Sonographic appearance of endometrial osseous metaplasia.

Osseous metaplasia of the endometrium is a rare condition characterized by the presence of mature or immature bone in the endometrium. Most cases present with secondary infertility following an abortion or chronic endometritis. Some patients are asymptomatic, while others have menstrual abnormalities such as menorrhagia or oligomenorrhea.

Sonography of postpartum uterine inversion from acute to chronic stage.

We report the sonographic appearance of postpartum uterine inversion progressing from acute partial to chronic stage after an 8-week interval. The delay in diagnosis was partly due to the patient's stable clinical condition except for minor vaginal discharge and bleeding. The diagnosis of chronic inversion on the follow-up sonographic examination prompted clinicians to undertake surgical repair.

Sonographic diagnosis of inferior mesenteric artery aneurysm and marginal artery of Drummond.

We report the case of a patient in whom sonographic examination revealed an aneurysm of the inferior mesenteric artery with severe proximal stenosis and poststenotic dilatation--the enlargement of the proximal portion of the artery of Drummond. This collateral pathway should be kept in mind when studying bowel ischemia, especially when stenosis is present or when there is occlusion of the superior mesenteric artery.
