A case of a mobile choroid plexus cyst presenting with different types of obstructive hydrocephalus

Sho Tamai et al. Surg Neurol Int. .

Abstract

Background: Although it is well known that most choroid plexus cysts (CPCs) are asymptomatic, previous studies have reported that they can infrequently cause progressive hydrocephalus along with their increasing sizes. Among those cases, some patients needed cyst fenestration or cerebrospinal fluid (CSF) diversion to recover neurological deterioration. Meanwhile, some CPCs revealed spontaneous resolution, and in rare cases, they developed re-accumulation. Some reports have described series of radiological findings about their changes in location.

Case description: We present a 47-year-old male with CPC manifesting obstructive hydrocephalus. Radiological findings of the lateral and the third ventricles changed along with their different obstructive points, leading to their own symptoms. Because the patient's symptoms were not resolved completely, he underwent endoscopic fenestration for the cyst at the third ventricle. We could perform near-total resection, resulting in recovery of normal CSF flow. Postoperatively, the size of the ventricles decreased, with histological confirmation of a CPC. His symptoms resolved clearly without any complications.

Conclusions: It seems quite unusual that shift of the CPC location in the ventricle systems could induce not only different types of hydrocephalus but also their own symptoms. We need to consider that the location of CPCs might change when patients present with fluctuating symptoms over time.
