Abstract
Introduction

On January 30, 2020, the World Health Organization (WHO) declared an international emergency due to the pandemic caused by a new coronavirus. There are some oncological indications that have special priority and studies are still being carried out despite the current situation. In these studies we have found suspicious findings of COVID-19 pneumonia in asymptomatic patients. The objective of this work is to assess the incidence of these findings, describe their characteristics and the evolution of suspected patients.

Material and methods

Oncological PET studies carried out in asymptomatic patients between March 18 and April 8, 2020 have been reviewed. Patients who presented findings suggestive of corresponding to an pulmonary infectious process were selected. Clinical findings have been reviewed to confirm or rule out SARS-CoV2 infection.

Results

During the specified period, a total of 129 PET-CT studies were performed. Of these, 11 (8.5%) found suspicious findings of a pulmonary infectious process. These were 8 men and 3 women aged between 30 and 79 years (mean 62.2).

Conclusions

Patients with COVID 19 can present few symptoms of the disease, and in PET-CT studies both presymptomatic and almost asymptomatic patients can be detected, so nuclear medicine physicians should take special attention to the pulmonary evaluation of PET-CT studies.

Resumen
Introducción

El 30 de enero de 2020 la organización mundial de la salud (OMS) declaró una emergencia internacional por la pandemia causada por un nuevo coronavirus. Existen algunas indicaciones oncológicas que tienen especial prioridad y se siguen realizando estudios a pesar de la situación actual. En estos estudios hemos encontrado hallazgos sospechosos de neumonía COVID-19 en pacientes asintomáticos. El objetivo de este trabajo es valorar la incidencia de estos hallazgos, describir sus características y valorar la evolución de los pacientes sospechosos.

Material y métodos

Se han revisado los estudios PET oncológicos realizados entre el 18 de marzo y el 8 de abril de 2020. Se han identificado los pacientes que presentaban hallazgos sugerentes de corresponder con un proceso infeccioso pulmonar de forma incidental en pacientes asintomáticos. Se han revisado las historias clínicas de estos pacientes para confirmar o descartar la infección por SARS-CoV2

Resultados

Durante el periodo especificado se realizaron un total de 129 estudios PET-TC con indicación oncológica. De ellos, en 11 (8,5%) se encontraron hallazgos sospechosos de proceso infeccioso pulmonar. Se trataba de 8 varones y 3 mujeres con edades comprendidas entre los 30 y los 79 años (media 62,2).

Conclusiones

Los pacientes con COVID 19 pueden presentar escasos síntomas de la enfermedad, y en los estudios PET-TC se pueden detectar tanto pacientes presintomáticos como pacientes casi asintomáticos por lo que los médicos nucleares deben prestar especial atención en la valoración pulmonar de los estudios PET-TC.
