Schwannomas are rare tumors, usually benign, originating from the Schwann sheath of the peripheral or cranial nerves. They are an extremely uncommon cause of adrenal incidentaloma. It is difficult to diagnose adrenal schwannoma preoperatively by imaging alone due of their aspect suspect on it. We report a case of adrenal mass discovered incidentally in a 41 years old patient who presented an atypical abdominal pain. Biological assessment was unremarkable, and imaging studies did not show strict imaging criteria for a typical adenoma. A surgical excision of the adrenal incidentaloma was decided. Histopathological examination and immunohistochemical staining of the excised specimen revealed a benign schwannoma.
施万细胞瘤是罕见肿瘤，通常为良性，起源于周围神经或颅神经的施万鞘。它们是肾上腺偶发瘤极其罕见的病因。由于其在影像学上表现可疑，仅通过影像学很难在术前诊断肾上腺施万细胞瘤。我们报告一例41岁患者偶然发现的肾上腺肿块，该患者有非典型腹痛。生物学评估无异常，影像学检查未显示典型腺瘤的严格影像学标准。遂决定对肾上腺偶发瘤进行手术切除。切除标本的组织病理学检查和免疫组化染色显示为良性施万细胞瘤。
