Background:
Intraparenchymal pericatheter cysts (IPCs) are a rare ventriculoperitoneal shunt (VPS) complication, with only a few cases recorded in the literature.
Case Description:
We report a 22-year-old woman admitted with headache, papilledema, vision loss, and a history of leukemia. Lumbar puncture revealed idiopathic intracranial hypertension (IIH). Three months after VPS implantation, she was readmitted with headache and worsening of visual impairment. CT evidenced a IPC with perilesional edema. Intraoperatively, a shunt revision and cyst drainage were opted for. We present a discussion and literature review on this unique complication of VPS, with emphasis on management.
Conclusion:
It is important to understand and consider IPCs as complications of VPS surgery, including in adult patients and IIH cases.
