Abstract

The coexistence of different bone diseases in the same patient involves a complex differential diagnosis. A patient is presented who was studied due to a renal mass that showed many sclerotic lesions in spine and limbs in conventional radiology and CT. These lesions were evaluated with 99mTC-HDP bone scintigraphy and 18F-FDG PET/CT, which helped to obtain the definitive pathological diagnosis of osteopoikilosis (OP) co-existing with gastric cancer bone metastases. Of the different imaging scans performed, bone scintigraphy was particularly relevant due to its ability to discriminate between benign and metastatic bone disease.

Resumen

La coexistencia de distintas alteraciones óseas en un mismo paciente es un hallazgo que plantea un diagnóstico diferencial complejo. Presentamos el caso de una paciente en estudio por una lesión renal, que en la radiografía convencional y en la TC presentó múltiples lesiones esclerosas en columna y extremidades, que se valoraron mediante gammagrafía ósea con 99mTc-HDP y 18F-FDG PET/TC, obteniéndose el diagnóstico definitivo mediante la anatomía patológica de coexistencia de metástasis óseas por cáncer gástrico y osteopoiquilia (OP). Entre las técnicas de imagen realizadas, la gammagrafía aportó el mayor rendimiento diagnóstico por su capacidad de discriminación entre enfermedad ósea benigna y metastásica.
