 Redemonstrated is a mixed signal T1 and T2 intensity lesion within the medial rolandic brain involving both sensory and motor cortices, measuring 17 mm AP by 13 mm transverse dimensions (as measured on axial T2 technique), unchanged in size or morphology. This is associated with susceptibility hypointense abnormality, however without perilesional edema. Postcontrast images demonstrate an associated developmental venous anomaly which drains posteriorly, superiorly, and medially. There are no other foci of susceptibility abnormality.The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There are no other masses, mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for acute intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. The paranasal sinuses and mastoid air cells are clear.
Stable cerebral cavernous malformation involving left medial rolandic brain involving both sensory and motor cortices with an associated developmental venous anomaly.
