Adrenal calcification

Adrenal calcification is not a rare finding in healthy asymptomatic people, and is usually the result of previous haemorrhage, or tuberculosis. Addison's disease patients only occasionally have calcification.

Radiographic features

This is best assessed on CT where simple adrenal calcification can also be differentiated from a calcified adrenal mass or lesion. CT also for simultaneous characterisation of any underlying lesions with size, density, enhancement and washout.

In children neuroblastoma has reported as the commonest calcifying adrenal mass 4. In adults calcified simple cysts have been reported as common adrenal masses, characteristically showing peripheral curvilinear calcification.

Post-haemorrhage calcification is usually seen after the initial adrenal haematoma has resolved and, hence, is not usually seen with an adrenal lesion. However, adrenal metastases such as from bronchogenic tumours can present with haemorrhage, making the diagnosis challenging.
