Aspiration of inflorescence or grass heads (seed head of grasses) often presents with atypical signs and symptoms because grass heads have a tendency to rapidly migrate to the periphery of the lung. If this is not recognized, it can lead to delay in diagnosis and serious complications. Removal with rigid bronchoscopy maybe difficult, and surgery is often needed. We report a case of a seven-month-old child who had a delayed diagnosis of grass head aspiration and subsequently presented with a life threatening tension pneumothorax. This case highlights the importance of obtaining a detailed history in cases of foreign body aspiration and the need to include it in the differential diagnosis of unexplained respiratory symptoms, especially those of sudden onset in children.
吸入花序或草穗（禾本科植物的种子头）通常会出现非典型的体征和症状，因为草穗容易迅速迁移至肺周边。如果未识别出这一点，可能会导致诊断延误及严重并发症。用硬质支气管镜取出可能困难，通常需要手术。我们报告一例7个月大儿童，其草穗吸入诊断延迟，随后出现危及生命的张力性气胸。该病例强调了在异物吸入病例中获取详细病史的重要性，以及在不明原因呼吸道症状（尤其是儿童突发症状）的鉴别诊断中纳入该病史的必要性。
