RESUMO
INTRODUCTION: Isolated cavernous and venous angiomas are common vascular cerebral malformations. The routine use of magnetic resonance imaging (MRI) in cerebral studies has shown their frequent association. OBJECTIVE: An analysis of the association characteristics of both lesions (cavernous and venous angiomas), and the relationships with localization, size, patient sex and the use of intravenous contrast material in the diagnosis with MR. METHODS: A retrospective analysis of the cerebral MRI studies of 37 patients with cavernous angiomas. Statistical relations were established with contingency tables and statistical methods of Pearson c2 and t of Student for independent samples. Results. 52 cavernous angiomas were identified in the 37 patients. No significant statistical differences were found that related the cavernous angioma size, localization or patient sex with the existence of an associated venous angioma. Only the administration of contrast material has shown a statistical significance for the diagnosis. CONCLUSIONS: The association of cavernous and venous angioma is frequent (30%). This association has prognostic implications, due to bleeding risk, and surgical as it is not recommended the resection of the venous anomaly due to the possible venous infarction. To detect venous angiomas is necessary the administration of contrast material.

Clinical staging is fundamental in lung cancer, as this descriptive system facilitates the transmission of the extension of the disease, provides prognostic information, helps in choosing the most appropriate treatment program, and provides a standardized system that enables the treatment outcomes of different series of patients to be compared. The most important technique for defining local, regional, and remote extension of the disease continues to be chest and abdominal CT. Functional imaging techniques play a complementary role that is becoming increasingly important in the noninvasive characterization of mediastinal lymph-node involvement.

La estadificación clínica del cáncer de pulmón es fundamental, ya que se trata de un sistema descriptivo que facilita la transmisión de la extensión de la enfermedad, aporta información pronóstica, ayuda a elegir el programa terapéutico más apropiado y proporciona un sistema estandarizado que permite la comparación de resultados terapéuticos entre series de pacientes. La técnica más importante para definir la extensión loco-regional y a distancia de la enfermedad, continúa siendo la tomografía computarizada torácica y abdominal. Las técnicas de imagen funcional tienen un carácter complementario que va ganando progresivamente protagonismo, principalmente en la caracterización no invasora de la afectación ganglionar mediastínica

La captación gástrica de 67Galio en pacientes con úlcera péptica ha sido descrita en numerosos trabajos de la literatura. Presentamos una captación focal yeyunal de 67Galio en un enfermo con gastrectomía total secundaria a un linfoma gástrico de células grandes tipo B, asociado a la existencia de una úlcera péptica benigna identificada por endoscopia. No hemos encontrado casos similares en la literatura referente al 67Galio. Se pretende realizar una revisión de las posibles causas de la captación gastrointestinal del 67Ga, así como de la utilidad de este radiotrazador en pacientes con linfoma gástrico (AU)

Post-radiotherapy cystitis is a high morbidity entity that involves difficult-to-treat haematurias and sometimes results in death. Percutaneous arterial embolization is an accepted approach for haemorrhages of pelvic origin. Selective, percutaneous embolization of both vesical arteries could be an alternative treatment to control severe haematurias caused by radiation. Presentation of our experience in two cases and proposal of this approach as a valid option in post-radiotherapy haemorrhagic cystitis.
