Cranial ultrasonography was performed on 61 infants with acute bacterial meningitis (ABM). Thirty nine, infants (64%) had acute meningitis with no clinical evidence of complications (Group-I) and 22 infants (36%) had clinical evidence of complications of ABM (Group-II). Cranial ultrasound was normal in 20 infants (32.8%). The spectrum of sonographic abnormalities included echogenic sulci (60.6%), sulcal separation (49.8%), abnormal parenchymal echoes (42.6%), ventriculomegaly (34.4%), ventriculitis (19.7%), abscess (3.3%), subdural empyema (1.63%) and hemorrhagic infarct (1.63%). Various abnormal findings were seen in all 22 patients of Group II (100%) and in only 19 out of 39 patients in Group I (31.9%). Cranial sonography was comparable to CT scan done in 10 cases of Group II. Our study suggests that ultrasound is a quick, reliable and effective diagnostic tool in diagnosis and management of infants with or without evidence of complications.
对61例急性细菌性脑膜炎（ABM）婴儿进行了头颅超声检查。39例婴儿（64%）患有急性脑膜炎且无并发症的临床证据（第一组），22例婴儿（36%）有ABM并发症的临床证据（第二组）。20例婴儿（32.8%）的头颅超声检查结果正常。超声异常表现包括脑沟回声增强（60.6%）、脑沟分离（49.8%）、实质回声异常（42.6%）、脑室扩大（34.4%）、脑室炎（19.7%）、脓肿（3.3%）、硬膜下积脓（1.63%）和出血性梗死（1.63%）。第二组的所有22例患者（100%）以及第一组39例患者中的19例（31.9%）均出现了各种异常表现。对第二组中的10例患者进行的头颅超声检查结果与CT扫描结果相当。我们的研究表明，超声是诊断和管理有无并发症证据的婴儿的一种快速、可靠且有效的诊断工具。
