Adrenal incidentaloma: A puzzle for clinician.

An adrenal incidentaloma (AI) is a puzzle for clinician. In the era of widespread use of CT and MRI, it is becoming an increasingly frequent diagnosis. A detailed list of investigations is ordered to diagnose pathology responsible for AI. Most likely etiology of AI is pathology of AI is benign non-functional adenoma. But looking to the need of specific preoperative preparation for functional adrenal adenoma and importance of early diagnosis in adrenal carcinoma, a complete workup is essential. CT scan of adrenals with contrast gives maximum information about nature of lesion. In general, a lesion more than 6cm or a functioning AI or tumor signal intensity of more than 10HU on unenhanced image, significant enhancement on contrast and deenhancement in signal intensity of less than 50% is suggestive of carcinoma and must be removed. Those AI which are left for observation, also needs regular testing and if found functional on subsequent follow-up or if their size enlarge, they must be removed.
