title: Clinicopathological features of intraorbital neurinoma--report of two cases.
abstract: Clinicopathological features of intraorbital neurinomas were investigated in two patients. Magnetic resonance imaging (MRI) findings in Case 1 were similar to those in Case 2. The central region of the neurinomas showed a slightly high intensity area with a marginal low intensity on T1-weighted images (T1WI), whereas on T2-weighted images (T2WI), the central area of the tumor was very low intensity with a marginal high intensity area. After gadolinium-DTPA (Gd-DTPA) injection, these areas were homogeneously enhanced in both cases. The deference in enhancement after Gd-DTPA injection reflected the distribution of cellularity and vessels in the tumor.
