Background:
Choroid plexus papillomas (CPPs) are infrequently encountered brain tumors with the majority originating in the ventricular system. Rarely, CPP occurs outside of the ventricles.
Case description:
We report the case of a recurrent CPP that initially originated within the fourth ventricle, though years later it recurred in the left middle cerebellar peduncle.
Conclusion:
Patients with cerebellar plexus papilloma need long-term follow-up comprising regular magnetic resonance imagings since, in patients with a history of CPP, any new mild symptomatology, even years after the initial presentation, may be an early sign of tumor recurrence.
