Isolated lateral sinus thrombosis presenting as cerebellar infarction in a patient with iron deficiency anemia

Abstract

As a rare cerebrovascular disease, cerebral venous thrombosis (CVT) is caused by various conditions including trauma, infection, oral contraceptive, cancer and hematologic disorders. However, iron deficiency anemia is not a common cause for CVT in adult. Posterior fossa infarction following CVT is not well demonstrated because posterior fossa has abundant collateral vessels. Here, we report a case of a 55-year-old man who was admitted with complaints of headache, nausea, and mild dizziness. The patient was diagnosed with isolated lateral sinus thrombosis presenting as cerebellar infarction. Laboratory findings revealed normocytic normochromic anemia due to iron deficiency, and the patient's symptoms were improved after iron supplementation. © 2013 The Korean Neurosurgical Society.
