OBJECT The vertebral artery (VA) often takes a protrusive course posterolaterally over the posterior arch of the atlas. In this study, the authors attempted to quantify this posterolateral protrusion of the VA. METHODS Three-dimensional CT angiography images obtained for various cranial or cervical diseases in 140 patients were reviewed and evaluated.(More)
The syndrome of the sinking skin flap (SSSF) has been described as one of the causes of neurological deficits after decompressive craniectomy We report a case of a 57-year-old woman with SSSF. Two years earlier, this patient, with no neurological deficits, underwent removal of the bone flap during treatment of an epidural abscess due to wound infection(More)
The incidence of in tracranial aneurysm associated with pituitary adenoma is not definitely established although reported higher than in general population. This study was designed to find the existence of such association in a large series of pituitary adenoma cases. A retrospective study of 467 cases of pituitary adenoma (mean age: 41 ± 15 years) was(More)
OBJECT The increase in the incidental detection of asymptomatic pituitary adenomas, known as "pituitary incidentalomas," led the authors to conduct a survey of the natural course of these lesions. METHODS Forty-two patients with clinically nonfunctioning pituitary adenomas who had manifested no neurological or endocrinological disorders were monitored(More)
BACKGROUND Preoperative differential diagnosis of interhemispheric cysts is sometimes difficult. CASE DESCRIPTION We recently experienced a case of symptomatic interhemispheric arachnoid cyst in a 62-year-old woman. We reviewed interhemispheric arachnoid cysts in the elderly and the management of symptomatic interhemispheric arachnoid cysts in elderly(More)
Interstitial deletions involving the chromosomal band 15q15 are very rare. A total of five cases were previously reported. Here another case of a 15q15.2-q22.2 deletion is reported, presenting with severe craniosynostosis of coronary, metopic, and sagittal sutures. The chromosome 15 with the 17.7-Mb deletion was of the paternal origin. A critical region for(More)
Two boys aged 8 and 12 years presented with intracranial germinoma manifesting as cerebral hemispheric atrophy, hemiparesis, and decline in academic performance. First magnetic resonance (MR) imaging showed no enhanced lesions, but follow-up MR imaging obtained 12 or 23 months after the first visit showed new mass lesions in the temporal lobe or pituitary(More)
Churg-Strauss syndrome (CSS) represents a rare systemic vasculitis that is almost invariably accompanied by bronchial asthma and eosinophilia. We report a case of a 36-year-old woman with previously diagnosed CSS presented with subarachnoid hemorrhage (SAH) from dissecting aneurysm in a vertebral artery (VA). Two months before onset of SAH, the patient had(More)
OBJECT Rathke cleft cysts (RCCs) are composed of tall, well-differentiated, ciliated columnar epithelia. Their structures are altered by hyperplasia or squamous metaplasia, but their cause remains unknown. METHODS The authors studied pathological findings and anterior pituitary function in 20 patients harboring RCCs. They classified RCC epithelium as(More)
The role of multi-detector-row computed tomographic angiography (MDCTA) in spinal vascular malformations has not yet been determined. We present a report on a short series of spinal arteriovenous fistulae (AVF) evaluated by MDCTA. With 4-row and 16-row MDCTA, three cases of spinal dural AVF and one case of perimedullary AVF were examined. Each case was also(More)
