UTERUS & CERVIX - Haematometria secondary to scarring

The cut surface shows a cavity some 4.0 x 2.0 cm in the fundus, apparently almost completely separated from the cervical canal by an area of scar tissue.
This woman presented with a regular menstrual cycle but with irregular loss with spotting and occasional flooding relieved by progestogen therapy. Examination showed a retroverted uterus. In the past she had had a caesarian section for a transverse lie. It is assumed that the scarring is secondary to the surgical intervention.
