Resumo

Relata-se um caso de um paciente com queixa principal de dor lombar à esquerda, portador de angiomiolipomas renais (AMLRs) bilaterais, com a lesão mais volumosa de 6,2 cm em seu maior diâmetro, submetido a tratamento endovascular por embolização arterial superseletiva com microesferas. Os AMLRs são tumores benignos raros. A maioria é esporádica, enquanto uma minoria está associada à Esclerose Tuberosa Complexa (ETC). Os AMLRs maiores do que 4 cm devem ser tratados devido ao maior risco de complicações, principalmente hemorrágicas. A embolização arterial seletiva (EAS) é um tratamento efetivo e seguro para os AMLRs.

Abstract

We report a case of a patient with a major complaint of left lumbar pain, diagnosed with bilateral renal angiomyolipomas (AMLRs), with the most voluminous lesion of 6.2 cm in its largest diameter, underwent endovascular superselective arterial embolization with microspheres. The AMLRs are rare benign tumors. Most are sporadic, while a minority is associated with Tuberous Sclerosis Complex (ETC). The AMLRs larger than 4 cm must be treated due to higher risk of complications, especially hemorrhagic. A selective arterial embolization (EAS) is an effective and safe treatment for AMLRs.
