[Intraventricular contrast medium (non-ionic water soluble dimer) residue a month after injection; a case report]

Abstract:
We report a case with non-ionic water soluble dimer contrast media residue in the lateral ventricle a month after administration into the lateral ventricle. We believe that, in this subarachnoid hemorrhage patient, the intraventricularly instilled contrast media mixed with preexisting blood, aggregated and adhered to the ventricular wall.
Insights
A case study found non-ionic contrast media residue in the lateral ventricle one month post-administration. This residue likely formed from contrast media mixing with blood in subarachnoid hemorrhage patients, adhering to the ventricular wall.
Area of Science:
- Neuroradiology
- Neuroscience
- Medical Imaging
Background:
- Intraventricular contrast media administration is used in specific neurological conditions.
- Understanding the long-term behavior of contrast agents within the cerebrospinal fluid space is crucial.
Observation:
- A patient with subarachnoid hemorrhage received intraventricular contrast media.
- Follow-up imaging revealed residue within the lateral ventricle one month after administration.
Findings:
- Non-ionic water-soluble dimer contrast media formed aggregates.
- These aggregates adhered to the ventricular wall, suggesting interaction with blood products.
Implications:
- This finding highlights a potential complication of intraventricular contrast media use.
- Further research is needed to understand the long-term consequences and management of such residues.
