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 more
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.
Check with neurosurg: The concern with mris and aneurysm coils is whether or not they have MRI compatible metal. Generally, the coils that are currently used (at least in the United States) are all MRI compatible. You should check with your neuro-interventionalist or neurosurgeon who placed the coils. Generally the vibration of the MRI is not enough to move the coils. ...Read more
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 more
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 more
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
I am going for a MRI head scan as I'm suspected to have a pituitary tumor. Will they test for all brain abnormalities or only this?
The MRI head scan should cover everything, unless your provider asked specifically not to.
Sometimes the MRI focuses on the pituitary region only, but many times a full brain screening exam is done with the pituitary scan, so if there is anything else happening, this test will probably help. ...Read more
I feel I have the symptoms of high prolactin (pituitary tumor) but on the blood test for prolactin is normal I haven't done the CT or MRI scan yet?
What is the symptom?: You have to explain, what are the symptoms. ...Read more
What could cause a pituitary tumor (less enhancing) to grow from. 7mm to. 9mm, largest dim, in 2 years, then shrink to. 6mm w/i 5 years? If nonfunctional, would you continue to follow w/ mris?
It depends: It depends on the tumor type and if any medication was taken. You will need to follow with a neurosurgeon to keep an eye on the tumor. If it stays small and doesn't cause any symptoms (e.g. Visual field loss), your surgeon may decide to just follow it with serial mris. Don't forget, every surgical procedure carries risk. ...Read more
Can a pituitary tumor disappear on its own without any treatment? I underwent 2 mris with a contrast. The first showed 5 mm pituitary microadenoma. The second, which was done 3 years later showed no tumor at all. Could it be that a radiologist misread th
MRI: Mri machines can vary greatly in quality and in their ability to distinguish a very small lesion in the pituitary gland. Most microadenomas show up as small areas of decreased enhancement compared to the rest of the gland. These small areas can also be artifact, cyst, scar etc. It is possible but unlikely that the radiologist misread the scan. Finally, most microadenomas are biologically active and produce a hormone. Without an endocrine abnormality, the lesion is less likely to be a microadenoma. When there is doubt clinically, a follow up scan in a few months is advised. ...Read more
My bf has a pituitary tumor that has caused him to gain weight and have mood swings is this all from the. Tumor how do they treat it could he die?
Unlikely: Mood disorders and weight gain are common problems with or without pituitary disease. Pituitary tumors are rarely dangerous or deadly and are usually fairly easy to manage or even cure. His hormone levels need to be carefully monitored, and he needs good followup to monitor the growth of the tumor. His mood and overeating should be treated separately. ...Read more
If you have a pituitory problem you should be guided by an endocrinologist.
Most pituitory tumors are benign and can removed surgically in case the tumor is causing symptoms due to its large size. Some produce excess of hormones, others are non functional. ...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
