Adrenal hemangiomas versus adrenal pheochromocytomas with radiologic-pathologic correlation

Area of Science:

• Radiology
• Endocrinology
• Oncology

Background:

• Adrenal hemangiomas are rare benign vascular tumors.
• Their imaging features can overlap with malignant adrenal neoplasms, posing diagnostic challenges.
• Distinguishing them from pheochromocytomas is crucial for appropriate patient management.

Purpose of the Study:

• To present the characteristic imaging findings of adrenal hemangiomas.
• To differentiate adrenal hemangiomas from pheochromocytomas and other adrenal tumors with similar appearances.
• To share a clinical case illustrating this diagnostic dilemma.

Main Methods:

• Review of imaging characteristics of pathologically confirmed adrenal hemangiomas.
• Comparison with imaging features of pheochromocytomas and other adrenal neoplasms.
• Discussion of radiologic-pathologic correlation.

Main Results:

• Adrenal hemangiomas exhibit specific imaging patterns on CT and MRI.
• Key differentiating features from pheochromocytomas include enhancement patterns and lesion morphology.
• Understanding these nuances aids in accurate diagnosis.

Conclusions:

• Adrenal hemangiomas, though rare, require careful radiologic assessment.
• Characteristic imaging features can help distinguish them from more common adrenal tumors like pheochromocytomas.
• Accurate differentiation prevents misdiagnosis and guides clinical decision-making.
