52 year old patient with cerebral cavernous malformations. Annual surveillance. Redemonstrated are numerous supratentorial and infratentorial foci of susceptibility effect related to numerous bilateral cavernous malformations, as demonstrated previously. The largest of these lesions are located the left dorsolateral thalamus into the centrum semiovale measuring up to 33 mm, spanning the superior and middle temporal gyri posteriorly as well as within the right lateral pons adjacent to the fifth cranial nerve root measuring up to 7 mm, unchanged. No lesions demonstrate perilesional edema. There appear to be developmental venous anomalies associated with the larger lesions. There are no signal characteristics suggestive of acute hemorrhage. There is no hydrocephalus or ischemia. Also redemonstrated is mild pansinus mucosal thickening. Mastoid air cells are clear. Expected vascular flow voids are demonstrated.
No significant interval change of numerous supratentorial and infratentorial cerebral cavernous malformations.
