Previous findings have shown that saffron (Crocus sativus L.) extract and its active constituents produce antinociceptive effects in the rat models of orofacial pain. In the present study, the central H2 histaminergic and alpha-2 adrenergic receptors involvement in crocetin-induced antinociception in orofacial formalin pain in rats was evaluated.The guide cannula was implant...

Disproportionate enlargement or isolation of the fourth ventricle are rare complications of ventriculo-peritoneal shunt for post-haemorrhagic hydrocephalus. Obvious features such as ataxia may indicate raised intracranial pressure in the posterior fossa. The child may, however, present with less specific signs of vomiting, anorexia, and lethargy and these symptoms may be misinterpreted as secon...

BACKGROUND Fourth ventricle mass lesion in neurosarcoidosis is very rare and difficult to be diagnosed pathologically. We report a rare case of progressive hydrocephalus associated with neurosarcoidosis mass lesion located at the fourth ventricle outlet and suprasellar region. CASE DESCRIPTION A 23-year-old man had a disturbance of consciousness and neck stiffness with fever. Magnetic resonan...

Primary central nervous system lymphoma (PCNSL), a highly malignant and infrequent tumor, is rarely found within the fourth ventricle. Here we report a case of isolated lymphoma within the fourth ventricle: a 61-year-old male presented with headache, mental disorder, abnormal gait and urinary incontinence. Based on the clinical symptoms and neuroimage, He was initially diagnosed as choroid plex...

The floor of the fourth ventricle in the mouse was studied by scanning and transmission electron microscopy. 1. The fourth ventricular floor is covered by a simple layer of ependymal cells, the cytoplasm of which is characterized by numerous filaments and scanty ribosomes. 2. The ventricular surface of the ependyma is studded with numerous cilia and abundant microvilli. In the medial part of th...

A father and son presented ten years apart with a fourth ventricle ependymoma. The history, imaging and pathology are presented and the aetiology of familial ependymoma discussed.

mal cells and a subependymal plate composed of glial cells. Accordingly, these layers give rise to ependymomas, subependymomas, and subependymal giant cell astrocytomas (1). Hemangioblastomas are benign vascular tumors with an uncertain origin. They account for 12% of all intracranial tumors, and are a component of the von Hippel-Lindau syndrome in 30% of cases (2, 3). Hemangioblastomas usually...

background & importance: idiopathic stenosis of the foramina of magendie and luschka is a rare cause of obstructive hydrocephalus involving the fourth ventricle. case presentation: we reported the case of a 40-year-old woman who developed headaches and vertigo for several months and more recently gait disturbance. the ct scan showed quadri-ventricular hydrocephalus involving mainly the fourth v...

Neurocysticercosis is the most frequently observed parasitosis of the central nervous system worldwide. The fourth ventricle is the most frequent site of intraventricular infestation, a location that carries a higher risk for CSF blockage and intracranial hypertension due to CSF blockage. A great number of patients become shunt dependent which carries a poorer prognosis. We report on a case of ...

Objectives: The aim of the morphometric study was to examine the range in the normal size of the third ventricle in the North Indian population; males and in females living in Punjab and, assess the existence of its relationship with gender and age; and clinically correlate. Materials and Methods: MRI of 300 subjects living in North India was examined for various morphometric measurements of th...
