Sinus and lung were the most involved organs, while cerebral infection by mucormycosis is more fetal. This infection needs proper debridement and antifungal therapy. We report a 12-year-old diabetic girl with manifestations of fever, headache, and weakness in the right upper and lower extremities without any involvement of sinuses and lung. The patient had approximately normal routine laboratory data, and its CSF was not diagnostic. Because of its features in brain CT and MRI that suggested a necrotic lesion in the left parietal lobe, she was undergone craniotomy and received broad-spectrum antibiotics along with anti-fungal and anti-tuberculosis drugs. Histopathological findings of the mass, which was excised in craniotomy, confirmed the diagnosis of mucormycosis. Unfortunately, the patient died because of this invasive infection. The fatality of fungal infections, especially cerebral types, warn us to be aware of them in immunocompromised patients and perform the proper treatment to reduce its mortality. https://crcp.tums.ac.ir/index.php/crcp/article/view/239 https://crcp.tums.ac.ir/index.php/crcp/article/download/239/311
