Trousseau syndrome

Description

A 45-year-old woman was admitted to our hospital because of impaired consciousness. She had a huge tumour measuring 10 inches in diameter on the left breast (figure 1A). Although the tumour had been increasing in size since 3 years, the patient had adamantly refused to visit a hospital. She had no history of hypertension or atrial fibrillation. Symmetrical high-intensity lesions in the thalamus were observed on MRI (diffusion-weighted images) (figure 1B, arrow). Enhanced chest CT imaging revealed a large tumour on the left breast (figure 1C, arrowheads) with metastases in the lymph nodes and lungs (figure 1C, arrows) as well as cardiac invasion. Breast mass biopsy revealed the tumour to be a mucinous carcinoma. Impaired consciousness was considered to be caused by bilateral paramedian thalamic infarction.
