fungal rhino sinusitis (frs) is an important infection of para nasal sinuses, which encompasses two main categories; invasive and noninvasive forms according to histopathological findings. aspergillus spp are the most common species isolated from noninvasive form, while mucorales are more frequently isolates from acute infections.four hundred fifty patients suspected to fungal rhino sinusitis w...

Fungus is one of the causes of chronic rhinosinusitis. If the fungus occupies the sinus but does not invade the sinonasal mucosa, this is called sinus fungus ball. Any association between anatomical variations and fungus ball remains unclear. Sinus fungus ball is defined as non-invasive chronic fungal rhinosinusitis occurring in immunocompetent patients, and the maxillary sinus is the most comm...

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 ...

BACKGROUND Sinus fungus ball, an accumulation of fungal dense concretions, is a common disease in practice, and might cause fatal complications or lead to death once converted into invasive type. Early preoperative diagnosis of this disease can lead to appropriate treatment for patients and prevent multiple surgical procedures. Up to now, the diagnostic criteria of sinus fungus ball have been d...

patients with pulmonary cavities are usually exposed to other pulmonary infections, especially of fungus origin, such as asnprgillosis and coccidiomycosis. they are manifested by the formation of fungus ball in these cavities, which is completely resistant to anti-fungal therapy. in these circumstance the best method of treatment is removing of the ball by surgery, in this paper a case of pulmo...

Introduction: Pulmonary fungus ball is a rare complication in pre-existing pulmonary cavitary lesions, due to some chronic pulmonary diseases including tuberculosis, lung abscess and sarcoidosis. Fungus ball is mostly caused by aspergillus. In many patients, fungus ball is asymptomatic, but in a significant number of them it can develop cough and hemoptysis, which may be massive and fatal. The ...

The objective of this study was to demonstrate the correlation between endodontic treatment on maxillary teeth and fungus ball with inductively coupled plasma mass spectrometry measurement of zinc and other metals (barium, lead and copper) in fungus ball samples. Samples of normal maxillary mucosa were used as comparison. Metal concentration was also measured in several endodontic materials. A ...

OBJECTIVES/HYPOTHESIS Fungus balls are a common disease of the paranasal sinuses, usually involving the maxillary sinus. To clarify the pathology, we analyzed patients treated for maxillary sinus fungus balls to see whether the latter correlated with dentogenic factors. STUDY DESIGN Retrospective case analysis. METHODS Cases of maxillary sinus fungus balls diagnosed between January 2000 and...

Background: Bone erosion is a common manifestation of sinus fungus ball (SFB) on CT imaging, however, the relationship between CT imaging and clinical features of SFB with bone erosion were not clear. Purpose: To evaluate the CT imaging and clinical features of sinus fungus ball with bone erosion and to explore the possible factors underlying its formation. Material and methods: The clinical da...
