ABSTRACT

Diagnosis: Cerebral abscess

History: 52 y.o. man presents to the emergency room with headache and confusion. History of tooth extraction approximately three weeks ago.

Findings: Non-contrast CT scan demonstrates a well defined round mass with low density center and associated vasogenic edema. MRI demonstrates thin rim of enhancement with inherent low T2 signal intensity in rim. Restricted diffusion is present on DWI.

Ddx: Metastatic disease GBM (glioblastoma) Resolving contusion Tumefactive multiple sclerosis Cerebral abscess

Dxhow: Surgical drainage

No MeSH data available.


Post-gadolinium T1 weighted MRI demonstrates an "open ring" sign.  In addition, there is no surrounding peri-lesional vasogenic edema and the white-matter signal abnormality ends at edge of enhancement.  These are all features of inflammatory or "tumefactive" demyelination (TDL); and, they can be useful to differentiate TDL from abscess and neoplasms.
