Non-enhanced brain magnetic resonance imaging. Left inset: imaging suggested an intraventricular empyema (pyogenic ventriculitis) in the occipital horn of the left lateral ventricle, visible only in the diffusion-weighted image (arrow). Right inset: the collection is invisible in the T2-weighted image. There is a notable ventricular enlargement.

The repeated cranial MRI showed hydrocephaly and IVT empyema in the occipital horn of the left lateral ventricle [Figure 1].
Non-enhanced brain magnetic resonance imaging: follow-up 3 weeks after the intrathecal antibiotic therapy. The collection is no longer visible both in the diffusion-weighted image (left inset) as well as the in the T1-weighted image in (right inset). The hydrocephaly although still present, is slightly improved.

A control MRI [Figure 2] demonstrated as well the resolution of the ventricular empyema.
