Abstract
Summary:Arachnoid cysts are benign intracranial lesions that are typically diagnosed incidentally. They are divided into two types: congenital and acquired. Acquired arachnoid cysts are rare and usually arise after trauma, infection, or haemorrhage. In this report, a rare case of an iatrogenic multiloculated arachnoid cyst as an unusual complication of a skull base defect is presented. It extended extracranially into the sphenoid sinus, the ethmoid, the infratemporal fossa, the nasopharynx and the nasal cavity, as well as into the pterygomaxillary and retromaxillary space, appearing with a distinct clinical picture. We discuss the differential diagnosis and the potential causes of the lesion and provide a brief review of the literature.
