CASE 4 ANSWER

Osteopetrosis


Diffusely increased bone density is noted, leading to loss of corticomedullary differentiation. The metadiaphysis is widened (yellow arrow), there are diaphyseal lucent lines (red arrow), and there is a pathologic fibular fracture (circles)



Key Points

  • Genetic disease of imbalanced bone formation and resorption

  • Characteristic imaging feature: Increased bone density, loss of corticomedullary differentiation, leucent bone bands, widened metadiaphysis.

  • A cause of Erlenmeyer flask deformity, along with storage diseases, chronic anemias, and other bone dysplasias.
