Merkel cell carcinoma (MCC) is a malignant neuroendocrine tumor of the skin that demonstrates a remarkable tendency to metastasize. However, only a few cases of MCC brain metastases have been reported in the literature. We here present a unique case of a pituitary metastasis of MCC in a 65-year-old patient with a history of pituitary adenoma. This case is(More)
Two cases of spontaneous intrauterine ping-pong fractures are reported in newborns delivered by cesarean section. Skull fractures occurred with no evidence of extrinsic trauma or cephalopelvic disproportion. Subsequent clinical follow-up at 6 and 12 months revealed normal skull reshaping and growth, with no associated neurological deficits. Spontaneous(More)
INTRODUCTION Somatosensory evoked potential (SEP) recordings and continuous electroencephalography (EEG) are important tools with which to predict Glasgow Outcome Scale (GOS) scores. Their combined use may potentially allow for early detection of neurological impairment and more effective treatment of clinical deterioration. METHODS We followed up 68(More)
BACKGROUND The particular biomechanics of the upper cervical spine require, when trauma occurs, careful evaluation of the stability of the lesions, in order to guarantee the best possible therapeutic and prognostic approach. To date, there has been no uniformity of opinion in merit, especially with reference to treatment of odontoid fractures. It is(More)
Pleomorphic xanthoastrocytoma (PXA) is a rare primary low-grade astrocytic tumor, recently classified as a neuroglial tumor. It generally occurs in children and young adults and shows benign behaviour (WHO II), although an anaplastic variant and malignant potential have been described. Pleomorphic xanthoastrocytomas with malignant transformation have been(More)
OBJECT Massive intraventricular hemorrhages (IVHs) require aggressive and rapid management to decrease intracranial hypertension, because the amount of intraventricular blood is a strong negative prognostic predictor on outcome. Neuroendoscopy may offer some advantages over more traditional surgical approaches on outcome and may decrease the number of shunt(More)
BACKGROUND This study aims to assess the diagnostic value of multivoxel 2D chemical-shift imaging (CSI) proton magnetic resonance (MR) spectroscopy combined with perfusion magnetic resonance imaging (MRI) in the differential diagnosis and grading of brain tumors by comparing neuroimaging data with histopathological findings obtained after resection or(More)
The authors present the case of a dumbbell-shaped malignant psammomatous melanotic schwannoma of the upper cervical spine involving the C-2 sensory root. The family of the patient had a history of other malignant stromal tumors, without the Carney complex genetic pattern. The 30-year-old female patient complained of experiencing cervical pain and cervical(More)
INTRODUCTION Transnasal endoscopic repair of cerebrospinal fluid (CSF) fistulas is recommended for patients with CSF leaks who do not respond to conservative treatment. It is a safer and more successful alternative to transcranial surgery. PATIENTS AND METHODS We present our experience on using transnasal endoscopy for the repair of anterior skull base(More)
BACKGROUND The aim of this study is to assess whether a complete analysis of all early cortical somatosensory-evoked potentials (SEPs) components and computed tomography (CT) scan features can provide a better prognostic measure than the early cortical component N20/P25 alone, in patients with severe head injury. MATERIALS AND METHODS We studied 81(More)
