Possibilities they threw out there:
- Leukemia - don't think so. She's not even sick!
- LCPD - Legg Calve Perthes Disease. This seems like a possibility, especially because it's showing up at the lower ends of both of her femur bones. (the growing ends, as the article says.) Here's a better overview right here
Background
Legg-Calvé-Perthes disease (LCPD) is the name given to idiopathic osteonecrosis of the capital femoral epiphysis of the femoral head. The goal of treatment is to avoid severe degenerative arthritis.
Pathophysiology
The capital femoral epiphysis always is involved. In 15-20% of patients with LCPD, involvement is bilateral.
Frequency
United States
One in 1200 children younger than 15 years is affected by LCPD.
Mortality/Morbidity
LCPD is a self-limited disease if not treated.
Outcome is extremely variable.
Race
Caucasians are affected more frequently than persons of other races.
Sex
Males are affected 4-5 times more often than females.
Age
LCPD most commonly is seen in persons aged 3-12 years, with a median age of 7 years.
Clinical History
Symptoms of Legg-Calv é -Perthes disease usually have been present for weeks because the child often does not complain.
- Hip or groin pain, which may be referred to the thigh
- Mild or intermittent pain in anterior thigh or knee
- Limp
- Usually no history of trauma
This sounds like a possibility to me, which I have to say is an EXTREMELY GOOD THOUGHT. If you click the 'treatment' link at the bottom of the page, it seems like the treatment is for pain only and she'll grow out of the actual disease.
*taps foot* I'm keeping my fingers crossed. She seems to fit right into the demographic.
She'll have more blood work done today and then a bone biopsy tomorrow. Poor little gal. We're all on pins and needles to find the real diagnosis.
