Not all anosmia and fever was COVID-19 infection: a case report

COVID-19 pandemic touch all part of world to the date more than fifteen millions of patients are infected by virus including about 1,388,926 deaths (European Centre for Disease Prevention and Control an agency of the European Union). Morocco has put in place strict containment measures to control the disease and prevent the saturation of health systems. One of the great difficulties is to quickly identify asymptomatic and paucisymptomatic cases which function as an important vector of contagion. Anosmia and fever are one of revealed mode for the young patient but is not all the case. We report one case in the sense. A 40-year-old man without medical history was admitted in the hospital after complaining 3 days ago clinical symptoms of fever, cough, headache and anosmia. Immediately, the patient benefits of COVID-19 protocol, measure of fever, nasal swab and polymerase chain reaction (PCR) test. Despite the negativity of PCR test of COVID-19, the patient was placed in isolation. Two days later, he presented a generalized seizures, then we performed a cerebral computed tomography scan (CT scan) which showed a bilateral frontal oedema. The cerebral magnetic resonance imaging (MRI) revealed the presence of 4x4x4 cm well enhanced meningeal extra axial mass of the anterior skull base with peri-tumoral oedema corresponding to an olfactory groove meningioma. The tumour was totally resected through a left fronto-lateral approach. The postoperative courses were uneventful with the persistence of totally anosmia.
