Article Abstract
Objective: To investigate the experience on diagnosis and treatment of multiple adrenal aldosterone-producing adenomas (APA).
Methods: Eighteen cases of multiple adrenal APA were analyzed retrospectively, which were admitted from October 1992 to April 2006.
Results: Adrenalectomy was performed for 4 cases of unilateral synchronous multiple APA, which were discovered with three adenomas by 3D-CT; bilateral tumor resection was performed for 6 cases of bilateral synchronous multiple APA. There were 8 cases of bilateral metachronous multiple APA, including 2 cases of ipsilateral recurrent adrenal APA after adrenal tumor removal, which underwent tumor resection. Another 6 cases were contralateral APA following adrenalectomy due to adrenal APA, and underwent tumor resection. After operation, the adrenal function seemed to be normal, and no recurrence had been found on follow-up.
Conclusions: Unilateral multiple synchronous APA require adrenalectomy. Tumor resection should be performed for bilateral or asynchronous APA, and it is very important to preserve healthy adrenal tissue as much as possible. 3D-CT has much value on diagnosis of small APA, unilateral multiple synchronous APA and ipsilateral recurrent adrenal APA.

Objective: The indication for laparoscopic partial adrenalectomy (LPA) in patients with primary aldosteronism due to aldosterone-producing adenoma (APA) remains controversial. This study aimed to determine the functional and surgical outcomes of LPA in this context.
Methods: This is a systematic review and meta-analysis.

Objective: This study aimed to investigate the risk factors associated with renal impairment among patients diagnosed with primary aldosteronism (PA).
Methods: This study enrolled 147 PA patients who were initially classified into hypokalemic (n=56) and normokalemic (n=91) groups according to serum potassium levels, followed by subgroup stratification using combined adrenal venous sampling (AVS) and computed tomography (CT) diagnostic data. For comparison, 280 patients diagnosed with essential hypertension (EH) served as the control group.

Purpose: Expression of CXC chemokine receptor 4 (CXCR4) has proved to be a valuable tool for guiding the diagnosis and treatment of aldosterone-producing adenoma (APA). In this study, we evaluated whether CXCR4 imaging with Ga-pentixafor PET/CT shows significant changes after superselective adrenal artery embolization (SAAE).
Methods: We prospectively recruited 25 patients with clinically diagnosed APA.

Primary aldosteronism (PA) is composed of different aldosterone-producing lesions including aldosterone-producing adenoma (APA), aldosterone-producing micronodules (APM), aldosterone-producing nodules (APN) and aldosterone-producing diffuse hyperplasia (APDH), all of which could result in hypertensive status and electrolyte imbalances. These aldosterone-producing lesions above are frequently accompanied by somatic mutations, including those of KCNJ5, CACNA1D, ATP1A1, and ATP2B3. APA is a neoplasm which frequently harbors KCNJ5 somatic mutations in tumor cells, especially those arising in East Asian patients.

Background: Primary aldosteronism (PA) is the leading cause of secondary hypertension. The 2022 WHO classification introduced the HISTALDO system, separating solitary aldosterone-producing adenomas/nodules (APA/APN; classical histology) from multiple nodules/micronodules (MAPN/MAPM; non-classical histology). Surgery often cures classical cases, while non-classical cases frequently recur.
