[Case report of traumatic hemorrhage from the anterior choroidal artery].

Traumatic hemorrhage from the anterior choroidal artery is very rare. A 74-year-old male was admitted to our hospital immediately after a traffic accident. CT on admission showed right intracerebral hematomas in the posterior limb of the internal capsule and the upper part of the right cerebral peduncle.

[Isolated trigeminal sensory neuropathy due to pontine infarction of the root entry zone--report of two cases].

Secondary trigeminal neuralgia and isolated trigeminal neuropathy due to ischemic lesion of the pons are very rare. We report 2 patients with pontine infarct transecting the central trigeminal pathways resulting in trigeminal neuropathy and/or neuralgia. Case 1: A 48-year-old female presented with lancinating pain and paresthesia and hypesthesia in the right V2 and V3 distributions.

[Rapid disappearance of acute epidural hematoma by percutaneous aspiration of subperiosteal hematoma--case report].

We present the case of an 8-year-old boy who was injured in a bicycle accident and was admitted with a right frontal skull fracture, an acute epidural hematoma, a right frontal laceration, and a subperiosteal hematoma on admission. After the frontal cutaneous suture, the subperiosteal hematoma was aspirated by the percutaneous needle. Two hours later, a CT scan revealed that the epidural hematoma was disappeared.

[Conjugate deviation in ischemia of medial medullary oblongata--report of three cases].

Medial medullary infarct (MMI) is a rare type of brain stem infarction. Its clinical picture was characterized by contralateral hemiparesis, deep sensory disturbance, and ipsilateral hypoglossal paresis, but conjugate deviation or nystagmus is uncommon as initial symptom. Case 1: A 73-year-old man developed vomiting and vertigo.

[Paradoxical worsening ocular movement in idiopathic carotid-cavernous fistula without conjunctival congestion--case report].

We report a case of carotid-cavernous fistula(CCF) without conjunctival congestion and showing radiographically paradoxical worsening ocular movement. A 71-year-old woman suffered from mild double vision. The first carotid angiogram revealed left CCF, which was supplied by dural branches of the internal and external carotid arteries and drained out well via only the superior orbital vein to the angular vein.
