Can a Large Focal Nodular Hyperplasia Go Undetected on a CT Scan?
I am a 26-year-old woman and I don’t smoke. My question pertains to the visibility of a 6 cm focal nodular hyperplasia (FNH) on a contrast-enhanced CT scan. Could such a sizeable FNH potentially be overlooked during the imaging, or is there a chance that it has vanished entirely?

A 6 cm focal nodular hyperplasia (FNH) is generally large enough to be detected on a contrast-enhanced CT scan, as these nodules typically appear as well-defined lesions with characteristic features. However, the visibility of FNH on imaging can depend on several factors, including the quality of the imaging, the experience of the radiologist, and the specific characteristics of the nodular tissue.
Explanation
FNH is a benign liver lesion often composed of a combination of hepatocytes (liver cells) and fibrous tissue, recognized for its typical appearance on imaging studies. While it’s uncommon for a lesion of this size to go completely undetected, misinterpretation can occur in certain circumstances, such as if there's overlapping pathology or if the imaging study was not ideal.
It’s unlikely that a significant-sized FNH would have 'vanished,' as benign lesions like FNH do not typically resolve on their own. However, it is possible for them to remain stable over time without changes.
Next Steps
-
Follow-Up Imaging: Consider scheduling a follow-up imaging study if you have concerns about whether the FNH was detected. This can help confirm its presence and monitor any changes.
-
Documentation Review: If you have access to past imaging reports, review them for descriptions of the findings. This can provide context on what was previously noted.
-
Monitoring Symptoms: Keep track of any symptoms you may experience, such as abdominal pain or swelling.
-
Education: Educate yourself about FNH and any potential symptoms to stay informed. This aids in understanding when further medical advice may be necessary.
If you have persistent concerns or are experiencing symptoms, additional imaging or a discussion with your healthcare provider may become a priority for clarity and reassurance. Feel free to reach out if you need more information or support.

Understanding Immunoglobulin Levels Over 12 Years
Greetings, I am a 37-year-old woman, weighing 12 stone and standing at 172 cm tall, with no known health issues. I recently received the results from my blood tests, which are as follows: - IgG: 15.1 g/L (within the normal range of 6.0 to 16.0) - IgA: 3.76 g/L (above the normal range of 0.8 to 2.8) - IgM: 1.31 g/L (normal range of 0.5 to 1.9) Upon reviewing my medical history, I noticed that my IgA levels were previously elevated at 3.45 g/L in 2013, yet this was never addressed at the time. I'm seeking clarification on the implications of these findings. It baffles me that my IgA levels have been elevated for over a decade without any intervention and that I do not exhibit any symptoms. Moreover, I have undergone various unrelated tests recently, including a FIT, calprotectin test, abdominal ultrasound, and CT scans for both abdominal and pelvic regions, all of which yielded normal results. What might these immunoglobulin levels signify? Any insights would be greatly appreciated, as I feel quite uncertain about this situation. Thank you!
Strange Odor in My Nose
Age: 18, Gender: Female, Non-smoker, No alcohol consumption, 1 year postpartum. For the past six to seven weeks, I have been feeling quite under the weather. Although I am gradually recovering from a severe case of the flu, I am still experiencing a slightly runny nose and a persistent cough. Due to my health anxiety, I am becoming increasingly concerned that I may have a brain tumor. Lately, I have been encountering an unusual smell that seems to arise suddenly, reminiscent of the odor that occurs if my nose were to be struck. This bizarre sensation has heightened my fear, particularly since I have read that such symptoms might be associated with seizures. I would greatly appreciate any guidance or reassurance regarding my situation.
Understanding Pink or Reddish Urine
Hello everyone on Reddit, both medical professionals and fellow users. I'm a 25-year-old male, and I have a bit of a concerning issue. Just yesterday, I noticed that my urine had taken on a pinkish or red hue, and it has me quite alarmed. It’s strange because just the day before I felt perfectly fine. I'm curious if it could be linked to the bread I consumed yesterday morning or perhaps the hearty laughter from the night before. This situation has been causing me a fair bit of anxiety. I have a doctor's appointment scheduled for July 10th, so I'm planning to wait until then, but I would greatly appreciate any insights or thoughts on what might be causing this change in color.
Unusual Vein Appearance on Left Side of My Neck: Do I Need to Be Concerned?
I’m a 28-year-old female, weighing 143 pounds and standing at 5 feet 6 inches tall, of Asian descent. Earlier today, after completing my workout, I was enjoying a snack while looking in the mirror when I spotted an unusual formation on the left side of my neck, just above the collarbone. I am unsure if this warrants any concern. Although it appears to be peculiar, it doesn’t cause any pain. It feels normal to the touch and there doesn’t seem to be anything abnormal beneath the skin. My last health examination took place in December, and there were no issues noted at that time. I maintain a consistent workout routine, hitting the gym three times a week.
