28-year-old male with a history of cavernous malformation here for yearly surveillance. No specific symptomatology is provided. There is redemonstration of a focus of susceptibility effect associated with a centrally higher T1 signal and a popcorn-like appearance located within the left parietal lobe. This has not changed in size when compared to the prior exam. It measures 11 x 11 mm in axial dimensions.Normal vascular flow voids are present in the distal internal carotid arteries, distal left vertebral artery and the proximal anterior middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus. Findings suggest a hypoplastic right vertebral artery.The visualized paranasal sinuses demonstrate mucosal thickening. The visualized mastoid air cells are clear. There is some medial protrusion of orbital contents into the left ethmoid air cells suggesting old medial blowout fracture in the left orbit. This finding was also present on the prior exam and is unchanged.
1.The patient's cavernous malformation located in the left parietal lobe is stable compared to the prior exam.
