An adenochondroma is a hamartoma - a benign mass of disorganized tissue - specifically comprising glandular and cartilaginous tissue.

A phakoma, or phacoma, is a type of tumor. It is a hamartoma found in phacomatosis.

A hamartoma is a benign malformation resembling a tumor and resulting from faulty development in an organ. It is an overgrowth of mature cells normally found in the affected part. It is composed of an abnormal mixture of tissue elements that develop and grow at the same rate as normal elements but are not likely to compress adjacent tissue. The error here is often in the quantity, the structure, and/or the level of maturation of the tissue components.

A nuero oncologist told me the area of the right cerebral peduncle affects your cranial nerve function. More than likely visual disturbances. I can see it causing a learning disability if dyslexia is possibly present. Does not cause depression. Per my Dr at the Kirkland clinic at UAB.

I had this problem about 25 years ago....before widespread use of CAT scans and before the invention of the MRI A small tumor, a hamartoma, was found after extensive X rays in the musculature controlling the vocal cord I had surgery to remove it with good results. Later, I experienced serious voice weakness, as there may have been damage in the imprecise effort to excise the tumor. There was significant dyssymmetry in the vocal cord movement. The doctors could never could determine the reason, except the surgery damage theory. I had medialization thyroplasty to "shim" the weaker vocal cord toward the mid-line with good results. At present, I have a strong voice but this is because each morning I inhale water in the shower to "wash off" the vocal cords. In other words, the acccumulation of phlegm overnight is not moved away normally by my vocal cord movement---so I do it artificially with the hot shower water. After my experience, I am convinced that quite a number of people to not have perfect vocal cord symmetry. Beware, many speech therapists and EMTs are not very aware of these procedures I recommend contact with Dr. Albert Merati at the University of Washington Roger in Wichita
