Computed tomography in adrenal tumors.

N R Dunnick, E G Schaner, J L Doppman

    AJR. American Journal of Roentgenology
    |January 1, 1979
    PubMed
    Summary

    Computed tomography (CT) accurately identifies most adrenal tumors, including adenomas and carcinomas, aiding in diagnosis. While effective for many lesions, CT showed limitations in detecting pheochromocytomas.

    Area of Science:

    • Radiology
    • Endocrinology
    • Oncology

    Background:

    • Adrenal lesions encompass a range of benign and malignant conditions.
    • Accurate localization and characterization of adrenal masses are crucial for appropriate patient management.
    • Computed tomography (CT) is a widely used imaging modality for evaluating the adrenal glands.

    Purpose of the Study:

    • To assess the efficacy of computed tomography (CT) in evaluating various adrenal lesions.
    • To determine CT's accuracy in identifying different types of adrenal tumors and hyperplasia.
    • To evaluate CT's utility in differentiating adrenal adenomas from hyperplasia.

    Main Methods:

    • Computed tomography (CT) was performed on 26 patients with adrenal lesions.
    • Surgical confirmation was obtained in 22 patients; clinical confirmation in 4 patients.
    • Lesions evaluated included aldosterone-producing adenomas, cortisol-producing adenomas/carcinomas, adrenal hyperplasia, metastases, and pheochromocytomas.

    Main Results:

    • CT correctly identified 7 out of 9 aldosterone-producing adenomas.
    • CT accurately identified all 4 cortisol-producing adenomas and 5 cortisol-producing carcinomas.
    • CT visualized prominent but normally shaped glands in adrenal hyperplasia and identified adrenal metastases.
    • CT detected only 1 of 2 pheochromocytomas.

    Conclusions:

    • Computed tomography (CT) is a valuable noninvasive tool for localizing adrenal tumors.
    • CT can assist in differentiating adrenal adenomas from adrenal hyperplasia.
    • CT demonstrates high accuracy for certain adrenal tumors but has limitations for others, such as pheochromocytomas.
