The authors report their experience of 34 benign and 17 malignant tumo
urs of the adrenal cortex. Both occurred more frequently in women (79.
4 % of cortical adenomas and 70.6 % of adrenocortical carcinomas). Mor
eover, females were significantly younger (average age : adenomas: fem
ales 44.9 years and males 54.4 years, adrenocortical carcinomas: femal
es 34.1 years and males 58.3 years). Some tumours presented in the for
m of increased hormone production, while others were hormonally inacti
ve and did not cause clinical signs until later. Pain was the first sy
mptom in the cases of malignant adrenocortical tumours. Adenomas occur
red as frequently twice in the left adrenal gland (24 versus 12), wher
eas carcinomas were more than twice are frequent on the right (10 vers
us 7). Ultrasonography and CT were appropriate and fully sufficient me
thods for the diagnosis of adrenal tumours. Arteriography was valuable
in the differential diagnosis of large upper abdominal masses when th
e organ of origin could not be identified by CT and for determination
of anatomic conditions and subsequent surgical tactics. For small tumo
urs of the adrenal cortex, the classic lumbar approach through the bed
of the resected eleventh rib is adequate. For larger tumours, extende
d lumbotomy, laparotomy or thoracotomy is necessary.
