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)
PURPOSE To describe the gadolinium-enhanced MR findings of Rathke cleft cyst correlate them with the surgical findings, and define those preoperative findings that differentiate this lesion from other sellar and juxtasellar tumors. METHODS We studied 18 patients who were diagnosed as having Rathke cleft cyst pathologically. These patients were imaged with(More)
BACKGROUND Spontaneous disappearance of an arachnoid cyst is very rare, particularly after suppurative meningitis. CASE REPORT A 2-month-old boy with a high fever was diagnosed with suppurative meningitis by cerebrospinal fluid examination. Computed tomography disclosed a large arachnoid cyst in the left middle cranial fossa. Two months later, the(More)
The incidence of intracranial 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)
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)
There is continuing controversy about the benefits of decompressive craniectomy for the treatment of massive infarction of middle cerebral artery (MCA) territory. Under conservative therapy, the mortality rate for this stroke is reported to be up to 80%. So the authors have actively carried out decompressive craniectomy since 1997, and have compared the(More)
OBJECT The purpose of this study was to evaluate the accuracy of multidetector-row CT angiography (MDCTA) in demonstrating spinal dural arteriovenous fistulas (SDAVFs). METHODS The authors studied 10 patients with SDAVFs, including 2 with spinal epidural AVFs, who underwent preoperative MR imaging, MDCTA, and digital subtraction angiography (DSA). In the(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)
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)
