A 2-year-old female patient presented after experiencing a generalized tonic-clonic seizure accompanied by fever, followed by a loss of consciousness. She underwent an urgent right frontal external ventricular drain placement. Intraoperative cerebrospinal fluid analysis was negative for infectious patterns. MRI showed a predominantly cystic lesion in the midline posterior fossa, with a compressive mass effect. Subsequently, she underwent a suboccipital craniotomy for microscopic resection of a posterior cranial fossa lesion. Histopathology reported keratin flakes with severe active inflammation, and foreign body type giant cell reaction in scalp excision with free hair shafts through the inflammatory focus, consistent with pilonidal sinus. The patient was then discharged home in good health.
一名2岁女性患者在经历全身性强直阵挛性癫痫发作并伴有发热，随后意识丧失后前来就诊。她接受了紧急的右额叶外侧脑室引流管置入术。术中脑脊液分析未发现感染性特征。磁共振成像（MRI）显示后颅窝中线处主要为囊性病变，伴有占位压迫效应。随后，她接受了枕下开颅手术，以显微切除后颅窝病变。组织病理学报告显示有角质鳞片，伴有严重的活动性炎症，在头皮切除标本中可见穿过炎症灶的游离毛干的异物型巨细胞反应，符合藏毛窦表现。该患者随后健康出院。
