RESUMO
47 year old woman affected by myositis ossificans, with muscular calcifications in her evolution. Bone scintigraphy showed increased polyfocal activity as well as uptake of different intensity in soft tissues. The bone scintigraphy allows for early identification of ossification areas in soft tissues, as it can even detect injuries earlier than that observed with other image techniques. It is considered to be very useful in the diagnosis and establishment of the extension of the process, as well as follow-up.

Young male patient clinically and radiologically diagnosed of a tumour in IX right rib. A subsequent study with bone scintigraphy showed other areas of focal uptake in the skull, ribs and left trochanterian region. The biopsy of the costal lesion showed a fibrous dysplasia in the clinical context of a McCune-Albright syndrome. The convenience of using complementary imaging techniques is discussed to establish adequate therapeutic behavior.

OBJECTIVE: This study was designed to assess the diagnostic accuracy of single photon emission computed tomography with Tl-201 (SPECT Tl-201) to establish the tumoral or non-tumoral nature of brain space occupying lesions in comparison with usual diagnostic techniques. MATERIAL AND METHODS: The study population consisted of 37 patients, 24 men (64.9 %) and 13 women (35.1 %), mean age 48 +/- 16 years. After establishing the clinical and radiological diagnosis of brain lesion, all patients underwent SPECT Tl-201, evaluating it only by subjective analysis and blinded to neuroestructural techniques. After surgical resection all patients were evaluated anatomopathologically to establish the histologic nature. RESULTS: The sensitivity of SPECT Tl-201 (0.87) was higher than standard neuroimaging techniques (0.78). Specificity (0.43), positive (0.87) and negative (0.43) predictive values of SPECT were similar to neuroestructural procedures (MRI and CT scan) with 0.43, 0.82 and 0.38 values. Tumoral disease prevalence was 0.81. Neuroestructural procedures were non-conclusive in 18.9 % of the studies. No non-conclusive results were obtained with SPECT Tl-201. CONCLUSIONS: SPECT Tl-201 is a diagnostic procedure of high sensitivity to establish the tumoral nature of brain lesions, with poor specificity, similar to structural X-ray techniques.

Se presenta el caso clínico de una mujer de 47 años de edad afectada de miosotis osificante, en evolución con calcificaciones musculares. La gammagrafía ósea mostró aumento de actividad polifocal así como depósitos de distinta intensidad en tejidos blandos. La gammagrafía ósea permite una identificación precoz de áreas de osificación en tejidos blandos, pudiendo incluso detectar lesiones de forma más temprana que las observadas con otras técnicas de imagen, considerándose de gran utilidad en el diagnóstico y establecimiento de la extensión del proceso, así como en su control evolutivo

Paciente varón joven diagnosticado clínica y radiológicamente de tumoración en IX arco costal derecho. Un estudio posterior con gammagrafía ósea puso de manifiesto la existencia de múltiples áreas de captación a nivel de cráneo, parrilla costal y territorio trocantéreo izquierdo. La biopsia de la lesión costal ofreció el resultado de una displasia fibrosa, interpretable en el contexto clínico de un Síndrome de McCune-Albright. Se discute la conveniencia de utilizar técnicas diagnósticas de imagen de forma complementaria para poder adoptar una conducta terapéutica adecuada (AU)
