Article Abstract
Objective: To report a case of oncocytoma, a relatively rare adrenal tumor, which most commonly is detected as an adrenal incidentaloma.
Methods: We present a case report, including laboratory, imaging, and pathologic findings, of a 47-year-old obese woman who had hypertension and an incidentally found large, left adrenal mass.
Results: On the basis of the hormonal evaluation, this mass was a nonsecreting adrenal tumor, which histologically proved to be an oncocytoma with borderline malignant characteristics. A collective analysis of the few cases of adrenal oncocytoma published in the medical literature showed that our case corresponded to the previously published cases in preponderant location (left side) as well as the general size (11.4 cm in the largest dimension) and weight (372 g).
Conclusion: Adrenal oncocytoma should be included in the differential diagnosis of adrenal incidentalomas, especially if large tumors are detected. In addition, a longterm follow-up is suggested because there are no certain clues about the true potential of this tumor.

A woman in her 70s presented with features of hyperandrogenism including clitoral enlargement and deepening of her voice. Biochemical investigations revealed raised plasma androgens and urinary androgen metabolites and imaging findings showed a highly F-18 fluorodeoxyglucose (FDG)-PET avid left adrenal tumour initially suspected to be a malignant adrenocortical carcinoma (ACC). She subsequently underwent an uncomplicated laparoscopic adrenalectomy where complete resection of her tumour was achieved.

Article Synopsis
- The increased use of imaging techniques has led to more frequent detection of incidental findings in the kidneys and adrenal glands, often referred to as incidentalomas, which are commonly encountered by general practitioners.* -
- This review provides guidelines for managing these renal and adrenal masses, highlighting that renal lesions are seen in about 14% of CT scans and should be assessed using the Bosniak classification for cystic lesions.* -
- For renal cell carcinomas larger than 4 cm or showing symptoms, active treatment is recommended, while adrenal lesions require functional testing, with specific screening tests indicated based on clinical signs such as hypertension.*

Article Synopsis
- - Pheochromocytomas are uncommon tumors in the adrenal medulla, making up 10% of adrenal cancers, with oncocytic variants being especially rare, having only 150 documented cases.
- - The case study highlights a 60-year-old woman with a non-functional adrenal tumor, showcasing the complexities of diagnosing these tumors.
- - The report stresses the need for thorough histological and immunohistochemical examinations to accurately identify these rare tumors and avoid misdiagnosis.

Oncocytoma is a tumour that predominantly occurs in the kidneys and salivary glands. Only approximately 200 cases have been reported to be of adrenal origin to date, and only a few reports about its radiological findings have been published so far. Herein, we present the CT and MRI findings of an adrenal oncocytoma observed in a patient suspected of having mitochondrial abnormalities, along with the pathological findings.

Oncocytic adenomas are rare benign tumors that typically originate in organs such as the kidneys, thyroid, parathyroid, salivary glands, or pituitary gland. Oncocytic adenoma of the adrenal gland is extremely rare. It often shows heterogeneous, nonspecific features on anatomic imaging, as well as high F-FDG avidity despite its benign nature.
