Summary:

Description
  • Radiopaedia case ID: 84436
  • Image ID: 53935903
  • Image stack position: 57/86
  • Plane projection: Axial
  • Aux modality: FLAIR
  • Study description: MRI brain
  • Modality: MRI
  • System: Central Nervous System
  • Findings: Centered within left anterior inferior temporal lobe, collection of relatively homogeneous low T1 and high T2 signal with relatively thin, regular peripheral enhancement measuring 21 x 30 x 29 mm (TR x AP x CC) and corresponding central diffusion restriction in keeping with abscess. Hyperintense T2 signal of the surrounding white matter in keeping with edema.Subdural collection with corresponding diffusion restriction in keeping with subdural empyema, extending along the inferior aspect of the left temporal and medial aspect of left temporal, occipital and parietal lobes, measuring up to 8 mm depth on coronal reformats at the inferior temporo-occipital region.The ventricular system is clear with no evidence of hydrocephalus or pyocephalus.No other intra-axial space-occupying lesion.No significant midline shift or herniation.Enhancing soft tissue mass at the left skull base encasing the left internal carotid artery, soft tissue mass lesion within left external acoustic canal and fluid signal within the left mastoid air cells, overall similar to recent MRI neck.Enlarged left neck nodes similar to prior.Right maxillary sinus polyp also similar to prior.Opinion:Left temporal lobe abscess with associated left subdural empyema, presumably secondary to eroding left skull base mass, which is similar in size to prior.
