蛛网膜下腔良性扩大（BESS）是婴儿大头畸形的原因之一。它是一种自限性疾病，不需要任何积极的药物或手术治疗。我们报告一例4个月大的婴儿，由于婴儿的头围从3个月大的第50百分位数迅速增加到4个月大的第95百分位数以上，因此被转诊进行脑部磁共振成像（MRI）。MRI显示前蛛网膜下腔扩大，所有脑室轻度突出。由于孩子的神经发育正常，怀疑有BESS的可能性。在18个月大时进行的随访MRI显示蛛网膜下腔的大小减小，脑室大小正常。
Benign enlargement of sub-arachnoid spaces (BESS) is one of the causes of macrocephaly in infants. It is a self-limiting condition and does not require any active medical or surgical treatment. We report a case of an infant aged 4 months who was referred for magnetic resonance imaging (MRI) of the brain as the head circumference of the infant had increased rapidly from the 50th percentile in the 3rd month to more than the 95th percentile in the 4th month of age. MRI revealed enlarged anterior sub-arachnoid spaces and mild prominence of all the ventricles. A possibility of BESS was suspected since the child was neurodevelopmentally normal. A follow-up MRI done at the age of 18 months showed a reduction in the size of the sub-arachnoid spaces with normal sized ventricles.
