Arachnoid cysts of the paranasal sinus are rare. They have not been described yet in the sphenoid sinus.
Microscopic-endoscopic endonasal surgery of the sphenoid sinus was performed on a 34-year-old female with a history of chronic headaches and a suspected mucocele of the sphenoid sinus in computed tomography (CT) and magnetic resonance imaging (MRI) studies. An extended arachnoid cyst was found in the enlarged sphenoid sinus, which was obliterated with collagen, fibrin glue, and abdominal fat.
There were no complications after the operation, and 12 months later the patient is still free of symptoms.
Arachnoidal cysts present in CT and MRI as fluid dense lesions that can imitate a mucocele.
鼻窦蛛网膜囊肿罕见。蝶窦蛛网膜囊肿尚未见报道。
对一名34岁女性进行了蝶窦显微镜下鼻内镜手术，该患者有慢性头痛病史，计算机断层扫描（CT）和磁共振成像（MRI）检查怀疑为蝶窦黏液囊肿。在扩大的蝶窦中发现一个巨大的蛛网膜囊肿，用胶原、纤维蛋白胶和腹部脂肪将其填塞。
术后无并发症，12个月后患者仍无症状。
蛛网膜囊肿在CT和MRI上表现为液性致密病变，可类似黏液囊肿。
