Background: The Cavernous Angioma in Posterior Sagittal Sinus is exceedingly rare.
Methods: We report for the case of a 10-year-old male patient who was diagnosed with Cavernous Angioma in Posterior Sagittal Sinus.
Results: Our case is the second reported case of Cavernous Angioma in Posterior Sagittal Sinus in the world.
Conclusions: It is very rare for the cavernous hemangioma to occur in the sinus, preoperative conventional MR scan lacks specificity and easily leads to misdiagnosis. Head MR enhancement, MRBTI, and SWI can provide more useful diagnostic information. The final diagnosis depends on the pathology examination.
