Sonographic appearance of a postpartum pyomyoma with gas production.

Pyomyoma or suppurative leiomyoma is a potentially fatal complication of uterine leiomyomas. It is a rare condition with only a small number of reported cases since the era of antibiotics, and the descriptions of its sonographic appearance has been limited. We present a case of a pyomyoma associated with gas production, including a brief review of the reported sonographic features.
