====== Asterional dermoid cyst ======

[[Asterion]] is an uncommon site for [[lesion]]s, especially [[dermoid cyst]]s. 

Guarnera et al. from the [[S. Andrea Hospital]] reported a [[case series]] of three [[asterion]]al [[intracranial dermoid cyst]]s, which, have never been described before. Patients presented with non-specific symptoms and underwent surgical [[excision]] of the lesions. It is crucial to correctly diagnose [[intracranial]] [[mass]]es and to identify their relationships with surrounding anatomical structures, especially if the location is unusual as the asterion, to plan surgery. The challenge of this [[tumor]] location is to preserve the venous drainage system during surgical procedures, because of the contiguity between the asterion and the [[transverse]]-[[sigmoid]] junction. Rupturing or damaging of the venous drainage system have been proven to be catastrophic because they lengthen surgical time and present dire consequences for patients. In conclusion, it is crucial to familiarize with atypical dermoid presentation to ensure proper diagnoses and to perform adequate imaging for optimal surgical [[planning]]
