Reason: please assess for vascular disease and possible prior infarction History: transient loss of vision on R eye There is a small focus of signal loss identified only on susceptibility weighted images along the anterior aspect of the right cingulate gyrus associated with a developmental venous anomaly draining into the anterior septal vein.The CSF spaces are appropriate for the patient's stated age with no midline shift. 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. A 7mm well circumscribed focus of T2 and FLAIR signal hyperintensity and intermediate signal on T1 and without diffusion restriction between the right mastoid and the jugular vein is present adjacent to the skull base. It could represent an arachnoid granulation but is non-specific.
1.A small vascular lesion along the right cingulate gyrus is present. Differential considerations include vascular malformation including cerebral cavernous malformation or a small arteriovenous malformation. High resolution imaging and/or an angiographic study may be helpful.2.An email was sent to Dr Cotts regarding the above finding.
