Hypoplastic lumbar pedicle in association with conjoined nerve root MRI demonstration
1Department of Radiology, Ege University Medical Faculty, Bornova, Izmir, Turkey.
Summary
This case study details rare lumbar vertebra anomalies, including a hypoplastic pedicle and conjoined nerve root. MR imaging effectively visualized these complex neural arch defects.
Area of Science:
- Radiology
- Orthopedic Surgery
- Developmental Biology
Background:
- Vertebral anomalies can lead to significant neurological and orthopedic complications.
- Accurate imaging is crucial for diagnosing and managing spinal malformations.
Purpose of the Study:
- To report a rare case of combined vertebral and neural arch anomalies in the lumbar spine.
- To illustrate the utility of MR imaging in delineating complex spinal malformations.
Main Methods:
- Case report detailing a patient with lumbar vertebral anomalies.
- Magnetic Resonance (MR) imaging was utilized to visualize the spinal structures.
Main Results:
- A case of aberrant hypoplastic pedicle of the fourth lumbar vertebra was identified.
- Associated anomalies included ipsilateral conjoined nerve root, retroisthmic laminar defect, dysplastic lamina and transverse process, enlarged neural foramen, and hypoplastic articular facets.
- MR imaging clearly demonstrated the extent and nature of these complex neural arch anomalies.
Conclusions:
- This case highlights a rare constellation of lumbar vertebral and neural arch anomalies.
- MR imaging is invaluable for the comprehensive evaluation of such complex congenital spinal defects.
