“…described that the characteristic findings on a CT scan include lack of a discrete fat plane between the upper pole of the kidney and adrenal gland, with or without a contiguous well-defined lesion within the adjacent kidney. These findings are not specific, and it is difficult to exclude an invasive renal, adrenal, or retroperitoneal lesion in unilateral cases [ 11 ]. Two of the radiologically diagnosed cases were both bilateral, and as reported by Bamford et al ., the striking symmetry of the appearances and lack of suspicious uptake on positron emission tomography (PET)–CT helped to render the diagnosis [ 11 , 13 ].…”

Background Renal–adrenal fusion is a rare entity resulting from incomplete encapsulation of the adrenal gland and kidney. Only 18 cases have been reported in English literature to date. Case presentation Our patient is a 77-year-old African American female who presented with a systolic blood pressure of 200 mmHg. Computed tomography showed an enhancing 9 × 6 cm mass anterior and medial to the left kidney. The patient underwent a left adrenalectomy with partial nephrectomy. Gross and histologic examinations revealed an adrenal cortical adenoma and renal–adrenal fusion. Conclusion Renal–adrenal fusion may pose a diagnostic challenge, particularly when there is a concurrent adrenal adenoma. It is important to be aware of this uncommon anomaly to avoid misdiagnosis and overtreatment.

“…Second, "Adrenal-renal fusion", first described by Rokitansky in 1855 (7), could be divided into a "congenital" form when it is caused by failure of the retroperitoneal mesenchymal cells to stimulate adrenal capsule formation, or "acquired" form when it is a consequence of inflammation of the perirenal fat. Consequently the adrenal gland becoming fused with the renal parenchyma, and become anatomically indivisible from the kidney (8). Most ectopic adrenal tissue is located along the migration path of the urogenital system but it could be present also at the level of celiac axis, broad ligament, spinal cord and other retroperitoneal parenchymatous organs (9).…”

Introduction: Ectopic adrenal tissue in the kidney, including “Ectopic adrenal tissue” and “Adrenal-renal fusion”, is a rare event with a specific behavior which may be difficult to distinguish clinically from renal neoplasms. We performed a systematic review on ectopic adrenal tissue variants reported in the literature underlining its clinical aspects. Methods: Manuscripts which presented a case report or case series of ectopic adrenal tissue in the kidney were included even if published in original articles, reviews, or letters to the editor. A specific search on SCOPUS®, PubMed®, and Web of Science® database was performed. Only English language papers published in a period ranging between August 1991 and April 2020 were considered. Additionally, a case we had at our institution is described, and its characteristics are included. Data on clinical presentation, type of adrenal anomaly, location, anatomopathological and immune-histotype characteristics were collected. Results: We identified 888 manuscripts. Among these 29 were included in this systematic review. Overall, 39 patients with renal adrenal fusion or adrenal ectopia were considered. In most cases, the diagnosis was made incidentally, or following investigation for flank pain, abdominal pain, or endocrinological disorders. CT scan frequently identified a solid vascularized lesion that was difficult to distinguish from renal neoplasm. Adrenal fusion was mostly located at the level of the upper pole. Adrenal rest was found in the renal parenchyma, renal hilum, or retroperitoneum in close proximity to the renal peduncle. Often these ectopic adrenal tissue lesions follow a benign behavior and can be classified as functioning or non-functioning adenomas. Rarely, they may experience neoplastic degeneration. The most frequently positive markers were inhibin, vimentin, melan-A, synaptophysin and anti-p450 scc. Conclusions: Ectopic adrenal tissue in the kidney is a rare event with specific clinical characteristics that need to be identified in order to arrive at a correct diagnosis and carry out appropriate treatment management.
