We report an extremely rare case of congenital cholesteatoma of the infratemporal fossa.
The clinical, radiological and intra-operative findings of the patient are presented.
A five-year-old girl presented to our hospital with symptoms in the left ear consistent with middle-ear effusion. A congenital cholesteatoma was not suspected until an enlarging mass in the anteroinferior quadrant of the tympanic membrane was observed. Radiological studies revealed that the mass was located largely in the infratemporal fossa, with limited extension into the tympanic cavity. The patient underwent surgical treatment, which confirmed the clinical and radiological findings.
This patient's clinical, radiological and intra-operative findings strongly suggested the infratemporal fossa as the site of origin of her congenital cholesteatoma.
我们报告一例极为罕见的颞下窝先天性胆脂瘤病例。
介绍该患者的临床、影像学及术中发现。
一名5岁女童因左耳出现与中耳积液相符的症状前来我院就诊。直到观察到鼓膜前下象限有一逐渐增大的肿物，才怀疑是先天性胆脂瘤。影像学研究显示，肿物主要位于颞下窝，仅有限地延伸至鼓室。患者接受了手术治疗，证实了临床和影像学检查结果。
该患者的临床、影像学及术中表现强烈提示颞下窝是其先天性胆脂瘤的起源部位。
