| Résumé: | Central venous stenosis is a relatively common complication in hemodialysis patients; however,
jugular venous reflux (JVR) and increased intracranial pressure are rare, and associated progressive
visual disturbance was reported in only a few cases. Here, we report a case of JVR with
visual disturbance and increased intracranial pressure. Notably, the MRI was accompanied by a
dilatation of the superior ophthalmic vein, which was mistaken for a cavernous sinus dural arteriovenous
fistula (CSdAVF). The patient had JVR on time-of-flight MR angiography (TOF-MRA)
and severe stenosis of the left brachiocephalic vein on conventional angiography. After balloon
angioplasty for central venous stenosis, he was discharged after improvement of his visual disturbance.
Although JVR due to central venous stenosis and CSdAVF might show similar symptoms,
treatment plans are different. Therefore, it is important to distinguish radiologically based
on a thorough review of MRI and TOF-MRA and confirm the central venous stenosis on cerebral
angiography for the accurate diagnosis. |
