Early diagnosis of disc-space infection using Gallium-67
Insights
A pediatric disc-space infection was diagnosed in a young boy presenting with lumbar pain. Early antibiotic treatment and advanced imaging confirmed the infection, leading to successful management.
Area of Science:
- Pediatric infectious diseases
- Diagnostic imaging in pediatric orthopedics
Background:
- Disc-space infection is a rare but serious condition in children.
- Early diagnosis and treatment are crucial to prevent long-term complications.
Observation:
- A 4-year-old boy presented with progressive central lumbar pain and hamstring spasm.
- Initial lumbar-spine X-ray was normal, with minimal L-5, S1 spondylolysis.
- A gallium-67 scan showed abnormal uptake in the low lumbar spine region.
Findings:
- Eight weeks of antibiotic therapy preceded definitive diagnosis.
- Roentgenographic studies confirmed disc-space infection by showing L4-5 intervertebral disc space narrowing.
- A concurrent technetium-99m diphosphonate bone scan was normal.
Implications:
- Gallium-67 scintigraphy can be a valuable tool in diagnosing pediatric disc-space infections when initial imaging is inconclusive.
- Prompt antibiotic treatment is essential for favorable outcomes in pediatric disc-space infections.
- This case highlights the importance of considering advanced imaging in pediatric patients with persistent spinal pain.
Abstract:
A 4-year-old boy had had progressive central lumbar pain and hamstring spasm. He had a normal lumbar-spine x-ray except for minimal L-5, S1 spondylolysis, but gave an abnormal gallium-67 scan in the region of the low lumbar spine. Eight weeks following intensive antibiotic therapy, confirmation of the diagnosis of disc-space infection was established by roentgenographic studies that demonstrated narrowing of the L 4-5 intervertebral disc space. A technetium-99m diphosphonate bone scan, performed concurrently with the gallium-67 study, was normal.
