Sclerosing osteomyelitis of Garre

Case contributed by Dr Daniel M Carr


10 year old boy with intermittent left mandibular pain and swelling.

Patient Data

Age: 10
Gender: Male

3T MRI T1 and T2 axial and coronal sequences

Abnormal expansile appeance of the left manidble with abnormal and asymetric decreased T1 signal and increased T2 signal. There is thinning of the cortex as well as soft tissue edema adjacent to the lesion.


Bone window CT in axial and coronal planes

Bony expansion, cortical thinning, and diffuse sclerosis of the left mandible. This is present through mandibular ramus into the proximal mandibular body. There is marked periosteal reaction as well as cortical breakthrough surrounding the lesion. Edema (less obvious on bone windows) is present within the masseter muscle with adjacent mild fat stranding.

Case Discussion

Sclerosing osteomyelitis of Garre is a rare disease entity predominently affecting young adults and children. It frequently asymmetrically involves the mandible. It is thought to be associated with low grade infection and could be related to dental disease such as cavities. This version of chronic osteomyelitis is also known as periostitis ossificans. Treatments include observation, management of pain by NSAIDS, or bone curettage if conservative treatment fails.
