Rosai-Dorfman disease (RDD) was first described in 1969 as an idiopathic histiocytic proliferative disorder. It commonly presents as a massive and painless adenopathy. Until 1990, extranodal involvement of the central nervous system (CNS) was rare and reported in less than 5% of the total number of patients with extranodal RDD. Complete removal of CNS RDD has been achieved in many cases.
We report a case of an isolated intracranial RDD in a 53-year-old man. The patient had an episode of generalized seizures. Imaging studies of the brain were compatible with a meningioma en plaque. The mass was exposed by a right frontotemporal craniotomy. The tumor was adhered tightly to the adjacent cerebral cortex and was permeated by pial arteries of the brain surface. The sacrificing of these arteries was inevitable in order to achieve the total removal of the tumor. The patient had incomplete left hemiparesis after the surgery. Brain computed tomography (CT) imaging revealed a postoperative hemorrhage and a low-density lesion in the right frontal lobe. The patient was postoperatively diagnosed with isolated central nervous system RDD.
Although the complete removal of dural-based lesions without any neurological deficits has been performed in many cases, the treatment of cases with high risks, such as the present case, indicates conservative excisions and adjuvant radiotherapy with or without chemotherapy.
罗萨伊-多夫曼病(RDD)于1969年首次被描述为一种特发性组织细胞增生性疾病。它通常表现为巨大且无痛的淋巴结病。直到1990年,中枢神经系统(CNS)的结外受累情况罕见,在结外RDD患者总数中报告的比例不到5%。许多病例已实现CNS RDD的完全切除。
我们报告一例53岁男性的孤立性颅内RDD病例。患者有一次全身性癫痫发作。脑部影像学检查结果与平板状脑膜瘤相符。通过右额颞开颅术暴露肿块。肿瘤与相邻的大脑皮层紧密粘连,并被脑表面的软脑膜动脉穿透。为了实现肿瘤的完全切除,不可避免地要牺牲这些动脉。术后患者出现不完全性左侧偏瘫。脑部计算机断层扫描(CT)成像显示术后出血以及右额叶的低密度病变。该患者术后被诊断为孤立性中枢神经系统RDD。
尽管许多病例已在不出现任何神经功能缺损的情况下实现了硬膜下病变的完全切除,但对于像本病例这样的高风险病例的治疗,表明需要进行保守切除以及联合或不联合化疗的辅助放疗。
