Childhood parotid swelling has a number of differential diagnosis mostly of inflammatory origin. Pneumoparotitis is an uncommon cause of parotid inflammation. It is caused by an excessive increase of intraoral pressure and secondary passage of air into the Stensen or Stenon duct and its glandular branches. Diagnostic clues can usually be obtained by a directed anamnesis. Ultrasonography (US) and computed tomography are essential diagnostic tools for this condition that has a benign course with spontaneous resolution in most cases. We present four cases of pneumoparotitis diagnosed by US in children 5 to 13 years of age. One of the cases occurred after the child chewed gum and made bubbles for a prolonged time-period and the other three after inflating baloons, making bubbles inside a pool and after playing the flute. All cases resolved spontaneously after two days. We suggest to consider pneumoparotitis in the differential diagnosis of parotid swelling in children.
儿童腮腺肿大有多种鉴别诊断，大多源于炎症。气肿性腮腺炎是腮腺炎症的一种罕见病因。它是由口腔内压力过度增加以及空气继发进入斯滕森（Stensen）导管或斯滕诺（Stenon）导管及其腺支所致。通常可通过针对性问诊获取诊断线索。超声检查（US）和计算机断层扫描是诊断此病的重要工具，该病多数情况下呈良性病程且可自发缓解。我们报告4例经超声诊断为气肿性腮腺炎的5至13岁儿童病例。其中1例发生在儿童长时间嚼口香糖吹泡泡之后，另外3例分别发生在吹气球、在泳池内吹泡泡以及吹奏长笛之后。所有病例均在两天后自发缓解。我们建议在儿童腮腺肿大的鉴别诊断中考虑气肿性腮腺炎。
