“…Although tissue invasion is atypical of fungal balls, several reports of more aggressive cases exist. 20,21 In these rare instances, fungal balls have been associated with local tissue invasion, behaving in a fashion more characteristic of chronic invasive fungal sinusitis. Some controversy exists regarding whether sinus mucosa should be examined for evidence of tissue invasion in cases of obvious fungal ball.…”

“…Cultures often fail to detect Mucor species, because fungi are very often degenerating and the mucus is viscous, inhibiting the proper contact of the species with the growth medium Katzenstein 1983). Molecular techniques, like DNA sequencing and hybridization, offer the opportunity to detect fungi in fungus balls (Robey et al, 2009). Kostamo et al (2004) highlight that the detection of fungi in chronic sinusitis cannot prove evidence of the fact that they are responsible for the pathology, but it supports the opinion that the switch in the microflora is related to the chronic course of the disease.…”

“…Aspergillus species are usually involved in fungus balls and are mostly related to immunosuppressed individuals (Robey et al, 2009). Mucor colonization of the sinuses is rare and usually occurs without predisposing factors in immunocompetent individuals in contrast to mucormycosis which is the second most frequent mycosis caused by moulds in immunocompromised patients (Sugar 1992).…”

Paranasal sinus fungus balls are a form of fungal infection, mostly associated with the maxillary sinus. They are noninvasive lesions that usually develop in immunocompetent individuals with no predisposing factors. Fungus balls are mostly related to Aspergillus species, whereas Mucor species have been rarely reported. Transformation of a fungus ball into an invasive mycosis may commence when the patient becomes immunosuppressed. It is of clinical importance to distinguish fungus balls from common sinusitis, neoplasia, hemorrhage, and other conditions. Histopathological investigation reveals the presence of nonseptate hyphae, whereas cultures often fail to detect Mucor species. Magnetic resonance imaging (MRI) is more sensitive than computed tomography (CT) scan in diagnosing fungal sinusitis, but there is no clear superiority of one imaging modality over the other. CT remains the method of choice. We present a case of a Mucor fungus ball of the maxillary sinus that transformed into an erosive noninvasive Mucor mycosis in patient with concomitant oral cancer. Diagnostic reasoning and difficulties in radiological diagnosis are being discussed.

“…Sclerosis of the sinus wall was the most common CT finding in previous studies. [8][9][10] When there is a suspicion of a fungal disease with or without an intra-cranial or intra-orbital invasion and the CT images are not conclusive for identification of fungal disease, MRI should be used for differential diagnosis.…”

Fungal rhino-sinusitis (FRS) can be broadly divided into two categories based on histopathological findings: invasive and non-invasive, depending on the status of the mucosal layer. The invasive diseases include (1) acute invasive (fulminant) FRS, (2) granulomatous invasive FRS and (3) chronic invasive FRS. The non-invasive diseases include (1) saprophytic fungal infestation, (2) fungal ball, and (3) fungus related eosinophilic FRS that includes allergic fungal rhinosinusitis. Invasive FRS mostly affects immuno-compromised patients, whereas the non-invasive form occurs in immunocompetent patients.[1]Fungal ball is described as the presence of non-invasive accumulation of dense conglomeration of fungal hyphae in one sinus cavity. Various terms, such as mycetoma, aspergilloma, and chronic non-invasive granuloma have been used in the literature.

AbstractObjective: The aim of the present study was to analyse the clinical, radiographic, and surgical outcomes of paranasal fungus ball. Methods:A retrospective data analysis was performed on 16 patients who underwent endoscopic sinus surgery for paranasal sinus fungus ball between December 2005 and November 2014. The patient's demographic data, clinical presentations, radiological findings and surgical outcomes were analysed.Results: There were 10 female (62.5%) and six male (37.5%) patients with a mean age of 53.6 (range: 32 to 74) years. Most common symptoms were headache and facial pain. Computed tomography showed a hyper-dense area in 12 patients (75%) and sclerosis in bony walls of the sinus in 13 patients (81.3%). Magnetic resonance imaging revealed a marked low intensity on T2 weighted images in all cases (100%). All patients were treated with functional endoscopic sinus surgery. Only one patient had a recurrence in the postoperative period. Conclusion:The surgical opening of affected sinus ostium and removal of the fungal concentration were the treatment of choice in all cases.
