18-year-old male with history of cerebrovascular malformation. Preoperative planning. This study is limited to T1 and T2 sequences secondary to Stealth acquisition protocol.Redemonstrated is an evolving and contracting hematoma adjacent to the right caudate head now measuring 5 x 4 mm on the T2 weighted sequence. There is a surrounding T2 hypointense hemosiderin rim. There is no significant surrounding vasogenic edema. No mass-effect or midline shift. Adjacent to this hematoma, there is a right frontal lobe developmental venous anomaly coursing cranially into a curvilinear vascular malformation within the right superior frontal gyrus measuring proximally 9 x 6 mm, which again demonstrates significant enhancement which would be unusual for a cavernoma. Blooming artifact is again noted on susceptibility. Ventricles and sulci within normal limits. The cisterns are patent. There is no midline shift or mass-effect. There is complete opacification of the right frontal sinus extending into the right anterior ethmoid air cells. Additionally, the right maxillary sinus demonstrates complete opacification and moderate mucosal thickening.
1.Limited Stealth protocol. Redemonstration of presumed cavernoma and superimposed resolving hematoma near the right caudate head as well as associated developmental venous anomaly coursing cranially.2.Additional stable small avidly enhancing vascular malformation located within the right superior frontal gyrus with chronic hemosiderin deposition.3.Persistent right paranasal sinus disease as above.
