48 years Female (DOB:2/22/1968)Reason: change in right frontal lesion, probable cavernoma? History: headachesPROVIDER/ATTENDING NAME: JAMES R. BRORSON JAMES R. BRORSON There is a ringlike focus of susceptibility effect present also identified on the T2 and T1 images measuring approximately 5 mm in diameter. It is associated with susceptibility effect. There is also associated with a developmental venous anomaly. This is stable compared to prior exam.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
Findings are compatible with a small cortically based cerebral cavernous malformation associated with a developmental venous anomaly involving the right frontal lobe anteriorly and adjacent to the midline. The patient has a known history of thyroid cancer. Although this remains in the differential diagnosis, the association with developmental venous anomaly supports cerebral cavernous malformation.
