Aquest informe tècnic mostra la classificació, incidència, característiques i diagnòstic dels tumors ossis primaris i secundaris metastàsics més freqüents a partir de 145 radiografies digitalitzades
This technical report introduces the classification, incidence and diagnosis of common primary bone tumors. A set of 145 digitized radiographs were characterized. The differences between healthy bone and
bone tumors were studied by using image processing and analysis. This work shows the usefulness of our method to contribute in the differential diagnosis between healthy and pathological bone when the exploration is insufficient.

Las técnicas de diagnóstico por imagen han revolucionado muchas especialidades, como la oncología, donde su uso ha permitido reducir la morbi-mortalidad de lesiones detectadas precozmente. Sin embargo, ni todas las técnicas ni todos los tumores son iguales.

We present a 53-year-old man with a vocal cord paralysis observed as a primary manifestation of lung carcinoma. Tc-99m MDP whole body bone scan were performed and resulted a normal scintiscan. The bone scan does not revealed suspicious foci of uptake. The possibility of bone metastasis was taken into consideration. A whole body F18-FDG-PET scan showed intense uptake in the left upper lung corresponding to the primary tumor. A bronchial biopsy confirmed infiltration by small cell lung carcinoma (SCLC). SCLC is composed of poorly differentiated, rapidly growing cells with disease usually occurring centrally rather than peripherally. It metastasizes early. The whole-body F18-FDG-PET scan clearly demonstrated a focus of increased uptake in the second lumbar vertebral body suspicious for osteolytic metastasis. A lytic bone metastasis was confirmed by MRI. The patient then received therapy and underwent follow up abdominal CT. The scan showed blastic changes in the L2 vertebra suggesting response to treatment.
