CT: extra-axial expansive lesion isodense, located in the left bulbocerebelar cistern with moderate enhancement by means of intravenous iodinated contrast, situated adjacent to the same jugular foramen.
CT Angiography: The extra-axial mass located adjacent to the jugular foramen, but no evidence of bone erosion or vascular invasion signals and demonstrates discreet contrast enhancement.
Fusion of CT and MRI images T1C + shows mass lesion located in the left cerebellar cistern bulb, adjacent to the jugular foramen, with emphasis on the means of contrast evidenced in sequence T1 C + in MRI.
