title: Pseudotumours and insignificant tumours in US and CT examinations of the adrenal glands.
abstract: Pseudotumours encountered in US and CT examinations of the adrenal glands over 2 years are reviewed. 12 pseudotumours were detected in US, 1 in the right adrenal gland and 11 in the left, while 2 pseudotumours were seen in the CT. The former were due to splenic lobulation in 4 patients, accessory spleens in 4, splenic cyst in one, renal cysts in 2 and the bowel contents in one, and the latter to the stomach and an accessory spleen (both of these CT examinations were technically unsuccessful). The 7 benign, non-functioning adenomas detected in CT and causing problems of differential diagnosis were also collected over the same period. A comparison of the US findings for 30 malignant adrenal tumours and the above pseudotumours revealed no essential differences, nor did a comparison of the benign non-functioning adenomas and small malignant adrenal tumours.
