A CT scan was performed [Figure 1] revealing a left parietal lesion, which was initially presumed as a tumor.

Axial brain MRI images demonstrate a rim-enhancing (a), collection of fluid which does not attenuate on FLAIR (b), with true diffusion restriction (c and d), indicative of a brain abscess. Postoperative image (e) was acquired 2 months after evacuation and demonstrates no signs of fluid collection or gadolinium enhancement.

BA [Figure 2a-d]. Blood cultures were obtained and a CT scan of the thorax, abdomen and pelvis as well as a transesophageal echocardiogram were performed, to rule out a possible primary location. The postoperative brain MRI demonstrated only the usual postoperative changes of the brain without any sign of fluid collection or gadolinium enhancement [Figure 2e].
