[Transient homonymous hemianopsia due to thrombosis of the confluence of sinuses after occipital transtentorial removal of pineal region tumor].
The authors report a case of 74-year-old woman suffering thrombosis of the confluence of sinuses after the left occipital transtentorial removal of a pineal region epidermoid cyst. Four days after the operation, the patient developed left homonymous hemianopsia. Magnetic resonance imaging revealed a venous infarct in the right occipital lobe and magnetic resonance venography disclosed a signal defect of the posterior part of the confluence of sinuses. The patients' neurological symptom recovered soon after anticoagulation treatment, and magnetic resonance venography after the sixth week showed recanalization of the confluence of sinuses. Although it might be rare, thrombosis of the dural sinus should be recognized as a complication of craniotomy.
