[|Human|] Had a bone scan recently.  Found an abnomanily in my skull.  (bone scan ordered because of problems with my foot)  Anyway given 3 probabilities  1)  hyperostosis,  2)  prominant venous lake and 3)  metastatic cancer.  Ive ruled out option 3,  but the venous lake thing has me wondering if you treat it.  And if you do, what kind of treatment?
[|AI|]  Hi, Thanks for writing in. Your CT scan shows an abnormality in the skull. It has been described as a possible likely(i) Hyperiostosis: this is a condition in which there is excess deposition of calcium and minerals on the bone surface. This can be due to many causes and is a usually a benign finding.(ii) Prominent venous lake: in this condition there nonproliferation vascular lesions that are not treatable via medical means. It is a blood filled space between the skull tables. No treatment is necessary/(iii) Metastasis: this is a sign of cancer spread. If you do not have any cancer in your body then this is least likely. Metastasis is not treatable.
