Background:
Monostotic fibrous dysplasia rarely involves the lumbar spine. Although its optimal surgical management is unknown, some recommend complete resection to decrease the likelihood of future recurrence.
Case description:
A 41-year-old female presented with fibrous dysplasia involving the right L4 lamina and spinous process. Following image-guided en bloc resection, the patient remained asymptomatic without evidence of recurrence 8 months later.
Conclusion:
Image-guided excision of monostotic fibrous dysplasia involving the right L4 lamina and spinous process was successfully performed without clinical or radiographic evidence of recurrence within 8 postoperative months.
