Microbiology

  • Mucorales (50%)
  • Aspergillus (50%)
  • Fusarium (rare)

Clinical Presentation

  • Difficult to distinguish from bacteria
  • Risk factors: DM, solid organ transplant, hematologic transplant
  • Edema and paresthesias are common
  • NP scope normal in ~30%; black eschar in 50%

Management

  • CT for extrasinus invasion
    • MRI is more sensitive
  • Debridement
  • Lipsomal amphotericin B 5 mg/kg
    • Every day of delay increases mortality
    • 3 week induction, then switch to posaconazole or isuvaconazole for 3-6 months
  • Decrease immunosuppression
