Abstract |
Background: Cerebral venous sinus thrombosis is rare and might be overlooked by healthcare providers. It often occurs in the transverse sinuses, superior sagittal sinus, and the vein of Trolard. Sphenoparietal sinus (SPS) and/or superficial middle cerebral vein (SMCV) thrombosis is rare and only 12 cases reported in the literature.
Case description: We report a 47-year-old woman with iron deficiency anemia associated with myoma uteri who developed left SPS and SMCV thrombosis. She presented with sudden unconsciousness, right hemiplegia, and aphasia. Brain computed tomography showed subcortical hemorrhages in the left frontal and temporal lobes. Magnetic resonance imaging did not reveal the cause of the bleeding. Although antihypertensive treatment with nicardipine was initiated, she deteriorated into coma the next day and underwent emergency decompressive craniectomy. Thrombosis of the SMCV was identified during surgery. Re-examination of preoperative T2 star-weighted imaging revealed thrombosis of the SPS and SMCV.
Conclusion: All but one of the reviewed cases had the thrombosis develop on the left side, which may be attributed to anatomical and brain functional laterality. When an edematous change or cortical hemorrhage of unknown cause is encountered within the perisylvian region, especially on the left side, the possibility of SPS and SMCV thrombosis should be considered.
