ABSTRACT

Aportamos dos casos de pacientes oncológicos en seguimiento rutinario con este tipo de artefacto, sin correlato morfológico en la TAC. Se procedió a la repetición del estudio en uno de ellos, lo que permitió comprobar una normalización de dicha hipercaptación, orientando a un posible artefacto. La PET-TAC con FDG se ha convertido en una herramienta imprescindible en el manejo del paciente oncológico. La distribución normal de la FDG y los posibles artefactos (pitfalls), incluidos aquéllos derivados de la corrección de atenuación basada en la TAC, han sido descritos en diversas revisiones. Sin embargo, sólo recientemente se ha publicado algún caso de falso positivo en forma de captación focal pulmonar de FDG(AU)


18F-FDG PET-CT has become an essential tool in oncology patient management. The normal distribution of the FDG and the possible artifacts (pitfalls), including those from CT-based attenuation correction, have already been described in several reviews. However, only a few cases of FDG focal lung uptake have been reported recently. We present two cases of oncology patients during a routine follow-up with this type of pitfall, without morphological correlation in the CT scan. We repeated the study in one of them, which made it possible to verify normalization of the hyperuptake, orienting us towards a possible pitfall(AU)
