ABSTRACT

Much can be learned by analyzing the pattern of contrast enhancement on MR or CT.

No MeSH data available.


Open-ring Pattern. Schematic Diagram. Instead of a complete circumferential rim, only part of the rim enhances. Also not that the lesion is not accompanied by surrounding vasogenic edema.  This appearance may be seen in multiple sclerosis (without mass effect as in this drawing), TDL tumefactive demyelination lesion (with mass effect), and also in fluid-secreting neoplasms (with associated mass effect and occasionally with surrounding vasogenic edema).  Fluid secreting neoplasms are usually low-grade (WHO 1 or 2) and include pilocytic astrocytoma, hemangioblastoma, ganglioglioma; or, intermediate, like pleomorphic xanthoastrocytoma (PXA).
