The presence of intracranial foreign body granulomas is an unusual condition. They can be caused by foreign substances which are either inadvertently or deliberately left in the surgical field. Some foreign materials (textilomas, gossypibomas, gauzomas, muslinomas) along with the resulting foreign body reaction, in the surrounding tissue, can cause infection or abscess formation in an early stage whereas others remain clinically silent for many years.
We present the case of a foreign body granuloma (textiloma) caused by a gauze which had been placed, during a corrective craniotomy, in a patient with Apert syndrome at the age of five. At presentation the clinical and radiological findings were suggestive of an infection.
Surgical exploration of the region demonstrated the presence of gauze, in a frontal bone defect, surrounded by large masses of reactive granular tissue which were extended to the underlying dura mater. The symptoms resolved completely after the foreign body's retrieval.
Foreign body granulomas, although rare, must always be taken under consideration in the differential diagnosis of craniofacial masses or procedures; especially in cases where a previous craniofacial operation has taken place.
颅内异物性肉芽肿较为少见,通常由手术野中无意或故意遗留的异物引起。一些异物(纺织物肉芽肿、棉絮肉芽肿、纱布肉芽肿、麻布肉芽肿)及其周围组织的异物反应可导致早期感染或脓肿形成,而另一些则在数年内保持临床无症状。
我们报告了一例由纱布引起的异物性肉芽肿(纺织物肉芽肿),该患者为五岁的 Apert 综合征患者,在接受矫正性开颅术时纱布被放置在颅内。就诊时,临床和影像学检查结果提示感染。
对该区域进行手术探查显示,在额骨缺损处有纱布,周围有大量反应性颗粒状组织,延伸至下方硬脑膜。取出异物后,症状完全缓解。
异物性肉芽肿虽然罕见,但在颅面肿块或手术的鉴别诊断中,尤其是在先前有颅面手术的情况下,必须始终考虑到这一诊断。
