  • In surgical planning of the parasagittal meningioma, invasion and occlusion of the superior sagittal sinus are important factors. When tumor is located within anterior 1/3, or when angiographic finding shows total occlusion of superior sagittal sinus, it is regarded that the ligation of superior sagittal sinus is safe. We report a case of parasagittal meningioma in 59-year-old male patient with complete occlusion of superior sagittal sinus which was confirmed by preoperative angiography, who developed temporary neurologic deterioration after superior sagittal sinus ligation and resection.

  • A case of parasagittal meningioma en plaque with a peculiar clinical presentation is reported with a review of the literature. A 72-year-old woman presented with dysphasia and right hemiparesis. Computed tomography and magnetic resonance imaging demonstrated focal edema of left frontal lobe and a thick sheet-like parasagittal enhancing lesion with extension along the falx cerebri and adjacent sulcal enhancement. Differential diagnosis included idiopathic hypertrophic pachymeningitis, meningeal neurosarcoidosis, metastasis and meningioma en plaque. Cerebral angiography revealed occlusion of the anterior one-third of the superior sagittal sinus as well as a faint tumor blush supplied from the anterior branch of the middle meningeal artery. At surgery, the tumor invading the dura and skull was removed totally but the tumor invaded into the superior sagittal sinus was removed subtotally. The tumor was confirmed to be a transitional meningioma on pathological examination.

  • A 66-year-old woman presented with intermittent paraparesis and generalized tonic-clonic seizure. Cerebral angiography demonstrated dural arteriovenous fistula (AVF) involving superior sagittal sinus (SSS), which was associated with SSS occlusion on the posterior one third. The dural AVF was fed by bilateral middle meningeal arteries (MMAs), superficial temporal arteries (STAs) and occipital arteries with marked retrograde cortical venous reflux. Transfemoral arterial Onyx embolization was performed through right MMA and STA, but it was not successful, which resulted in partial obliteration of dural AVF because of tortuous MMA preventing the microcatheter from reaching the fistula closely enough. Second procedure was performed through left MMA accessed by direct MMA puncture following small decortications of cranium overlying the MMA using diamond drill one week later. Microcatheter could be located far distally to the fistula through 5 F sheath placed into the MMA and complete obliteration of dural AVF was achieved using 3.9 cc of Onyx.

  • While a delayed intracerebral hemorrhage at the site of a ventricular catheter has occasionally been reported in literature, a delayed hemorrhage caused by venous infarction secondary to ventriculoperitoneal shunting has not been previously reported. In the present case, a 68-year-old woman underwent ventriculoperitoneal shunting through a frontal burr hole, and developed a hemorrhagic transformation of venous infarction on the second postoperative day. This massive venous infarction was caused by bipolar coagulation and occlusion of a large paramedian cortical vein in association with atresia of the rostral superior sagittal sinus. Thus, to eliminate the risk of postoperative venous infarction, technical precautions to avoid damaging surface vessels in a burr hole are required under loupe magnification in ventriculoperitoneal shunting.
