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.

Interpretation Request for Recent Spinal NM Bone Scan
Hello, doctors. I'm reaching out for your insights regarding a recent NM bone scan of my spine. I've previously undergone a similar scan in 2022, and I'd like to compare the two. To provide context, I am a 29-year-old female weighing 100 kg, and I've been diagnosed with conditions including endplate sclerosis, spinal stenosis, cervical bone spurs, degenerative disc disease (DDD), and mild scoliosis. My medication regimen consists of several prescriptions. Unfortunately, my next appointment with my general practitioner is still a few weeks away, so I would appreciate your assessments on how the latest scan compares to the previous one. Thank you in advance for your help!
Unexpected Eye Issues: Headache and Double Vision Concerns
A 33-year-old female, measuring 1.67 meters in height and weighing 55 kilograms, residing in the Netherlands, experienced a sudden onset of symptoms. Last evening, shortly after dinner, my partner complained of a slight headache localized at the rear of her head. Along with this discomfort, she encountered double vision and noticed her right eye deviating outward. Interestingly, when she shut either eye, the double vision resolved, enabling her to see without distortion. We rushed her to the emergency room later that night. The medical team conducted a variety of assessments, including physical examinations, neurological evaluations, visual tests, and laboratory analyses. Fortunately, all results were normal. However, the doctors found it peculiar that her right eye exhibited normal movement and accurately tracked a pen in all directions when her left eye was closed. The medical opinion suggested that it may be a migraine-related episode, a condition she has experienced previously. Nonetheless, she insists that this feels unlike any migraine she has had in the past. A teleconsultation with a neurologist is scheduled for Monday to arrange an MRI should the symptoms continue. The doctors advised that if her symptoms worsen, we should return to the hospital immediately. Fortunately, after a night's rest, her vision had returned to normal by morning, the headache had subsided, and her right eye was aligned properly. I am understandably concerned, particularly due to her assertion that this does not resemble a typical migraine. Is it possible that this is indeed a migraine, or could it be indicative of another underlying issue? Thank you for your attention to this matter.

Persistent Need to Stretch Legs While Seated
I experience a significant discomfort when seated, particularly when my knees are bent at about a 90-degree angle. This sensation compels me to stretch my legs straight, and if too much time passes without doing so—typically around every five to six minutes—the urge intensifies to an uncomfortable level that’s hard to manage. It’s more than just a desire to fidget; fully extending my legs tends to offer the greatest relief. Adjusting my position provides some comfort, but it doesn’t alleviate the feeling nearly as effectively as a full stretch does. This issue predominantly arises when I remain stationary in a chair. Occasionally, I notice a similar feeling when I’m lying down, but these instances are relatively rare compared to the frequent occurrences while sitting. I consulted a relative who is a medical professional about this discomfort, and they suggested that it doesn’t appear to align with Restless Leg Syndrome. However, since this isn't their specialization, I acknowledge that there may be a chance of error. * What could potentially be causing these sensations? * Does anyone else relate to this experience? * Are there methods available to help manage or diminish this feeling? I would greatly appreciate any advice or insights.
