Clinical History

This is a 43-year-old male with a healing sacral fracture at S2. This examination is performed to evaluate the sacral fracture site and lumbosacral facets. There are no prior studies for comparison.

Technique

The patient was administered an IV injection of 25.4 millicuries of 99m Tc MDP, and three hour delayed SPECT images of the lumbar spine and sacrum were obtained.

Findings

The SPECT images demonstrate a focal area of increased uptake identified at approximately S2 of the sacrum compatible with a bony reparative process likely secondary to healing of known sacral fracture. There is also a focal area of increased uptake of the radiolabled phosphate seen of the pedicle of L5 on the left which also likely indicates an area of reparative bony productions. No other areas of increased uptake are identified. Normal activitiy is identified in the kidneys with excretion of the radiotracer seen in the bladder. The visualized facet joints do not show areas of abnormal focal uptake of the radiotracer.

Impressions

1. Area of focal abnormal uptake identified in the region of approximately S2 compatible with healing sacral fracture.

2. Focal area of increased uptake identified of the left pedicle of L5 compatible with healing fracture.

3. The facet joints in the lumbosacral region are intact without areas of abnormal focal uptake.
