We report a rare case of idiopathic adrenal hematoma. Including our case, 13 such cases have been described in Japan. A 63-year-old [correction of 65] woman was admitted to our hospital for further examination of a right adrenal mass on ultrasonography. Laboratory tests including hormonal assay were within the normal ranges. Computed tomography showed a tumor with calcification measuring 3.0 x 2.0 cm in the right adrenal gland. Magnetic resonance imaging (MRI) revealed a mass with heterogeneous low to iso signal intensity on T1-weighted images and high signal intensity on T2-weighted images. A peripheral rim of the mass was slightly enhanced on dynamic MRI. The patient underwent laparoscopic adrenalectomy. Histopathological examination revealed an old hematoma without neoplastic cells or vascular lesions and these findings were evidence of idiopathic adrenal hematoma.
我们报告一例罕见的特发性肾上腺血肿病例。包括我们的病例在内，日本已报道过13例此类病例。一名63岁[应为65岁]女性因超声检查发现右肾上腺肿块而入院进一步检查。包括激素检测在内的实验室检查结果均在正常范围内。计算机断层扫描显示右肾上腺有一个大小为3.0×2.0 cm的钙化肿瘤。磁共振成像（MRI）显示，该肿块在T1加权图像上呈低信号至等信号强度不均质，在T2加权图像上呈高信号强度。在动态MRI上，肿块周边略有强化。患者接受了腹腔镜肾上腺切除术。组织病理学检查显示为陈旧性血肿，无肿瘤细胞或血管病变，这些发现为特发性肾上腺血肿的证据。
