Subdural empyema complicated with intracranial hemorrhage in a postradiotherapy nasopharyngeal carcinoma patient: A case report and review of literature

Figure 1 Radiographic images of the presenting case. A: Preoperative unenhanced CT revealed a hypodense crescent-shaped extra-axial fluid collection mixed with a local hyperdense lesion over the right hemisphere and marked midline shift of the brain; B: Immediate postoperative unenhanced CT scan demonstrated a slightly decreased subdural empyema and retraction of middle structures of the brain; C: An enhanced CT scan which is corresponding to figure B showed no enhancement of the thick rim or adjacent cerebral cortex; D: Hypointense areas (finger-like) were seen in the right lower temporal lobe; E: Unenhanced CT scan indicating significantly decreased subdural empyema at day 4; F: Unenhanced CT scan showed newly subdural hemorrhage and the middle shift of brain structures at day 5.
