Left cerebellopontine angle (CPA) metastasis from a lung primary. T1W gadolinium-enhanced axial (A) and T2W (B) axial MRI. It is sometimes difficult to distinguish intra-axial from extra-axial CPA lesions when the CPA is obliterated. This inhomogenously enhancing left CPA mass is a metastasis. The lack of cerebellar oedema suggests an extra-axial location.
