Choroid Plexectomy for Hydrocephalus Management in a Pediatric Patient with a Pilocytic Astrocytoma.

Choroid plexectomy is a debated surgical intervention for the treatment of hydranencephaly and chronic infected hydrocephalus. We present a case of a 2-year-old with multiple shunt revisions and hydrocephalus secondary to a pilocytic astrocytoma. He presented with new somnolence, vomiting, and abdominal distension 5 months post subtotal tumor resection, with a history of shunt revisions and infections related to his chemotherapy-induced low white blood cell count. He underwent choroid plexus coagulation and resection. Three years post choroid plexectomy, the patient continues to meet neurodevelopmental milestones and is shunt independent. While ventricular shunt placement is the most common course of treatment, choroid plexectomy should be considered as an alternative treatment of hydrocephalus secondary to other neurological disorders, especially when the patient is immunocompromised, to avoid the recurrent infections seen with shunt placement.
