Seeking Insights on My Son's Unicameral Bone Cyst
I'm reaching out for thoughts regarding my seven-year-old boy, who has been diagnosed with a 5.8 cm unicameral bone cyst (UBC) located in the neck of his left femur. The doctors have recommended immediate surgical intervention due to a minor fracture and the associated weakening of the bone. The proposed procedure involves placing a plate and two screws, with an estimated recovery time of six to eight weeks, during which he would need to relearn walking. Additionally, there might be a necessity for ongoing injections if the cyst recurs. I appreciate any insights or advice you may have on this situation, as I realize these cases can be quite complex. Given the location of the cyst on the bone neck, there are concerns over the pressures from walking and running, which is why the medical team aims to strengthen the bone to prevent further fractures. Thank you for any perspectives you can share.

It sounds like your son is facing a significant medical situation with the unicameral bone cyst (UBC) in his femur, and I understand this can be very concerning for you. The decision for surgical intervention to strengthen the bone is aimed at preventing further issues, especially given the fracture you've mentioned.
Key Points:
- Surgery is recommended due to the cyst's size and the fracture, to prevent further complications.
- The recovery period includes relearning how to walk, but with appropriate care, kids often adapt well.
Explanation: A unicameral bone cyst is a fluid-filled cavity within the bone, typically benign but can cause weakness and increase the risk of fractures. In your son’s case, the cyst's location and the presence of a fracture indicate that the bone needs additional support to ensure safety as he grows and becomes more active.
Surgical intervention often involves:
- Removing the cyst material.
- Supporting the bone with a plate and screws to restore strength and stability.
- This is critical to prevent future fractures, especially in a weight-bearing bone like the femur.
The recovery timeline means he may need help transitioning back to normal activities, but children are generally adaptable. The ongoing potential need for injections is common in cases of recurrences and can help manage the cyst effectively.
Next Steps:
-
Follow Through with Surgery: Proceed with the scheduled surgical plan as it is a well-established approach to manage this condition and reduces future fracture risk.
-
Monitor Recovery: Post-surgery, focus on supporting your son during his recovery. This includes:
- Encouraging rest and adherence to rehabilitation exercises as advised by your medical team.
- Help facilitate a safe environment for him while he is relearning to walk.
-
Stay Informed: Keep open communication with his medical team. Ask about:
- The specific rehabilitation plan for post-surgery care.
- Signs of recurrence to watch for in the future.
-
Emotional Support: It’s essential to reassure your son throughout this process. Engage in activities he enjoys that don’t require intensive physical exertion while he recovers.

Liver Enlargement and Abdominal Drainage Insights
A 42-year-old woman, who does not smoke and has a history of significant alcohol consumption spanning two decades, has recently gone through a medical procedure involving abdominal drainage after being diagnosed with liver enlargement. Following the procedure, which removed approximately 2.6 liters of fluid, she immediately felt a change. However, she is currently experiencing some residual bloating and finds it difficult to wear her usual pants comfortably. It's been nearly a week since the drainage, and she is curious about the typical recovery timeline. She wonders if this sensation is standard and whether additional drainage sessions might be necessary. With no alcohol consumed in the last three weeks and a commitment to abstaining further, she is looking forward to her follow-up appointment in two weeks to discuss her progress. Any advice from others who may have faced a similar situation would be greatly appreciated. 🙏🏻
Could These Symptoms Indicate Ovarian Cancer?
A 31-year-old female shares her health concerns. Last year, from September until mid-December, she was pregnant and underwent several pelvic ultrasounds during that period. Since January, she has noticed an increased frequency in urination that involves larger amounts, not just small quantities. Although she has undergone urine and kidney evaluations, the results have returned normal. In May, she began experiencing constipation that is unusually persistent for her, as she has not traditionally faced such extended issues in this area. During a consultation with her doctor in late May, she was prescribed Sennokot to use as needed. She wonders if her symptoms could potentially align with ovarian cancer, and if such a condition might manifest this rapidly despite previous imaging showing only peripheral follicles, particularly given her PCOS diagnosis with eight follicles present last fall.
What Might Be Causing My Baby's Swollen Finger?
Hello fellow parents and healthcare professionals! I’ve observed some unexpected swelling on my two-year-old's finger, and I'm seeking your advice. There's no visible injury that I can identify. - The swelling appeared just the day before yesterday. - Sometimes my little one seems perfectly fine, but there are moments when he expresses discomfort and cries. I’ve been giving him paracetamol to help ease his pain. - Importantly, he doesn’t have a fever and shows no other concerning symptoms. Has anyone encountered a similar situation? What could lead to such localized swelling? Should I consider taking him to urgent care immediately, or would it be okay to wait until his pediatric appointment? Any guidance would be greatly appreciated!
Unexplained Rash on Back
Greetings! I'm a 30-year-old woman, and I discovered a hive-like mark on my back about the size of a quarter six days ago. Initially, I might not have noticed it, but when I rolled over in bed, the movement caused it to pinch, resulting in quite a bit of pain. I hadn't engaged in any unusual activities or experienced anything out of the ordinary that could have triggered this reaction. Three days later, I checked the area and realized it was still red but appeared flatter. Now, after six days, the mark remains. It has become a bit more splotchy but is still quite evident. While it was painful on that first day, it hasn’t caused me any discomfort since, nor has it been itchy. I do have conditions such as POTS and EDS, but I'm unsure if they play a role here. I'm contemplating whether I should consult my primary care physician about this issue or if it can simply be considered an unusual reaction that isn't a cause for concern. Thank you for your assistance!
Concerns Over Persistent Swollen Lymph Nodes
Last March, a CT scan revealed that my lymph nodes were slightly enlarged. Come September, an ultrasound confirmed the presence of three lymph nodes, one of which was noted for its notable size and a cortical thickening of 0.5 cm, prompting a follow-up scan in six months. The recent scan this year has now identified 12 lymph nodes, several of which exhibit cortical thickening measuring between 3 to 5 mm. In contrast to last year's findings, where only one lymph node showed any thickening, one current lymph node is described as having a vague fatty hilum. Despite being categorized as "mildly reactive," these lymph nodes have persisted for over a year, increasing in both size and quantity, yet no follow-up has been advised. Should I be worried? To date, I have not experienced any recent infections or illnesses, and my lab results appear normal. However, I have endured a troubling 30-pound weight loss without explanation, bouts of sweating, episodes of dizziness or faintness, and recurring fevers ranging from 99 to 104 degrees that have persisted for a year. **Lymph Node Measurements (in centimeters):** 1. 1.0 x 0.9 x 0.4 cm - Located posterior to the right sternocleidomastoid (SCM), just above the hyoid with a vague fatty hilum. 2. 1.3 x 1.0 x 0.8 cm - Found anterior to the right SCM, above the hyoid featuring 3 mm of cortical thickening. 3. 2.9 x 2.7 x 0.7 cm - Situated anterior to the right SCM, above the hyoid, noted as the largest lymph node with 4 mm cortical thickening. 4. 1.0 x 0.8 x 0.2 cm - Positioned posterior to the left SCM, above the hyoid. 5. 1.7 x 1.1 x 0.3 cm - Located posterior to the left SCM, above the hyoid (potentially comparable to the earlier measurement of 1.4 x 0.9 x 0.2 cm). 6. 0.4 x 0.4 x 0.2 cm - Found posterior to the left SCM, beneath the hyoid. 7. 1.2 x 1.1 x 0.6 cm - Side not specified, though likely to be on the left, featuring 3 mm cortical thickening. 8. Size not detailed in report, presumed to be similar to the previous scan - 5 mm cortical thickening. 9. 1.9 x 1.0 x 0.7 cm - Located anterior to the left SCM, above the hyoid. 10. 1.3 x 0.7 x 0.2 cm - Found anterior to the left SCM, below the hyoid. 11. 1.7 x 0.9 x 0.7 cm - Located within the right submental region showing 4 mm cortical thickening. 12. 1.2 x 0.9 x 0.6 cm - Found in the left submental region with 3 mm cortical thickening. **IMPRESSION:** The examination reported that bilateral cervical lymph nodes are largely within acceptable size limits based on short-axis measurements. Nonetheless, several nodes show mild cortical thickening, indicating slight reactive changes. The radiologist did not suggest any follow-up actions, which raises my concerns. With the lymph nodes swollen for such a prolonged period without any signs of illness, infection, or inflammation, I find it troubling. My lab tests show no inflammation markers, with ESR and CRP levels returning normal. New lymph nodes continue to emerge. I'm aware that "reactive" typically implies eventual shrinkage, yet mine have not diminished at all. Am I justified in my worries?
