Clinical question: Assess probable cavernoma. Signs and symptoms: None Pre-and post-enhanced brain MRI:No evidence of restricted diffusion.Examination demonstrate two round foci of susceptibility and T2-hypointensity in the inferior left cerebellum highly suggestive of cavernous malformation. The lesions measure both at approximately 8.6 mm in size. There is evidence of a large associated developmental venous anomaly of the left cerebellum occupying a large segment of the cerebellum. Post-enhanced images demonstrate enhancement of this large developmental venous. The appearance the developmental venous anomaly on post enhanced images is suggestive of possibly two separate developmental venous anomaly. The largest developmental venous anomaly appears to extend inferiorly and to the midline and is smaller more superior located venous anomaly extends superiorly to the level left tentorial leaf. There is no evidence of prior hemorrhage, parenchymal edema or encephalomalacia with this finding. The fourth ventricle remains within normal and in midline. No evidence of any additional cavernoma.There is a thin band of T2/T2 flair hyperintensity in the left frontal lobe extending from the cortex to the left lateral ventricle without abnormal enhancement. This finding is new since prior exam from Silver Cross hospital dated 11 -- 26 -- 14. Findings to represent a nonspecific focus of encephalomalacia/gliosis.The anatomical morphology and signal intensity brain parenchyma is otherwise within normal on all MRI sequences and without detectable abnormal enhancement.Unremarkable calvarium and soft tissues of the scalp.Unremarkable images through the orbits and including axial fat sat post enhanced series.All paranasal sinuses and bilateral mastoid air cells and middle ear cavities demonstrate normal pneumatization signal pattern.
1.Two small (both approximately at 8.6-mm) cavernomas in the left cerebellum are identified. There is a large single or more likely two adjacent developmental venous anomaly associated with the cavernomas detected. No evidence of associated hemorrhage, surrounding edema or encephalomalacia is present. No significant change since prior study.2.Nonspecific linear encephalomalacia in the left frontal lobe which is new since prior MRI exam from 11 -- 26 -- 14.3.Unremarkable pre-and post enhanced brain MRI otherwise.
