La sialoadenitis aguda es una reacción adversa muypoco frecuente a la administración de contraste yodado,que causa una inflamación autolimitada de las glándulassalivales. Su patogenia no está bien establecida, aunque la insuficiencia renal puede ser un factor de riesgo.El diagnóstico es inicialmente clínico, y debe realizarsediagnóstico diferencial con angioedema, infecciones y litiasis. Ningún tratamiento o profilaxis ha demostrado beneficio hasta el momento. Aunque tiene buen pronóstico,en algunos casos se han descrito complicaciones.Presentamos el caso de un varón de 68 años que presentó inflamación de las glándulas salivales submandibulares tras la realización de una tomografía computariza-da abdominal con administración de contraste yodado.Dado el uso creciente de contrastes yodados en pruebasde imagen y técnicas intervencionistas, es importante conocer posibles reacciones adversas como esta entidad.(AU)
Acute iodide sialadenitis is a rare adverse reactionto iodinated contrast that causes self-limited salivarygland swelling. Its pathogenesis is still unclear, althoughkidney failure may be a risk factor. The diagnosis isinitially clinical but angioedema, infections and lithiasis should be included in the differential diagnosis. Notreatment or prophylaxis was proven to be beneficial.Although its prognosis is benign, associated complications have been reported.We report a case of 68-year-old man with swelling ofthe submandibular salivary glands after the administration of iodine-based contrast media during an abdomi-nal computed tomography examination. Because of thewidespread use of iodinated contrast enhanced imaging and interventional techniques, clinicians should beaware of this issue.(AU)

Objetivos. Evaluar la utilidad de la cistoscopia virtual (CV) realizada junto con la urografía por tomografía computarizada (URO-TC) en pacientes en estudio por hematuria macroscópica o en seguimiento por antecedente de cáncer de vejiga tratado, y comparar los resultados con los obtenidos con la técnica de referencia (uretrocistoscopia óptica [UCO]). Material y métodos. Estudio retrospectivo de 117 pacientes derivados para realización de CV y URO-TC desde el Departamento de Urología entre mayo de 2014 y mayo de 2015. Dichos pacientes presentaban hematuria macroscópica o habían sido tratados previamente por cáncer de vejiga y estaban bajo seguimiento periódico. Fueron sometidos a CV tras la distensión de la vejiga con aire. Los resultados obtenidos fueron comparados con los de la UCO realizada no más de una semana después. Resultados. La sensibilidad y la especificidad global de la CV fueron del 81,8% y el 92,1%, respectivamente. La tasa de hallazgos críticos (que comprometían la vida del paciente) detectados en la URO-TC realizada junto a la CV fue del 12%, similar a la de otros estudios. Conclusión. La CV es una técnica útil en el diagnóstico y el seguimiento del cáncer de vejiga, con buena correlación con la UCO. Sus principales limitaciones son la imposibilidad de toma de biopsia y la capacidad para detectar lesiones eritematosas de mucosa. El empleo concomitante de la URO-TC aporta hallazgos incidentales críticos, pero el incremento en la dosis de radiación no justifica el empleo combinado de ambas (AU)
Objectives. To evaluate the utility of virtual cystoscopy (VC) performed with CT urography in patients being studied under gross hematuria or patients being followed-up after a previous bladder cancer and compare the results with those obtained with gold standard technique (optical cystoscopy). Methods. Retrospective study of 117 patients who were referred for VC by the Urology Department between May 2014 and May 2015. Those patients presented with gross hematuria or they were previously treated patients from bladder cancer being followed up. These patients were evaluated with MDCT and virtual cystoscopy after distending the bladder with air. The results were compared with those obtained with optical cystoscopy which was performed no more than a week after. Results. The global sensitivity and specificity of VC were 81,8 and 92,1%. Aditional findings detected in CT urography were an aortic dissection, urinary lithiasis and colonic metastasis. Conclusion. VC seems an useful technique in the diagnosis and follow-up for bladder cancer with a good correlation with OC. The main limitations are the impossibility of biopsy during the procedure and the detection of erythematous lesions. Collateral findings can be detected performed with CT urography although the high radiation exposure does not recommend their combined use (AU)
