Obliteration of giant corpus callosum AVM with linac based stereotactic radiosurgery

Successful management of large AVMs is difficult. Traditionally they are considered less responsive and even unsuitable for radiosurgery. This case report demonstrates total angiographic obliteration in a complex, large corpus callosum AVM (volume 36.52 cc) in a 39-year-old male. Stereotactic radiation was delivered with a Linear Accelerator using ultra conformal treatment planning. Large volume AVMs can be subjected to stereotactic radiosurgery if the shape and location makes it possible to deliver an adequate radiation dose.
