Summary
This case study details a rare congenital lumbosacral limb duplication in a young boy. Surgical removal of the extra limb was successful, with further reconstruction planned.
Area of Science:
- Medical Case Study
- Congenital Malformations
- Skeletal Dysplasias
Background:
- Congenital limb duplication is a rare birth defect.
- Lumbosacral region duplication is exceptionally uncommon.
- Early diagnosis and intervention are crucial for patient outcomes.
Observation:
- A 4-year-old boy presented with a supernumerary lower limb attached at the lumbosacral region.
- The duplication included a pseudo-navel, pseudo-penis, and foot duplication.
- Associated anomalies included vertebral defects and hip dislocation.
Findings:
- Imaging revealed duplicated, inversely oriented pelvis, semi-vertebrae, scoliosis, and vertebral dysplasia.
- Magnetic resonance imaging showed a tethered spinal cord and sacral adipoma.
- Reduced motor conduction velocity was noted in the left peroneal nerve.
Implications:
- Successful surgical excision of the supernumerary limb was achieved.
- Further reconstructive surgery is planned for functional improvement.
- This case highlights the complexity of congenital lumbosacral anomalies.
