1/35. Bilateral trochlear nerve palsy associated with cryptococcal meningitis in human immunodeficiency virus infection.This is the report of a case of bilateral trochlear nerve palsy secondary to cryptococcal meningitis in a 34-year-old woman with acquired immune deficiency syndrome. Based on clinical and neuroradiologic findings, it is concluded that in the present case, a postinflammatory shrinking of the arachnoid has stretched the fourth cranial nerves at their point of emergence from the dorsal surface of the brainstem.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
2/35. P-ANCA-positive Wegener's granulomatosis presenting with hypertrophic pachymeningitis and multiple cranial neuropathies: case report and review of literature.An autopsy case of hypertrophic pachymeningitis and multiple cranial neuropathies is reported. A 53-year-old woman with paraplegia and various neurological signs which developed over a 2 year period was diagnosed as having an epidural mass with thickened dura mater extending from the lower cervical to the thoracic spinal cord. In addition, bilateral episcleritis, blephaloptosis, and blindness of the right eye with various cranial nerve deficits were found to be caused by the mass lesions involving the paranasal sinuses, orbit, and the cavernous sinus. Perinuclear antineutrophil cytoplasmic antibody (p-ANCA) was positive, but cytoplasmic antineutrophil cytoplasmic antibody (c-ANCA) was negative by enzyme-linked immunosorbent assay. The partially removed epidural mass with hypertrophied dura mater and biopsy of the paranasal lesions showed chronic granulomatous inflammation with vasculitis. The remaining lesions resolved with steroid therapy with remarkable neurological improvement. The positive p-ANCA test, paranasal involvement, the report of a similar histopathological case and a review of the literature on granulomatous pachymeningitis suggest the presence of p-ANCA-positive Wegener's granulomatosis with central nervous system involvement characterized by hypertrophic pachymeningitis and/or multiple cranial neuropathies.- - - - - - - - - - ranking = 215.93563279533keywords = pachymeningitis, meningitis (Clic here for more details about this article) |
3/35. Chronic granulomatous meningitis with multiple cranial nerve lesions hydrocephalus, stroke, sinus thrombosis, and epilepsy.Most frequently, chronic granulomatous meningitis (CGM) is caused by infectious agents. However, in some cases the cause of CGM remains undetermined. It is unclear whether antimicrobial agents, including antituberculous drugs, are helpful in such cases. We describe a 61-year-old man who had multiple cranial nerve lesions, epilepsy, sinus thrombosis, stroke, and hydrocephalus attributable to CGM. Repeated extensive search for a causative agent in the cerebrospinal fluid (CSF) and the meninges remained negative. Only a single culture of the sputum revealed growth of mycobacterium tuberculosis, which prompted antituberculous therapy with isoniazid, rifampicin, and ethambutol. After 6 months of therapy, neurologic abnormalities were slightly improved. We conclude that antimicrobial/ antituberculous agents have only a minor short-term effect in long-lasting CGM of undetermined cause.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
4/35. Leptomeningeal glioblastoma presenting with multiple cranial neuropathies and confusion.glioblastoma multiforme (GBM) is the commonest primary malignant neoplasm of the CNS. Usually, patients present with seizures and headache but in the elderly, confusion and generalised cognitive decline are more frequently the initial features. Multiple cranial nerve lesions as a manifestation of leptomeningeal meningitis is a rare presentation of GBM. The diagnosis is not often suggestive on either brain computed tomography (CT) or magnetic resonance imaging (MRI) and is usually confirmed by cerebrospinal fluid (CSF) cytology or histology. We describe the case of an 80-year-old man, who presented with multiple cranial nerve palsies and confusion secondary to leptomeningeal gliomatosis, in whom GBM was detected along the intra-ventricular lining of the left lateral ventricle at ventriculoscopy, in the absence of a distinct parenchymal lesion.- - - - - - - - - - ranking = 0.2keywords = meningitis (Clic here for more details about this article) |
5/35. Pituitary abscess presenting with cranial nerve paresis. Case report and review of literature.Non-adenomatosus lesions of the pituitary represent a small part of the intrasellar processes and they have heterogeneous presentation. Making a precise diagnosis is of great importance, as it may lead to more efficient management. A 65-year-old man was admitted to the hospital because of headache and right cranial nerve III palsy. Basic laboratory work-up was normal whereas endocrinological assessment revealed hypopituitarism without diabetes insipidus. Plain radiography showed an enlarged sella and frontal and paranasal sinusitis. Computed tomography (CT) and magnetic resonance imaging (MRI) of the sella revealed an intrasellar lesion with extension to the sphenoid and cavernous sinuses as well as the suprasellar region, exerting pressure on the optic chiasm. On T1-weighted images the mass had a low-intensity signal with a smooth enhancing rim with bright signal. Given the presence of multiple sinusitis and imaging characteristics a pre-operative diagnosis of pituitary abscess was made. The patient was operated via transphenoidal route and purulent material was drained out. Cultures of the material were positive for staphylococcus aureus. Antibiotics as well as cortisol replacement therapy were given. Three months later hypopituitarism persisted but there was significant improvement in the neurological findings. We report a case of an unusual presentation of a pituitary abscess. High index of suspicion, the presence of associated conditions such as pituitary tumors, meningitis or sinusitis, as well as diabetes insipidus and specific imaging features are the main diagnostic clues. Pre-operative diagnosis, which will lead to prompt antibiotic therapy and transphenoidal drainage, can decrease high mortality and morbidity associated with this disease.- - - - - - - - - - ranking = 0.2keywords = meningitis (Clic here for more details about this article) |
6/35. dysarthria as the isolated clinical symptom of borreliosis--a case report.This report presents a case of dysarthria due to hypoglossal nerve mono-neuropathy as the only consequence of neuroborreliosis. The 65-year-old man with a seven-months history of articulation disturbances was examined. The speech of the patient was slow and laboured. A slight weakness of the muscles of the tongue (left-side) was observed. The patient suffered from meningitis due to borrelia burgdorferi infection in 1999 and initially underwent a successful antibiotic treatment. Detailed radiological investigation and psychological tests were performed and co-existing neurological diseases were excluded. To describe profile of speech abnormalities the dysarthria scale was designed based on S. J. Robertson dysarthria Profile. There were a few disturbances found in self-assessment of speech, intelligibility, articulation, and prosody but especially in the morphology of the articulation muscles, diadochokinesis, the reflexes (in the mouth, larynx and pharynx). Needle EMG examination confirmed the diagnosis of mono-neuropathy of left hypoglossal nerve. The study confirms the fact that neuroborreliosis may evoke chronic consequences.- - - - - - - - - - ranking = 0.2keywords = meningitis (Clic here for more details about this article) |
7/35. rheumatoid factor positive hypertrophic cranial pachymeningitis in association with hypopituitarism and multiple cranial nerve palsies.This is the first report of a patient presenting with rheumatoid factor (RF) positive hypertrophic cranial pachymeningitis (HCP) in association with hypopituitarism and multiple cranial nerve palsies. Our patient developed palsies of the left II and III, bilateral VI and VII, and right IX, X, and XII cranial nerves. A stimulation test showed hypopituitarism due to hypothalamic failure. The patient was seropositive for RF but had no multiple joint pain or deformities. magnetic resonance imaging (MRI) showed thickened dura of the sellar and parasellar region, hypothalamus, bilateral cavernous sinuses and the tentorium all of which were enhanced by gadolinium (Gd). Treatment with prednisone improved clinical symptoms and MRI findings concomitant with reduction of RF titer. Although the exact mechanism of HCP has not been clearly elucidated, the present case suggests an autoimmune mechanism associated with RF.- - - - - - - - - - ranking = 154.23973771095keywords = pachymeningitis, meningitis (Clic here for more details about this article) |
8/35. Hypertrophic pachymeningitis: varied manifestations of a single disease entity.Hypertrophic pachymeningitis is a unique clinical entity characterised by fibrosis and thickening of the duramater with resulting neurological dysfunction. Three cases of this entity are described. Presenting features were headaches and cranial neuropathies in two patients and predominantly cerebellar dysfunction in the third. One of the patients also had evidence of spinal involvement. Lower cranial nerves were chiefly involved in two patients whereas optic nerve was the predominantly affected nerve in one. Except for the presence of rheumatoid arthritis in one of the patients, we could not document clinical or biochemical evidence of any predisposing infective, inflammatory or infiltrative condition in the other two. All three patients had characteristic changes on imaging suggestive of thickened and enhancing duramater. Although variable steroid responsiveness was seen in all the three patients, tendency towards steroid dependence was evident. The clinical presentations, causes, radiological features, management options and differential diagnosis of this unique clinical syndrome have been discussed.- - - - - - - - - - ranking = 154.23973771095keywords = pachymeningitis, meningitis (Clic here for more details about this article) |
9/35. Unusual presentation of carcinomatous meningitis: case report and review of typical CSF findings.This paper describes a previously unreported clinical onset of carcinomatous meningitis with bilateral deafness. Typical changes in the cerebrospinal fluid aside from positive cytology findings are reviewed. In cases of suspected carcinomatous meningitis the clustering of increased CSF protein, lactate, decreased glucose, and a high opening pressure is suggestive of the diagnosis.- - - - - - - - - - ranking = 1.2keywords = meningitis (Clic here for more details about this article) |
10/35. Standard and novel radiotherapeutic approaches to neoplastic meningitis.Neoplastic meningitis usually occurs late in the natural history of cancer. Adequate staging and assessment of the patient's overall reserves and prognosis are crucial in determining whether aggressive treatment is justified. Although radiotherapy remains the single most effective treatment, it is considered palliative for epithelial cancers and is generally directed to sites of bulky disease that obstruct the flow of cerebrospinal fluid or cause neurologic dysfunction. Such diseases as leukemia, medulloblastoma, and germinoma are exceptions that can be treated definitively with craniospinal irradiation. Innovations in conformal therapy may help to reduce the significant amount of myelosuppression associated with spinal irradiation. The main long-term toxicity associated with whole-brain irradiation (WBI) is dementia resulting from leukoencephalopathy, which may be exacerbated when WBI is given in combination with chemotherapy. A case report highlighting the use of radiotherapy for palliation in a patient with neoplastic meningitis is presented at the end of this article.- - - - - - - - - - ranking = 1.2keywords = meningitis (Clic here for more details about this article) |
