RT Journal Article SR Electronic T1 Spontaneous Sphenoid Sinus Mucocele Revealed by Meningitis and Brain Abscess in a 12-Year-Old Child JF American Journal of Neuroradiology JO Am. J. Neuroradiol.

This report describes an unusual case revealed by bacterial meningitis and cerebral abscess in a 12-year-old child. CT and MR imaging allowed precise extension to the skull base in preoperative management and follow-up investigations. Endoscopic transnasal marsupialisation of the mucocele and antibiotic therapy led to complete remission. There was no evidence of recurrence after 6 months, which suggests that sphenoid mucoceles, regardless of size and complications, can be treated by endoscopic sinus surgery.
