MR and CSF: First MR showed a hydrocephalic enlargement of the lateral ventricles (A FLAIR, B Gd-enhanced T1w, C T2w), while gadolinium-enhanced T1w did not show significant enhancement (B). Follow-up MR after secondary deterioration of the patient: showed leukemic infiltrations of the lateral ventricles walls (D FLAIR, E and F Gd enhanced T1w). CSF (G) revealed immature blasts with a pathological plasma-nucleus relation and basophilia of cytoplasm.
