Biopsy revealed polypes and mucocele like cystic tissues. The patient, followed-up and treated with rhinocerebral mucormicosis, was transferred to intensive care unit after deterioration of his general condition.After approximately 45 days of follow-up and treatment, the patient was lost due to multiple organ failure.Conclusion: Rhinocerebral mucormycosis is an emergency that requires a multidisciplinary approach. Presence of one or more of the non-traumatic orbital apex syndrome findings should alert emergency physicians. In this and similar infections with high mortality rates, early diagnosis and treatment may lead to good results.eninfo:eu-repo/semantics/openAccessEmergency departmentFungal infectionRhinocerebral mucormycosisScience & technologyLife sciences & biomedicineEmergency medicineArticle10610712410.33706/jemcr.932160
