Her medical history was unremarkable, and on physical examination, hemiparesis and hyperreflexia on the left side were found. MRI of the brain showed multiple areas of restricted diffusion in both parietal lobes and in the cerebellum, consistent with embolic shower. Magnetic resonance angiography showed no abnormal findings. A contrast-enhanced CT scan revealed multiple pulmonary emboli. Abdominal MRI showed a 135\u2009mm left ovarian tumour composed of a solid and a cystic component with liquid level formation. After a total hysterectomy and bilateral adnexectomy, the histopathology confirmed a seromucinous borderline tumour. Therefore, the patient was diagnosed with Trousseau\u2019s syndrome associated with an ovarian seromucinous borderline tumour. To our knowledge, this is the first report mentioning a borderline ovarian tumour detected as Trousseau\u2019s syndrome.<\/jats:p>","DOI":"10.1136\/bcr-2021-244249","type":"journal-article","created":{"date-parts":[[2021,8,24]],"date-time":"2021-08-24T12:41:05Z","timestamp":1629808865000},"page":"e244249","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Trousseau\u2019s
