MRI Brain Diffusion weighted images (Fig. 1a and b) demonstrating foci of bright signal (red arrows) involving non-dependent as well as the dependent portions of both lateral ventricles which shows dark signal (yellow arrow) on ADC (apparent diffusion coefficient) mapping (Fig. 1c) reflecting ventriculitis.

Suspecting complicated meningitis after MRI of brain (Fig. 1a-c) was obtained which revealed foci of bright signal involving both nondependent portions of both lateral ventricles as well as dependent portions of both lateral ventricles reflecting a diagnosis of intraventricular empyema.
Corresponding T2 weighted axial brain image showing no signal abnormalities.

No signal abnormalities were visualized on T2 weighted axial brain imaging (Fig. 2).
(a) and (b): MRI Brain (Diffusion weighted images) showing post therapy non-visualization of foci of bright signal in non- dependent as well as dependent portions of both lateral ventricles suggesting good response to therapy.
