Prevertebral fat in Madelung disease mimicking cervical spine injury: A case report.

Madelung disease is defined by multiple symmetric fatty accumulations, usually involving the upper trunk, and may sometimes have excessive fat deposition in the prevertebral space. On magnetic resonance imaging (MRI), findings of fat that are hyperintense on T1w and T2w images, may simulate subacute hematoma and mimic cervical spine injury. This is the first reported case of Madelung disease with prevertebral fat deposition mimicking prevertebral hematoma found in cervical spine injury on MRI. Fat suppression techniques are helpful in order to differentiate between these two conditions, which should be taken into consideration during routine clinical practice.
