Torticollis as a Rare Presentation of Cerebellopontine Angle Choroid Plexus Papilloma in Children

Background and Importance:

 The rare intracranial neoplasms are Choroid Plexus Papillomas (CPPs), especially in the cerebellopontine angle. The main location of Choroid Plexus Papillomas in adults and children are 4th ventricle and lateral ventricles, respectively.

We report on a little girl with a cerebellopontine angle CPP who presented with symptoms of torticollis. Assessment of Magnetic Resonance Imaging showed a mass in the right cerebellopontine angle, just next to the brain stem. The tumor was completely resected using the right retrosigmoid approach method.

A pathological examination determines a typical CPP that this being should be considered an extremely rare cause of a lesion in the posterior fossa.
