Size Matters: Detecting Pheochromocytoma

The detection of lipid pore adrenal masses, particularly pheochromocytomas, is significantly influenced by the size of the mass. Masses smaller than 1.5 centimeters may yield normal lab results, thus complicating diagnosis as biochemical detection requires larger tumors. With the rise in cross-sectional imaging, there is an increased likelihood of encountering asymptomatic and pre-biochemical pheochromocytomas. Consequently, it is essential to maintain a high index of suspicion for pheochromocytoma based on imaging characteristics, especially if the lipid pore mass shows enhanced visibility after contrast administration.
