I have white spots on my lungs. My doctor does not know what they are. I went and had a ct-scan today. Hoping to know the results friday.?

Wait for CT.: Your doctor probably has a pretty good idea what they are and what they are not likely to be. Ct will be very informative and perhaps definitive. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

I have had spots on my lung since 2004, 2007, 2010 x-rays and 2012 CT scan showed they are slightly larger now. What are the possible diagnoses?

Many: First thing is histoplasmsis. This causes multiple small nodules. It sounds like your doctor is following this: http://www.Med.Umich.Edu/rad/res/fleischner-nodule.Htm which is the best way to follow these nodules. Hopefull, you've quit (or never were) smoking, and you're keeping a very good eye on them. ...Read more

Ct scan showed that I have a 6cm spot/growth on the lower lobe of my right lung. Healthy 40yr old non-smoke fem. Is that large? How common is this?

Ct scan showed that I have a 6cm spot/growth on the lower lobe of my right lung.  Healthy 40yr old non-smoke fem.  Is that large?  How common is this?

6cm=big; 6mm=small: Sometimes people have a 6 mm spot (about 1/4 of an inch wide) but mistakenly remember it as a 6 CM mass (about 2-1/4 inches wide). A mass 6 centimeters (cm) wide is pretty big (a tennis ball is about 6-1/2 cm) and is usually not called a "spot". The doctor who ordered the ct can review the results to confirm whether the finding is a little 6 millimeter (mm) spot or a bigger mass. ...Read more

Ct scan of pelvic abdomen showed 7mm lung spot on lower left lung dr now ordered a chest CT scan wondering why ?

To see the rest of: ...Your lungs. The abdominal study only shows about a third of your lungs. Your doc will need to see the rest to know what to do. Lung nodules are very common and the vast majority are benign scar(s). Most of the time we just use the ct to follow and make sure there is no growth. There are other tests (pet scan for example) that can be useful when there is concern for cancer. ...Read more

Recent (2 days ago) hard hit to the head. Ct scan clear. Getting sharpish pain in a few isolated spots in my head that comes and goes. Major issue?

Monitor closely: The sharp pains at the site of head trauma may be due to mechanical injury to the skull and scalp tissue damage. If your symptoms don't resolve, get worse, or if you have any new neurological deficits, then see your physician immediately. http://www.brainline.org/content/2008/12/headaches-after-head-injuries-8212-post-traumatic-headaches.html ...Read more

I recently had a CT scan and they found spots on my liver, what could this be.Having another CT scan w/contrast next week?

It depends: It depends on several things. The most important considerations are age, sex, and other medical problems. In broad terms, these spots could be anything from cysts to hemangiomas (abnormal, non-cancerous blood vessel accumulations) to cancerous tumors. The ct scan should help clarify. Sometimes a biopsy is necessary to confirm the diagnosis if the ct is unclear. ...Read more

Getting numb,tingling,crawling feeling in my whole face in different spots CT scan was good doctor was no help what causes this should I worry?

Getting numb,tingling,crawling feeling in my whole face in different spots CT scan was good doctor was no help what causes this should I worry?

Many possibilities: Numb, tingling sensations are called "paresthesias" and should be evaluated with a complete neurological exam and history in-person. If the rest of the neurological exam were normal and healthy, the most likely explanations are anxiety, medication side effects, or migraines. Sometimes people can have the sensory auras associated with migraines without having a headache ("acephalgic"). ...Read more

What are neurologists looking for in a 72 hour eeg. He saw three white places in a CT scan. To me these spots looked like the skull. White.

What are neurologists looking for in a 72  hour eeg.  He saw  three white places in  a CT scan.  To me these  spots looked like the skull.  White.

Short lived events: An eeg is only able to capture events that occur while the leads are attached. Ambulatory eegs allow longer-term monitoring to capture these infrequent events more reliably. One typical application is spells that might be seizures- if the eeg during a typical spell does not show seizure activity, that argues strongly for another cause. ...Read more

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
