Background:
Virchow-Robin spaces (VRS) or perivascular spaces are interstitial cystic spaces surrounding the vasculature of brain parenchyma and course from the subarachnoid space. Small VRS (<2 mm) appear in all age groups, but can enlarge and be confused with other lesions like cystic neoplasms. These enlarged VRS are termed giant tumefactive perivascular spaces (GRPVS).
Case Description:
We present the case of a 50-year-old male who presents with right eye pain, blurred vision, headache, and gait imbalance. He was diagnosed with GRPVS and underwent an endoscopic third ventriculostomy and cyst fenestration. Postoperative imaging showed a decrease in size of the ventricular system with evidence of flow through the aqueduct and ventriculostomy. Brainstem VRS cysts decreased in size.
Conclusion:
Unlike the other small number of case reports, this patient is unique in his age of presentation and successful endoscopic method of treatment. The endoscopic approach provided great exposure and adequate access to the lesions. Clinically, symptoms improved, cyst size decreased, and need for permanent shunt placement was averted.
