Summary:

Description
  • Radiopaedia case ID: 60342
  • Image ID: 38959471
  • Image stack position: 25/72
  • Plane projection: Axial
  • Aux modality: DWI
  • Study findings: Peripherally enhancing, ovoid lesion in the right frontal lobe with abundant surrounding vasogenic edema demonstrates linear almost continuous smooth low T2/susceptibility weighted artefact peripherally along the area of enhancement. There is true diffusion restriction centrally within the lesion with the lowest ADC value of approximately 530 x 10-6 mm2/s. The lesion extends up to the anterior horn of the right lateral ventricle, although there is no abnormal enhancement of the ependyma to suggest ventriculitis. Severe surrounding vasogenic edema causing sulcal effacement at the right frontal lobe, effacement of the anterior horn of the lateral ventricles, and 6 mm of midline shift to the left. Edema spreads through the anterior part of the corpus callosum without mass-like expansion. No other lesions identified. Conclusion: Features are those of a cerebral abscess.
  • Modality: MRI
  • System: Central Nervous System
  • Findings: Peripherally enhancing lesion in the right frontal lobe is surrounded by abundant vasogenic edema.
