Medical Must-See: The largest documented primary ovarian tumour

Doctors said it was the first such case to present with lower-limb weakness, paresis and urinary incontinence caused by lumbosacral nerve compression.

Doctors have reported the largest case of ovarian leiomyoma, in an Iranian woman who died from postoperative complications.

Ovarian leiomyomas account for 0.5-1% of benign ovarian neoplasms, the doctors said. Other recent studies counted fewer than 100 published cases.

Their patient, aged 64, presented with a three-month history of lower-limb weakness, paresis and urinary incontinence, which had worsened in the past fortnight.

She was nulliparous, taking aspirin and clopidogrel, and had experienced a stroke two months earlier, they wrote in Clinical Case Reports.
