Uncovering the Mystery of a Multilocular Liver Cyst: Evaluating Stable Yet Varied Measurements
I have a multilocular cyst on my liver, which may potentially stem from a serious car accident I suffered two decades ago, although this hasn't been definitively confirmed. Medical advice I received suggested either monitoring the cyst through periodic MRIs, on an annual or biannual basis, or opting for surgical intervention. Since 2022, I've undergone four MRI scans. The latest two scans were conducted two years apart, and while the most recent report indicates stability and includes the dimensions of the cyst, these measurements do not align with the previous ones; they suggest an increase in size instead. In light of this, I have a couple of questions: 1. Could the differences in size be attributed to the radiologist’s measurement methods, or should I consider seeking a second opinion with all prior imaging? 2. While the term "stable" is reassuring, I am uncertain about how to interpret the potential growth noted in my reports. Here’s the summary of my liver reports: **April 4, 2022** - The liver appears to be of normal size. Out-of-phase imaging shows a significant decrease in signal intensity, consistent with extensive fatty liver disease (hepatic steatosis). Notably, there exists a complex multiloculated cyst in segment 5 of the right lobe measuring 5.1 x 3.9 x 3.8 cm, accompanied by mural calcifications. No nodular enhancements or signs of edema or inflammation in the adjacent areas are observed. **April 9, 2022** - Normal liver morphology is noted alongside diffuse hepatic steatosis. The previously identified multiloculated cystic lesion in segment V measures approximately 4.9 x 3.8 x 3.8 cm, slightly down from the earlier measurement of 5.1 x 3.9 x 3.8 cm, indicating no significant change. The cyst shows mural calcifications, more visible in previous CT scans, with no nodular enhancements associated. **September 18, 2023** - The liver size remains normal, with diffuse signal loss evident in out-of-phase imaging consistent with fatty liver disease. A multiloculated cystic lesion sizes at approximately 4.6 x 4.3 cm in the right hepatic lobe, exhibiting similar rim enhancement as seen before. No distinct nodular enhancements are apparent. **September 25, 2025** - The liver is still exhibiting signs of hepatic steatosis. The lobular multiloculated cyst in hepatic segment 5 (series 106, image 28) shows intrinsic T1 hyperintensity, suggesting it may contain hemorrhagic or proteinaceous material. Its dimensions are now 6.6 x 4.4 x 4 cm compared to 6.6 x 5 x 3.8 cm recorded using similar methodologies previously. No internal enhancements are detected, although a stable thin peripheral rim enhancement remains. The shifts in these measurements have left me with questions regarding the monitoring of my cyst and the implications of its alleged growth despite stability reports.

It's understandable to be concerned about the changes in your multilocular liver cyst, especially given the long time you've been monitoring it and the fluctuations in reported measurements. Let’s break down your questions and the implications of your imaging results.
Main Points:
- Measurement discrepancies may arise from different radiologist techniques, but these discrepancies should be assessed carefully.
- The term “stable” refers to the general appearance and lack of new concerning features, but any growth should be monitored closely.
Explanation:
- Measurement Variability: Differences in size can commonly occur due to variations in measurement techniques between different radiologists, changes in imaging angles, or even slight differences in positioning during scans. Radiologists can also have varying interpretations of cyst characteristics. Given that they are reporting stability in terms of no new features (like nodules or signs of inflammation), this is generally a good sign.
- Understanding "Stable": When a cyst is termed “stable,” it typically means that there are no new alarming changes that suggest cancer or significant complications. However, if measurements indicate any growth, particularly in the context of your history and symptoms, it's essential to take it seriously. Growth can imply possible changes in the cyst's contents or characteristics that warrant further evaluation.
Next Steps:
-
Seek a Second Opinion: Considering the complexity of your case and the varying measurements, obtaining a second opinion, ideally from a hepatologist or a specialized radiologist, can provide clarity. Bring all your previous imaging studies for reference. This can confirm whether the measured growth is significant or possibly a measurement artifact.
-
Monitoring Approach: Continue your regular follow-up schedule. Given that the cyst is currently being monitored, discuss with your healthcare provider if it is appropriate to continue annual imaging or if biannual scans would be more suitable based on current findings.
-
Symptom Awareness: Keep monitoring for any symptoms such as abdominal pain, discomfort, or any new changes in your health. If you notice any concerning symptoms, report them immediately to your healthcare provider.
-
Lifestyle Adjustments: Since you have fatty liver disease noted in your scans, consider making lifestyle changes that can help improve your liver health, such as maintaining a balanced diet low in fats and sugars, staying active, and avoiding alcohol.
-
Document Your Concerns: Create a document summarizing your concerns, recent imaging results, and any questions for your next appointment with a healthcare provider. This can ensure a thorough discussion and address your specific worries.
By staying informed and actively managing your health, you can navigate this complex situation with greater peace of mind. Feel free to reach out with any further questions or updates!

Experiencing Clear Fluid from Ear with No Discomfort: Should I Wait for My Appointment?
I am a healthy 57-year-old female, weighing 120 pounds and standing 5 feet 5 inches tall. My daily medications include 100 mg of Losartan for effectively managed high blood pressure, 200 mg of Lyrica taken twice daily for post-herpetic neuralgia, 100 mg of Synthroid following treatment for thyroid cancer, and a combination hormone replacement therapy patch. Additionally, I take Zyrtec and Flonase every day to combat allergies. Since October, I have been dealing with persistent tinnitus in my right ear, accompanied by some pressure and a muffled sensation. Recently, I've noticed that when I speak, it feels akin to the sensation I experience when my ears clear during a flight after chewing gum—my voice sounds amplified in my head. I've scheduled an appointment with a physician's assistant in an ear, nose, and throat (ENT) office for the end of March due to my worries about the tinnitus and any potential hearing impairment. Yesterday, I noticed that my ear emitted a clear fluid. Thankfully, there was no associated pain. The fluid was somewhat thicker than water, completely odorless—unlike the unpleasant discharge I recall from my daughter's ear infections—and there was no sign of blood. Could this indicate a perforated eardrum? I suspect this might be the case, but can this occur without an underlying infection? Should I seek attention sooner than my appointment in March? I would prefer to avoid urgent care during flu season; however, if this situation is serious, I am prepared to take precautions and visit.
Understanding the Increased Pain in My Foot While Reclining
At 30 years old, I am nearing the five-week mark since undergoing surgery on my metatarsals. I've encountered a troubling issue: I can’t seem to find comfort when lying down, whether it’s with my foot raised or lying flat. My pain level escalates to a severe 10 out of 10, unless my foot is making contact with the floor or I dangle my leg off the side of the bed so that my toes touch the ground. Is this situation typical for someone in my circumstances? Are there any suggestions that might assist me in getting a better night's sleep?
Assessing My Health Concerns: How Anxious Should I Be?
I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.
Understanding Possible Seizure Triggers and Recurrence Risks
Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!
Persistent Pain in Right Shoulder and Arm After Lifting
Hello, everyone! I’m a 23-year-old male and have been engaged in weightlifting for several years now. Recently, I’ve been struggling with ongoing discomfort in my right shoulder and arm, which I haven’t been able to accurately identify. The pain manifests during particular movements, especially with lateral raises or when my arm is raised to shoulder level while rotating my wrist. Certain pressing and pulling activities can also provoke this discomfort. Rather than feeling sharp, it’s a deep, nagging sensation that sometimes seems localized in the front area of the shoulder or at the biceps tendon, and at other times it feels more like it’s situated between the shoulder and upper arm. Fortunately, there’s no numbness or tingling involved. This issue began while I was working out. I decided to take a break for around two months, but when I returned, the pain persisted. After consulting a physician, I was diagnosed with bicipital tendinitis. Since then, I’ve reduced my upper-body workouts, completely steering clear of shoulder exercises and heavy lifting, and have begun a gentle rehabilitation regimen focusing on external rotations, pendulum movements, and scapular exercises. Despite adhering to this routine for about a week, I haven’t experienced any noticeable improvement. Is it typical for this type of tendon injury to require an extended period for recovery? At what point should I consider diagnostic imaging, such as an ultrasound or MRI? Additionally, are there frequent rehabilitation errors that might impede the healing process? I appreciate your insights in advance!
