“…The MRI findings in our case were also compatible with those of retroperitoneal schwannomas, which typically show hypointensity on T1-weighted images and hyperintensity on T2-weighted images ( 6 ). Cystic degeneration can occur in schwannomas; however, the finding is not specific to adrenal schwannomas ( 7 ). Up to 70% of ACAs are lipid-rich and show low CT attenuation values of ≤10 HU.…”

Schwannoma is a common mesenchymal neoplasm; however, adrenal schwannoma is rare, and it is frequently misdiagnosed as adrenal cortical adenoma. We herein report a 91-year-old Japanese man with right adrenal schwannoma that was pathologically diagnosed after adrenalectomy. To our knowledge, this is the first case of adrenal schwannoma in the oldest patient and with the longest follow-up period reported, including radiological images from 10 years earlier.

“…1 Verocay was the first to describe them in 1908 and Antonini (1920) subclassified these tumors as the ones with hyalinization and interstitial fibrosis. 3 Long standing tumors also show degenerative changes in the form of either cystic changes, fibrosis, calcification or hyalinization and have a better outcome. 4 Schwannomas can be malignant as well which often are multiple and associated with von-Recklinghausen’s disease in upto 18% of the cases.…”

“…8 Whereas T1 and T2 weighted images on magnetic resonance imaging (MRI) show low signal and high signal intensity respectively. 3 On histopathological examination, they consist of Antoni A and B cells which consist of high cellularity component and pure myxoid component respectively and stain positively for S100. Because of these features it is sometimes difficult to distinguish them from neurofibromas.…”

Schwannoma of the adrenal gland is very rare, comprising 0.2% of adrenal tumors, presenting usually as non-specific abdominal pain. We report such a rare case in a 50-year-old female. Her only complaint was right lumbar pain. Ultrasonography (USG) and computed tomography (CT) both showed a supra renal cystic mass most likely of adrenal origin. Excision of mass was performed. Post-operative course was uneventful. Histopathology showed a benign tumor of Schwann cell origin. Usually, pre-operative imaging including CT and magnetic resonance imaging (MRI) are inconclusive and diagnosis has to be confirmed on histopathology.

“…Furthermore, the schwannomas on MRI appear as a well-circumscribed mass with cystic degenerative changes with low signal intensity on T1-weighted images and heterogeneous high signal intensity on T2-weighted images. However, these imaging characteristics are not specific [12].…”

Schwannoma is a benign neurogenic tumor originating from the neural sheath of Schwann cells. It is an extremely rare cause of adrenal adenoma which is very difficult to diagnose preoperatively. We report the case of a right adrenal schwannoma discovered incidentally in a 62-year-old woman during evaluation of right flank pain. The biochemical and hormonal evaluations were unremarkable. Radiological examination revealed a 4.8 cm lesion keeping with right adrenal adenoma. Surgical intervention was done due to the large size of the tumor, and laparoscopic right adrenalectomy was performed. The postoperative course was uneventful. Histological examination established the diagnosis of schwannoma, which was further confirmed by immunohistochemical staining. In conclusion, adrenal schwannoma is extremely rare and can be misdiagnosed as nonsecreting adrenal adenoma. Complete surgical excision is the treatment of choice which is associated with favorable outcome and also helps in clarifying its histopathological nature.
