Pontine glioma and cerebellopontine angle epidermoid tumour occurring as collision tumours.
A 36-year-old male was admitted with a 10-year history of gradually progressive left ear hearing loss, diplopia and right hemiparesis. Magnetic resonance imaging showed a left lateral pontine enhancing tumour and an additional cerebellopontine angle epidermoid tumour in close proximity forming a collision tumour. On exploration, the epidermoid tumour and the intraaxial pontine glioma were completely resected. The literature on collision tumours is reviewed.
