Sigmoid Sinus Thrombosis with Mastoiditis

Cerebral venous thrombosis often presents with hemorrhagic infarction in areas atypical for arterial vascular distribution. Magnetic resonance venography (MRV) in conjunction with conventional MRI can accurately diagnose cerebral venous thrombosis. In this case of a 14 yr old child who presenterd fever, headache, vomitting MRI and MRV were done. On MRI fluid signal in the left mastoid sinus is noted suggesting mastoiditis. Involvement of the sinus due to adjacent infectious process is a known cause for venous sinus thrombosis. Also noted in left temporoparietal haemorrhagic infarction. High signal is noted in the sinus on conventional MR images and diagnosis was confirmed on MRV.
