This condition was accidentally discovered with a panoramic radiography performed during a follow-up visit after a bilateral endodontic treatment. The patient did not report any specific sinonasal symptom such as purulent nasal discharge, loss of smell and cough, apart from an unspecific sinus pressure. The CT scans showed a bilateral inflammatory process into the maxillary-ethmoidal sinuses and an iron-like density within the maxillary sinuses, while nasal endoscopy showed purulent discharge in the ostiomeatal complex. The patient underwent functional endoscopic sinus surgery under general anaesthesia and the inflammatory material collected was histologically diagnosed as a rare case of bilateral fungus ball. The patient was dismissed the following day with no complications; there were not any sign of recurrence or symptoms during a 4\u2005month follow-up.<\/jats:p>","DOI":"10.1136\/bcr-2016-217930","type":"journal-article","created":{"date-parts":[[2016,12,15]],"date-time":"2016-12-15T09:13:51Z","timestamp":1481793231000},"page":"bcr2016217930","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Unusual case of bilateral maxillary fungus ball"],"prefix":"10.1136","volume":"2016","author":[{"given":"Alessandro","family":"Vinciguerra","sequence":"first","affiliation":[{"name":"Otolaryngology Department, ASST Santi Paolo e Carlo, Department of Health Sciences, Universit\u00e0 degli Studi di Milano, Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alberto Maria","family":"Saibene","sequence":"additional","affiliation":[{"name":"Otolaryngology Department, ASST Santi Paolo e Carlo, Department of Health Sciences, Universit\u00e0 degli Studi di Milano, Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paolo","family":"Lozza","sequence":"additional","affiliation":[{"name":"Otolaryngology Department, ASST Santi Paolo e Carlo, Department of Health Sciences, Universit\u00e0 degli Studi di Milano, Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alberto","family":"Maccari","sequence":"additional","affiliation":[{"name":"Otolaryngology Department, ASST Santi Paolo e Carlo, Department of Health Sciences, Universit\u00e0 degli Studi di Milano, Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2016,12,15]]},"reference":[{"key":"2025082707462480000_2016.dec15_1.bcr2016217930.1","doi-asserted-by":"crossref","unstructured":"Taschieri S , Torretta S , Corbella S , et al .
