Black turbinate sign – an important MRI sign of mucormycosis; a deadly form of acute invasive fungal sinusitis seen in diabetic and immunocompromised patients. Fungal spores germinate to produce angioinvasive hyphae that cause infarction as they invade the nasal mucosa. This results in a ‘black’ area of non-enhancing mucosa which stands out against the normal enhancing mucosa. The sign may be critical to early detection and treatment of mucormycosis which when untreated can result in blindness and death within 2 weeks.
