Case Reports Comparative StudyCT and MRI findings in a case of pelvic schwannoma.
We compared the diagnostic utility of computed tomography (CT) and magnetic resonance imaging (MRI) in a patient with a pelvic schwannoma. This 46-year-old woman was admitted for evaluation of a retroperitoneal pelvic mass and myoma uteri. The retroperitoneal pelvic mass had been detected by a CT scan at a routine health examination. ⋯ Small areas of low intensity inside the tumor were observed on T2-weighted images. Histological examination revealed a typical schwannoma of mixed Antoni type A and type B. These findings indicate that both MRI and CT are useful for diagnosis of retroperitoneal schwannomas.
