Patient Data

Age: 2 years
Gender: Male

A large expansile mass lesion with fluid-fluid level involving the body and posterior arch elements of L3 vertebra. The lesion causes spinal canal stenosis and compresses the thecal sac to the left side. The lesion shows peripheral enhancement on post contrast images.

Rest of the vertebral bodies and posterior arch elements are normal.

The intervertebral discs show normal height and signal characteristics. No evidence of disc bulge/herniation at any level.

The articulating vertebral endplates present continuous smooth contour.

Case Discussion

The fluid-fluid level on MR images is typically seen in aneurysmal bone cyst. About 20-30% of aneurysmal bone cysts can occur in the spine and sacrum.
