UNLABELLED Previous studies of samples from cranial meninges have created doubts about the existence of a virtual subdural space. We examined the ultrastructure of spinal meninges from three human cadavers immediately after death to see whether there is a virtual subdural space at this level. The arachnoid mater had two portions: a compact laminar portion covering the dural sac internal surface...

Mortality and morbidity rates are high among children with acute bacterial meningitis, especially in young ages. A im: to determine the most common neurologic complications during the acute phase of childhood bacterial meningitis and long term sequelae. Material and methods: A total of 277 children (aged 0-16years) were evaluated for acute neurologic complications following bacterial meningitis...

BACKGROUND AND OBJECTIVES Subdural hematoma is a known complication of long-term hemodialysis. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS The US Renal Data System was used to determine the occurrence rate of nontraumatic subdural hematoma in long-term dialysis patients and to evaluate time trends. RESULTS The occurrence rate of subdural hematoma in long-term dialysis patients is 10 tim...

Subdural empyema is a rare but serious intracranial infection that warrants prompt management to reduce morbidity and avoid mortality. However, clinical and radiologic features may be subtle or ambivalent. Thus a diagnosis of subdural empyema should not be discounted, especially in a patient with a history of head trauma. Treatment consists of surgery to establish bacteriologic identification a...

OBJECTIVES Although there is general agreement that surgery is the best treatment for chronic subdural haematoma (CSDH), the extent of the surgical intervention is not well defined. METHODS The less invasive surgical technique of bedside percutaneous subdural tapping and spontaneous haematoma efflux after twist drill craniostomy under local anaesthesia was prospectively analysed in 118 adult ...

Chronic subdural hematomas (CSHs) are generally regarded to be a traumatic lesion. It was regarded as a stroke in 17th century, an inflammatory disease in 19th century. From 20th century, it became a traumatic lesion. CSH frequently occur after a trauma, however, it cannot occur when there is no enough subdural space even after a severe head injury. CSH may occur without trauma, when there is s...

Objective Chronic subdural hematoma is a common and relatively benign disease. However, recurrence is common after surgical treatment, and the recurrence rate varies from 5% to 33%. The aim of this study was to investigate the predictive factors for recurrence of chronic subdural hematoma. Methods We analyzed data from 248 patients with chronic subdural hematoma who were treated by burr-hole ...

MR images of 24 patients with 33 subdural collections were retrospectively reviewed to determine the spectrum of MR findings associated with such lesions. The lesions were dated by history, when available. Hematomas were grouped as follows: acute, four; early subacute, four; late subacute, four; chronic, 13. Six collections were classified as rehemorrhage; and two patients had CSF hygromas. Sub...

Chronic subdural hematoma (CSDH) and symptomatic subdural hygroma are common diseases that require neurosurgical management. Burr hole trephination is the most popular surgical treatment for CSDH and subdural hygroma because of a low recurrence rate and low morbidity compared with craniotomy with membranectomy, and twist-drill craniotomy. Many reports suggest that placing a catheter in the subd...

Dural metastasis (pachimeningeal carcinomatosis) refers to involvement of dura mater and subdural or epidural spaces in systemic cancer. Although dural metastasis are relatively frequent in malignancies, (8-9% of patients with advanced systemic cancer in autopsy), they are rarely associated with subdural hematoma. We present the case of a 66-year-old male, refereed to the hematological unit for...
