Introduction. The aim of this study was to determine the frequency of pseudoprogression in a cohort of glioblastoma (GBM) patients following radiotherapy/temozolomide (RT/TMZ) by comparing Macdonald criterial to Response Assessment in Neuro-Oncology (RANO) criteria. The impact on prognosis and survival analysis was also studied. Materials and Methods. All… (More)
Juvenile psammomatoid ossifying fibroma (JPOF) is an uncommon benign fibro-osseous lesion predominantly arising in the paranasal sinuses and orbits of children and young adults. We report a case of JPOF involving the paranasal sinuses and orbit in a 15-year-old boy that presented due to progressive proptosis and downward displacement of the left eye. The… (More)

We describe a case of a 48-year-old woman who presented with neck pain and progressive left arm weakness. Magnetic Resonance Imaging showed a cervical intramedullary cystic lesion. The lesion was removed and neuropathological analysis revealed an ependymal cyst.
BACKGROUND The simultaneous occurrence of multiple intracranial neoplasms has been reported, especially in genetic familial syndromes and after cranial irradiation. In the absence of these etiologic factors, some reports showed simultaneous occurrence of glioblastoma and meningioma but the association between gliosarcoma and meningioma is unknown. CASE… (More)
BACKGROUND Infection constitutes a serious adverse event in deep brain stimulation (DBS) surgery, being responsible for difficult therapeutic decisions that may ultimately involve the removal of implanted material. Some cases begin with skin erosion and wound dehiscence of the retroauricular incision, which is one of the most fragile points. Several… (More)
