Migration of Iophendylate Myelography Contrast to the Brain With Successful Thrombectomy | Neurology
A 77-year-old woman with hypertension and atrial fibrillation presented 1.5 hours after acute onset of aphasia and right hemibody weakness, NIHSS 16. NCCT showed no acute changes; CTA left M1 near-occlusion; CTP no core infarct, 26cc penumbra. These findings were partly obscured by multiple hyperdensities in subarachnoid space (Figure 1). The patient had a CT myelogram in the 1980s for back pain, presumably with iophendylate (brand name Myodil or Pantopaque), an oil-based contrast medium with very slow
