Extracerebral choroid plexus papilloma in a newborn: a rare presentation.

Choroid plexus papillomas (CPPs) are extremely rare lesions that originate in the central nervous system. Still rarely, these can occur in heterotopic locations. We report a case of aneonate who presented at fourth week of life with a small swelling in the left side of the oropharynx. There were no other symptoms. MRI scan revealed a cystic lesion with the possibility of lymphatic malformation or teratoma. Swelling which was gradually increasing in size was electively excised. Histopathological examination revealed it to be an extracerebral CPP. Postoperative period was uneventful, and baby had no further complications. CPP is a rare lesion and, almost always, cannot be anticipated before surgery. Imaging only helps in surgical planning. Complete excision is curative.
