Summary:

Description
  • Radiopaedia case ID: 74204
  • Image ID: 52027097
  • Image stack position: 27/56
  • Plane projection: Axial
  • Aux modality: SWI
  • Study findings: There are multiple randomly distributed intra-axial subtle ring-enhancing lesions of varying size, predominately supratentorial and centered at the grey-white matter interface. The largest of these lesions, seen at the superior aspect of the lentiform nucleus measures up to 13 mm. The lesions demonstrate peripheral T2 hyperintensity suggesting perilesional edema with a thin high T1, low T2 rim, showing susceptibility effect suggesting hemorrhage (acute). All lesions diffusion restrict. Some of the lesions are associated with the precentral gyri (motor strips) and likely account for the clinical neurology. There is further disease within the brain stem involving the right midbrain with a deposit measuring up to 7 mm, demonstrating confluent susceptibility artefact. Overall, there are multiple acute hemorrhagic cerebral abscesses, predominantly within the supratentorial brain, some of which involve the motor strips bilaterally. Although ring-enhancing lesions carry a broad list of differentials, the constellation of signal abnormalities suggests CNS aspergillosis.
