    Osteolytic metastasis detected by F18-FDG PET in a patient with lung carcinoma (WP)
    (2013-11) González Sistal, Ángel; Baltasar Sánchez, Alicia; Sánchez Salmón, Aida; Ruibal Morell, Álvaro
    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.

    Tribuna. Reorientar el diagnóstico
    (Unidad Editorial Revistas, 2007-04-13) González Sistal, Ángel
    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.
