With the use of ultrasound , CT and MRI scanning, adrenal tumors are being discovered at an earlier stage. In fact, a diagnostic dilemma occurs when an adrenal mass is discovered on a routine scanning. Most of these masses are fortunately benign adenomas, but a diagnostic work-up should be done to discover whether the mass produces hormones . After an interval, a repeat scan will detect whether the mass is growing; if it is, the presence of cancer must be considered.
Pheochromocytomas can occur outside the adrenal gland and may be difficult to find. An extensive search is appropriate for anyone with typical signs and symptoms, even if scans of the adrenals are negative. Some of these tumors can be identified by nuclear medicine scans using MIBG.
Blood and Other Tests
• Endocrine studies (blood and urine tests).
• Serum chemistry profile.
Imaging
• CT, MRI, I-131-MIBG or ultrasound scans.
• Chest x-ray or bone scan to detect metastatic lesions.
