Venous distention sign of intracranial hypotension

Case contributed by Dr Stavroulis Manos

Presentation

Low grade headache only

Patient Data

Age: 50
Gender: Male

MRI 1.5 Tesla + C

Modality: MRI

Patient with headache resistant to the therapy and persistent for over one month.

The MRI scan showed subdural bilateral and symmetric fluid with imaging intensity higher than the CSF liquid and no hemorrhagic signs.

After iv contrast injection there was no sign of leptomeningeal or parenchymal enhancement but only a homogeneous and symmetric dural enhancement. On the sagittal images you can note a round shape of the inferior border of the transverse venous sinus  (venous distension sign ) and a reduction of the distance between the optic chiasma and the pituitary gland.
