Abstract

Schwannomas are rare tumors in the retroperitoneal location. They can pose a diagnostic dilemma when presenting as an adrenal mass lesion due to their imaging characteristics. We report two cases of juxta-adrenal schwannomas presenting as symptomatic adrenal mass lesions. In both the cases, the clinical examination and functional evaluation was unremarkable and the radiological examination revealed a mixed intense adrenal mass lesion in one case with predominantly hyperintense areas and a very hyperintense lesion in another, in T2-weighted images, mimicking a adrenocortical malignancy and a pheochromocytoma respectively. Both cases were treated by surgical excision. Histopathological examination established the correct diagnosis of schwannoma, which was confirmed by immunohistochemical staining. Juxta-adrenal schwannoma is rare tumors of the retroperitoneum, which should also be borne in mind whenever encountering large nonsecreting adrenal tumors. We report a unique imaging characteristic, which helps in preoperative identification these rare lesions.

摘要

神经鞘瘤是腹膜后少见的肿瘤。当表现为肾上腺肿块病变时，因其影像学特征可能会造成诊断难题。我们报告两例表现为有症状肾上腺肿块病变的肾上腺旁神经鞘瘤。两例患者临床检查和功能评估均无异常，放射学检查显示，在T2加权图像中，一例为混合强化的肾上腺肿块病变，主要为高强化区域，另一例为极高强化病变，分别酷似肾上腺皮质恶性肿瘤和嗜铬细胞瘤。两例均行手术切除治疗。组织病理学检查确诊为神经鞘瘤，免疫组化染色予以证实。肾上腺旁神经鞘瘤是腹膜后罕见肿瘤，在遇到大型无分泌功能的肾上腺肿瘤时也应予以考虑。我们报告了一种独特的影像学特征，有助于术前识别这些罕见病变。
