ABSTRACT
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)
