From: Rare post-operative intracranial abscess due to Serratia marcescens: what we can learn from it?
A Immediate preoperative CT performed at initial encounter demonstrated a minimally mass effect in the left parietal region. B Large well-defined mass lesion in the left posterior region with adjacent skull erosion was shown in sagittal T1. On axial (C) and coronal (D) enhanced T1, strong post-contrast enhancement was observed with dural tail sign, exerting mass effect on the left lateral ventricle with resultant shift of midline structures to the right
