What post-surgery complication is present?
Dense right internal jugular vein is noted and is highly suspicious for thrombosis.
What kind of surgical approach was used to remove the right cerebellopontine angle?
Translabyrinthine approach.
Translabyrinthine approach craniotomy and resection of the right acoustic neuroma noted with expected postoperative changes, including a small amount of pneumocephalus. Grey-white matter differentiation is preserved. Ventricles and basal cisterns are normal. No midline shift or cerebral herniation.
Dense right internal jugular vein highly suspicious for thrombosis; right sigmoid and transverse sinuses are unremarkable for a noncontrast study.
Conclusion: Features suggestive of right internal jugular vein thrombosis.
