45 year old woman with anaemia and menorrhagia for the past year.
The enlarged, globular uterus shows a large, well-circumscribed, firm, ovoid mass in the myometrium. Cut surface shows a tan, whorled appearance with no necrosis or haemorrhage. The endometrial cavity is compressed and distorted. A much smaller intramural nodule of similar nature is seen in the opposing myometrium.
