Aphasia and right hemiplegia after cervical myelography with metrizamide. A case report

We report a case of aphasia and right hemiplegia, developing after myelography with metrizamide and lasting for an unusually long time. The neurological disorders, manifested 1 h after the examination was completed, were due to accidental passage of contrast medium into the basal cisterns. In the light of analogous case reports in the literature, as well as experimental data concerning the biochemical activity of metrizamide, possible aetiopathogenetic mechanisms responsible for such disturbances are indicated. The authors underline the lack of effective therapeutic measures after the onset of the disorders, and thus the importance of preventing such complications that behave functionally as true ictuses although with no anatomic substratum.
