[Tumor enucleation for intrapelvic schwannoma: a report of two cases].
A 65-year-old man and a 35-year-old woman were diagnosed with intrapelvic tumors originating from the sacral nerves by computed tomographic (CT) scan, magnetic resonance imaging (MRI) and angiography. These tumors were tightly adhered to the iliac arteries and veins and could not be resected completely. Since the cryostat sections revealed benign schwannomas histopathologically, we enucleated the tumors without the pseudocapsules. All of the 57 intrapelvic schwannomas previously reported in Japan were resected with pseudocapsules. Both of our patients showed improvement of subjective symptoms, but should be followed up and examined for the presence of regrowth of tumors.
