作者使用扇形超声经小儿未闭前囱检查５０例颅内占位性病变，检出颅内血肿４０例，脑脓肿９例，囊肿１例，其中１３例超声检查后经ＣＴ证实，１例脑脓肿病人临床穿刺获脓液，１例囊肿病人反复超声检查无改变。３５例超声明确诊断后给予相应治疗，病情好转，超声复查肿块缩小，回声减弱。本组首次超声检查有４９例合并不同程度脑室扩张，治疗后１～３月复查，１８例脑室大小恢复正常。由此可见，早期颅内占位性病变合并脑室轻度扩张的大部份病人只是暂时性脑室扩张，并不发展成脑积水。
The authors used scalloped ultrasound to diagnose 50 cases of intracranial space-occupying lesions in the anterior peduncle of children. Forty intracranial hematomas, 9 brain abscesses and 1 cyst were detected. Among them, 13 were confirmed by CT after ultrasound examination and 1 Abscess patients with clinical puncture pus, 1 case of cyst patients repeated ultrasound examination without change. 35 cases of definite diagnosis of ultrasound given the appropriate treatment, the condition improved, ultrasound recheck the tumor shrinks, echo weakened. The group for the first time in 49 cases of ultrasound combined with varying degrees of ventricular dilatation, 1 to 3 months after treatment review, 18 cases of ventricular size returned to normal. Thus, most of the patients with early intracranial space-occupying lesions complicated with mild ventricular dilatation are only temporary ventricular dilatation and do not develop into hydrocephalus.
