NP-59 SPECT/CT Imaging in Stage 1 Hypertensive and Atypical Primary Aldosteronism: A 5-Year Retrospective Analysis of Clinicolaboratory and Imaging Features
Figure 1
A 56-year-old male patient (case 4) with stage 1 hypertension for 3 years presents with atypical triad of PA and normokalemia. Contrast adrenal CT (b) shows a 1.2 cm nodular lesion in left adrenal gland (arrow). NP-59 96 h planar posterior imaging (b) indicates no radiotracer uptake within either adrenal gland, but fused SPECT/CT (c) indicate intense uptake in the left adrenal (arrow), consistent with left adrenal aldosteronism. His hypertension cured following left adrenalectomy.
