Insular operculum disconnection and herniation into the parapharyngeal space due to a fetal Galassi Type III arachnoid cyst: a case report. | LitMetric
- Arachnoid cysts (ACs) are commonly found in the brain and usually don’t cause symptoms, but they can occasionally lead to significant brain issues.
- This study presents a case of an 8-day-old girl with a mass related to an insular operculum, found to be herniated due to a Galassi Type III AC, affecting her left hearing ability.
- The report emphasizes that early fetal ACs can protrude through unossified parts of the skull, potentially impacting brain tissue development.
Article Abstract
Arachnoid cysts (ACs) are frequently encountered as incidental findings in the brain, with most cases being asymptomatic and not requiring intervention. However, severe brain malformations caused by ACs are rare. In this study, we describe the case of an 8-day-old female infant with a left mandibular mass that was diagnosed as an insular operculum, which has become disconnected and herniated into the parapharyngeal space through an incompletely ossified greater wing of the sphenoid, caused by a fetal Galassi Type III AC. The newborn also exhibited left hearing impairment, which did not improve at the 6-month follow-up after the cyst peritoneal shunt. This report highlights that ACs that manifest during the early fetal period may protrude from the cranial cavity through an unossified skull, potentially affecting the development of brain tissues.
