Ruptured aneurysm at the choroidal branch of the posterior inferior cerebellar artery: a case report and review of the literature.

Background: The authors present a rare case of a ruptured aneurysm at the choroidal branch of the posterior inferior cerebellar artery (PICA).

Case Description: A 77-year-old female was admitted to our institute because of sudden onset of severe headache and vomiting. Radiologic examination revealed intraventricular hemorrhage caused by rupture of the aneurysm at the choroidal branch of the PICA.

Giant fusiform aneurysms in the middle cerebral artery presenting with hemorrhages of different origins. Report of three cases and review of the literature.

Three cases of giant fusiform aneurysms in the middle cerebral artery (MCA) presenting with hemorrhages of different origins are reported, and appropriate literature is reviewed to investigate the characteristics of these lesions. Two patients had suffered a subarachnoid hemorrhage and the other had an intramural hemorrhage (dissection). Pathologically, these aneurysms presented with hemorrhages of different origins; classic rupture type (Case 1), dissection type (Case 2), and atherosclerosis-related thrombosis type (Case 3).

We investigated the efficacy of percutaneous endoscopic gastrostomy (PEG) in neurosurgery. PEG was applied 94 feeding patients using One-Step Button. The mean age was 70.

[A case of pituitary apoplexy with severe consciousness disturbance following mild head trauma].

A rare case of pituitary apoplexy following mild head trauma is reported. A 56-year-old woman was referred to our hospital for loss of consciousness following a traffic accident. Magnetic resonance (MR) imaging showed a large suprasellar tumor containing a low intensity area on the T 1-, T 2-weighted images and fluid-attenuated inversion recovery (FLAIR) image.

A case of malignant melanoma in the paranasal sinuses, successfully treated with gamma knife stereotactic radiosurgery, is reported. A 90-year-old man with left periorbital swelling was referred to our hospital for gamma knife radiosurgery. He had a 4-month history of left periorbital swelling and ophthalmalgia, but he was treated conservatively due to his age.

[Giant fusiform aneurysm with dissection in the middle cerebral artery: a case report].
