Ring enhancing cerebral abscess

Presentation

headache, drowsness and fever

Patient Data

Age: 40 years
Gender: Female
Modality: MRI

A Well defined left high parietal thick walled cystic lesion showing the following criteria: central high intensity in T2WI and FLAIR while low signal thin rim abscess capsule; restriction of diffusion of its central content with low ADC value while high signal capsule; peripheral enhancement in post contrast study; associated with perilesional vasogenic edema that facilitated in DWI

Right temproparietal white matter vasogenic edema exhibiting hypointense signal in T1Wi and hyperintense signal in T2WI with no definite enhancement and no restriction in DWI suggestive of multiple areas of cerebritis

Case Discussion

The diffusion has an important role in the diagnosis of cerebral abscess and to differentiate it from the other ring enhancing lesions as metastases and gliomas.

The abscess center showing diffusion restriction while its wall is facilitated in DWI.
