To explore the value of magnetic resonance imaging (MRI) in the posterior fossa occupying the position, 31 cases of posterior fossa occupying lesions were analyzed as follows: 1 Materials and Methods The group of 31 patients (16 males and 15 females), age 6 to 68 years old, an average of 38.4 years old. Duration of 1 week ~ 20 years, an average of 20.2 months, of which <6 months in 19 cases,> 7 months in 12 cases.
