Lipiodol marking for CT-guided radiofrequency ablation of adrenal aldosterone-producing adenomas: a case series.

ABSTRACT:

Background

Tumor visualization during computed tomography (CT)-guided radiofrequency ablation (RFA) of adrenal adenomas is often limited by the small size of the lesion and needle-induced artifacts. These limitations can impair accurate needle placement and increase the risk of incomplete ablation. This report shows four adrenal RFA procedures in which iodized oil (Lipiodol®) marking enhanced lesion visibility.

Case presentation

CT imaging and adrenal venous sampling showed unilateral right aldosterone-producing adenomas measuring 10-20 mm in patients with primary aldosteronism. Contrast enhancement of the nodules was confirmed via CT angiography after microcatheter insertion into the adrenal artery. Transarterial embolization was performed utilizing a 1:1 mixture of Lipiodo
