A Case of Growing Chronic Subdural Hematoma with Niveau Formation Showing an Enhanced Subdural Hyperintense Band on Magnetic Resonance Diffusion-Weighted Imaging Over Time.

This case report describes an 84-year-old female patient with a growing chronic subdural hematoma (CSDH) that showed an enhanced subdural hyperintense band on magnetic resonance diffusion-weighted imaging over time, indicating that it reflects fresh bleeding from the outer membrane covering the hematoma. The presence of subdural hyperintense band on magnetic resonance diffusion-weighted imaging of CSDH, possibly reflecting hemorrhagic diathesis of the outer membrane, might be a predictor of enlargement of CSDH.

Acute subdural hematoma requiring surgery in the subacute or chronic stage.

The aim of this study was to clarify the clinical characteristics and pathophysiology of conservatively treated cases of acute subdural hematoma (ASDH) that ultimately require surgery in the subacute or chronic stage, and devise an appropriate form of management for them. A total of 50 patients with ASDH were admitted to our institution during a 5-year period. Hematoma removal in the subacute or chronic stage was performed in 8 patients.

Epidemiology of subarachnoid hemorrhage in the Yaeyama Islands, an isolated subtropical region of Japan most frequently affected by typhoons: a population-based study.

Objective: The present study analyzed epidemiological data for patients with subarachnoid hemorrhage (SAH) in a subtropical region of Japan that is the most frequently affected by typhoons.

Patients And Methods: The medical records of hospitalized patients who had been diagnosed as having SAH at Okinawa Prefectural Yaeyama Hospital during a 13-year period were reviewed. Demographic and epidemiological data including date and time of onset and activity at onset and clinical data were collected.

[Aneurysmal subarachnoid hemorrhage in the Yaeyama Islands, Japan, from 1989 to 2002].

The aim of this study was to analyze epidemiological and clinical data of patients with aneurysmal subarachnoid hemorrhage (SAH) in the Yaeyama islands, an isolated subtropical region of Japan. A total of 94 patients (31 men and 63 women, mean age 57.3 years) were diagnosed as having non-traumatic SAH during a 13-year period from 1989 to 2002.

Recurrence and extension of lobar hemorrhage related to cerebral amyloid angiopathy: multivariate analysis of clinical risk factors.

Background: Many recent studies have analyzed clinical risk factors for the recurrence and extension of intracerebral hemorrhage. However, they have not been investigated in patients with lobar hemorrhage related to cerebral amyloid angiopathy (CAA).

Methods: We studied 40 surgically treated patients with lobar hemorrhage diagnosed histologically as being related to CAA.
