Clinical question: Surveillance scan of right frontal cerebrovascular anomaly, CCM protocol on 3T. signs and symptoms: New onset of seizure Pre-and post-enhanced brain MRI:Negative diffusion weighted series.Examination redemonstrates a previously known right middle frontal gyrus developmental venous anomaly without evidence of an associated cavernous malformation. There is no evidence of interval change since prior exams.Unremarkable anatomical morphology and signal intensity of brain parenchyma otherwise on all MRI sequences.Unremarkable surgical cortex, cortical sulci, ventricular system and the CSF spaces. Normal visualization of signal void of major intracranial arterial branches.Normal signal intensity of intracranial venous sinuses and with normal pattern of enhancement.Unremarkable calvarium, soft tissues of the scalp, orbits and without abnormal enhancement.There is a small retention cyst in the left maxillary sinus stable since prior study are unremarkable paranasal sinuses otherwise.
1.Pre-and post-enhanced brain MRI demonstrates a right frontal developmental venous anomaly without interval change since prior study. Unremarkable pre-and post enhanced brain MRI otherwise.
