Presentation
Left thigh pain.
Patient Data



Multiple lytic mildly expansile lesions in the proximal phalanx of the 1st, 2nd and 3rd toes showing thinned overlying intact cortex, narrow transition zones and normal surrounding bone matrix. No definite underlying fractures could be identified, consistent with multiple enchondromas.

Subtle medulla lucency at the proximal diaphysis of the left femur.





Bilateral intramedullary hyperdense lesions along the diaphysis of both femora with chondroid matrix calcifications.













Multiple ill-defined intra-medullary focal bony lesions noted involving the left femoral shaft, the largest is seen at distal half of the left femoral shaft, expressing heterogeneous T1 hypointense, T2 and T2 fat sat hyperintense signal.







Another similar but smaller lesion is noted at the proximal left femoral shaft, showing the same previously mentioned signal characters
The right thigh showed another similar lesion at the proximal right femoral shaft.
Case Discussion
Bilateral multicentric femoral focal bone lesions, pathologically proven enchondromas.
The presence of other lesions at other parts of the skeleton is consistent with Ollier disease.
