Unique image findings around "kissing" distal anterior cerebral artery aneurysms in addition to perianeurysmal edema: A case report.

Background: Some aneurysms cause edema formation in the surrounding brain parenchyma and are thought to reflect various phenomena occurring in the aneurysm. Some authors highlighted perianeurysmal edema (PAE) as a finding that indicates higher risk of rupture of the aneurysm. On the other hand, there are no reports of image changes in the surrounding brain parenchyma of aneurysm other than edema formation.

The prevalence of calcification around odontoid process and the incidence of crowned dens syndrome in the neurosurgical ward: A single institution's analysis.

Objective: The objective of this study is to assess the prevalence and natural history of odontoid calcification and to identify factors related to its progression to crowned dens syndrome (CDS).

Methods: We reviewed a consecutive series of patients who underwent head CT upon admission to the neurosurgical ward of Niigata Prefectural Shibata Hospital. We evaluated the relationship between the presence of odontoid calcification and the patient's age, sex, and primary disorder for admission.

[Hydrocephalus Associated with Small Clinoidal Meningioma that Resolved after Tumor Removal:A Case Report].

Purpose: Small meningiomas causing hydrocephalus without obstruction of the ventricular system are rare. Herein, we report a case of small clinoidal meningioma with communicating hydrocephalus, which resolved after tumor removal.

Case Presentation: A 70-year-old woman presented with a 1-month history of memory disturbance followed by gait disturbance.

[Computed Tomography Criteria for Mild Head Trauma in Childhood: A Retrospective Study].

We retrospectively investigated 459 computed tomography (CT) scans of head injuries in children who were 7 years of age or younger that we experienced at our institute from 2008 to 2014, and investigated whether or not the algorithm created by the Pediatric Emergency Care Applied Research Network and the guidelines by the National Institute for Health and Care Excellence, which are the standards for CT scans of head injuries in infants, are adequate. As a result, all 12 cases that required surgery or resulted in serious brain damage fell into the category for CT recommendation according to both standards. Although several cases that fell into the category for consideration of CT involved intracranial lesions, all such cases were mild.

Efficacy and safety of postoperative early mobilization for chronic subdural hematoma in elderly patients.

Background: The incidences of chronic subdural hematoma (CSDH) will probably increase with the aging of the population; thus, postoperative care of elderly CSDH patients may play a more important role in surgical management. The aim of this study was to evaluate the efficacy of and adverse effects after postoperative early mobilization (EM) for elderly CSDH patients.

Methods: This is a single-institution historical control study.

Bilateral medial medullary infarction due to bilateral vertebral artery dissection.

We describe a 52-year-old woman who experienced transient motor weakness and numbness of the left extremities and presented 2 days later with severe hemiparesis and sensory impairment of the right extremities and right lingual palsy. Magnetic resonance imaging (MRI) revealed bilateral upper medial medullary infarction, primarily in the left ventral portion. The findings of both three-dimensional (3D) computed tomographic and conventional angiography suggested dissection of both intracranial vertebral arteries (VAs).

Unilateral oculomotor nerve paresis associated with anterior communicating artery aneurysm rupture--two case reports.

Two cases of complete unilateral oculomotor nerve palsy occurred after subarachnoid hemorrhage (SAH) due to a ruptured anterior communicating artery aneurysm. A 61-year-old female suffered left oculomotor nerve paresis after mild SAH. This paresis was probably related to pre-existing oculomotor nerve stretching caused by abnormal positioning of the posterior cerebral and superior cerebellar arteries in the premesencephalic cistern.

[Ruptured frontopolar artery aneurysm: two cases].

We report two very rare cases of subarachnoid hemorrhage due to a ruptured frontopolar artery aneurysm in the cingulate sulcus. Only two surgically treated cases have been reported. Case 1: A 69-year-old woman suffered headache and was admitted to our hospital the next day.

[Shotgun injury of head and neck: case report].

A 48-year-old male was hit by a shotgun blast from behind while he was hunting. He was only 7 meters away when one of his colleagues pulled the trigger accidentally. About 180 lead pellets penetrated his head and neck.
