29-year-old male with a history of cavernous malformation here for yearly surveillance. No specific symptomatology is provided. Redemonstrated is 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 and again measures 11 x 11 mm in axial dimensions. There is no perilesional edema.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.Worsening mucosal thickening with air fluid levels are present within bilateral maxillary and sphenoid sinuses. Mucosal thickening within the ethmoid air cells is stable. The visualized mastoid air cells are clear. Redemonstrated is some medial protrusion of orbital contents into the left ethmoid air cells suggesting old medial blowout fracture in the left orbit.
1.The patient's cavernous malformation located in the left parietal lobe is stable compared to the prior exam.2.Worsening mucosal thickening with air fluid levels are present within bilateral maxillary and sphenoid sinuses.
