Two cases of nonmalignant adrenal masses with prolonged T2 relaxation time and increased adrenal/liver signal ratios are reported. These two cases, one a functioning adenoma with small areas of hemorrhage and the other tuberculosis, emphasize that increased signal intensity in an adrenal mass on T2-weighted images is not always due to malignancy or a pheochromocytoma. While the signal characteristics of an adrenal mass are useful in distinguishing malignancy or pheochromocytoma from benign adenomas, other studies (such as computed tomography for the detection of hemorrhage), clinical evaluation, and percutaneous biopsy remain useful in the investigation of an adrenal mass.
报告了两例肾上腺非恶性肿块，其T2弛豫时间延长，肾上腺/肝脏信号比增加。这两例病例，一例是有小面积出血的功能性腺瘤，另一例是结核病，强调了肾上腺肿块在T2加权图像上信号强度增加并不总是由于恶性肿瘤或嗜铬细胞瘤。虽然肾上腺肿块的信号特征有助于将恶性肿瘤或嗜铬细胞瘤与良性腺瘤区分开来，但其他检查（如用于检测出血的计算机断层扫描）、临床评估和经皮活检在肾上腺肿块的检查中仍然有用。
