Diagnostic Considerations

When evaluating a patient with suspected rhinocerebral mucormycosis, also consider the following:

  • Bacterial orbital cellulitis
  • Cavernous sinus thrombosis
  • Rapidly growing orbital tumor
  • Aspergillosis
  • Pseudallescheria boydii (asexual form:  Scedosporium apiospermum) infection (pseudallescheriasis)
  • Fusarium infection (fusariosis)

Aspergillosis, pseudallescheriasis, fusariosis, nocardiosis, Wegener granulomatosis, pulmonary embolism, and malignancy are also considered when evaluating a patient with suspected pulmonary mucormycosis.

Cutaneous disease considerations include ecthyma gangrenosum associated with pseudomonal infection and anthrax. Gastrointestinal disease considerations include bowel obstruction and ileocecal tuberculosis.
