Focal fatty deposits in spinal bone marrow

Focal fatty deposits/replacement in spinal bone marrow are well-defined focal fat islands within the bone marrow of spine or other parts of axial skeleton.

Common in older individuals, related to age and not related to sex.

This process is a normal variant. Histologically, it is typical focal fatty replacement of hematopoietic bone marrow +/- presence of associated pathologic changes such as spondylitis, kyphoscoliosis, and spondylosis.

It is clearly demonstrated on MRI as small focal areas of high signals on T1WI and T2WI with suppressed signals on fat saturation sequences.
