Recurrent cerebral embolism due to the disseminated carcinomatosis of bone marrow with early gastric cancer

Abstract

A 67-year-old woman who had undergone laparoscopic proximal gastrectomy for early gastric cancer 10 months previously was admitted to our hospital due to dysarthria. Brain MRI demonstrated acute multiple small infarcts in the right middle cerebral artery (MCA) and the right posterior inferior cerebellar artery (PICA) territory, and she was diagnosed as embolic stroke. Anticoagulant therapy did not prevent further ischemic stroke. No embolic sources were detected by MR angiography, carotid duplex sonography, transthoracic and transesophageal echocardiography, and Holter electrocardiography. We also performed upper gastrointestinal endoscopy and contrast-enhanced CT of the thoracoabdominal area, but there was no evidence of local recurrence or lymph node metastases of gastric cancer. As the ALP and D-dimer levels were gradually increasing, we performed PET/CT, which revealed fluorodeoxyglucose (FDG) uptake in the vertebra bone, and disseminated carcinomatosis of bone marrow with early gastric cancer was diagnosed after bone marrow biopsy on Day 41. After undergoing chemotherapy, she had no further stroke and died on Day 207.
