Rhinosinusal mucormycosis is a life-threatening disease caused by fungus of the order Mucorales, which commonly affects individuals with diabetes and those in immunocompromised states. It is the most common form of mucormycosis with a high mortality rate (50-80%). Treatment options include reversal of the underlying risk factors when it is possible, systemic antifungal medication and radical surgical debridement. Prognosis is reserved because of the high potential of invasiveness, so diagnosis and early treatment are essential. Herein, we make a review about the most important features of this pathology and we report two cases of rhinosinusal mucormycosis with similar presentations who followed the same treatment protocol – extended surgical debridement of the necrotic tissue combined with systemic antifungal treatment (Amphotericin B). Complete recovery was achieved in one patient, whereas in the other one, due to late presentation, massive extension and incomplete surgical debridement, the disease was complicated with multiple organ dysfunction and cerebral stroke. By presenting these cases, we would like to point out the importance of early diagnosis, appropriate medical and surgical therapy to obtain a significant survival rate in patients with this fatal disease.

We report a case of a 47-year-old patient recently diagnosed with left abducens nerve palsy, who was admitted in our clinic with diplopia. The cranio-facial CT scan revealed left sphenoid fungal rhinosinusitis and the patient underwent endoscopic surgery with complete removal of the fungal material. The immediate postoperative evolution of the patient was favourable, with partial improvement of diplopia. The first month follow-up visit revealed the recurrence of the diplopia, so the patient performed an MRI scan of the brain that showed a cavernous sinus meningioma. The patient was referred to a neurosurgeon who choose a "wait-and-see" strategy instead of surgery. The paper presents the limits of computed tomography versus magnetic resonance imaging in the radiologic diagnosis of intracranial tumors.
