“…Postoperative mucocele formation after endoscopic sinus surgery has been reported with average time lapse between 2 and 6 years. 26,39,[41][42][43] Nonetheless, prior reports of mucocele formation after vascularized PNSF repair have been reported at 46 days 31 and at 4 months. 32 Different ideologies exist for the pathogenesis of mucocele formation, because there are a variety of etiologies that lead to sinus obstruction.…”

“…20 However, this patient's absence of previous trauma or surgery made this diagnosis unlikely. On CT scanning, 90 per cent of frontal sinus fungus balls show partial to complete, heterogeneous, central opacification of the frontal sinus, with a zone of reduced opacity between the central area and the bony sinus wall.…”

Isolated fungus ball mimicking mucocele or frontal sinus tumour: a diagnostic pitfall

Objective: To demonstrate the clinical, radiological and diagnostic pitfalls of managing an isolated frontal sinus fungus ball, and to compare with the literature.Material and methods: Retrospective analysis of two cases and literature review. Results: Isolated frontal sinus fungus ball is a rare cause of frontal sinus disease. We present two cases of isolated frontal sinus fungus ball which pre-operatively were suspected to be either a tumour or a mucocele. In both cases, cheesy, clay-like material was found intra-operatively within the frontal sinus, suggesting a fungus ball. Effective treatment included surgical debridement via an exclusively endoscopic or an external approach, variously. Final histopathological and mycological analysis revealed Aspergillus fumigatus. A literature review revealed 20 reported cases of isolated frontal sinus fungus ball, confirming the low prevalence of the disease.Conclusions: Frontal sinus fungus ball should be considered in the differential diagnosis of chronic, nonspecific forehead symptoms. To evaluate the underlying disease, computed tomography scans should first be performed, followed by magnetic resonance imaging if malignancy is suspected. It is essential to be aware of the possibility of an atypical fungus ball appearance on computed tomography and magnetic resonance imaging scans. If bony destruction and calcification coexist on radiological images, then endoscopic biopsy is an indispensable part of the diagnostic procedure, and should be performed to collect material for both histological and mycological analysis, and to aid surgical planning. In cases of sinus fungus ball, an endoscopic approach for biopsy may be curative.

“…7,12 Because of the often slow-growing nature of frontal sinus mucoceles and the demographic data of trauma patients, very few patients have a welldocumented history of trauma to the frontal sinus. In a published data review and experience from their institution, Koudstaal et al 13 identified only 13 patients with a history of trauma to the frontal sinus preceding the development of a mucocele, a remarkably small number when one considers the incidence of frontal sinus fractures.…”

“…This can result in complications such as meningitis, meningoencephalitis, pneumocephalus, brain abscess, seizures, and cerebrospinal fluid (CSF) fistulas. 2,3,7 Very rarely, they will present as a forehead mass or swelling. To the best of our knowledge, only 5 cases of frontal sinus mucocele presenting as a forehead subcutaneous mass or swelling have been previously reported.…”
