Contrast-enhanced computed tomography (CT) scan of the brain confirmed the diagnosis of brain abscess by demonstrating a well-defined ring-enhancing hypodense lesion in the right parieto-occipital region, measuring 1.4 x 1.5 x 1.5 cm (CCxTVxAP dimensions) with surrounding cerebral edema (Fig. 1A and B).
Contrast CT brain two weeks after the antibiotics therapy demonstrates marked reduction in the size of the abscess and surrounding edema (red arrow) (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.).
