Central nervous system (CNS) aspergillosis has the characteristics of multifocality, polymorphism, and coexistence of pathological types, and missed diagnosis and misdiagnosis frequently occur at the initial stage. The thesis reports a rare case of infant infection of CNS aspergillosis with the first-episode of intracranial hemorrhage.
An 11-month-old female infant suffered convulsion and coma two days after the onset of fever and emesis. Its cranial computed tomography (CT) displayed subdural hemorrhage in the left tentorium cerebelli and tests indicated normal cerebrospinal fluid (CSF). Three days after being hospitalized, the infant had difficulty breathing and its CT presents consolidation in the right lung. However, treatment with ceftriaxone (ivgtt) had no effect on the baby.
The patient's bronchoalveolar lavage fluid (BALF) was cultured into Aspergillus spp, its galactomannan (GM) antigen in CSF counted 3.0, higher than that in BALF which counted 2.6, and cranial magnetic resonance imaging (MRI) revealed multiple ring reinforced tubercles in sulci. Hence it was clinically diagnosed with CNS aspergillosis.
Voriconazole for intravenous injection. After the intravenous injection, its trough concentration was 4.2 μg/mL, and it was within the recommended range.
After one week's treatment with voriconazole, the infant's consciousness was improved. Four weeks later, with normothermia and clear consciousness, the patient was discharged. With oral administration of voriconazole up to 16 weeks, its physical state suggests no relapse and cranial MRI indicated disappearance of nodules in sulci.
CNS aspergillosis with first-episode of intracranial hemorrhage probably leads to misdiagnosis and GM test combined with cranial MRI can augment its accuracy in the early diagnosis.
中枢神经系统(CNS)曲霉菌病具有多灶性、多态性及病理类型并存的特点,在疾病初期常发生漏诊和误诊。本文报道1例罕见的以颅内出血为首发表现的婴幼儿CNS曲霉菌感染病例。
一名11个月大的女婴在发热、呕吐2天后出现惊厥和昏迷。其头颅计算机断层扫描(CT)显示左侧小脑幕下硬膜下出血,脑脊液(CSF)检查正常。住院3天后,患儿出现呼吸困难,CT显示右肺实变。然而,头孢曲松(静脉滴注)治疗对患儿无效。
患者支气管肺泡灌洗液(BALF)培养出曲霉菌属,脑脊液中半乳甘露聚糖(GM)抗原计数为3.0,高于BALF中的计数2.6,头颅磁共振成像(MRI)显示脑沟内多个环形强化结节。因此临床诊断为CNS曲霉菌病。
静脉注射伏立康唑。静脉注射后,其谷浓度为4.2μg/mL,在推荐范围内。
伏立康唑治疗1周后,患儿意识改善。4周后,患儿体温正常,意识清醒,出院。口服伏立康唑达16周,患儿身体状况无复发迹象,头颅MRI显示脑沟内结节消失。
以颅内出血为首发表现的CNS曲霉菌病可能导致误诊,GM检测联合头颅MRI可提高其早期诊断的准确性。
