Connatal Cyst in a 50-Year-Old Patient

Abstract

In this letter to the editor, we would like to report a case of incidental connatal cyst in a 50-year-old male patient. The patient was on migraine medications; however, he had recurrent episodes of headaches with nausea and was asked to perform a magnetic resonance imaging (MRI) by a treating physician.Thereisnopasthistoryofseizures,paresisorplegia, sensorineural de fi cits, cranial nerve involvement, urinary incontinence, etc. in the patient. The patient was born of a normal delivery at term, with no history of neonatal hospitalization, prolonged jaundice, and respiratory distress. Neurological examination was normal. On MRI, T2-weighted (T2W) coronal images showed bilateral hyperintense cysts located superolaterally to frontal horns ( ► Fig. 1A and B ). Similarly axialT2Wimagesshowedthehyperintensecystanteriortothe frontal horns ( ► Fig. 1C ). On fl uid-attenuated inversion recovery coronal images and T1W, they appeared hypointense ( ► Fig. 2A and B ) without any evidence of associated in fl am-mation and periventricular gliosis. Given the location and no signi fi cantneonatalhistoryinthepatients,the fi ndingsonMRI are consistent with frontal horn cyst aka coarctation of lateral ventricles or connatal cysts. Connatal
