Cerebral Venous Sinus Thrombosis in a Patient with Appendicular Abscess.

Abstract

Acute appendicitis is a common abdominal emergency, while cerebral venous sinus thrombosis (CVST) is a rare cerebral vascular disease. Cases of CVST in patients with appendicitis have not been reported in the literature. We present a case of CVST in a patient with appendicular abscess. A 56-year old man presented to our department with a headache for 6 days; he had a history of abdominal pain 15 days before admission. Abdominal contrast-enhanced computed tomography revealed appendicular abscess. Head magnetic resonance venography and contrast-enhanced magnetic resonance imaging showed thrombosis in the left transverse and sigmoid sinus. Antithrombotic treatments were administered, and antibiotic treatments and puncture and drainage were used to treat the appendicular abscess. The patient's headache disappeared after 10 days of treatment, and he had recovered well clinically at 3-month follow-up. CVST after acute appendicitis is rare, and clinicians should be aware of this complication when suspicious symptoms occur. The underlying mechanisms require further investigation.
