Sonographic and Magnetic Resonance Imaging Findings of an Isolated Vaginal Leiomyoma

Leiomyomas represent the most common uterine neoplasms, noted clinically in 20% to 30% of all women older than 30 years, and are found in 75% of hysterectomy specimens. 1 Although rare, the most common mesenchymal neoplasm of the vagina is the leiomyoma. 2 The mean patient age at detection of a vaginal leiomyoma, is approximately 40 years, with a reported range between 19 and 72 years. 2 Vaginal leiomyomas vary from 0.5 to 15 cm in diameter, averaging approximately 3 cm in size, and may occur anywhere within the vagina, usually in a submucosal location. Although these rare lesions are often asymptomatic, larger tumors may be associated with pain, dystocia, dyspareunia, or obstructive urinary symptoms. We report the sonographic and magnetic resonance imaging (MRI) findings of a patient with an isolated vaginal wall leiomyoma.
