<unk>  <unk>  is a very aggressive form of<unk>  originally described as a variant of Wilms'<unk> , which is primarily a kidney<unk>  that occurs mainly in children.<unk>  was first described as a variant of Wilms'<unk>  of the kidney in 1978.<unk> s are a rare and highly<unk>  childhood neoplasm.<unk><unk> s outside the kidney were later reported in many tissues including the liver, soft tissue, and the central nervous system. Several cases of primary intracranial<unk>  have been reported since its recognition as a separate entity in 1978. The term<unk>  was used due to its similarity with rhabdomyosarcoma under the light microscope. The exact pathogenesis of<unk>  is unknown. The cerebellum is the most common location for primary intracerebral<unk>  (i.e., atypical teratoid<unk> <unk> . Biggs et al. were first to report a primary intracranial<unk>  around 1987. Although the cell of origin is not known, cytogenetic studies have suggested a common genetic basis for<unk><unk> s regardless of location with abnormalities in chromosome 22 commonly occurring.
