Arachnoid cysts are benign congenital lesions of the central nervous system accounting for 1% of all intracranial masses. Intraventricular location of arachnoid cyst especially in the fourth ventricle is rare. Fenestration or marsupialization of these "innocent-looking" benign cysts can lead to
Background: Fibrous dysplasia (FD) is a rare disorder of expansile fibro-osseous lesions that may be associated with extraskeletal features as part of McCune-Albright syndrome (MAS). Optic disc edema is a potentially serious
Electroconvulsive therapy (ECT) is often considered relatively contraindicated in patients with intracranial space-occupying lesions, especially those with increased intracranial pressure, edema, or mass effect. We describe the safe use of ECT in 6 patients with arachnoid cysts. We conclude that
The authors report a case of a hemorrhage of the brainstem after craniotomy for resection of a huge arachnoid cyst of the sylvian fissure on the left hemisphere. The previous simptomatology included clinical signs of increased intracranial pressure, and the computerized tomography showed midline
Cerebral arachnoid cysts that eroded the skull base and extended into the paranasal sinus are very rare with only a few cases reported.
A 71-year-old woman with history of headache for 4 years was evaluated because of an enlarging right temporal cystic lesion with evidence of resorption of the
The results of a prospective study on excision of the outer and inner membrane for symptomatic primary middle fossa arachnoid cysts in children are presented. During the period 1982-1989, among 48 cases of cyst in various locations, 18 symptomatic patients were treated by excision of both the outer
We report the case of a 57-year-old man who was admitted on the basis of worsening paraplegia and incontinence. This patient had developed similar neurologic symptoms 15 previously but fully recovered after conservative medical therapy with corticosteroids. At that point, he was diagnosed with a
OBJECTIVE
To clarify the accuracy, sensitivity, and specificity of optic tract edema in the diagnosis of craniopharyngiomas.
METHODS
Preoperative magnetic resonance images (MRIs) of 49 patients (between May 1996 and March 2003) who had a diagnosis of parasellar masses were blindly reviewed by two
The author describes 2 cases of children with growing skull fractures (GSFs). Surgical exploration of the widened fracture shortly after the head injury failed to reveal a dural tear because the neuroimaging studies (MR images, CT scans, and skull radiographs) had not been accurately interpreted,
We present the case of a male infant born at 37 weeks gestation with multiple congenital anomalies, including hydrops fetalis, facial and visceral abnormalities, short ribs, and short limbs without polydactyly. We believe that this represents a further case of the Beemer-Langer syndrome, a
Spinal arachnoiditis (SA) is an extremely rare and delayed complication of subarachnoid hemorrhage (SAH). Little is known about its underlying pathogenesis and subsequent clinical course. A middle-aged patient presented with the worst headache of her life and a grade 3 SAH of the basal-cisterns and
This work makes proposals on the relationship between intracranial pressure (ICP) and hydrocephalus that changes over time with the evolution of the disease. This includes the cerebrospinal fluid (CSF) filling mechanism that leads to an increase in mode pressure if excess fluid volume exacerbates
Our objective was to evaluate the diagnostic and prognostic value of sonography hypoechoic lesions. A retrospective study revealed revealed a total of 21 cases diagnosed over a period of 10 years. Most of the diagnosis were made in the third trimester. The presence fluid-filled lesions within the
Seven adults with Listeria monocytogenes infection of the central nervous system had computed X-ray tomography of the head performed. One patient had a normal scan, three had hydrocephalus; cerebral edema, an arachnoid cyst and hyperemia were each noted in one patient. Atrophy of the vermis of the
In this retrospective cohort study, a clinical and administrative database of children hospitalized at Primary Children's Medical Center, Salt Lake City, Utah, between January 1, 2002, and December 31, 2006, was used to identify those with laboratory-confirmed rotavirus infections and at least one
