Venous sinus thrombosis is a relatively uncommon disorder that frequently is associated with confusing clinical findings and delayed diagnosis. Patients are often screened with unenhanced CT, and CT findings may be subtle and may include hyperattenuation of cerebral veins or venous sinuses secondary to intracranial thrombosis. This hyperattenuation may be mimicked by polycythemia, as shown in this case.
静脉窦血栓形成是一种相对罕见的疾病，常伴有令人困惑的临床表现和诊断延迟。患者通常首先接受平扫CT检查，CT表现可能不明显，可能包括颅内血栓形成继发的脑静脉或静脉窦高密度影。如本病例所示，红细胞增多症可能会模拟这种高密度影。
