1/183. Bone agent localization in hepatic metastases.We present the bone scintigrams of two patients, which demonstrate diffuse extraosseous uptake of a bone agent in metastatic masses in the liver, one from a primary lung tumor and one from a primary breast tumor. The bone imaging agent did not localize in the brain metastases in these patients. CTs of the abdomen in both patients showed massive metastases in the liver with multiple areas of tumor necrosis. The CT of the abdomen of the breast cancer patient showed multiple small hepatic calcifications. autopsy revealed massive tumor necrosis with calcifications in the enlarged liver. In routine bone scintigraphy, diffuse uptake of bone agents in the liver of a patient with a known malignancy should be considered suggestive of massive hepatic metastases.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
2/183. A leptomeningeal metastasis revealed by sciatica.Meningeal metastatic disease usually occurs as a complication of a brain tumor and is exceptionally isolated in patients with solid tumors. We report the case of a 74-year-old woman admitted for mechanical S1 sciatica refractory to drug therapy. She had been treated for breast cancer three years earlier. Physical findings were pain upon hyperextension of the lumbar spine and absence of the ankle jerks. Analysis of cerebrospinal fluid sampled during an intrathecal glucocorticoid injection showed 1 g/L of protein and 11 normal cells per mm3. Grade 3 L5-S1 spondylolisthesis was seen on plain radiographs, computed tomography scans, and magnetic resonance imaging scans. At that point, the patient developed sphincter dysfunction and motor loss in the left lower limb in the distribution of several nerve roots. Findings were normal from a myelogram and a magnetic resonance imaging study of the brain. A repeat cerebrospinal fluid analysis showed 1.1 g/L of protein and 5 cells/mm3. Because of the discrepancy between the clinical and imaging study findings, the patient was transferred to a neurology department. A third cerebrospinal fluid study showed numerous adenocarcinoma cells, and a repeat magnetic resonance imaging demonstrated a mass in the dural sac opposite L2. A program of monthly intrathecal methotrexate injections was started. A fatal meningeal relapse occurred eight months later. CONCLUSION: This case shows that a leptomeningeal metastasis can cause isolated nerve root pain, and demonstrates the diagnostic value of magnetic resonance imaging and cerebrospinal fluid cytology in patients with atypical symptoms, particularly when there is a history of malignant disease.- - - - - - - - - - ranking = 2keywords = brain (Clic here for more details about this article) |
3/183. cytomegalovirus pneumonia in a patient with breast cancer on chemotherapy: case report and review of the literature.cytomegalovirus (CMV) pneumonia in the setting of non-transplantation patients is a rarity. We present a case of CMV pneumonitis in a woman with stage IV breast cancer, with brain metastases, receiving both chemotherapy and systemic corticosteroids. A review of the literature reveals this as a unique case. Potential viral etiologies should therefore be considered in cancer patients with pneumonia receiving non-transplantation chemotherapy-regimens, particularly if steroids are a component of their therapy.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
4/183. Spinal epidural abscess complicating chronic epidural analgesia in 11 cancer patients: clinical findings and magnetic resonance imaging.We reviewed the records of all patients who had received an epidural catheter for management of chronic cancer pain in a 3-year period (1993-1996). patients with nervous system infections were identified, and pertinent clinical, radiological (magnetic resonance imaging), and bacteriological data were analyzed. We identified 11 patients who developed spinal epidural abscess (SEA). All of these had back pain; radicular signs occurred in seven patients and spinal cord compression in two patients. magnetic resonance imaging revealed SEA in all 11 patients. SEA was iso- to hypointense on T1-weighted images and hyperintense on T2-weighted images relative to spinal cord. After gadolinium administration seven lesions showed characteristic rim enhancement while three showed minimal enhancement. No signs of diskitis or osteomyelitis were present, and the abscess was always localized to the posterior epidural space. Cultures were positive in all cases and revealed staphylococcus epidermidis in eight and S. aureus in three. All patients were treated with intravenous antibiotics, and four had an additional decompressive laminectomy. Two patients died within 1 week of diagnosis from overwhelming septicemia despite apparently adequate antibiotic treatment. Within 4 weeks after diagnosis of SEA two patients died from widely metastatic disease, although infection may have contributed. One patient developed septicemia while receiving appropriate antibiotics and underwent emergency laminectomy. The neurological deficits recovered in all patients who survived the acute infectious episode. We conclude that patients with chronic epidural catheters for cancer pain require prompt neurological evaluation and magnetic resonance imaging when SEA is suspected. Early evaluation and treatment may lead to full recovery.- - - - - - - - - - ranking = 0.40340201597823keywords = nervous system (Clic here for more details about this article) |
5/183. Three cases of malignant lymphoma of the breast.We report three cases of malignant lymphoma (ML) of the breast and discuss diagnosis and management. The first case is a 35-year-old woman who had a left breast tumor. Fine needle aspiration cytology (FNAC) showed ML. mastectomy was performed without any adjuvant chemotherapy. histology revealed diffuse large B-cell lymphoma of REAL classification. Seventy one months after surgery, lesions indicating relapse were detected in nodes of the right axilla, mediastinum and para-aorta.She underwent eight cycles of CHOP regimen, but 1 month after the chemotherapy a brain metastasis was detected. The patient then received a high-dose methotrexate regimen with whole-skull irradiation. The second case is a 47-year-old woman who had anterior neck swelling and bilateral breast tumors. histology of the tumor revealed diffuse large B-cell lymphoma. The patient underwent eight cycles of CHOP regimen and high-dose chemotherapy (HDC) with peripheral blood stem cell transplantation (PBSCT). Forty eight months after the PBSCT, there is no evidence of disease. The third case is a 38-year-old woman who had a right breast tumor. FNAC of the breast tumor showed ML and a CT scan of the chest revealed lymphadenopathy at the crus of the diaphragm. histology of the tumor revealed low-grade B-cell lymphoma of MALT type. The patient underwent six cycles of CHOP regimen and HDC supported by PBSCT. Eighteen months after the PBSCT, relapse lesions were detected in nodes of the neck, mediastinum and renal hilum. The patient received nine cycles of a THP-COP regimen.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
6/183. Intraoperative cytodiagnosis of metastatic brain tumors confused clinically with brain abscess. A report of three cases.BACKGROUND: Cystic lesions of the brain may have diverse etiologies, ranging from true cysts to malignant tumors with cystic degeneration. Preoperative determination of the exact nature of them as well as intraoperative diagnosis may be sometimes difficult or even impossible. sensitivity and specificity of diagnosis will be improved by introducing new methods or combining traditional procedures. CASES: Three metastatic brain carcinomas with primary sites of breast, pancreas and prostate presented as cystic lesions and were confused clinically with abscess. Intraoperative frozen section was not revealing. Cytologic study of sediments of aspirated fluid uncovered malignant cells. CONCLUSION: When combined with frozen section, intraoperative cytologic studies in the form of crush preparation, fine needle aspiration or evaluation of aspirated fluid in cystic lesions (as in our cases) can improve diagnostic accuracy by detecting important diagnostic features that otherwise may be missed.- - - - - - - - - - ranking = 10keywords = brain (Clic here for more details about this article) |
7/183. limbic encephalitis and antibodies to Ma2: a paraneoplastic presentation of breast cancer.A patient with atypical medullary breast cancer is described who presented with symptoms of limbic encephalitis. The patient's serum and CSF contained antibodies that reacted with the nervous system and the tumour. These antibodies recognised Ma2, a neuronal protein related to paraneoplastic limbic and brainstem encephalitis in men with testicular tumours. This report highlights the importance of testing for paraneoplastic antineuronal antibodies in cases of unexplained limbic encephalitis and suggests screening for breast cancer in women with antibodies predominantly directed to Ma2.- - - - - - - - - - ranking = 1.4034020159782keywords = brain, nervous system (Clic here for more details about this article) |
8/183. Chemotherapy-induced complete regression of choroidal metastases and subsequent isolated leptomeningeal carcinomatosis in advanced breast cancer: a case report and literature review.Choroidal metastases from breast cancer represent an unusual metastatic presentation that has been traditionally treated with radiation therapy. Herein, we report a case of metastatic breast cancer presenting with pulmonary, cutaneous, lymph node and symptomatic choroidal metastases treated with systemic combination chemotherapy incorporating docetaxel and mitoxantrone without induction or consolidation radiation therapy to control visual symptoms from choroidal metastases. The patient experienced a durable complete remission in all metastatic sites that was maintained for 21 months since the initiation of chemotherapy, afterwhich she developed isolated leptomeningeal carcinomatosis managed successfully with intensive intrathecal methotrexate and whole brain irradiation leading to a new complete remission maintained until this report; 11 months after its presentation. This is the first case to our knowledge reporting complete regression of choroidal metastases with docetaxel-based chemotherapy as the only treatment modality and subsequent isolated leptomeningeal carcinomatosis recurrence.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
9/183. Seven cases of breast cancer recurrence limited to the central nervous system without other visceral metastases.We report 7 rare cases of recurrent breast cancers who presented with central nervous system (CNS) metastases as the initial relapse site without any other organ metastases. The average age of the patients at surgery was 42.6 years old of age (median 45:range 32-60), and 6 of the 7 cases (86%) were premenopausal. The mean disease-free period was 25.7 months (median 22, range 2-60 months). The primary tumors were all invasive ductal carcinomas. The estrogen receptor and progesterone receptor status of the 3 tumors available for study were all negative. The metastatic CNS lesions included the cerebrum (4 cases), cerebellum, cervical spinal cord, and meninges. In 6 out of these 7 cases (86%), the CNS metastasis was the initial recurrent lesion. Multidisciplinary treatments including surgery, radiotherapy and systemic or intrathecal chemotherapy were given. Although the mean survival time from clinical manifestations of the metastases of the 4 deceased patients was 20 months (median 20.5; range 6-33), one patient treated with surgery and radiotherapy is been still alive18 years later. These cases were also notable for the fact that the only metastatic site was in the CNS only during the entire clinical course, except for 2 cases, one with ocular adnexa metastasis, and the other with cervical lymph node metastasis. Premenopausal patients with negative hormone receptor status are more likely to develop this type of recurrence, regardless of the histological type. It is necessary to pay attention to neurological symptoms and signs during follow-up of breast cancer patients.- - - - - - - - - - ranking = 7.8983617761567keywords = central nervous system, nervous system (Clic here for more details about this article) |
10/183. A case of primary squamous cell carcinoma of the breast with rapid progression.Primary squamous cell carcinoma of the breast is a rare disease for which no definite treatment or prognosis has been established. This report describes our experience with one case of primary squamous cell carcinoma of the breast that ended in death after rapid progression. The patient was a 58 year old woman who visited our hospital complaining of a growing tumor and pain in the right breast. Ultrasonographically the tumor consisted of solid tumor and a large cyst. Squamous cell carcinoma was diagnosed by fine-needle aspiration cytology. Neoadjuvant CEF was given, but the tumor continued to grow, so CEF was discontinued after one course and modified radical mastectomy was performed subsequently. There was no evidence of metastasis to lymph nodes. About 5 months post operatively CT of the head and chest X-ray demonstrated metastatic lesions in the brain and lungs. Resection of the cerebral tumor was performed. About 1 month after the operation, however, a new metastatic brain tumor was found and the patient later died.- - - - - - - - - - ranking = 2keywords = brain (Clic here for more details about this article) |
