1/239. brain metastasis as first manifestation of ovarian cancer.brain metastasis from ovarian cancer, a rare and highly dismal event, develops mostly during or after postoperative chemotherapy. This report documents the clinical findings and magnetic resonance imaging of an uncommon case who presented signs of increased intracranial pressure as a first manifestation. Histologic examination of removed brain lesion demonstrated ovarian origin, while no evidence of a locally invasive lesion was found at exploratory laparotomy ('tentative' surgical stage Ia). The possibility of ovarian origin should be always considered in a woman with brain involvement.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
2/239. Spontaneous intracranial hypotension.PURPOSE: To describe a patient with classic presentation of spontaneous intracranial hypotension and subsequent improvement with targeted epidural blood patch. methods: Report of one case and review of the literature. RESULTS: Examination of cerebrospinal fluid after lumbar puncture disclosed a reduced opening pressure, an increased level of protein, and lymphocytic pleocytosis. magnetic resonance imaging of the brain with gadolinium showed diffuse enhancement of the pachymeninges, no evidence of leptomeningeal enhancement, and chronic subdural fluid collection. Radionuclide cisternography demonstrated reduced activity over the cerebral convexities, early accumulation of radiotracer in the urinary bladder, and direct evidence of leakage at the cervicothoracic junction (C7-T1). Clinical, laboratory, and radiologic features were consistent with the diagnosis of spontaneous intracranial hypotension. Therapy with a targeted epidural blood patch resulted in the rapid resolution of symptoms. CONCLUSIONS: In this report, we describe a classic case of spontaneous intracranial hypotension in a 63-year-old man with an initial presentation of postural headaches, blurred vision, pain in the left eye, diplopia on left gaze, and neck soreness.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
3/239. December 1998--16 year old female with headaches, lethargy and a sellar/suprasellar mass.A 16 year female with a history of developmental delay and shunted hydrocephalus presented with two months of progressive headaches, lethargy and visual disturbances. An MRI of the brain revealed a sellar and suprasellar cystic mass which was absent on a previous MRI six years earlier. The pre-operative clinical diagnosis was pituitary adenoma vs. craniopharyngioma. Histologically, the fibrous wall of the ciliated epithelial-lined cyst was thickened by non-caseating granulomatous inflammation, hemorrhage, hemosiderin, and cholesterol clefts, consistent with cyst rupture. Rathke's cleft cysts are uncommon symptomatic lesions in young people, and must be distinguished from craniopharyngioma.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
4/239. Subarachnoid haemorrhage: difficulties in diagnosis and treatment.Aneurysmal subarachnoid haemorrhage is associated with a uniquely severe headache of acute onset. Classical cases are readily identified as such, although this is not always the case. Four cases who were admitted to a district general hospital within a 3-month period are presented, because they demonstrate a variety of presentations, management options, and outcomes.- - - - - - - - - - ranking = 103.50998876025keywords = haemorrhage (Clic here for more details about this article) |
5/239. Pseudo Chiari type I malformation secondary to cerebrospinal fluid leakage.cerebrospinal fluid (CSF) leakage may occur spontaneously, iatrogenically or from spinal trauma. Postural headache is the cardinal symptom; dizziness, diminished hearing, nausea and vomiting are additional symptoms. In neurological examinations cranial nerve palsies may be found. Due to low CSF pressure neuroimaging studies may reveal dural enhancement and vertical displacement of the brain. We describe a patient with the history of an uncomplicated lumbar discectomy at the level L4-5 and the typical clinical symptoms of intracranial hypotension. MRI of the craniocervical junction showed typical features of a Chiari type-I malformation. After neurosurgical ligation of a CSF leak at L4-5 caused by lumbar disc surgery, the patient was free of orthostatic headache. A repeated MRI showed a striking reduction of the previous downward displacement of the cerebellar tonsils and pons.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
6/239. Eosinophilic meningitis. An unusual cause of headache.Human parasitic infections are uncommon outside the tropical north but common in animals throughout australia. The rat lung worm, angiostrongylus cantonensis, can invade the human brain to cause a chronic meningitis with prolonged headache. This condition can be diagnosed by finding a high eosinophil count in cerebrospinal fluid (CFS), the lumbar puncture also provides symptomatic relief. The outcome is usually benign but death has been reported.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
7/239. The role of corticosteroids in the treatment of cerebral schistosomiasis caused by schistosoma mansoni: case report and discussion.A 26-year-old Brazilian man was admitted to The Toronto Hospital with a headache and visual scintillation. His last travel to brazil was five years previously. A computed tomography (CT) scan of the head showed an occipital mass with surrounding vasogenic edema. Occipital brain biopsy revealed schistosoma mansoni eggs. The patient was treated with two doses of praziquantel (20 mg/kg) and dexamethasone (10 mg). His symptoms and occipital mass resolved. Cerebral schistosomiasis is, in part, caused by the host's inflammatory response to Schistosoma. Modes of treatment have included surgical resection, the antiparasitic drugs oxamniquine or praziquantel, and corticosteroids. Corticosteroids may diminish granulomatous inflammation, thereby preventing further tissue destruction, and there is evidence that they also reduce ova deposition. Our review of the literature supports prompt medical therapy in patients with cerebral schistosomiasis. While the minimally or asymptomatic individual may be treated with praziquantel alone, clinicians should consider adjunctive therapy with corticosteroids for patients with prominent neurologic signs or symptoms or mass lesions with evidence of surrounding edema on a CT scan or by magnetic resonance imaging.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
8/239. brain parenchymal, subarachnoid racemose, and intraventricular cysticercosis in an Indian man.The coexistence of brain parenchymal cysts at various stages of evolution, both intraventricular and subarachnoid racemose, is reported in a patient with neurocysticercosis. The condition has a variety of presentations, depending on the location of the cyst. This case is of particular interest because of the rarity of this condition in india.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
9/239. Familial fatal and near-fatal third ventricle colloid cysts.BACKGROUND: Despite having a presumed congenital origin, familial cases of colloid cysts have been reported only rarely. The first case of a brother and sister with colloid cysts is reported here, and the relevant literature is reviewed. methods: A 25-year-old man presented with a 24-h history of headache and vomiting. He rapidly became unconscious and fulfilled the criteria for brain death on arrival at hospital. No surgical intervention was performed. RESULTS: The patient's sister presented at the age of 41 with headaches and rapidly became unconscious. The sister had urgent bilateral ventriculostomies. followed by transcallosal removal of a colloid cyst. CONCLUSIONS: These cases support the hypothesis that colloid cysts are congenital lesions and provide some evidence of a possible genetic predisposition to their formation. Sudden death remains a real risk for patients harbouring a colloid cyst.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
10/239. headache in ehlers-danlos syndrome.OBJECTIVE: ehlers-danlos syndrome (EDS) is a complex hereditary connective tissue disorder with neurologic manifestations that include cerebrovascular disorders and chronic pain. The clinical data collected on 18 patients with EDS and chronic headaches is reported. PROCEDURE: Clinical history, neurologic examination, computerized tomography of the head, magnetic resonance imaging (MRI) of the brain, and electroencephalogram (EEG). Headaches were classified according to the International headache Society and the patients were followed by the author for a minimum of 2 years. FINDINGS: Four patients had migraine with aura, four had migraine without aura, four had tension headaches, four had a combination of migraine and tension headaches, and two had post-traumatic headaches. Nine patients exhibited blepharoclonus but none had history of seizures and their EEGs were normal, ruling out eye closure epilepsy. Although one patient had a small right frontal angioma, a second had Arnold Chiari malformation type I, and a third had an old stroke, headaches did not clinically correlate with their central nervous system (CNS) lesions. CONCLUSION: Chronic recurrent headaches may constitute the neurologic presentation of EDS in the absence of structural, congenital, or acquired CNS lesions that correlate with their symptoms. Individuals with EDS may be prone to migraine due to an inherent disorder of cerebrovascular reactivity or cortical excitability. Additional studies are needed to elucidate the pathogenesis of headaches in EDS.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
