Abstract

A 3-year-old boy presented with acute headache, vomiting and right focal clonic seizures without history of fever, joint pain or altered sensorium. Neuroimaging showed multifocal contrast enhancing lesions with significant perilesional edema. CECT chest and abdomen showed multiple variable sized nodules in the lungs and hypodense lesion in liver with mesenteric lymphadenopathy. There was persistent eosinophilia with maximum upto 35 %. Liver biopsy and brain biopsy revealed Cladophialophora bantiana. He was treated with IV liposomal amphotericin and voriconazole for 6 weeks with repeat neuroimaging showing more than 50 % resolution of the intracranial lesions. He was transitioned to oral combination of flucytosine and voriconazole. At 14 months follow-up, he remained symptom free with complete radiological resolution of the lesions and no eosinophilia. High suspicion, an aggressive approach in obtaining microbiological diagnosis and timely combination antifungal therapy may give satisfactory outcome without surgery.

摘要

一名3岁男孩出现急性头痛、呕吐和右侧局灶性阵挛性癫痫发作,无发热、关节疼痛或意识改变病史。神经影像学检查显示多灶性强化病变,病灶周围有明显水肿。胸部和腹部CT增强扫描显示肺部有多个大小不一的结节,肝脏有低密度病变,伴有肠系膜淋巴结肿大。嗜酸性粒细胞持续增多,最高可达35%。肝脏活检和脑活检显示为班替枝孢霉。给予静脉注射脂质体两性霉素和伏立康唑治疗6周,重复神经影像学检查显示颅内病变消退超过50%。随后改为口服氟胞嘧啶和伏立康唑联合治疗。在14个月的随访中,他无症状,病变在影像学上完全消退,且无嗜酸性粒细胞增多。高度怀疑时,积极获取微生物学诊断并及时进行联合抗真菌治疗,无需手术即可取得满意疗效。
