There is no definitive figure for the size of a non-functioning adrenal adenoma, which is often 3 to 5 cm in diameter, but may be larger or smaller.
Adrenal adenomas are benign tumors that occur in the adrenal cortex and can be functional or nonfunctional. Nonfunctional adrenal adenomas have a higher incidence and patients are usually asymptomatic. However, there is no definite figure for its size, which often ranges from 3 to 5 cm or even larger, depending on the individual, and no generalization can be made.
Usually, for smaller adrenal gland adenomas, there are no obvious symptoms, so you can choose to observe for the time being. For larger adrenal adenomas, they may cause pressure symptoms (e.g. frequent urination, increased nocturia, abdominal pain, lumbago, etc.), and surgical resection should be considered as a treatment option.
It is recommended that patients undergo further examination to clarify the volume of the adenoma, and the doctor will consider the treatment plan according to the actual situation.
