Pre-operative embolization of a choroid plexus carcinoma: review of the vascular anatomy
Aim The purpose of this case is to highlight the benefits of preoperative embolization as well
as to review the vascular anatomy that needs to be recognized in order to perform pre-
operative embolization of choroid plexus tumors. Method We achieve this by presenting the
case of a 12-month-old female who had symptoms of raised intracranial pressure. MRI
demonstrated a large vividly enhancing mass centered within the atria of the right lateral
ventricle associated with hydrocephalus in keeping with a choroid plexus tumor. Result …

Aim
The purpose of this case is to highlight the benefits of preoperative embolization as well as to review the vascular anatomy that needs to be recognized in order to perform pre-operative embolization of choroid plexus tumors.
Method
We achieve this by presenting the case of a 12-month-old female who had symptoms of raised intracranial pressure. MRI demonstrated a large vividly enhancing mass centered within the atria of the right lateral ventricle associated with hydrocephalus in keeping with a choroid plexus tumor.
Result
Enlarged anterior and posterior choroidal arteries supplying the tumor were noted on the MRI scan. Pre-operative embolization was performed with NBCA glue via the anterior and posterior choroidal arteries. Subsequently, total surgical resection was achieved with only 200 cc of blood loss. Pathology confirmed a choroid plexus carcinoma.
Conclusion
Pre-operative embolization can be useful in minimizing blood loss during excision of choroid plexus tumors. It is important to understand the anatomy of the anterior and posterior choroidal arteries to perform embolization of these tumors safely.
