Background: The trigeminocerebellar artery (TCA) is a branch of the basilar artery supplying both the trigeminal nerve root and the cerebellar hemisphere. Despite its proximity to the trigeminal nerve, only a few cases of trigeminal neuralgia (TN) caused by TCA compression of the trigeminal nerve have been reported. Moreover, TN caused by blood vessel penetration of the trigeminal nerve is very rare.

Case Description: A 24-year-old female was admitted to our department because of right sided partial seizure and acute or subacute subdural hematoma over the left cerebral convexity.
A polyethylene glycol (PEG) hydrogel sealant recently has been approved as an adjunct to sutured dural closure in Japan. We treated consecutive six patients with PEG hydrogel sealant in posterior fossa operation. Three of six cases suffered delayed cerebrospinal fluid (CSF) leak after watertight dural closure with the PEG hydrogel sealant, although there was no leak case which was treated with fibrin glue, before 2 years until the adoption of the new material.

Materials And Methods: Diffusion tensor image (DTI) data of the rat (postnatal 1-10 weeks) corpus callosum were obtained with a 7.0 T MR scanner.
Tissue plasminogen activator (tPA) levels were investigated in the cisternal fluid of patients with subarachnoid hemorrhage treated with single intracisternal injection of recombinant tPA during radical surgery for ruptured aneurysms. Seven patients received different doses of tPA: two of 400 microg/ml, three of 500 microg/ml, one of 700 microg/ml, and one of 800 microg/ml in a total amount of 20 ml distilled water at pH 7. Cerebrospinal fluid samples were taken directly from the cisternal fluid at 15-minute incubation after injection, immediately after irrigation during surgery, and by lumbar tap 2 days after surgery.
