germinoma/edema

Hypoxemia is a nearly constant accompaniment of head injury. Diverse theories have been proposed to explain this relationship. The authors report the case of a patient who suffered an episode of severe, transient, arterial oxygen desaturation during "controlled" brain trauma: an otherwise uneventful

UNASSIGNED To describe a unilateral ocular paraneoplastic syndrome in pineal germinoma. UNASSIGNED A 24-year-old male presented with diplopia, excessive thirst, and frequent urination. Cranial MRI showed a mass in pineal gland. Dorsal midbrain syndrome signs were present. Examination showed optic

Cerebrospinal fluid (CSF) edema and porencephaly are rare postoperative complications of a ventricular shunt that result from obstruction of the distal catheter, especially in children with taut ventricles. We report a 10-year-old male with cerebellar germinoma complicated by obstructive

A 25-year-old man presented with headache and consciousness disturbance. MRI revealed well enhanced mass lesions using gadolinium at bilateral thalamus and right para lateral ventricle with mild perifocal edema. Obstructive hydrocephalus was observed. On neuroendoscopic observation, the tumor was

OBJECTIVE Germinomas originating from the basal ganglia (BG) are rare. Early diagnosis is important for favorable prognosis, but it is difficult due to the slow clinical course and subtle changes on neuroimaging. The purpose of this study was to evaluate the usefulness of susceptibility-weighted

METHODS Case report. OBJECTIVE We present for the first time a patient with multifocal intramedullary cervical spinal cord germ cell tumors with elevated serum alpha-fetoprotein (AFP). METHODS Nanjing Drum Tower Hospital, The Affiliated Hospital of Nanjing University Medical School, Nanjing,

Intracranial germ cell tumors are a rare group of neoplasms constituting 1% to 2% of primary intracranial tumors in North America and Europe. Germinomas of the corpus callosum are exceedingly rare, accounting for only 0.7% of all intracranial germ cell tumors. We report a case of germinoma in the

BACKGROUND Germinomas are sensitive to radiation therapy and chemotherapy; therefore, correct imaging diagnosis is crucial for them. However, the imaging findings of germinomas originating from off-midline regions displayed different patterns from those originating from midline areas. UNASSIGNED 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.

Patients who have a pineal germinoma usually present with symptoms of intracranial hypertension or disturbances in vertical ocular motion but rarely present with amnesia. We recently encountered a case of pineal germinoma accompanied by severe amnesia, but not by hydrocephalus. A 32-year-old,

OBJECTIVE To investigate the value of magnetic resonance imaging (MRI) in the diagnosis of intracranial germinoma. METHODS A retrospective analysis of the MRI features was conducted in 19 cases of pathologically confirmed intracranial germinoma. RESULTS The lesion was located in the sellar region in

We report a patient with a germinoma originating in the left basal ganglia. Unenhanced computed tomography (CT) revealed a relatively well-defined high-density lesion, which was slightly enhanced with contrast medium. No tumor stain was noted on angiography. The mass showed hypointensity on

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

A case of primary intracranial germinoma in the left basal ganglia treated with interstitial brachytherapy was reported. A 15-year-old boy was referred to our hospital for evaluation of right hemiparesis. A CT scan showed a slightly hyperdense mass with multiple cystic low density in the left basal

OBJECTIVE The purpose of this study was to describe the MR imaging appearance of germinomas in the basal ganglia and thalamus and to compare the MR findings with CT findings. METHODS Eleven MR studies of 10 patients with pathologically proved germinomas in the basal ganglia or thalamus were
