporal cyst showed symptoms of alexithymia. [15] Cyst on the right sylvian fissure resulted in new onset of schizophrenia-like symptoms at age 61. [16]
The pituitary gland consists of two parts, the anterior (front) and posterior (back) pituitary. Both parts release hormones that control numerous other organs. In pituitary apoplexy, the main initial problem is a lack of secretion of adrenocorticotropic hormone (ACTH, corticotropin), which stimulates the secretion of cortisol by the adrenal ...
