Case of the Week: Hyperparathyroidism with a Brown Tumor 2

This week I have a case with two interesting findings. The first is hyperparathyroidism which typically presents with a ground-glass appearance in the jaws instead of normal bone trabeculation.  This appearance is visible in all bones of the body and not just the jaws.  In some cases (~10%) there is absence of lamina dura surrounding the teeth.

There is also a well-defined, multilocular radiolucent entity in the right/anterior mandible that is consistent with a brown tumor. Brown tumors occur in patients who have had the disease for a long period of time.  They present radiographically similar to a central giant cell granuloma and histologically are the same as well.

Due to the two findings of this radiograph, I have two videos to share with you on hyperparathyroidism and central giant cell granuloma.

If you have any questions or comments, please leave them below. Thanks and enjoy!
