Case 105 Diagnosis

Aspergillus

Differential Diagnosis

  • Candida albicans: infections frequently involve the posterior pole but are typically smaller and less likely to be hemorrhagic; more likely to have broad areas of ischemic infarction
  • Pseudallescheria boydii: rare endogenous infection which occurs in similar settings as endogenous Aspergillus; indistinguishable histopathologically
  • Cryptococcus: multifocal chorioretinitis in conjunction with meningitis
  • Coccidioides: multifocal choroiditis with numerous scattered, discrete lesions less than one disc diameter in size
  • Endophthalmitis associated with bacterial or other fungal organisms
  • Intraocular lymphoma: typically associated with more vitritis
  • Toxoplasmosis: unilateral white-yellow retinal lesions associated with vitreous cells. An adjacent chorioretinal scar may be present
  • Acute retinal necrosis: multiple white areas of opaque necrotic retina located more peripherally which coalesce
  • Cytomegalovirus retinitis: perivascular areas of necrotic retina in immune compromised patients
