Transcortical approach to a huge pineal mature teratoma.
Intracranial teratomas are rare germ cell neoplasms occurring more often during childhood. We report the case of a huge mature teratoma of the pineal region in a 10-year-old patient that was not correctly diagnosed preoperatively by stereotactic biopsy. The tumor was revealed by intracranial hypertension and a Parinaud syndrome. The tumor markers were within normal levels in the serum. A left transcortical parietal approach was used to completely resect the tumor. No adjuvant treatment was given. A complete neurological recovery was observed after the surgical procedure. Follow-up at 2 years did not show any recurrence. Pineal mature teratomas have a good prognosis, in contrast to their immature or mixed counterparts. A rigorous histological examination of the tumor samples is mandatory, in order to not omit a mixed contingent within the tumor. The treatment is exclusively surgical.
