Summary
Spinal adhesive arachnoiditis (SAA) is a rare condition causing disability. A retained lumbar drain catheter was found causing adhesions in a patient misdiagnosed with a spinal tumor, highlighting diagnostic challenges.
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Spinal adhesive arachnoiditis (SAA) is a rare, debilitating condition affecting spinal meninges.
- It can mimic spinal tumors on imaging, complicating diagnosis and treatment.
Observation:
- A patient with worsening back pain and leg weakness was initially suspected of having a spinal tumor.
- Intraoperative findings revealed dense arachnoid adhesions, not a tumor, with a retained lumbar drain catheter embedded within.
Findings:
- The retained catheter likely contributed to the development of SAA.
- Magnetic Resonance Imaging (MRI), while sensitive, can misdiagnose SAA as an intradural tumor.
Implications:
- This case underscores the importance of meticulous surgical procedures and complete foreign body removal.
- Further research is needed for SAA prophylaxis and improved treatment strategies to enhance neurological recovery.
