RESUMEN
La 18F-FDG PET/TC tiene un papel importante en la evaluación de los tumores de la vaina nerviosa periférica, especialmente para determinar la posibilidad de malignidad y el sitio idóneo para la toma de biopsia. Se expone el caso de una mujer de 34 años de edad con diagnóstico de tumor de vaina nerviosa periférica, localizado en el mediastino posterior, que generó síndrome de vena cava superior y síndrome de Horner. Se realizó 18F-FDG PET/TC para hacer el diagnóstico diferencial entre benignidad y malignidad. Se encontró masa heterogénea con áreas hipermetabólicas que alcanzaban un SUVmax (valor de captación estándar máximo) de 8,5, hallazgos que sugerían origen maligno con diferentes grados de diferenciación. La biopsia de los lugares con mayor metabolismo arrojó el resultado de tumor maligno de vaina nerviosa periférica.
ABSTRACT
18F-FDG PET/CT is a useful imaging modality in the diagnosis and follow-up of peripheral nerve sheath tumors, especially in the assessment of tumor grade and biopsy guidance. The case of a 34-years-old woman diagnosed with peripheral nerve sheath tumor located in the posterior mediastinum that generated superior vena cava syndrome and Horner syndrome is presented. 18F-FDG PET/TC was performed to assess the possibility of malignancy. An 18F-FDG PET/CT was performed to determine whether it was benign or malignant, a heterogeneous mass with hypermetabolic areas with a maximum standardized uptake value (SUVmax) of 8.5 was found, and suggested malignancy with multiple grades of differentiation. A tumor biopsy from the region of higher metabolism was recommended with pathology result of malignant peripheral nerve sheath tumor.
