BACKGROUND The meningeal hemangiopericytoma (MHPC) is a vascular tumor arising from pericytes. Most intracranial MHPCs resemble meningiomas (MNGs) in their clinical presentation and histological features and may therefore be misdiagnosed, despite important differences in prognosis. MATERIALS AND METHODS We report 8 cases of MHPC and 5 cases of MNG(More)
BACKGROUND Glioma is a heterogeneous central nervous system (CNS) tumor group that encompasses different histological subtypes with high variability in prognosis. The lesions account for almost 80% of primary malignant brain tumors. The aim of this study is to extend our understanding of the glioma epidemiology in the central Tunisian region. MATERIALS(More)
BACKGROUND PA is a grade I glial tumor that mostly occurs in children. However, although apparently similar to paediatric PA, adult PA presents a different clinical follow-up that could arise from specific molecular alterations. A variety of genetic alterations have been identified as diagnostic or prognostic glioma molecular markers. MATERIAL AND METHODS(More)
For a long time the imaging diagnosis of spine disease was based on conventional radiology (plain radiography, myelography and arteriography). The recent employment of MRI had changed the study of spine disease thanks to an excellent contrast and a multiplanar approache. In fact, nowadays MRI is the most sensible technic for a combined study of spine(More)
Cerebral hytatid cysts (HC) are extremely rare, forming 2% of all intra cranial space occupying lesions even in counties where the disease is endemic. HC diagnosis is usually based on a pathognomonic computed tomography (CT) pattern. In order to assess the value of MR we reviewed the CT (n=25) and magnetic resonance (MR, n=4 including diffusion and proton(More)
PURPOSE The MGMT gene encodes a DNA repair enzyme that counteracts with chemotherapy efficiency, specifically with alkylating agents such as temozolomide (TMZ). It is well established that MGMT methylation should be screened as a predictive marker for TMZ in glioblastoma, and we thus aimed to determine a reliable and practical diagnostic method of MGMT(More)
Calcification of the cervical ligamentum flavum is a rare entity observed exclusively in Japanese people. We report a new case in a 65-year-old man from Tunisia who presented with symptoms of cervical myelopathy with mild tetra paresis, sensory abnormalities and dysuria. Magnetic resonance imaging (MRI) showed a posterior compression of the spinal cord at(More)
A three year old child who had been suffering from oral candidiasis since the age of 1 year presented with osteitis of the clavicle, 2 cerebral frontal abscesses and an occipital abscess which extended across the calvaria and was associated with osteolysis. Histological and microbiological studies following surgery confirmed the diagnosis of candidiasis in(More)
The authors report, after a follow-up period of two years, a case of intramedullary congenital epidermoid cyst treated surgically. The patient, a 21 year-old man, presented with a seven year history of motor disturbances of his left lower limb and more recent urinary incontinence. The diagnosis of an intramedullary tumor was provided by a myelogram and a(More)
BACKGROUND Spinal epidermoid cysts are rare tumors and they are exceptionally intramedullary. AIM Report of news cases CASE REPORT The diagnosis is established by magnetic resonance imaging and the treatment is surgical. The prognosis is generally good, with possible recurrence after many years. The author report five new cases of intramedullary(More)
