Idiopathic intracranial hypertension (IIH) is defined as raised intracranial pressure of unknown etiology. Looking for underlying causes needs to be undertaken before the diagnosis is confirmed and managed accordingly. We are reporting a rare and unique case of a patient with the clinical diagnosis of idiopathic intracranial hypertension or pseudotumor cerebri. She is not obese and not taking any predisposing medication. Her first magnetic resonance imaging (MRI) and magnetic resonance venogram (MRV) were reported as showing left transverse sinus thrombosis. She was treated with anticoagulation. Her final diagnosis of left transverse sinus compression by a meningioma en plaque (MEP) was finally made with a repeat MRI. A high index of suspicion of unusual causes is important when IIH presents in an atypical patient or with an atypical presentation. The prognosis and management of real IIH and raised intracranial pressure due to other causes are different.
特发性颅内高压（IIH）被定义为病因不明的颅内压升高。在确诊并进行相应治疗之前，需要寻找潜在病因。我们报告一例罕见且独特的病例，该患者临床诊断为特发性颅内高压或假性脑瘤。她不肥胖，也未服用任何诱发药物。其首次磁共振成像（MRI）和磁共振静脉血管造影（MRV）报告显示左侧横窦血栓形成。她接受了抗凝治疗。最终通过重复MRI确诊为硬脑膜斑块状脑膜瘤（MEP）压迫左侧横窦。当非典型患者出现IIH或表现不典型时，高度怀疑不寻常病因很重要。真正的IIH与其他原因导致的颅内压升高的预后和治疗方法不同。
