Benign Adrenocortical Tumors and the Detection of Nonadrenal Neoplasia

Table 4

Risk for benign abdominal neoplasia detected via abdominal cross-sectional imaging.

Benign abdominal neoplasm	Cases (adrenocortical tumor)	Controls (normal adrenal)	OR (95% CI)	AOR (95% CI)
n	400	400
Hepatobiliary hemangioma or adenoma	26 (6.5%)	19 (4.8%)	1.39 (0.76, 2.59)	1.30 (0.61, 2.79)
Hepatic cyst	109 (27.3%)	91 (22.8%)	1.27 (0.93, 1.75)	1.44 (0.98, 2.17)
Intraductal pancreatic mucinous neoplasm	34 (8.5%)	18 (4.5%)	1.97 (1.11, 3.62)	2.22 (1.11, 4.63)
Splenic hemangioma and cyst	16 (4.0%)	10 (2.5%)	1.62 (0.74, 3.75)	4.46 (0.92, 7.01)
Renal angiomyolipoma	9 (2.3%)	4 (1.0%)	2.28 (0.73, 8.46)	4.50 (0.94, 33.10)
Renal cyst	216 (54.0%)	167 (41.8%)	1.64 (1.24, 2.16)	1.25 (0.86, 1.81)

Note. The unadjusted and adjusted odds ratio for patients with benign adrenocortical tumors (cases) compared with those with normal adrenal glands (controls) are presented along with 95% confidence intervals for each benign abdominal neoplasm. AOR: adjusted odds ratio; adjusted for age, sex, race, smoking status, BMI, duration imaging interval, hypertension, hyperlipidemia, composite diabetes (diabetes or prediabetes), coronary artery disease, and myocardial infarction.
