A 52 year old man with Creutzfeldt-Jakob disease who received a cadaveric dura mater graft 99 months before the onset is reported. The prion protein gene was homozygous for methionine at the polymorphic codon 129. Neuropathological examination disclosed a panencephalopathic type of Creutzfeldt-Jakob disease which was characterised by severe involvement of the cerebral white matter and cerebellu...
Spinal extradural arachnoid cyst (SEDAC) is a cyst in the spinal canal that protrudes into the epidural space from a defect in the dura mater and leads to neurological disturbances. We previously showed that familial SEDAC is caused by FOXC2 mutation; however, the causal gene of sporadic SEDAC has not been identified. To identify the causal gene of sporadic SEDAC, we performed whole exome seque...
The lumbar epidural region was studied using computerized tomography. This technique allows examination of the region in vivo. It confirmed that the spinal canal is oval in the upper lumbar region, becoming triangular lower down, and that the ligamenta flava form a posterior recess to the vertebral canal. Epidural fat is confined to this region between the ligamenta flava and the intervertebral...
Haemostatic and isolating materials may cause local reactions as a foreign body. The case presented here of intracranial granulomatous lesion pertains to a patient operated in two stages due to a huge meningioma. During the first operation the tumour was partially removed. Because of persistent intraoperative haemorrhage haemostatic flakes of Oxycel and Spongostan were applied locally. In order...
Hypertrophic pachymeningitis is an uncommon disorder that causes a localized or diffuse thickening of the dura mater. Recently, the possibility that IgG4-related sclerosing disease may underlie some cases of intracranial hypertrophic pachymeningitis has been suggested. We herein report the tenth case of IgG4-related intracranial hypertrophic pachymeningitis and review the previous literature. A...
During the last seven decades many materials have been experimentally tried as dural substitutes, and many have been discarded after being clinically introduced. In recent years, satisfactory results from Orlan (Huertas, 1955), Vinyon 'N' (Teng and Feigin, 1955; Teng, 1961), and homologous dura mater (Crawford, 1957; Campbell, Bassett, and Robertson, 1958) as dural substitutes have been reporte...
OBJECTIVE To report the association of temporal arteritis and enhancement of the dura mater and temporalis muscle. DESIGN AND METHODS A single patient with a complaint of headache and diplopia was studied. SETTING Academic medical center. PATIENT A 69-year-old man presented with lateral rectus weakness, temporal artery tenderness, and an erythrocyte sedimentation rate of 65 mm/h. INTERV...
A 41-year-old woman with a complex congenital nevus that possessed features of both a blue nevus and a nevus of Ota is described. She was found to have melanotic hyperpigmentation of the underlying subcutaneous tissue and dura mater. Two separate melanomas developed in the tissues underlying her nevus (one in the subcutaneous tissue and another intracranially, arising from the dura).
The objective of this study was to examine the clinical findings, magnetic resonance imaging (MRI), pathological features, and treatment experiments of patients with hypertrophic cranial pachymeningitis (HCP). The clinical findings, MRI, and pathological appearances of 9 patients with HCP were analyzed retrospectively. The thickened dura mater was markedly enhanced after contrast media injectio...
We introduce a 15 cm, 26-gauge spinal needle (Steriseal Ltd, Redditch) through a standard Tuohy needle (9·6 cm, 16-gauge) which has its tip in the epidural space. Once the dura has been punctured the spinal needle is only really held in place by the dura. It is therefore quite difficult to attach the syringe of local anaesthetic and then inject without inadvertently placing the tip of the spina...
