We report a 40-year-old woman who presented with acute intractable neck pain and lateral cervical bending. Investigations with neuroimaging revealed evidence of thrombosis in her right transverse and sigmoid sinuses. The precipitating factors for the thrombosis were consumption of oral contraceptive pills during the month of Ramadan, and dehydration due to fasting. The patient immediately was treated with the therapeutic dose of anticoagulant. We concluded that in patients with severe cervical pain, especially those who are predisposed to thrombotic complications, CVT should be considered in the differential diagnosis. https://crcp.tums.ac.ir/index.php/crcp/article/view/186 https://crcp.tums.ac.ir/index.php/crcp/article/download/186/105
