Sinus thrombosis, which causes pseudotumor cerebri, is difficult to diagnose with conventional imaging apparatus, CT and MRI. We report a case of sinus thrombosis due to Behçet's disease diagnosed by magnetic resonance angiography (MRA). A forty-five-year old man with severe headache and ocular pain was examined. Since he had a history of oral ulcers, genital ulcers, and erythema nodosum venous thrombosis, he had been diagnosed as having Behçet's disease previously. He showed marked papilledema bilaterally but no obvious intracranial lesion was observed by CT and MRI. On MRA, an obstruction was apparent at the sagittal sinus. Anticoagulant and steroid therapy were effective to relieve the headache, and to improve the constricted visual field temporarily. By MRA, blood flow was confirmed in the sagittal sinus. However, mild papilledema persisted and finally vision was lost because of optic atrophy.
导致假性脑瘤的静脉窦血栓形成，难以通过传统成像设备CT和MRI进行诊断。我们报告一例通过磁共振血管造影（MRA）诊断出的白塞病所致静脉窦血栓形成病例。对一名患有严重头痛和眼痛的45岁男性进行了检查。由于他有口腔溃疡、生殖器溃疡和结节性红斑静脉血栓形成的病史，此前已被诊断为白塞病。他双侧出现明显的视乳头水肿，但CT和MRI未观察到明显的颅内病变。在MRA上，矢状窦处可见梗阻。抗凝和类固醇治疗有效缓解了头痛，并暂时改善了缩窄的视野。通过MRA，证实矢状窦内有血流。然而，轻度视乳头水肿持续存在，最终因视神经萎缩而失明。
