Brain MRI finding:Multiple small Cavernous Hemangiomas |

Dear Ask The Doctor: MRI Report Can you tell me what this all means and is it something to be concerned about? Multiple tiny areas of punctate gradient signal hypointensity within the left cerebellum and also dorsal left pons. Some of these areas are calcified on the recent CT. Gradient signal hyperintensity may correspond to the presence of calcification. Some lesions demonstrate blooming consistent with blood products. These leasions are predominately rounded and well circumscribed and may represent MULTIPLE SMALL CAVERNOUS HEMANGIOMAS. No flow voids are noted to suggest an AVM. Some lesions are surrounded by T2 signal hyperintentensity which may realte to mild edem. This is most notable in the left anterior and lateral aspec of the cerebellar hemisphere and posterior inferior left cerebellum. No significant mass effect. Dear Dee: The cavernous hemangiomas are congenital, intracranial vascular malformations; these abnormal vascular connections may tend to enlarge over the time. They can run in the family. Sometimes they do not produce any symptoms or may produce headaches, seizures or small local hemorrhages. Most cavernous hemangiomas may simply be followed up over time, but if they begin to cause symptoms or growing producing some kind of mass effect on the other structures, then, the surgical removal may be considered as a treatment option. In your case they are small and they are no producing mass effect, so I recommend you at this time just keep follow up, but if you start to have any symptoms as persistent headaches or seizures you should get an immediate evaluation by a neurosurgeon. |
