Bacteremia [R78.81], Reason for Study: ^Reason: AMS Significant motion artifacts degraded exam quality.T2 high signal intensity lesions within the left sigmoid sinus and jugular bulb suggest unchanged persistent thrombosis without evidence of venous congestive encephalopathy.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no definitive mass, mass effect, edema, midline shift, intra or extra-axial fluid collection.There is no evidence of acute ischemic lesion.The midline structures and cranial-cervical junction are normal. There is right maxillary sinus retention cyst.Bilateral mastoid air cells are opacified, unchanged.
Limited exam.No evidence of acute ischemic stroke.Persistent left sigmoid and jugular bulb thrombosis is suggested.Ventricular system appears to be normal.Comment: If clinically indicated, considering prior MR scan was also poor quality due to patient's motion artifacts, post enhanced scan with either deep sedation or general anesthesia should be considered for more precise MR evaluation.
