craniopharyngioma/edema

OBJECTIVE The pattern of edema caused by craniopharyngiomas and other common suprasellar masses could be useful for determining the differential diagnosis of lesions in this region. The purpose of this study was to ascertain whether the pattern of edema spread on MR images can be used in the

Two patients with craniopharyngioma presenting with the "optic tract edema sign" are described. This sign is seen in a majority of craniopharyngiomas and can be of help in the differentiation with other suprasellar masses such as pituitary adenomas, meningiomas, germinomas and lymphomas.

This report describes two cases of craniopharyngioma with perifocal edema. In both patients, computed tomography and magnetic resonance imaging (MRI) revealed that the tumors occupied the suprasellar cistern, invaginated the floor of the 3rd ventricle and were tightly adherent to the ventricular

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

OBJECTIVE The Wnt/β-catenin signaling pathway is strongly implicated in the pathogenesis of adamantinomatous craniopharyngioma (adaCP). However, there is no evidence that the CTNNB1 mutation activates the target gene of Wnt/β-catenin signaling, and it is unknown whether it affects the tumorigenesis

We report an 80-year-old woman who was admitted to our hospital with symptoms due to diabetes insipidus. Magnetic resonance (MR) imaging demonstrated a sellar/suprasellar cystic lesion with marginal enhancement and the thick pituitary stalk. The MR imaging depicted edema spreading along the optic

Intracystic bleomycin therapy has been proposed as a treatment for predominantly cystic craniopharyngioma. The risks of using this therapy, however, have not been clearly identified. The authors report on three children treated with intracystic bleomycin who developed initially mild symptoms during

OBJECTIVE We present the case of a patient treated for intracranial germ cell tumor in which elements of craniopharyngioma were found in the residual tumor mass. RESULTS A 17 year old patient presented with a history of secondary amenorrhea. She deteriorated with headache and left eyelid drop,

The results of ophthalmologic examinations of 50 children with craniopharyngiomas are analyzed. The condition was diagnosed on the basis of clinical examinations, roentgenography, angiography, brain scintigraphy, and computer-aided tomography. In 48 cases the diagnosis was confirmed by histologic

OBJECTIVE Edema-like change along the optic tract commonly occurs in association with craniopharyngiomas. The aim of this study was to clarify whether it occurs in association with other common pituitary region tumors and to elucidate its mechanism as seen on MR images. METHODS Fifty patients with

Quality of life of craniopharyngioma patients can be severely impaired by derangement of hypothalamic function. A classification, taking into account preoperative hypothalamic damage, evaluated by magnetic resonance imaging (MRI), and correlating it with postoperative weight change is still missing

Radiation therapy is widely used as adjuvant or primary treatment modality of neoplastic lesions. Radiation therapy may cause an acute adverse effect such as brain edema, radiation necrosis, or delayed, for example, panhypopituitarism, vasculitis, and rare de-novo neoplasm development. However,

A rare case in presented of a patient with edema formation along the optic pathway, which was caused by metastatic suprasellar tumor mimicking craniopharyngioma. A 63-year-old female with visual disturbance, diabetes insipidus, and symptomatic panhypopituitarism was admitted to our hospital. CT
