What is the Difference Between Mucormycosis and Aspergillosis?
🆚 Go to Comparative Table 🆚Mucormycosis and aspergillosis are both fungal infections that can cause significant complications, particularly in immunocompromised individuals. Distinguishing between the two can be challenging due to overlapping clinical and radiological presentations. However, there are some differences that can help differentiate between the two:
- Antifungal sensitivity: Mucormycosis is resistant to voriconazole, while aspergillosis is sensitive to it.
- Clinical presentation: Although there is a marked overlap in symptoms, mucormycosis tends to cause more severe clinical symptoms, such as hemoptysis and local pain syndrome.
- Hyphal morphology: In histopathologic examination, mucormycosis appears as broad (6–16 µm), nonseptated hyphae with branches at right angles, while aspergillosis is characterized by thin, regular, septated hyphae.
Imaging features that may favor mucormycosis over aspergillus lung infection in a neutropenic patient include the bird's nest sign (seen less commonly in aspergillosis), more than 10 pulmonary nodules, pleural effusion, concomitant sinusitis, and development of infection despite voriconazole prophylaxis.
It is essential to distinguish between mucormycosis and aspergillosis because their treatments differ, and early detection and appropriate therapy can improve patient outcomes.
Comparative Table: Mucormycosis vs Aspergillosis
Here is a table comparing the differences between mucormycosis and aspergillosis:
Factor | Mucormycosis | Aspergillosis |
---|---|---|
Causative fungi | Mucorales | Aspergillus |
Affected population | Predominantly immunocompromised individuals | Predominantly immunocompromised individuals |
Common symptoms | Fever, dry cough, progressive dyspnea, hemoptysis | Fever, dry cough, progressive dyspnea, hemoptysis |
Imaging findings | Bird's nest sign, >10 pulmonary nodules, pleural effusion, concomitant sinusitis | Halo sign, air-crescent sign |
Antifungal sensitivity | Resistant to voriconazole | Sensitive to voriconazole |
Treatment options | Antifungal agents (posaconazole, amphotericin B deoxycholate, amphotericin B lipid complex, caspofungin), surgical debridement | Antifungal agents (voriconazole, liposomal amphotericin B, caspofungin, flucytosine, itraconazole), surgical debridement |
Both mucormycosis and aspergillosis are fungal diseases that predominantly affect immunocompromised individuals and cause serious infections. Diagnosis of these conditions is typically made through X-ray, CT scan, and microscopy, and treatment options include antifungal agents and surgical debridement.
