Visual field defect and magnetic resonance imaging (MRI) revealed a pituitary adenoma causing severe compression of the left optic chiasm. Prompt neuro-ophthalmological intervention and subsequent pituitary tumor resection were crucial for optimal patient outcomes. Follow-up assessments demonstrated improved ...
By definition, a microadenoma (seen in the image below) is a tumor less than 10 mm in diameter. Pituitary adenomas may secrete hormones, but most are clinically inactive. (It should be noted that in 2021, the World Health Organization [WHO] adopted the term “pituitary neuroendocrine tumor”...
“...striking clinical effects might be produced by minute, symptomatically predictable (pituitary) adenomas. So, it is the degree of secretory activity of an adenoma, which may be out of all proportion to its dimension, that evokes the recognizable symptom complex in all hypersecretory states....
Causes and symptoms The cause of pituitary tumors is not known, but may be genetic. Symptoms related to tumor location, size, and pressure on neighboring structures include: persistentheadacheon one or both sides, or in the center of the forehead ...
multiple endocrine neoplasia type 1 and type 4, Carney complex, pheochromocytoma/paraganglioma and pituitary adenoma and pituitary blastoma, as well as on familial isolated pituitary adenoma (FIPA) conditions associated with AIP or GPR101 mutations and other rare causes of pituitary hormones ...
The pituitary macroadenoma, defined as a tumor more than 10 mm in diameter, can compress adjoining structures within the sella turcica and enlarge into surrounding areas, leading to signs and symptoms with complications, visible disturbances, and hyperpituitarism. In this case, the patient ...
The disease is caused by chronic growth hormone and insulin-like growth factor 1 secretion from a pituitary somatotrope adenoma that forms before the closure of the epiphyses. If not controlled effectively, this hormonal hypersecretion could lead to extremely elevated final adult height. The past ...
tumor suppression and have been a target of interest for drug development for several decades. Most drug development efforts have focused on controlling hormone production by a functioning pituitary adenoma. One of the most studied diseases is acromegaly, a condition resulting from exce...
In this Review, the authors discuss the clinical features of patients with sporadic pituitary adenomas that are associated withAIP or MEN1mutations, and discuss the molecular mechanisms potentially involved in pituitary adenoma tumorigenesis. They also d
