Case 287

 This week, we present four cases with cerebellar-pontine angle epidermoid cyst (Fig. 1), hamartoma at globus pallidus (Fig. 2), sub-tentorial meningioma (Fig. 3) and neurinoma at cavernous sinus (Fig.4). Measuring ADC values, we discuss about the possibility of ADC value to contribute to the differential diagnosis.

What is an appropriate combination of ADC value on these tumors ?

A.　Epidermoid cyst: ADC value 0.713 B.　Hamartoma: ADC value 1.146 C.　Meningioma: ADC value 0.769 D.　Neurinoma: ADC value 1.362n

1.　A,B,C

2.　B,C,D

3.　A,C,D

4.　All
