Abdominal US disclosed an enlarged uterus with loss of endometrial stripe and hypoechoic fluid collection with hyperechoic component in the uterine cavity, suggestive of pyometrium.

Computed tomographic scans showed marked dilation of the uterus with hypodense fluid accumulation. Several hyperdense nodules with discontinuity of the adjacent enhanced mucosa (arrow) were noted that focal rupture of the uterine wall was suspected.
Pyometra is an uncommon disease, referring to accumulation of pus in the uterine cavity [1]. It mostly occurs in postmenopausal women. The classic symptoms of pyometra (lower abdominal pain, purulent vaginal discharge, and enlarged uterus) are nonspecific and easily misdiagnosed as other causes of acute abdomen [1-3]. We report 7 cases with pyometra during a 5-year period. Four cases were diagnosed as urinary tract infection (UTI) initially, and pyometra was diagnosed by imaging studies. All had favorable outcomes, but 1 died because of delayed diagnosis.
