Post non-ionic contrast myelogram

Case contributed by Chris O'Donnell
Diagnosis certain

Presentation

Sudden onset of seizures ~ 4 hours post lumbar myelogram.

Patient Data

Age: 65 years
Gender: Male

Hyperdense material consistent with radiographic (iodine-based) contrast in the CSF without apparent cerberal parenchymal abnormality although it is difficult to be certain given the overwhelming density of the CSF

Case Discussion

Complications following non-ionic myelography are now rare but include seizures, encephalopathy and diffuse cerebral edema. The presence of contrast in the cerebral CSF post myelography is not infrequent especially following a cervical myelogram.
