MRI Brain abnormal “Aspergillosis”

  • —Aspergillus fumigatus infection is seen predominantly in immunocompromised patients
  • —hematogenous spread of pulmonary disease and less commonly caused by direct extension of disease in the nasal cavity and paranasal sinuses
  • —produces meningitis and meningo-encephalitis.
  • —CT scans low-density areas with little or no contrast enhancement and mass effect, representing areas of infarction
  • — Incomplete ringlike contrast enhancement may be seen
  • —MRI studies demonstrate a peripheral ring of low signal intensity
  • —The ring of low signal intensity corresponds to a dense population of Aspergillus hyphal elements and small areas of hemorrhage histologically.
