MRI Findings After Detection of Liver Lesion via Ultrasound
A 38-year-old female recently attended an appointment with her primary care physician, during which she was noted to have traces of blood in her urine and abdominal distension. An ultrasound of her abdomen was carried out incidentally revealing a lesion on her liver, measuring 2.5 cm x 2.5 cm. Due to its size and characteristics, a follow-up MRI was advised for further assessment. I have just received the results and I am puzzled as to why there's a recommendation to wait six months for a follow-up MRI with the preferred contrast agent, especially with the lesion being labeled as 'indeterminate.' I find it difficult to comprehend the rationale behind such a delay. **TECHNIQUE:** Images of the abdomen were obtained using multiplanar T1 and T2-weighted sequences, which included T2 SSFSE, T2 FSE, DWI, along with both in-phase and out-of-phase imaging, plus pre and post-contrast 3D T1-weighted images. IV Elucirem was administered. **FINDINGS:** Upon examination of the liver, multiple T2 hyperintensities were noted, with the largest measuring 2.5 cm located in segment 1, characterized by discontinuous peripheral nodular enhancement and slight filling on the delayed imaging phases. An additional lesion measuring 2.6 cm in segment 6/7 was observed beneath the capsule (1201:39), demonstrating intermediate T2 signal and slightly heterogeneous hyperenhancement during the arterial phase, with this enhancement persisting through the portal venous and delayed imaging phases, not aligning distinctly with blood pool characteristics. **IMPRESSION:** 1. The lesion in segment 6 is identified as hyperenhancing but remains indeterminate, warranting differential diagnoses including hepatocellular adenoma and focal nodular hyperplasia (FNH). A follow-up MRI with Eovist is recommended in six months for further characterization and to verify its stability. 2. The remaining hepatic findings appear consistent with benign hemangiomas.

It's understandable to feel concerned about the MRI findings and the recommendation for follow-up. The delay in scheduling another MRI may seem perplexing, especially with the lesion labeled as 'indeterminate.' However, there's a medical basis for this approach.
Main Points
- Indeterminate Findings: The lesions identified in your liver have characteristics that suggest they could be benign, such as a hepatocellular adenoma or focal nodular hyperplasia, but they need monitoring to determine their nature over time.
- Monitoring for Stability: The six-month wait allows healthcare providers to assess whether the lesions change (grow or shrink) over time, which is vital for accurate diagnosis and reduces unnecessary interventions.
Explanation
- Indeterminate Lesions: Sometimes, imaging shows changes that aren’t clearly benign or malignant, so additional imaging is needed to watch for changes without making hasty conclusions.
- Contrast Use: The specific type of MRI contrast (Eovist) used is particularly helpful for liver imaging to provide clearer information about blood flow and tissue characteristics.
- Benign Characteristics: The impression that some findings are consistent with benign hemangiomas suggests that there’s likely a low risk of malignancy, warranting a conservative approach rather than immediate invasive testing.
Next Steps
- Understand the Follow-up Plan: Know that waiting six months for another MRI is a common practice when lesions are evaluated as indeterminate. This is to ensure accurate diagnosis while minimizing unnecessary procedures.
- Monitor Symptoms: Keep track of any changes in symptoms, like abdominal pain, changes in urine, or overall health. Note any new symptoms in a journal to discuss with your doctor at the next visit, if any occur.
- Maintain a Healthy Lifestyle: Focus on general health through a balanced diet, regular hydration, and avoiding alcohol, which can support liver health.
- Follow Up on Concerns: If you have persistent worries or experience new symptoms during this waiting period, do not hesitate to contact your healthcare provider for advice.
It’s important to communicate your concerns with your physician who can provide support and reassurance as you go through this monitoring phase.

What's Next for My 30-Year-Old Relative on a Ventilator?
On July 9, 2025, my 30-year-old brother-in-law was admitted to the Intensive Care Unit. Before his hospitalization, he was not taking any medication but struggled with alcohol dependence, which has contributed to his poor health. Currently, my boyfriend’s brother is in critical condition, and I’m trying to gather information to help my boyfriend, whose mother is having difficulty formulating direct questions. I feel uneasy about urging him to inquire further, but I’ll provide all the details I currently have. For several years, he has engaged in excessive drinking, leading to severe malnutrition, which has taken a toll on his body. Tragically, on July 16, he aspirated fluid, causing his heart to stop for six minutes. Medical personnel successfully revived him and placed him on a ventilator. Thankfully, he was able to respond to them by squeezing their hands, showing that he understood what was happening. Today, the medical team attempted to reduce his reliance on the ventilator; however, they needed to reactivate it after only 20 minutes. He is receiving two types of nutritional support to address his deficiencies, and surprisingly, the nurses informed me he suffered no fractured ribs from the CPR intervention. Nonetheless, he is extremely weak, and concerns are growing regarding a potential pneumonia diagnosis, although this has yet to be confirmed. The team has indicated that they will attempt to minimize his reliance on the machine again tomorrow. We are now left wondering if it was anticipated that he would require the ventilator again after such a brief attempt at weaning. Was it reasonable to expect that he could breathe without assistance right away, or should we interpret the need for it to be re-engaged as a disheartening sign? While the ultimate aim is for him to breathe independently, what level of optimism should we maintain for an improvement tomorrow? I sympathize with his mother, but her incessant questioning is creating some tension with the care team. I don’t blame the medical staff either; it's evident they are putting in a tremendous effort to restore his health. Thank you for any insights you can share.
Identifying the Issue: Infection or Allergy?
A 36-year-old male, weighing 180 pounds and standing at 5 feet 7 inches, experienced a minor accident two weeks ago that resulted in a small scrape on his arm. Initially, the scraped area scabbed over without issue. However, after going for a swim a week later, the scab came off and the wound began to emit discharge and exhibited redness. Upon consulting a physician, he was prescribed mupirocin, a topical antibiotic cream. Following treatment, there was noticeable improvement with reduced discharge, yet the site remains entirely red and now features numerous blisters. There’s some uncertainty whether this is due to an infection or an allergic response, potentially linked to the adhesive on bandages or the cream itself. To prevent further irritation, he has switched from bandages to gauze secured with tubular netting, but the rash appears to be gradually worsening. During his last visit, the physician provided a prescription for oral antibiotics as a precaution, and he is now contemplating whether to fill this prescription or return to the doctor, especially if the condition is confirmed as an allergy rather than an infection.
Concerns About Ear Discomfort?
I'm a 20-year-old female, standing at 5'4" and weighing 130 lbs. Over the last few days, I've noticed a sensation of fullness in my ears coupled with feelings of fatigue and weakness. Occasionally, I experience some sinus pressure, along with mild, infrequent ear pain and headaches. However, the most troubling symptom is a persistent dizziness that lasts throughout the day (I'm unsure if it could be categorized as vertigo). I consulted with my general practitioner yesterday, who ruled out any infections or blockages due to wax. What could possibly be causing these symptoms?
Persistent Toe Infection in a 27-Year-Old
For several months now, I have been dealing with an infection in my big toe. Initially, I suspected it might be an ingrown toenail, but after attempting to remedy the issue by removing the nail several times, the infection persists. The area is quite tender, exhibits a purple hue, and tends to bleed excessively. If anyone would like to take a closer look or offer advice, please drop a comment, and I can send a direct message with an image since this subreddit does not permit posting photos.
Severe Discomfort in the Back and Breathing Difficulties
I experience intense pain located between my left shoulder and spine. The discomfort can be so acute that any sudden movements or twists can cause me to gasp involuntarily, making it nearly impossible to take deep breaths. Coughing intensifies the pain to the point of being almost unbearable. In previous instances, I've found it challenging to sit upright, often needing to roll over and hold my breath just to cope with the agony. I have not suffered any past injuries to my back. As a software developer, I wonder if this could be related to my posture. I suspect it may be due to a pinched nerve, although I am not a medical professional. My first concern is to know when it would be appropriate for me to consult a physician regarding this matter. Additionally, I'm interested in exploring potential remedies, such as strengthening exercises for my back or incorporating regular stretching and massage into my routine to alleviate these issues.
