1/6. glioblastoma multiforme of the pineal region: case report.PURPOSE: pineal region tumors are uncommon, and comprise more frequently three categories: germ cell, parenchymal cell and glial tumors. Most pineal gliomas are low-grade astrocytomas. glioblastoma multiforme, the most aggressive and common brain tumor, is extremely rare at this location with only few cases reported. CASE DESCRIPTION: a 29-year-old woman with a two month history of headache, nuchal pain, fever, nausea and seizures and physical examination showing nuchal rigidity, generalized hypotony, hypotrophy and hyper-reflexia, Babinski sign and left VI cranial par palsy. CT scan examination revealed a ill-defined hypodense lesion at the pineal region with heterogeneous contrast enhancement. MRI showed a lesion at the pineal region infiltrating the right thalamic region. The patient underwent a right craniotomy with partial resection of the mass. The histological examination of paraffin-embedded material defined the diagnosis of glioblastoma multiforme. Post-operative radiotherapy was indicated but the patient refused the treatment and died two months afterwards. CONCLUSION: in spite of its rarity at this location, glioblastoma multiforme should be considered in the differential diagnosis of aggressive lesions at the pineal region.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/6. cafe-au-lait spots and early onset colorectal neoplasia: a variant of HNPCC?BACKGROUND: cafe-au-lait spots (CALS) are classically found in neurocutaneous syndromes such as neurofibromatosis, but have not been associated with hereditary colorectal cancer. However, review of hereditary colorectal cancer case reports reveals occasional description of CALS on physical exam. methods: We describe the colonic and extracolonic phenotype in a family with CALS and early onset colorectal neoplasia (adenomas and/or cancer) and review 23 additional families reported in the literature. RESULTS: Among the 24 families, 32/59 (54.2%) individuals had colorectal adenomas diagnosed at a mean age of 15.7 /- 1.1 (SE) years (range 5-38 years). The majority (24/32, 75.0%) of persons at first colorectal examination had oligopolyposis (< 100 polyps) versus polyposis (> or = 100 polyps). Forty-two of 59 (71.2%) individuals were affected with colorectal cancer, diagnosed at a mean age of 31.9 /- 2.7 years (range 5-70 years). A brain tumor was found in 28/59 (47.5%) affected individuals (4 families with 2 or more cases) with an overall mean age of diagnosis of 16.5 /- 1.2. lymphoma and/or leukemia was found in 8/24 (33.3%) families (one family with 3 cases). Two families had mutation of the mismatch repair gene, hPMS2 (1 with homozygous germline mutation), while two carried homozygous germline mutations of another mismatch repair gene, hMLH1. CONCLUSIONS: cafe-au-lait spots with early onset colorectal neoplasia may identify families with a variant of HNPCC characterized by oligopolyposis, glioblastoma at young age, and lymphoma. This variant may be caused by homozygous mutation of the mismatch repair genes, such as hPMS2 or hMLH1.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
3/6. Psychiatric symptoms and brain tumor.Psychiatric symptoms may be the only clue to the presence of a brain tumor. Careful physical, neurologic and psychiatric examinations will reveal the diagnosis. Affective and schizophrenia-like psychoses are related to dysfunctions of the right and left hemispheres, respectively. Lesions of the temporal lobes commonly cause depression. Psychotropic medications may improve symptoms in the presence of tumor. There is no clinical method of localizing or excluding a brain tumor by its psychiatric manifestations.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
4/6. glioblastoma multiforme.glioblastoma multiforme is the most common primary brain tumor of adults, as well as the most malignant. Its etiology is unknown, but the tumor is thought to arise through dedifferentiation of adult astrocytes. It occurs most frequently between the ages of 40 and 60, in men more often than in women (1.5:1). Important early symptoms include subtle personality change, headache, weakness, and intellectual impairment; specific complaints and physical findings depend on the location of the lesion. The initial diagnostic test should be a CT-scan; it will detect more than 90% of malignant astrocytomas. Surgery remains the cornerstone of treatment; patients receiving radical debulking have a median survival of 8 months compared to the 3 month survival of unoperated cases. Modern neurosurgical technique, neuroanesthesia, mannitol, and corticosteroids have reduced the surgical mortality to 3%. Most patients also receive 4500 rads of whole-brain irradiation and 1800 rads to the operative site; radiotherapy increases the median survival of operated patients by 2 to 3 months. An additional small increment in survival time and some improvement in quality of survival can be achieved by nitrosourea chemotherapy; the latter is usually given as 100 mg/m2/day x 3 days of BCNU every eight to ten weeks. Experimental treatments under study include the use of radiosensitizers, the role of immunotherapy and the application of microwave-induced hyperthermia. Two-year survival remains 10% to 20%, and there are virtually no five-year survivors. An optimal combined modality treatment plan, one in which each cellular compartment of this truly multiforme tumor is effectively addressed, remains to be designated.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
5/6. anxiety and depression in elderly patients receiving treatment for cerebral tumours.Little is known regarding affect and the quality of life of elderly persons with malignant brain tumours. More elderly patients are currently being diagnosed with primary malignant CNS tumours and current, aggressive treatment has extended median life expectancy. This case study indicated significant levels of clinical depression and anxiety may be experienced. Additionally, trait anxiety was found to increase with tumour progression. The patient's concern regarding loss of conjugal closeness and social inactivity was identified for the first time in persons with malignant brain tumours. Being progressively less active physically, and more isolated emotionally, this patient used her relatively good general intellectual abilities to worry about her situation. At the present time integration into the community and distress over her ability to be assertive decreased. Practical barriers to the delivery of psychological services were encountered and are likely to have been under appreciated.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
6/6. Fetal glioblastoma: rapid growth during the third trimester.We present a case of fetal glioblastoma which appeared after 28 weeks' gestation. The first ultrasonographic finding was an enlarged fetal head with right shifted falx cerebri at 31 weeks' gestation. At 33 weeks, a large and high echogenic mass in the left hemisphere and right enlarged ventricle was identified. magnetic resonance imaging showed that the tumor was localized in the left hemisphere and a margin of the tumor was defined. Because fetal well-being judging from biophysical parameters was good and we considered that the tumor was resectable, a male fetus weighing 2,670 g was delivered at 34 weeks' gestation by cesarean section. However, he was inoperable due to consumptive coagulopathy and rapid growth of the tumor, and died on the 41st day of life.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
