Craniofacial invasive aspergillosis in an immunocompetent patient: a case report

Invasive aspergillosis of the skull base in an immunocompetent patient: a diagnostic challenge

We describe the case of a 32-year-old man from Cape Verde having headache and increasing visual loss. Clinical and radiological investigations disclosed a massive destructive lesion involving the anterior and central skull base, orbit and nasoethmoid region initially interpreted as a malignant small round cell tumour. Surgical biopsies were negative for neoplasm, showing an intense inflammatory infiltrate together with fungus, later characterised as Aspergillus flavus spp. The patient was immunocompetent with no evidence of congenital or acquired immunodeficiencies. Invasive fungal infections in immunocompetent patients are rare and can be a diagnostic challenge. The best diagnostic clues include the patient's origin from tropical climates, imaging features and the identification of fungal hyphae on pathology specimens. Although a devastating disease in immunocompromised patients, craniocerebral aspergillosis in immunocompetent patients carries a better prognosis. Available literature supports the combined used of 'conservative' surgical resection and antifungal therapy as the best treatment option.

Invasive fungal infection by Aspergillus flavus in immunocompetent hosts: A case series and literature review

Invasive aspergillosis usually affects immunocompromised hosts with variable manifestations depending on the site of infection. In this article, we present two cases of invasive Aspergillosis in two non-immunocompromised patients; both cases had a paranasal sinuses infection, with intraorbital and intracranial extension, requiring surgery and antifungal treatment with Voriconazole. These cases were initially diagnosed as paranasal sinus neoplasms. However, the pathology and microbiology studies revealed invasive fungal infection by Aspergillus flavus.

Outcomes of Three Patients With Intracranially Invasive Sino-orbital Aspergillosis

PURPOSE

Although rare, invasive aspergillosis with intracranial spread usually is fatal and necessitates prompt diagnosis and treatment. We describe the prognoses for survival and vision in 3 consecutive patients with vision-threatening invasive sino-orbital aspergillosis.

METHODS

A case series of 3 patients, with review of treatments and outcomes.

RESULTS

Three diabetic patients presented with significant eye pain and headache, followed by progressive ophthalmic symptoms including vision loss and limitation of ocular motility. Histologic examination showed numerous hyphae of Aspergillus fumigatus. Following early diagnosis and surgical debridement, 1 patient (case 1) showed vision improvement, from counting fingers to 20/20. The other 2 patients, who were initially treated with corticosteroids after presumptive diagnoses of nonspecific orbital inflammation, showed no recovery of vision from no light perception, and 1 (case 3) died of massive intracranial spread and side effects of antifungal agents caused by delayed diagnosis and long-term use of corticosteroids.

CONCLUSIONS

Invasive sino-orbital aspergillosis with intracranial invasion often may resemble inflammatory conditions. Early diagnosis and surgical intervention are required to improve vision and survival. Repeated biopsies often are necessary to rule out fungal sinus infection before considering steroid use, especially in diabetic patients.
