Diagnosis: Other convulsions. Altered mental statusClinical question: r/o mass lesion or ischemiaSigns and Symptoms: seizure MRI of the brainThe CSF spaces are appropriate for the patient's stated age with no midline shift. No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.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 demonstrate opacification of the right frontal sinus. The visualized portions of the mastoid air cells demonstrate partial opacification of the left mastoid air cells and to a lesser degree right mastoid air cells. The visualized portions of the orbits are intact.Incidental note is made of partial empty sella.MRV brain:The dural venous sinuses are patent. The right transverse sinus, sigmoid sinus and jugular vein are asymmetrically smaller than their left sided counterparts. The prior CT of the head demonstrates a small right sigmoid sinus groove. Straight sinus, internal cerebral veins and basal veins are identified and appear patent. The basal veins are relatively small.
1.There is no evidence for dural sinus thrombosis.2.There is no evidence for intracranial mass lesion or hemorrhage.3.There is no evidence for acute ischemic cerebral infarction.
