title: Mixed tumor of the vagina: sonographic and magnetic resonance imaging findings.
abstract: Mixed tumor of the vagina is a rare benign neoplasm that is composed of epithelial and mesenchymal cells. The majority of tumors are asymptomatic and simple tumor excision is curative. We report a case with pathological confirmation that was seen in a 42-year-old woman. On ultrasound examination the lesion appeared as an ovoid hypoechoic mass, 2.0 x 2.7 cm in size, arising from the lower third of the vagina. The lesion was well defined, solid and showed diffuse hypervascularity on color flow images. Magnetic resonance imaging of the pelvis showed a well-circumscribed ovoid mass (2.0 x 2.5 cm) on the left lateral vaginal wall. On T2-weighted images the mass appeared as a homogeneous hyperintense lesion, while on T1-weighted images it was difficult to discern the mass from the vaginal wall. After intravenous administration of gadolinium the mass showed progressively increasing homogeneous enhancement. The lesion was excised without complication and there was no evidence of recurrence at the 10-month follow-up.
