A retrospective study was performed evaluating the volume and T2/T1 signal intensity of orbital fat in five children diagnosed with severe global brain swelling and confirmed cessation of cerebral perfusion. Imaging showed a volume increase (five of five) and a heterogeneous T2-hypointensity of orbital fat (four of five). This preliminary study suggests that swelling and T2-hypointensity of orbital fat may be a marker of global brain swelling and/or increased intracranial pressure.
一项回顾性研究评估了五名被诊断为严重全脑肿胀且确认脑灌注停止的儿童的眶脂体积和 T2/T1 信号强度。影像学显示眶脂体积增加（五例均增加）且 T2 低信号不均（四例均不均）。这项初步研究表明，眶脂肿胀和 T2 低信号可能是全脑肿胀和/或颅内压增高的标志。
