Nelson's syndrome is a disorder that occurs in about one in four patients who have had both adrenal glands removed to treat Cushing's disease. [1] In patients with pre-existing adrenocorticotropic hormone ()-secreting pituitary adenomas, loss of adrenal feedback following bilateral adrenalectomy can trigger the rapid growth of the tumor, leading to visual symptoms (e.g. bitemporal hemianopsia ...
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 and the estimated prevalence rate in the general population is approximately 17%. [ 1][ 2]
A brain tumor occurs when abnormal cells form within the brain. [ 2] There are two main types of tumors: malignant (cancerous) tumors and benign (non-cancerous) tumors. [ 2] These can be further classified as primary tumors, which start within the brain, and secondary tumors, which most commonly have spread from tumors located outside the brain ...
Atypical teratoid rhabdoid tumor. An atypical teratoid rhabdoid tumor ( AT/RT) is a rare tumor usually diagnosed in childhood. Although usually a brain tumor, AT/RT can occur anywhere in the central nervous system (CNS), including the spinal cord. About 60% will be in the posterior cranial fossa (particularly the cerebellum ).
A CT or MRI of the pituitary may also show the ACTH-secreting tumor if present. However, in 40% of Cushing's disease patients MRI is unable to detect a tumor. [8] In one study of 261 patients with confirmed pituitary Cushing's disease, only 48% of pituitary lesions were identified using MRI prior to surgery.
A large Canadian community survey revealed that the most common medically unexplained symptoms are musculoskeletal pain, ear, nose, and throat symptoms, abdominal pain and gastrointestinal symptoms, fatigue, and dizziness. [4] The term MUPS can also be used to refer to syndromes whose etiology remains contested, including chronic fatigue ...
Oncology. An adrenal tumor or adrenal mass[ 2] is any benign or malignant neoplasms of the adrenal gland, several of which are notable for their tendency to overproduce endocrine hormones. Adrenal cancer is the presence of malignant adrenal tumors, and includes neuroblastoma, adrenocortical carcinoma and some adrenal pheochromocytomas.
1. Low Libido. While medications, relationship struggles, and illness can all make you lose interest in sex, a low sex drive is one of the most common symptoms of low testosterone. A drastic drop ...
