Giant tumefactive perivascular spaces: A case report.

Conclusion: Often misdiagnosed as cystic neoplasms, giant tumefactive perivascular spaces are benign processes that can have a broad presentation with the most common finding being a headache. Key radiologic features, including smooth margins, isointensity to cerebrospinal fluid, and lack of postcontrast enhancement, are crucial to diagnosis, preventing unnecessary surgery with increased morbidity.
