OBJECTIVE Because oligodendroglioma are infiltrative tumors, the Mac Donald's response criteria, usually used for solid and contrast-enhanced tumors, seem not to be adapted. To precise more relevant radiological criteria, the radiological response of oligodendroglioma to PCV chemotherapy was evaluated on T2 weighted-MRI sequences only. METHODS 25 patients(More)
We report a case of an intramedullary thoracic primary melanocytic tumor of the leptomeninges in a 38-year-old woman. According to the WHO classification, the lesion showed the histological features of a meningeal melanocytoma. Two local recurrences were successively operated on, two and three years after the first surgery respectively. The patient died of(More)
OBJECTIVES Photodynamic therapy is a new focal therapy for prostate cancer. METHODS In this technique, a photosensitising agent is introduced intravenously, then activated by local laser illumination to induce tumour necrosis. Treatment efficacy is assessed by magnetic resonance imaging (MRI). RESULTS AND CONCLUSIONS We illustrate specific(More)
Rare forms of demyelinating disease such as Balò's concentric sclerosis or Schilder's disease may simulate brain tumors, both clinically and on the computed tomography (CT) and magnetic resonance imaging (MRI). Even the histopathological diagnosis after a biopsy is not entirely reliable. We report three cases of pseudotumoral demyelinating disorders having(More)
Post-traumatic intracranial aneurysms are rare entity, which can appear following even benign head injuries. Their clinical manifestations are various, from a typical SAH to an uncommon intracerebral hematoma. Medical history runs usually from a couple of days to several years. Two cases of intracranial aneurysm have been observed from 1995 to 1998. The(More)
