A case of Trousseau syndrome: Screening, detection and complication

Trousseau syndrome (TS) is a malignant tumor-mediated complication of the hypercoagulable state with an unknown etiology. Laboratory testing results in patients with TS have indicated elevated D-dimer levels. The imaging analysis in patients who had undergone stroke has shown the presence of several cerebral infarction lesions in multiple regions. Since patients have had malignant tumors for a long time when they suffer from a secondary stroke, the optimum time for radical tumor treatment is usually missed. This study reports a case to improve the early screening and detection of TS and reduce the risk of recurrence of cerebral infarction.
