ABSTRACT

Diagnosis: Endochondroma

History: 26 y/o AD USMC female currently being treated for stress fractures in bilateral lower extremities R > L. A bone scan suggested a mild increased radiopharmaceutical uptake in the proximal tibial diaphysis, not suggestive of a stress fracture, besides the visualized stress fractures.

Findings: Lateral radiographs of the right tibia shows a well-defined lytic mass with stippled calcifications without endosteal scalloping. Coronal STIR image of the proximal tibia shows a high-signal-intensity lobulated diaphyseal medullary mass with focal areas of low signal intensity corresponding the stippled calcifications on the plain radiographs These findings are consistent with a benign cartilaginous tumor, an enchondroma. With the history of pain, close clinical and MRI follow-up is recommended.

Ddx: Enchondroma Low-grade chondrosarcoma, although the radiographic findings suggest a more benign lesion

Exam: No physical findings and no labs.

No MeSH data available.


Coronal STIR image of the proximal tibia  shows that the lobulated diaphyseal medullary mass becomes high signal intensity with focal areas of low signal intensity corresponding the stippled calcifications on the plain radiographs These findings are consistent with a benign cartilaginous tumor, an enchondroma. The patient’s bilateral lower extremity pain, was clinically thought to be secondary to the stress fractures (which were not seen on the MRI).  With the history of pain, close clinical and MRI follow-up is recommended.
