RESUMEN
Presentamos el caso de un paciente diagnosticado de enfermedad pulmonar obstructiva crónica (EPOC) tipo enfisema, que en TAC torácico mostraba una masa pulmonar derecha. Ante la duda de su etiología benigna o maligna, se realiza un estudio PET-18FDG. En éste se confirma la malignidad de dicha lesión, apreciándose simultáneamente un importante aumento de captación de la 18FDG que delimita la región costal bilateralmente y el diafragma, correspondientes a la musculatura respiratoria. Dicho hallazgo, aunque no es frecuentemente observable, ha de tenerse presente al interpretar las imágenes en pacientes que realizan esfuerzo continuado de la musculatura respiratoria para mantener el ritmo ventilatorio.
ABSTRACT
We present the case of a patient diagnosed of chronic obstructive pulmonary disease (COPD) emphysema type, showing a right lung mass oHn thorax CT. To evaluate eventual malignant etiology, a 18FDG -PET scan was performed. The study was consistent with a malignant lesion but showed also increased 18F-FDG uptake shaping the rib cage bilaterally and the diaphragm, corresponding to respiratory muscles. Although this pattern is not frequently found, we have to bear it in mind in the interpretation of images from patients with continuous effort of respiratory muscles in order to maintain the respiratory rhythm.
