Conus Medullaris Syndrome following Radionuclide Cisternography

الملخص EN

Radionuclide cisternography is generally considered to be a safe procedure without significant neurological complications.

However, in this report we present a patient who developed conus medullaris syndrome following radionuclide cisternography.

A 46-year-old woman underwent lumbar puncture followed by radionuclide cisternography with the diagnosis of hydrocephalus.

After the cisternography, she developed voiding difficulty with perineal sensory loss.

Lumbar MRI revealed a high signal intensity lesion on T2-weighted images at the level of conus medullaris.

Considering its clinical course and MRI findings, a spinal cord infarction is highly suggested as a cause of the conus medullaris lesion in this patient.
