Glioblastoma multiforme presenting with an open ring pattern of enhancement on MR imaging.

CONCLUSION: The unique open ring enhancement pattern of this lesion on initial imaging is highly specific for a demyelinating process, however, high-grade glial neoplasms can also present with complex and irregular ring enhancement including an open ring sign. Therefore, other imaging modalities should be used, and close follow-up is warranted when the open ring sign is encountered. PMID: 28680725 [PubMed - in process]
