medulloblastoma is one of the most common primary tumors of the central nervous system of children but it is uncommon in adult age. we report a case of young male presented with a history of generalized headache that was found to have medulloblastoma with diffuse leptomeningeal involvement without prominent mass lesion. to our knowledge, our patient is the second reported case of medulloblastom...

OBJECTIVE To determine the incidence and risk factors for leptomeningeal metastasis after surgery for brain metastasis of solid tumors. METHODS Review of the records of all patients operated on for brain metastasis between January 1990 and August 1995. RESULTS In this period 28 patients underwent surgery for brain metastasis, of whom 27 were available for evaluation in this study. Median su...

BACKGROUND Leptomeningeal metastasis is a consequence of advanced solid malignancies and has limited treatment options. It is possible that it is becoming more common as the leptomeninges act as a sanctuary site for recurrence from systemic cancer. METHODS Potential targeted and immunotherapy agents for the most common types of solid-tumor leptomeningeal metastasis are reviewed, as are their ...

BACKGROUND AND PURPOSE Multifocal seeding of the leptomeninges by malignant cells, which is usually referred to as leptomeningeal carcinomatous metastasis, produces substantial morbidity and mortality. The diagnosis of leptomeningeal metastasis is usually established by cerebrospinal fluid (CSF) investigation, including cytology, cell counts, protein, glucose, and a tumor marker such as carcino...

Pulmonary large-cell neuroendocrine carcinoma (LCNEC) is a rare and malignant form of lung cancer with a poor prognosis for patients. The common sites of metastases are the liver, adrenal glands, bone and brain. LCNEC rarely metastasizes to the small intestine, ovaries, tonsils, mandible, vulva or spine. To the best of our knowledge, there have been no reports of leptomeningeal metastasis of LC...

We molecularly dissected leptomeningeal metastasis, or spread of cancer to the cerebrospinal fluid (CSF), which is a frequent and fatal condition mediated by unknown mechanisms. We selected lung and breast cancer cell lines for the ability to infiltrate and grow in CSF, a remarkably acellular, mitogen-poor metastasis microenvironment. Complement component 3 (C3) was upregulated in four leptomen...

BACKGROUND Melanoma has the highest rate of spread to the leptomeninges and the incidence of melanoma has been steadily rising. This article describes recent experience at the Lille University Hospital, between 2007 and 2011 and discusses the possibilities for treatment of leptomeningeal metastasis. PATIENTS AND METHODS Nine patients were diagnosed with leptomeningeal metastasis of melanoma. ...

RATIONALE Leptomeningeal metastasis from cervical adenosquamous carcinoma is extremely rare especially after radiotherapy for vertebral metastasis. PATIENT CONCERNS A 52-year-old woman with International Federation of Gynecology and Obstetrics (FIGO) stage IIB adenosquamous carcinoma of cervix presented with bilateral lower limbs weakening after 2 courses radiotherapy to thoracic vertebral me...

In low-grade glioma, metastasis is rarely seen. Few cases of leptomeningeal dissemination have been reported in children. Vertebral bone metastasis has not been reported so far. Herein is described the case of a pediatric patient with the diagnosis of pilocytic astrocytoma, and leptomeningeal dissemination detected at the time of diagnosis, who then received radiotherapy and chemotherapy upon d...

Leptomeningeal carcinomatosis, a not uncommon complication of non-small cell lung cancer, is associated with poor prognosis, and median survival is reported in case series as weeks to months. The advent of targeted therapy may have positively impacted the prognosis of such patients recently. Standard approaches to treatment of leptomeningeal metastasis include intrathecal chemotherapy with or w...
