ABSTRACT
La linfogammagrafía es una técnica ampliamente aceptada para la detección selectiva del ganglio centinela en el melanoma maligno. Presentamos el caso de un paciente intervenido de un melanoma inguinal y que fue remitido al Servicio de Medicina Nuclear para una linfogammagrafía preoperatoria. Existieron problemas técnicos para la detección del ganglio centinela debido a su cercanía con los puntos de inyección. Nosotros planteamos como objetivo la posibilidad de realizar una linfogammagrafía intraoperatoria como técnica válida y de ayuda en casos como el que describimos
Lymphoscintigraphy is a widely accepted method used to detect selectively the sentinel node in malignant melanoma. This is the case report of a patient who was operated on for an inguinal melanoma and who was referred to the Nuclear Medicine Section for preoperative lymphoscintigraphy. There were technical problems for sentinel node detection due to the proximity of injection points. We aimed to know the possibility to perform an intraoperative lymphoscintigraphy as a valid and useful technique in cases as this one

We report a case of a 50 year old man referred to our department with a history of mild cough, dyspnea and dysphagia. The thoracic CT scan showed a large solid mass in the anterior mediastinum, corresponding to the findings in the chest radiographs.A 67Ga scintigraphy was performed and showed high pathological accumulation in the anterior mediastinum. A subsequent fine needle aspiration biopsy (FNAB) showed the presence of malignant cells, suggesting thymic carcinoma. Although this type of tumour is uncommon, it should be taken into account in order to establish the differential diagnosis of gallium-avid mediastinal masses.

Presentamos el caso de un varón de 50 años, remitido a nuestro departamento con una historia de tos, disnea y disfagia leves. La TAC torácica mostró una gran masa sólida en mediastino anterior, coincidente con los hallazgos en la radiología de tórax. Se realizó una gammagrafía con 67Ga, presentando un intenso acúmulo patológico en mediastino anterior. Posteriormente se practicó una punción-aspiración con aguja fina (PAAF), con presencia de células malignas sugestivas de carcinoma tímico. Aunque este tipo de tumor es poco frecuente, debería ser tenido en cuenta para establecer el diagnóstico diferencial de las masas mediastínicas captantes de 67Ga (AU)
