Figure 1: (a) T1-weighted MRI axial view. High-signal intensity both in the eye and extrinsic orbital musculature on the left side. Poor definition of the optic nerve meningeal sheath (arrow) due to edema. (b) Fat suppression post-gadolinium T1-weighted MRI. Pachymeningeal (green arrowhead) and leptomeningeal enhancement (orange arrowhead). An ependymal enhancement is observed due to ventriculitis (arrow). (c) Contrast-enhanced CT scan. Hypodense fluid collection with rim enhancement involving the left gluteal muscles. (d) Lactose positive colonies of Klebsiella pneumoniae on MacConkey agar |
