Occurrence of superior sagittal sinus and
straight sinus were persistent in all the patients.
Deep Cerebral Veins and
Straight Sinus have Low Signal Intensity on SWI (Susceptibility Weighted Image)
We presented a case of meningococcal meningitis with thrombosis of the
straight sinus. The patient was managed with antibiotic therapy and made a complete recovery.
These scans demonstrate dense clot sign which show a dark area (yellow arrows) where the infarct of the left thalamus is located due to thrombosis of internal cerebral veins and
straight sinus (red arrows).
Cerebral artery MR angiography, bilateral carotis arteries, anterior cerebral artery, pericallosal artery and mid cerebral artery, Willis Polygon arterial structures, basilar artery, and arteria cerebri posterior branches were normal; no aneurysm, malformation or displacement were detected; venous MR angiography revealed a slightly weakened right transverse sinus calibration (variation) and normal sagittal sinus,
straight sinus, left transverse and sigmoid sinus alignments and calibrations.
The patient underwent computed tomography (CT) scan of the head, which showed obstructive hydrocephalus and an aneurysmally dilated vein of Galen, a stenotic
straight sinus, and a distended torcular Herophili.
