Chronic Granulomatous Invasive Fungal Sinusitis in Patients With Immunocompetence: A Review

Persistent Severe Headache After Removal of Fungus Ball From the Sphenoid Sinus: A Case Report

OBJECTIVE

Granulomatous invasive fungal sinusitis (GIFS) is a rare and life-threatening disease, whereas fungus ball (FB) is the most common form of noninvasive fungal sinusitis. Both GIFS and FB primarily develop in immunocompetent patients, with the former associated with higher mortality and morbidity.

METHODS

A chart review and review of the literature.

RESULTS

We present the case of a 77-year-old woman with mixed fungal sinusitis who was successfully treated with voriconazole.

CONCLUSIONS

GIFS and FB can coexist in extremely rare cases, known as mixed fungal sinusitis; however, the diagnosis and subsequent treatment of mixed fungal sinusitis can be delayed because of a lack of awareness of the underlying concept. Therefore, it is crucial for clinicians to recognize the concept of mixed fungal sinusitis.

Invasive fungal sinusitis: A comparison of pediatric versus adult cases

BACKGROUND

Invasive fungal sinusitis (IFS) is a rare infection with high mortality, mainly impacting immunocompromised patients. Given its significant mortality, timely recognition and treatment is crucial. This study aims to highlight the differences in presentation of IFS between pediatric and adult patients to aid in prompt diagnosis and treatment of this condition.

METHODS

A comprehensive literature search of PubMed, EMBASE, Web of Science, Global Index Medicus, Global Health (EBSCO) and Cochrane Database of Systematic Reviews was conducted to identify articles relating to IFS. Patient demographics, comorbidities, presentation, disease characteristics, treatments and outcomes were extracted from the studies, and statistical analyses were conducted to compare these variables between pediatric and adult patients.

RESULTS

111 studies identified 22 pediatric and 132 adult patients worldwide. Children were more likely to have hematologic malignancies compared to adults (59.1 % vs. 15.2 %, p < 0.001). Facial symptoms such as pain, edema, and numbness were the most common symptoms for both age groups. In the pediatric population, fever and nasal or oral mucosal lesions were more common presenting symptoms (both p < 0.001). Pediatric patients were more likely to present without disease extension beyond the sinuses (p < 0.001). There was no significant difference in either medication treatment or mortality between the two cohorts.

CONCLUSION

IFS often presents with non-specific symptoms and a unique presentation in pediatric and adult populations. Clinical awareness of the varying presentations in both populations is important to treat in a timely manner given the rapid progression and high mortality rates of IFS.

Orbital Apex Syndrome Due to Aspergillus flavus Infection in Immunocompetent Patients: A Report of Two Cases

Aspergillus species are fungi that are commonly found in soil and decaying vegetation and have the potential to cause an orbital apex syndrome that is marked by ophthalmoplegia or vision loss. We report the clinical and investigational findings and outcomes of two patients with orbital apex syndrome. The first patient was a 26-year-old female, premorbidly healthy, who presented with a gradually increasing proptosis of the left eye with a reduction in vision. An MRI revealed findings consistent with proptosis, pansinusitis with a soft tissue opacity involving the left orbital apex with optic nerve compression, extending to the cavernous sinus with an associated temporal meningeal enhancement. Following functional endoscopic sinus surgery (FESS), Aspergillus flavus was grown in culture, and oral voriconazole was initiated. The second patient was a 53-year-old male who presented with bilateral reduction of vision and ptosis, proptosis with total ophthalmoplegia (third, fourth, and sixth nerve palsies) of the right eye. An MRI study revealed extensive involvement of the apex of the right orbit, the right cavernous sinus, the medial aspect of the left cavernous sinus, and the pituitary gland. A FESS was done, and the histopathology specimen was suggestive of aspergillosis, and the tissue fungal polymerase chain reaction (PCR) test was positive for Aspergillus flavus. He was treated with amphotericin B and oral voriconazole with significant improvement. Physicians need to have a high index of suspicion for invasive fungal sino-orbital infections, even in immunocompetent patients. The presence of nasal congestion, recurrent sinusitis, facial pain, headache, orbital cellulitis, proptosis, or ophthalmoplegia should prompt early investigations.
