Summary
A giant pseudomeningocele after spinal surgery was successfully located using radionuclide SPECT/CT cisternography. Surgical repair of the dural defect resolved the condition, with no recurrence observed on follow-up MRI.
Area of Science:
- Neurosurgery
- Radiology
- Medical Imaging
Background:
- Post-surgical complications can include pseudomeningoceles, which are fluid collections.
- Giant pseudomeningoceles pose diagnostic and management challenges.
Observation:
- A 32-year-old male presented with a giant pseudomeningocele 6 months post-spinal surgery.
- Magnetic Resonance Imaging (MRI) revealed the large pseudomeningocele.
Findings:
- Radionuclide SPECT/CT cisternography pinpointed the cerebrospinal fluid (CSF) leak at the L4 vertebral level.
- Surgical correction of the dural defect was performed.
Implications:
- This case highlights the utility of radionuclide SPECT/CT cisternography in localizing post-surgical CSF leaks.
- Successful surgical intervention led to the resolution of the giant pseudomeningocele and prevented recurrence.
