Occurrence of tension pneumoventricle (symptomatic intraventricular air) can result in rapid clinical deterioration in an otherwise stable patient. It is a rare clinical entity, mentioned in relation to cerebrospinal fluid (CSF) diversion procedures, during the late postoperative period. We present a patient with posterior third ventricular tumor who underwent excision by midline suboccipital craniotomy in sitting position. Neurological status of the patient deteriorated rapidly in the immediate postoperative period owing to development of tension pneumoventricle. The condition improved after twist-drill burr-hole evacuation of air under water-seal. Pre-existing gross hydrocephalus, exploration of third ventricle in sitting position, and residual tumor in third ventricle were possibly the factors responsible for this complication.
张力性脑室积气（有症状的脑室内积气）的出现可导致原本病情稳定的患者临床状况迅速恶化。它是一种罕见的临床情况，在术后晚期与脑脊液（CSF）分流手术相关。我们报告一名患有第三脑室后部肿瘤的患者，该患者在坐位下行枕下中线开颅肿瘤切除术。术后即刻患者的神经状况因张力性脑室积气的发生而迅速恶化。在水封下通过钻孔引流积气后病情改善。术前存在的严重脑积水、坐位下对第三脑室的探查以及第三脑室内的残留肿瘤可能是导致该并发症的因素。
