To report a superior sagittal sinus thrombosis occurring as a rare complication of neck dissection, and to present a review of published literature.


A 42-year-old man underwent an elective neck dissection for a tumour stage 2, node stage 2b, tonsillar squamous cell carcinoma, prior to chemoradiotherapy. During surgery, the right internal jugular vein was sacrificed as part of the resection, as tumour was adherent to it. Two weeks after surgery, the patient was readmitted with seizures. Subsequent computed tomography and magnetic resonance venography confirmed a superior sagittal sinus thrombosis. The patient was subsequently anticoagulated and underwent radiotherapy without further complication. A review of pre-operative imaging indicated a dominant internal jugular vein, ligation of which may have been a factor in the subsequent sagittal sinus thrombosis.


Superior sagittal sinus thrombosis following neck dissection is a rare occurrence, with little reported in the literature. Dominant internal jugular vein anatomy may be evident on pre-operative imaging. An awareness of this complication may be helpful to surgeons contemplating sacrifice of the internal jugular vein.
