Existen 2 tipos de TIA, con mecanismos fisiopatológicos diferentes; es importante distinguir entre ellos ya que el tratamiento es diferente. Sin embargo esta distinción en ocasiones es complicada. Se presenta el caso de una paciente de 81 años con antecedente de leucemia mieloide aguda, que cursó con aumento de volumen de cuello 48 h después de haber sido egresada por un cuadro de fibrilación auricular (FA) tratada con infusión de amiodarona. Bioquímicamente con tirotoxicosis y reaparición de la FA. Se sospechó de una TIA. Para enfocar el tratamiento es indispensable distinguir entre los 2 tipos de tirotoxicosis inducida por amiodarona. El ultrasonido Doppler y el gammagrama tiroideo pueden ser útiles para establecer el diagnóstico. Se deben considerar las comorbilidades de los pacientes, así como los efectos secundarios al momento de establecer el tratamiento.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Amiodarone induced thyrotoxicosis (AIT) appears on the 5-12% of patients, it potentially can exacerbate a cardiac illness, leading to an increase in the morbility/mortality of patients. Two types of AIT exist, each one with a different etiology. It is important to distinguish between them to be able to establish a treatment. However, sometimes it can be quite difficult. Case Report: An 81 year-old woman, with a history of acute myelod leukemia, showed up with thyroid enlargement at the ER. She was discharged 48 h earlier, after an atrial fibrillation (AF) episode which was controlled with amiodarone IV infusion. Because the biochemical diagnosis of thyrotoxicosis and reaparition of AF,an AIT was suspected. To be able of distinguishing between the two types of AIT is essential to establish a treatment. The use of a thyroid doppler sonography and a thyroid scintigraphy is helpful. The comorbidities of the patient and the possible side effects should be taken into account when deciding the treatment.]]></p></abstract>
