Peduncolated Mixoyd Leiomyoma: MR Imaging and Spectroscopy

Abstract

Leiomyoma is the most common uterine tumor that occurs in more than 20% of women older than 30 years. This tumor presents different types of degenerations and a large variability in MRI imaging patterns. In literature ther is no case reported about leiomyomas spectroscopy. We report a case of 34 year-old woman who was admitted to the hospital for evaluation of an abdominal mass diagnosed at ultrasound. Physical examination revealed abdominal distension and abnormal uterine bleeding. Using abdominal MRI 3 Tesla we were able to determine the presence of a mass near uterine body very close to left ovarian. Laparotomy was performed and it showed a uterine peduncolated lesion. Histological examination proved smooth muscle cells and spindle-shaped cells separated by myxoid materials and ordinary myoma cells. This case report suggests that MR Spectroscopy may be able to allow distinction between benign and malignant lesions. It is important to differentiate leiomyomas from other diseases because of therapeutic treatment. In our case laparoscopic exeresis of the lesion permitted to preserve uterus and Patient's fertility.
