AS Jakola,S Gulati 摘要: Introduction Idiopathic intracranial hypertension (IIH) is a clinical condition without a clear underlying condition, although several mechanisms have been proposed over the years [ 11 ]. It is defined as elevated cerebrospinal fluid (CSF) pressure with normal CSF ...
Furthermore, we will give the context of what is known about the background of vaccine allergy and propose and provide an understanding of the classification and mechanisms of allergic reactions associated with the COVID-19 vaccines. We will synthesize the known information to provide a risk-...
The patient then underwent proton beam radiation to the area of concern involving the sella. Prolactin thereafter improved to 44 ng/ml. He then developed acute vision loss of the right eye with an MRI showing tumor in the right cavernous sinus. A 15 mm dural-based right temporal mass ...
MRI brain showed 1.9 cm macroadenoma in the sella. She underwent transsphenoidal resection. Histology confirmed an ACTH-secreting tumor without atypical features: Ki67 <3%, P53 negative. Postoperatively, serum cortisol levels remained elevated to as high as 23.1 μg/dl. In the subsequent weeks ...
while hypogonadism due to testicular origin was reported in others.41–44 Some studies describe a 63% frequency of pituitary abnormalities visible by MRI (pituitary hypoplasia, empty sella, Rathke's cyst, enlarged pituitary gland) accompanied by hormonal imbalances in 45% of the cases (hyperprolactin...

The pituitary gland lies at the middle of the base of the skull and is housed within a bony structure called the sella turcica, which is behind the nose and immediately beneath the hypothalamus. The pituitary gland is attached to the hypothalamus by a stalk composed of neuronal axons and the...
Magnetic resonance Imaging (MRI) is indicated in equivocal cases where excluding other diagnosis is critical and would alter management. The most characteristic MRI findings in GBS are smooth contrast enhancement of the spinal nerve roots with variable thickening, particularly in the cauda equina region...
