Garré's chronic diffuse sclerosing osteomyelitis of the sacrum: a rare condition mimicking malignancy

Abstract

Garré's chronic diffuse sclerosing osteomyelitis (DSOM) is a rare disease that occurs most commonly in the mandible. We present a case of sacral DSOM that simulated an expanding destructive sacral tumour. Treatment was conducted on the basis of the available experience with the mandibular form of the disease, with partial symptomatic relief, but progressive sclerosis of the sacral lesion. To the best of our knowledge, this is the first case initially presenting in the sacrum. As an osteolytic expanding lesion simulating malignancy, it is important to recognize this entity in the sacrum.

Key words:

• Garré's chronic diffuse sclerosing osteomyelitis
• periostitis ossificans
• sacrum
