Is It Possible That An Mri With Contrast Could Miss A Pituitary Tumor
Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
Yes: Most pituitary tumors are "microadenomas", meaning that they are less than 1 CM in size. Mris done specifically to look for a pituitary tumor are very good at detecting tumors near 1 CM in size, and identify about 50% of tumors in the 0.3 CM size range, and would miss most tumors smaller than this. ...Read moreSee 1 more doctor answer
Having MRI to check pituitary tumor growth.Had coiling of aneurysm 3 months ago.Worried the coils could move because of vibration of the scan?Thanks.
Unlikely: If your physician ordered a brain MRI to look for a pituitary tumor due to symptoms that you reported, then the radiologist would specifically look for one. Thus, it is unlikely. If you're concerned, you can have your physician take a look at the CD of the brain MRI for a second opinion. http://radiopaedia.org/articles/pituitary-mri-an-approach ...Read moreSee 1 more doctor answer
No: A pituitary tumor or adenoma is associated with Cushing's disease when condition has several changes in the body secondary to hormonal disorder caused by prolonged exposure to the cortisol. It produces masculinizing effects and eventual humping of the back with frequent emotional changes. It has been associated with long-term use of corticosteroid, an adrenal tumor or pituitary lesion. ...Read more
It depends: If the tumor produces an excess of acth which is a hormone you may develop all or part of cushing's syndrome. If the tumor is not producing hormones you may not. There are simple blood tests which will help to answer your question. See an endocrinologist or a neurologist for appropriate work up and treatment options. ...Read more
At what size should a pituitary tumor be removed? In Feb it was 4.2x4.3. New MRI Tues. If it's reached a 5 neurologist said to see neurosurgeon? Y/N??
Pituitary adenoma: Yes. See a neurosurgeon who specializes in pituitary surgery to discuss the treatment options. Hormone studies and a visual field examination are part of the evaluation too. Indications for surgery include increasing size of the adenoma, visual field loss and reduction in hormone function due to tumor compression. ...Read moreSee 1 more doctor answer
212 IGF-1 (191);repeat 218; no SX acromegaly but recently diagnosed with cardiomyopathy; coincidental or should I get MRI to rule out pituitary tumor?
NO PITUITARY MRI!: Hi. Those IGF-1's would be normal for a 55 yo woman. Cardiomyopathy has a million and one causes, and acromegaly is WAY DOWN the list of likely causes. Pituitary is classic for "incidentalomas" - masses found incidentally, most of which have no bearing on disease. So you have NO biochemical evidence of acromegaly. Whatcha gonna do if a pituitary tumor IS found? Send a surgeon in??? I hope not! ...Read more
"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
