An 85-year-old man underwent emergency right trepanation and drainage for a symptomatic chronic subdural hematoma. Pseudohypoxic brain swelling (PHBS) was suspected because magnetic resonance imaging revealed diffuse brain swelling. Although cerebrospinal fluid (CSF) leakage was not obvious during or after surgery, most of the reported PHBS cases have leaked CSF during craniotomy or spine surgery. PHBS has not been previously reported in patients without obvious CSF leakage or after unilateral burr hole drainage. Herein, we report an extremely rare case with a literature review investigating its pathogenesis and clinical features.
一名85岁男性因有症状的慢性硬膜下血肿接受了急诊右侧颅骨钻孔引流术。磁共振成像显示弥漫性脑肿胀，怀疑为假性缺氧性脑肿胀（PHBS）。尽管手术期间或术后脑脊液（CSF）漏并不明显，但大多数报道的PHBS病例在开颅手术或脊柱手术期间有脑脊液漏。此前尚未有在无明显脑脊液漏的患者或单侧钻孔引流术后发生PHBS的报道。在此，我们报告一例极其罕见的病例，并进行文献复习以探讨其发病机制和临床特征。
