A case is presented in which bilateral, isodense subdural hematomas, not readily apparent on immediate rapid-high-dose computed tomography, became enhanced and clearly visible on delayed scans. If difficulty is encountered in interpreting the immediate scan of a patient suspected of having isodense subdural ...

Subdural haemorrhages (SDH) are associated with significant neurodisability in affected individuals. The incidence of SDH in infants is between 12 and 25 cases per 100,000 children and most detected SDH are due to physical abuse. In the infant brain, SDH are caused by tearing of the bridging veins in the subdural space and may result in significant brain ...

The ability of magnetic resonance (MR) to identify intracranial hematomas was tested in five patients with clinical and computed tomographic signs of chronic subdural hematoma. The extracerebral collections were displayed as a zone of bright intensity using the T1-weighted inversion recovery (IR 1500/400) sequence, reflecting the lesions' short T1 relaxation times. ...

Magnetic resonance (MR) images and computed tomograms of 25 patients with head trauma were compared. MR proved to be superior in many ways for demonstrating extracerebral as well as intracerebral traumatic lesions. Isodense subdural hemotomas, which present a diagnostic dilemma on CT images were clearly seen on MR, regardless of their varying CT densities. ...

ObjectiveChronic subdural hematomas (CSDH) are more common on the left hemisphere than on the right. We verified this left predilection of CSDH and tried to explain the reason for this discrepancy.MethodsWe investigated the laterality of CSDH in 182 patients who were treated from January 2005 to December 2009. We examined the symmetry of the cranium and the location of the ...

Subdural empyema of the brain is an uncommon disorder that occurs more frequently in children than in adult. Authors report a very rare of subdural empyema following the subdural hygroma after mild head injury. The exact mechanism of infection is not known. However, we have to consider subdural infection as one of ...

A personal identification system based on isodensity maps in which the properties of a face is well reflected has been proposed. In the conventional method, however, there were problems in terms of memory requirements for registration of facial images and the processing time. To improve these problems, a new matching scheme using chain coded isodensity ...

The authors report the case of a 56-year-old previously healthy man who presented with a 4-month history of postural headache accompanied by nausea and vomiting. The results of initial imaging studies of the brain were normal. Repeated MR imaging demonstrated bilateral subdural hematomas which were drained and reaccumulated over a period of time. Spinal ...

Child abuse by whiplash-shaking can lead to severe injury in infants, including cerebral damage, neurological defects, blindness, and mental retardation. These findings are seen often without external evidence of head injury. Nurses should suspect shaken baby syndrome (SBS) in infants less than 1 year of age who present with apnea, seizures, lethargy or drowsiness, bradycardia, respiratory ...

A 44-year-old man visited a nearby hospital because of severe headache. Brain MRI revealed a subdural hematoma, and he was transferred to the Department of Neurosurgery of our hospital. Burr hole surgery was performed on the second day of hospitalization because of an enlargement of the hematoma. Laboratory data on admission showed the presence of a disseminated intravascular ...

A case of chronic subdural haematoma in the posterior fossa, secondary to anticoagulant treatment, is presented. The unusual clinical presentation of vertigo and nystagmus and the atypical CT are discussed. This seems to be the first report to describe a chronic subdural haematoma in the posterior fossa in an alive adult.Images

Subdural hematoma is a serious but rare complication of spinal anesthesia. A 70-year-old woman patient underwent elective total knee replacement under spinal anesthesia. At 4 days postoperatively, the patient complained of headache and vomiting. Brain computed tomography revealed an acute-on-chronic subdural hematoma with midline shift. The patient ...

Only 30 cases of traumatic intracranial aneurysm (TICA) secondary to missile injury have been reported to date. To these we add 15 more cases. Missile TICAs are often seen on a secondary branch of the middle cerebral artery and are usually accompanied by a intracerebral hematoma (80%) or by an acute subdural hematoma (26%). Fourteen of our cases were ...

Traumatic brain injury (TBI) is often accompanied by additional trauma that can be obscured by cognitive dysfunction or multiple injuries in the same region of the body. This report describes the case of an unhelmeted motorcycle rider who collided with a telephone pole. He sustained a diffuse subarachnoid hemorrhage, bilateral subdural hematomas (right ...

CT fluoroscopy (CTF) facilitates guidance of percutaneous biopsies and other interventional procedures. We wished to demonstrate the usefulness of CTF for the puncture of an unenhanced isodense liver lesion during continuous injection of intravenous contrast medium. We performed CTF-guided puncture of a 2-cm lesion in the liver of a patient suffering from lung cancer. CTF ...

The area of isodensity contours in a smoothed density field can be measured by the contour-crossing statistic N1, the number of times per unit length that a line drawn through the density field pierces an isodensity contour. The contour-crossing statistic distinguishes between Gaussian and non-Gaussian fields and provides a measure of the effective slope ...

Background:Subdural posttraumatic collections are called usually Traumatic Subdural Hygroma (TSH). TSH is an accumulation of cerebrospinal fluid (CSF) in the subdural space after head injury. These collections have also been called Traumatic Subdural Effusion (TSE) or External Hydrocephalous (EHP) according to ...

Subdural empyema is a rare form of intracranial sepsis associated with high morbidity and mortality. The most frequent cause is extension of paranasal sinusitis through emissary veins or of mastoiditis through the mucosa, bone, and dura mater. Development of subdural empyema after pyogenic meningitis is known to be very unusual in adults. We report a rare ...

Subdural empyema is a known yet infrequent complication of bacterial meningitis. Subdural effusions occur frequently with meningitis in children and usually resolve spontaneously or with subdural taps. Subdural empyema should be suspected when a patient fails to respond to antibiotic therapy or worsens ...

Background. Subdural collections of cerebrospinal fluid (CSF) with associated hydrocephalus have been described by several different and sometimes inaccurate terms. It has been proposed that a subdural effusion with hydrocephalus (SDEH) can be treated effectively with a ventriculoperitoneal shunt (V-P shunt). In this study, we present our experience ...

Subdural empyema represents a loculated suppuration between the dura and the arachnoid. It has been described either intracranially or in the spinal canal, the latter localization being quite rare. It is a rare but serious illness with a declining mortality rate but rather frequent neurological sequelae. Morbidity and mortality in intracranial and spinal ...
