Ollier disease

Case contributed by Dr Mostafa El-Feky


Left thigh pain.

Patient Data

Age: 30 years
Gender: Female

Left foot

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.


Both thighs

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


Both thigh

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.
