a set of one hundred and twenty nine patients with known primary malignancy and suspected brain metastasis was reviewed in present study. the patients were selected among patients presented to the mri section of imam khomeini hospital or a private mri center in tabriz (iran). primary tumor site, clinical manifestations, number and site of lesions were identified in this patient population. the ...

A patient presenting an unusual clinical picture was recently admitted to the New Haven Hospital. She showed definite objective evidence of involvement of the central nervous system, but other obscure signs present made an accurate diagnosis difficult. At necropsy a most unexpected lesion was found involving the base of the brain, the nerve roots, and the spinal cord. The case is of particular ...

purpose: to record the mri features of primary central nervous system lymphoma (pcnsl) and compare these properties in monofocal and multifocal disease. methods: eleven cases of monofocal disease were compared to 9 cases of multifocal disease. all patients were examined by non-enhanced and contrast-enhanced mri. tumor location, signal intensity, enhancement characteristics, age distribution, pe...

the incidence of brain neoplasm has been progressively increasing in recent years in the industrialized countries. one of the reasons for this increased incidence could be better access to health care and improved diagnosis in the industrialized countries. it also appears that caucasians have a higher incidence than blacks or hispanics or asians. a number of risk factors have been identified an...

  Abstract: Gestational Trophoblastic Neoplasm (GTN) is among rare human tumors which can be observed with widespread metastasis. Two young patients with emergent neurologic symptoms with no gynecological problems are presented in this report. GTN was later diagnosed in both cases with brain metastasis. The first case: A 22 years old patient, admitted to the infectious disease ward, with probab...

A decline of mortality dependence on age from the exponential relation is observed for some diseases. This decline could be explained by the existence of an inherently susceptible population subset which is depleted faster than the general population. A model is presented which describes this situation using malignant neoplasm of the brain. The model assumes that only those who are members of t...

Pancreatic neoplasm is represented by the subtype Adenocarcinoma in 90% to 95% of cases, characterized high lethality rate its presentations; however, cases progression brain site are manifested only 0.1% 0.3% all cases. The present study aims report a rare case patient undergoing treatment for pancreatic cancer, which had median overall survival significantly higher than time related such neop...

colloid cysts are mucous-filled masses with an outer fibrous layer. these cysts are rare developmental malformation and not a true neoplasm. they usually found incidentally and are asymptomatic; but in some cases may associate with rapid neurologic deterioration, herniation, and sudden death. recognition of this rare but important diagnosis may result in decreasing mortality. in this report, we...
