This study reported a case of an arachnoid cyst of the sphenoid bone causing orbital signs and symptoms in a 58-year-old man with progressive proptosis and nonspecific discomfort in the OS. Orbital MRI showed a 3-cm homogeneous cyst within the left greater wing of the sphenoid bone. To the best of our knowledge, this is the first report of an intradiploic arachnoid cyst in the sphenoid bone with atypical radiological features, causing clinical symptoms, and managed through an eyelid approach, achieving a complete resolution with no complications.

Proper skull base repair is essential in preventing postoperative cerebrospinal fluid (CSF) leak following endonasal endoscopic skull base surgery. Direct suturing of the skull base dura is desirable but difficult. Here, we discuss the effectiveness of endoscopic suturing of skull base dura in cases of skull base lesions with intraoperative CSF leak.

Article Synopsis
  • - The study investigates the prenatal and postnatal features, along with genetic traits, of Lymphedema-Distichiasis syndrome (LDS) in two Chinese families with FOXC2 gene mutations.
  • - Genetic analysis revealed pathogenic variants in the FOXC2 gene for both families, with literature review yielding a total of 117 identified LDS patients, including prenatal signs in 13 cases and postnatal manifestations in 110.
  • - Key prenatal symptoms of LDS include increased nuchal translucency and fetal edema, while postnatal symptoms commonly feature distichiasis and lymphedema, with only a few cases exhibiting signs before and after birth.
