Sinus pericranii with severe symptom due to transient disorder of venous return--case report

The authors report a case of sinus pericranii in a 22-year-old female presenting with severe headache, vomiting, bradycardia, and bradypnea following excessive distention of the tumor. After tumor removal, the symptoms were completely relieved. The symptoms were thought to be due to transient impairment of blood flow in the superior sagittal sinus.
