ABSTRACT
OBJECTIVE:
To determine the clinical significance of arachnoid cysts.METHODS:
The scans of 6978 patients undergoing magnetic resonance imaging of the internal acoustic meatus for unilateral cochleovestibular symptoms were retrospectively reviewed. We identified the scans with arachnoid cysts, and assessed the statistical associations between the laterality, location and size of the arachnoid cyst, the laterality of symptoms, the patients' age and gender.RESULTS:
In a total of 37 arachnoid cysts identified in 36 patients (0.5 per cent), no associations were identified between the laterality of symptoms and the laterality of the arachnoid cyst, regardless of its size or location. There were no significant associations between the location of the arachnoid cyst and the age (p = 0.99) or gender of the patient (p = 0.13), or size (p = 0.656) or side of the cyst (p = 0.61). None of the cysts with repeat imaging scans (17 cysts) demonstrated growth.CONCLUSION:
Our results suggest that most, if not all, arachnoid cysts are of no clinical significance. Given their indolent behaviour, even serial imaging is not essential.Palabras clave
