ABSTRACT
Background: COVID-19 was first reported in Egypt on 14 February 2020 and continues to be a major threat to public health. Aims: We studied the incidence of incidental positron emission tomography/computed tomography (PET/CT) signs of COVID-19 in asymptomatic cancer patients and compared this with the number of reported COVID-19 cases during the same period. Methods: We included all cancer patients who underwent PET/CT at Misr Radiology Center, Cairo, between 2 May and 7 August 2020. Results: There were 479 patients who underwent PET/CT primarily for follow-up, and 66 (13.78%) of them showed radiological signs of COVID-19, with the peak incidence in weeks 7-8 of the study. This coincided and strongly correlated with the peak incidence of COVID-19 in Egypt (Pearson's correlation coefficient test = 0.943). Conclusion: The incidence of incidental PET/CT signs of COVID-19 was in accordance with the officially reported incidence of COVID-19 in Egypt between 2 May and 7 August 2020. These results could be helpful for implementing and adjusting public health and social measures during the COVID-19 pandemic.

Contexte : La COVID-19 a été signalée pour la première fois en Égypte le 14 février 2020 et demeure une menace majeure pour la santé publique. Objectifs : Nous avons étudié l'incidence des signes fortuits de COVID-19 détectés au moyen de la tomographie par émission de positons/de la tomodensitométrie (TEP/TDM) chez des patients asymptomatiques atteints de cancer. Puis, nous avons comparé cette incidence au nombre de cas de COVID-19 notifiés pendant la même période. Méthodes : Nous avons inclus tous les patients atteints de cancer qui ont subi une TEP/TDM au Misr Radiology Center, au Caire, entre le 2 mai et le 7 août 2020. Résultats : Au total, 479 patients ont subi une TEP/TDM principalement à des fins de suivi, et 66 (13,78 %) d'entre eux ont présenté des signes radiologiques de COVID-19, avec un pic d'incidence au cours des semaines sept et huit de l'étude. Cela a coïncidé et était fortement corrélé avec le pic d'incidence de la COVID-19 en Égypte (test du coefficient de corrélation de Pearson = 0,943). Conclusion : L'incidence des signes fortuits de COVID-19 détectés par TEP/TDM était conforme à l'incidence officiellement notifiée de la COVID-19 en Égypte entre le 2 mai et le 7 août 2020. Ces résultats pourraient être utiles pour mettre en œuvre et ajuster les mesures sociales et de santé publique durant la pandémie de COVID-19.Alternate :Background: COVID-19 was first reported in Egypt on 14 February 2020 and continues to be a major threat to public health.
