Acute abdomen caused by internodular bleeding from a multiple myoma pseudocapsule in a postmenopausal woman

BMJ Case Rep. 2023 Oct 4;16(10):e255230. doi: 10.1136/bcr-2023-255230.


A woman in her 50s presented with lower abdominal pain. She had a diagnosis of multiple uterine myomas 3 years earlier, followed by menopause. CT showed a pelvic mass of 19.5×9.4×10.2 cm in size, containing a haemorrhagic component. It was assumed that the tumour was the previously diagnosed myoma, and that it had increased to 150% of the size noted 3 years ago. An emergent hysterectomy was performed, and the pathological diagnosis was a uterine leiomyoma, with no components suggestive of sarcoma or degeneration. We witnessed a rare case of acute abdomen caused by internodular bleeding of multiple myomas. We assumed that the source of bleeding was the vessels of the myoma pseudocapsule. These cases may be more likely to occur in patients with multiple myomas presenting around the commencement of menopause. For symptomatic relief, emergent hysterectomy is considered to be the best treatment.
