Idiopathic intracranial hypertension (IIH) has been associated with transverse sinus stenosis in a number of cases. Some authors advocate for stent placement when transverse sinus stenosis is responsible for pseudotumor symptoms. A 19-year-old man with IIH, bilateral transverse sinus stenosis was apparent on a CT venography, with reconstitution of the lateral sinus. MRI was then performed, and transverse sinus stenosis was confirmed. An impressive network of dilated collateral veins became apparent on VENBOLD sequences. Treatment options in this case include cerebrospinal fluid (CSF) shunting, optic nerve fenestrations and transverse sinus stenting. A ventriculoperitoneal shunt was placed in this patient, with prompt resolution of pseudotumor symptoms.
