ABSTRACT
Lung cancer is one of the most common malignant diseases. Many tests and techniques are used in the staging of this disease, including positron emission tomography. This is probably the most recently introduced test and is capable of providing information on all the structures affected by malignancy. We present a case of a false positive result due to increased splenic uptake of the tracer.

OBJECTIVE: Chronic hematoceles are rare scrotal masses. Most of them include trauma, torsion, tumor, and surgery as possible causes. We describe the case of an old diabetic patient, who is attended for presenting a marked increase in size of the right hemiescrotum and pain. METHODS: We described computed tomography and sonographic findings. RESULTS/CONCLUSIONS: Frequently, a varicocele is an associated finding. Presumibly, minor trauma results in rupture of dilated vessels. In sonographic exploration, they have a more complex heterogeneous appearance with echogenic debris and septations. Most hematoceles spontaneously resolve with conservative therapy.

Objetivo: Los hematoceles crónicos son una causa infrecuente de masa escrotal. Se asocian en la mayoría de los casos a traumatismos, cirugía previa, diabetes, neoplasias, torsión testícular o enfermedad arterioesclerótica. Presentamos el caso de un paciente de edad avanzada, diabético, que consulta en urgencias por presentar desde hace tres meses un cuadro de aumento de tamaño del hemiescroto derecho y supuración, así como fiebre y dolor. Método: Se le realiza ecografía y una tomografía (TC) abdomino-pélvica con extensión inguino-escrotal describiéndose los hallazgos encontrados en las pruebas de imagen y que nos pueden ayudar a caracterizar esta entidad clínica. Resultados/Conclusiones: El mecanismo de producción es el resultado de traumas menores sobre vasos dilatados. Suelen ir acompañando a procesos agudos como epididimitis y torsión testicular. Se presentan ecográficamente como masas heterogéneas con septos, tabiques y loculaciones en su interior. Muchos de ellos se resuelven con tratamiento conservador (AU)

Lung cancer represents one of the most common malignant diseases. Many investigations are used in the staging study including, most recently, PET. We present a case of cystic cerebral metastases (with no oedema) from a small cell carcinoma which were not detected by PET.
